1 BAER'S POCHARD
Aythya baeri
Honshu (during 1 FONT winter tour, in 1998)
The Baer's Pochard is a poorly known species has a small, declining population. Estimates
of the total population are
about 10,000 individuals. Most occur on mainland eastern Asia, breeding in
southeastern Siberia and northeastern China, and wintering in China, Korea,
Myanmar (has been known as Burma), and eastern India.
2 BYRAN'S SHEARWATER
Puffinus bryani
The Byran's Shearwater was described in 2011, from a specimen that had been
collected in 1963 on Midway Atoll, northwest of Hawaii in the Pacific Ocean.
At that time, that small shearwater was thought to be a Little Shearwater.
Later, a second specimen was tagged and recorded on Midway in 1990.
In February of 2012, DNA tests on 6 specimens of Puffinus bryani found in the
Ogasawara Islands of Japan, alive and dead between 1997 and 2011, determined the
birds to be Bryan's Shearwaters. It is assumed that the species still
survives in the uninhabited Japanese Ogasawara Islands.
Another shearwater in the Ogasawara Islands is
not well known. It was considered as part of the Audubon's Shearwater.
It is now named the Bannerman's Shearwater,
and it is a Japanese endemic breeder only in the Ogasawara group of islands.
Some have recently referred to it by the name "Tropical
Shearwater".
3 SIBERIAN CRANE
Grus leucogeranus
Kyushu (during FONT winter
tours in 1997, 2000, 2001,& 2004)
The Siberian
Crane is a rarity in Japan. On occasion (as during the 4 years noted
above), a single individual winters at Arasaki, on the southern Japanese island
of Kyushu, with the combined approximately 10,000 Hooded & White-naped
Cranes.
The Siberian Crane is now classified as "critical" because it is
expected to undergo an extremely rapid decline in the near future, primarily as
a result of the destruction and degradation of wetlands in the areas of its
migration and wintering grounds. The wintering site, holding 95% of the
population, in China, is threatened by changes that will come about with the
Three Gorges Dam project.
The total population of the species is between 2,500 & 3,000, making it, at
this time, the 3rd rarest crane in the world.
The Siberian Crane is a large, white bird with black on its wings, is (as noted above), at this
time, the third rarest crane in the world (after the Whooping and the
Red-crowned Cranes).
It is probably, at this time, the most threatened of the world's cranes.
Until just over 20 years ago, in 1981, the Siberian Crane was believed to be
even more rare, and endangered. It was in that year that about 800 birds were
discovered to be wintering at Lake Poyan, China's largest freshwater lake, along
the Yangtze River. With that, the known population nearly doubled. Subsequent
field surveys showed the total population of the species to be from 2,500 to
3,000 birds.
Still the outlook for the species is precarious. According to the crane
specialist, George Archibald, "from the tundra to the subtropics, few
endangered species involve so many complex problems in so many countries as does
the Siberian Crane".
There are 3 populations of Siberian Cranes. All but a few of the maybe 3,000
birds belong to the eastern population, which breeds in northeastern Siberia,
and winters along the Yangtze River in China.
Another very small central population breeds in the lower basin of the Kunovat
River in western Siberia, and winters in the Indian state of Rajaasthan (most
regularly in the Keoladeo National Park). When this population was observed at
its wintering grounds in 1992-93, it included just 5 birds. Only 4 birds were
observed at the Kunovat breeding grounds in 1995.
The western population (also very small and threatened), which apparently held at 8 to 14 birds in the late 1980's and early 1990's, has wintered at a single site along the southern coast of the Caspian Sea in Iran. The exact location of the breeding grounds of that population is unknown, but it's thought to be in the extreme northern portion of European Russia.
Thus, 2 populations of this species are extremely vulnerable (on the verge of extinction). These populations have continually declined from just over 100 birds in the 1960's (when they were discovered).
The Siberian Cranes that have occurred in Japan as vagrants have been
wanderers, on occasion, from the larger eastern population of the species that
normally winters in China.
Actually, in the past, the Siberian Crane was a common winter visitor in Japan
on Kyushu prior to the Mejii Era. Throughout the 20th Century, it became an
accidental, but there were some occurrences from Hokkaido south to Okinawa. Most
in Japan, however, continued to be on Kyushu. Interestingly, there were single
birds in Hokkaido in Oct-Dec 1977 and May-Sep 1985. The latter was a summering
bird in the Kushiro district, where the resident Japanese population of
Red-crowned Cranes reside.
Where Siberian Cranes breed, huge distances separate nesting pairs. Within each 1000 square kilometers in the breeding range, there are only 1 or 2 pairs of cranes.
The Siberian is the most aquatic of all cranes, exclusively using wetlands for nesting, feeding, and roosting. The nests are in bogs and marshes. In migration and in wintering areas, the bird prefers to feed and roost in shallow wetlands. Preferred foods are roots, sprouts, and stems of sedges and other aquatic plants. It seldom forages above the water line.

Siberian Crane in Japan.
The species is truly an exciting rarity to see in Japan.
During FONT tours there, we've seen it 4 different years,
but never more than a single bird.

4 SPOON-BILLED SANDPIPER
Eurynorhynchus pygmeus
Amami (during
1 FONT winter tour)
The Spoon-billed Sandpiper was seen during one
FONT Winter Japan Tour on the southern Japanese island of Amami.
The Spoon-billed Sandpiper is an
overall very rare species, breeding in far eastern Siberia. It winters coastally
in Southeast Asia.
The global population of the species was, not long ago, in the early 2000s, estimated as under 4,000
birds. The population at the known breeding grounds was said to be
about 1,000 individuals, thus indicating a greater than 50 per recent reduction
in the last decade or so.
Not only is the global population of the species declining rapidly, there is
another problem: in that population, recently, there has been very little
recruitment of young birds.
Although breeding success is low, it seems that the main factor in the
Spoon-billed Sandpiper's decline appears to be the low rate of return to the
breeding grounds.
Data collected from 2003 to 2009 on birds at Meinypilgyno (the main breeding
site for the species in far-eastern, Siberian Russia), it is suggested that
recruitment into the adult breeding population was effectively zero in
all those years (2003 to 2009), except for 2005 & 2007.
When we first started at FONT to note the classification of the Spoon-billed
Sandpiper in the 1990s it was listed as "vulnerable".
The Spoon-billed Sandpiper was uplisted to the category of "critically
endangered" in 2008, when the total breeding population of the species
was thought to be from 150 to 320 pairs.
In 2009-2010, the estimate was sadly revised downward to from 120 to 200
pairs.
One factor that may be responsible for the decline of the Spoon-billed
Sandpiper has been the loss of resting and feeding areas along the migration
flyway for the bird. There are about 8,000 kilometers of coastline between the
bird's breeding grounds in Arctic Russia and its non-breeding grounds in
southeast Asia. That's a long distance traveled by the bird that's about 6
inches in length.
The particular site along the coast in South Korea where the largest-ever
concentration of migrating Spoon-billed Sandpipers was recorded is now
the site of the world's biggest reclamation project. That habitat, vital for
bird, has been lost.
Other tidal mudflats around the coast of the Yellow Sea are rapidly being lost
to agriculture, industry, and urban development.
Another factor in the bird's decline is that at its wintering grounds in Myanmar
(Burma) and Bangladesh, numbers of them have fallen victim to the trapping of
sandpipers by hunters.
And when a population is as small as it for the Spoon-billed Sandpiper,
any number lost by such practice is detrimental.
Starting in 2008, an international team of researchers has surveyed, each year
in January, in Myanmar the Arakan coast and that of the Gulf of Martaban, the
wintering population of Spoon-billed Sandpipers.
The coast of the Gulf of Martaban has become known as the most important
wintering site for the species with about 220 birds found in 2010/2011.
Based on data from the breeding grounds, that is about half the estimated world
population, and over twice as many birds as found at all the other known
wintering sites put together.
Although the trapping by local hunters in Myanmar, referred to above, does not
deliberately target Spoon-billed Sandpipers, they are caught as a "bycatch"
in nets set for larger birds or pegged close to the mud to catch retreating fish
as the tide goes out.
The 2010 survey confirmed this large-scale hunting and trapping along the
Gulf of Martaban. Hunters indicated trapping up to 350 waders (or shorebirds) in
a single night.
One morning in January 2010, a hunter brought the survey team a Spoon-billed
Sandpiper he had caught the previous night along with about 100 Red-necked
Stints.
The single Spoon-billed Sandpiper, still alive, was marked with a red
flag and released by a group of local children.
That same hunter also indicated that he had last caught a Spoon-billed
Sandpiper the previous August (in 2009). It was an immature bird.
Not only are young birds more likely than adults to fall victim to hunters, they
are also likely to be affected disproportionately because they are thought not
to return to the breeding grounds until they are two years old. Some, during
that time, are speculated to spend the entire intervening year in their
non-breeding
area.
In September 2012, at a global meeting in Korea of biologists and other
environmental scientists, a list was distributed of the "100 Most
Endangered Species in the World", referring to all life, animal and plant.
It was under the auspices of the International Union for Conservation of Nature,
and the Zoological Society of London.
In that list, the Spoon-billed Sandpiper was positioned as number #10, making it
the "most endangered bird species on Earth" in the opinion of that
group, and sadly a candidate, unless something is done, for extinction.

In 2012, the conservation group SOS,
"Save Our Species" was a partner in an innovative
project to boost the number of juvenile Spoon-billed Sandpipers at their
breeding grounds in Chukotka, in eastern Russia.
With the WWT, the "Wildfowl and Wetlands Trust", a IUCN
member working with the Moscow Zoo and "Birds Russia",
there was tremendous success, during the summer of that year, hatching, rearing,
and releasing 9 Spoon-billed Sandpiper chicks.
Those 9 chicks were hatched from 11 eggs carefully taken from the breeding
grounds on the tundra. They were monitored, hatched, and nourished in the nearby
village of Meinypil'gyno before being released. The project required constant
attention and effort. The fledglings gained strength living in an open-air
aviary designed to shelter the birds from predators. For added protection, a
guard kept vigil day and night.
The pioneering work is significant in that in the wild just 3 Spoon-billed
Sandpipers out of every 20 eggs survive long enough to start their 8,000
kilometer migration to southeast Asia.
Also, as part of the project, another 20
thumbnail-sixed eggs were transported from Arctic Russia to a WWT facility in
Slimbridge, England.
The first chicks were hatched there on July 4, 2012.
Of the 20 eggs that were brought to the UK, 18 chicks successfully hatched.
Those new birds were added to 12 fully-grown Spoon-billed Sandpipers that were
already at the WWT center, having been brought in at the start of the
conservation breeding program in November 2011.
The eggs, that were brought to England in 2012, were for more than 17 hours in
flight, transported by helicopter and airplane in a journey that took, totally,
7 days to complete.
One of the eggs cracked during an airport inspection and had to be sealed using
nail varnish.
When the Spoon-billed Sandpiper chicks hatched, they were about the size of a
large bumblebee.
The WWT hopes that the increasing size of the captive flock of Spoon-billed
Sandpipers in the UK would help trigger breeding behavior in the birds when they
would later reach maturity at two years of age.

5 PRYER'S
WOODPECKER (also called OKINAWA
WOODPECKER) (JPe)
Dendrocopos (formerly Sapheopipo)
noguchii
Okinawa (during FONT spring, summer & winter tours)
The Pryer's, or Okinawa Woodpecker was considered close to extinction in the 1930's.
Population estimates since
1950 have ranged from 40 to 200 birds, with the most recent estimate being of 90
birds.
This species has been found during every FONT tour in Okinawa.
The Pryer's, or Okinawa
Woodpecker
The Yambaru forest
(above) in northern Okinawa is the only place on Earth for the
Pryer's, or Okinawa Woodpecker and the Okinawa Rail (referred to later in
this list).
Both species have been found there during FONT Japan Tours
along with some other notable birds including the Amami Woodcock (also in
this list),
and other rare wildlife such as the Okinawa Spiny Rat and the Okinawa Flying
Fox.
The Okinawa forest, in the photo
above, known as "Yambaru" has been visited during over a dozen FONT
tours over the years.
A number of rare & special species live in that region. Most notable
among the birds are the very rare Pryer's Woodpecker and the Okinawa
Rail.
We've spent many hours, during our tours, both in the day and after dark,
exploring that forest. At night, in that forested area we were in the quest of
the rail, owls, and the Amami Woodcock that occurs in northern Okinawa in
addition to the more-northerly island of Amami.
A very rare mammal we've seen there during FONT tours, on one
occasion was the Okinawa Spiny Rat (in the list referred to previously,
with the Spoon-billed Sandpiper, of the "100 Most
Endangered Species in the World").
Another rare animal we've seen there is the Okinawa Flying Fox, Pteropus
loochoensis, a "megabat" in the Pteropodidae family.
It was previously listed as "extinct" by the IUCN, but because
the two known specimens are taxonomically uncertain and of "unknown
provenance", it was changed to "data deficient".
Our two sightings of the Okinawa Flying Fox were both very late in the
day, as it was getting dark.
Some taxonomists treat the Okinawa Flying Fox, Pteropus loochoensis,
as a subspecies of Pteropus mariannus, the Mariana Fruit Bat, with
a range on Pacific islands from the Japanese Ryukyu islands in the north, south
to Guam.
6 AMAMI
THRUSH (JPe)
Zoothera major
Amami
(during FONT spring,
summer & winter
tours)
In the mid-1990's, the breeding population of the Amami Thrush was estimated as being about
60 birds. The similar White's Thrush is smaller.
The Amami Thrush has a cheerful
song, delivered mostly in the morning, and similar to that of the Siberian
Thrush, another Zoothera species. The White's Thrush has a more mournful song
delivered mostly at night.
The Amami Thrush, found only on that island, is
confined to mature (over 60 years old), subtropical, evergreen forest, at an
altitude of 100 to 400 meters. It is a shy bird.
Species in Japan classified as
ENDANGERED:
7 ORIENTAL
STORK
Ciconia boyciana
Kyushu
(during 2 FONT winter
tours, very rare on Kyushu)
With a total population of about 2,500 birds, the Oriental Stork breeds only in
the Amur and Ussuri basins (along the border of Siberia and China), and winters,
mainly, in eastern & southern China.
The last Oriental Stork
of the breeding population that was in Japan died back in 1971. That was on the
main Japanese island of Honshu, near Kinosaki.
A few years before nesting Oriental Storks
were extirpated in Japan, a re-introduction program began, with some birds from
Russia.
In May 2007, for the first time since 1964, an Oriental Stork chick
successfully hatched in Japan. That was in that same area of Honshu, near
Kinosaki, where Oriental Storks previously
were.
Since then (in 2011), about 50 Oriental Storks
were living in the wild in wetlands and fields in that area.
A key part of the successful return of the Oriental Stork
in that area is that a program was initiated with local farmers for the growing
of rice without pesticides. Thus, the food of the storks, fish and frogs, have
again flourished, as have the storks and other birds too.
For an itinerary of an upcoming FONT tour to the place in Japan with Oriental
Storks, and without pesticides, go to:
A JAPAN TOUR IN THE SPRING FOR SOME SPECIAL BIRDS
8 CRESTED IBIS
Nipponia nippon
Late one afternoon, during the May 2010 FONT tour, near the city of Kanazawa, on Honshu, we went to a museum to see what was to be a most interesting exhibit about a bird, known in Japanese as the "Toki". Its English name is the Crested Ibis. Its scientific name is Nipponia nippon. "Nippon" means "Japan".
The Crested Ibis is one of the rarest of the world's birds. A few decades ago it seriously flirted with extinction.
When I began birding in
Japan in the early 1980s, my bird book, and nearly the only one available in
English, was "A Field Guide to the Birds of Japan" published by the
Wild Bird Society of Japan, with its second and last printing in English in
1983.
On the cover of that book was a color illustration of two Tokis,
or Japanese Crested Ibises, in
flight. I've never forgotten that cover illustration! And, yes, I have hoped to
somehow one day to see the bird!
Crested Ibis
In the text of that
"Field Guide to the Birds of Japan", regarding the Japanese
Crested Ibis (as it was called then), it was
stated:
"In 1981 all 5 wild birds (remaining in Japan) were captured on Sado
Island for cage breeding. In 1982, 1 male and 3 females were still alive in
cages on Sado. In 1981, 7 (wild) birds were found in (a remote part of central)
China." (Those 7 birds in China were 4 adults and 3 chicks.)
The last of the Crested Ibises born out of captivity in Japan died in
2003.
At the Crested
Ibis exhibit we visited in the Kanazawa museum, there
was a map on the wall showing what had been the distribution of the bird in
Japan. It struck me as quite interesting that historically a center of abundance
had been the picturesque Noto Peninsula where we had birded the previous day.
The birds, when there, favored rice paddies where they fed on frogs.
If, by some quirk, we had seen a Crested Ibis,
an ultimate rarity, when there, it would have made our rare Chinese Egret
that we had seen a few years previously in a rice field, "abundant" by
comparison!
Sado Island, by the way, the last home of the Japanese Crested Ibis
in Japan, is not far, really, as a bird would fly, from
the north end of the Noto Peninsula where we visited a lighthouse.
Also on the wall in the Kanazwa museum, there was a series of photographs, all taken about 3 to 4 weeks before our visit. In one of the photos, there was a baby Crested Ibis that had just been born in captivity.
In a newspaper, just before we left Japan, there was the not-so-good news that Crested Ibises that had been released into the wild on Sado Island, had, once again in 2010, failed to breed. Four pairs had laid eggs there in the spring of 2010. Ultimately, all of the nests were abandoned. Disturbance by crows seemed to be a significant factor. If the Crested Ibises on Sado had bred, it would have been the first successful breeding in the wild of that species in Japan in 34 years.
Some good news, however, is
that the population of Crested Ibises in China
has been steadily increasing. For the past 23 years, since when only 7
individuals were found, China has bred and protected the species.
By June 2002, the wild population in China numbered 140 birds, and the captive
population there in 2 breeding centers was about 130 birds.
The most recent population estimate in China is of about 500 individuals.
In Japan, the Crested Ibis historically, in the early 19th Century, was common and widespread. In the late 19th Century and through much of the 20th Century, it declined drastically.
As recently as the mid-20th Century, there were two wild populations of Crested Ibises on the Noto Peninsula. One group there, in 1957, consisted of 14 birds. By 1961, it was down to 3. It nested there for the last time in 1962. In 1964, a single bird remained, which was later to be moved to captivity on Sado Island in 1969.
On Sado Island, there were 27 wild Crested Ibises in 1941. The following decade, in 1957, there were only 11. The decline there continued until, as noted, the species became extinct in the wild in Japan in 1981.
Since 1985, Crested
Ibises from China have been transferred to Japan for
captive breeding.
Over 100 individuals are now in captivity, with some in zoos, and about 30 (that
is 29) at the Japanese Crested Ibis Preservation Center on Sado Island.
In September 2008, that center released 10 of the birds as part of its Crested
Ibis restoration program, which aims to have 60 ibises in the wild by 2015.
Hopefully, toward that end, the breeding success in Japan will improve, so there
would be a growing Japanese population as there has been in China.
An update:
In the spring of 2012, the first Crested Ibises
were born in the wild in Japan since 1976.
The first chick was seen in the camera (at the
nest) on April 22. It was the first of 3 chicks in the nest.
The parents were a 3 year-old male and a 2 year-old female. Both were released
from captivity in March 2011, among about 45 released Crested Ibises
known to be alive at that time (in the spring of 2012).
As of 2012, 78 Crested Ibises have been
released into the wild on Sado Island since September 2008.
9 BLACK-FACED SPOONBILL
Platalea minor
Honshu (during 1 FONT winter tour)
Kyushu (during FONT winter tours)
Amami (during 1 FONT winter tour)
Okinawa (during FONT winter tours)
The global population of the Black-faced Spoonbill is estimated as being about only 700 birds. It
breeds on small islands off the west coast of Korea, and in one province of
eastern China. It winters from southern Japan south to Taiwan, Hong Kong
(China), and Vietnam.

CRANE
Grus japonensis
Hokkaido ("Japanese Crane")
(during all FONT spring & winter tours on Hokkaido)
Kyushu
("Manchurian Crane")
(during 1 FONT winter tour, very rare on Kyushu)
The Red-crowned Crane is the 2nd rarest crane in the world, after the
Whooping Crane in North America.
The total Red-crowned Crane population in the wild has recently been estimated as
being from 1,700 & 2,000 birds.
As of 2011, the estimate of the global population of Red-crowned Cranes
was 2,750 individuals in the wild, but with only 1,650 of them being mature
birds.
In Japan, there is a resident population (information follows).
In mainland Asia, there is a migratory population that breeds in
northeast China and southeast Russia, and winters in Korea and China.
Recent numbers of wintering birds, in the mainland Asia population, have been:
600 to 800 in China
300 to 600 in North Korea (that number has been increasing)
200 to 300 in South Korea
Also notable in mainland Asia is that the first Red-crowned Crane ever
found in Mongolia occurred there in 2003.
In Japan, the current resident population of the Red-crowned Crane
is on the northern island of Hokkaido, and there only in the
southeast portion of that island. It occurred also in southwestern Hokkaido
until about a hundred years ago.
But now, southeast Hokkaido is the only place in Japan where the
Red-crowned Crane normally occurs.
At one time, it bred on all 4 of the main Japanese
islands, but it declined dramatically in Japan in the 19th Century. By 1890, it
remained in Japan only in Hokkaido.
A Red-crowned Crane in northern Honshu in June 2008 was the first
sighted on that island in a hundred years.
In the 1920's, the total Japanese population of the Red-crowned Crane was only about 20 individuals.
Since then, the number in Hokkaido, due to protection and artificial feeding (in
the winter), has increased, as noted below, to over 1,000 birds.
At the time of the first FONT tour in Japan, in 1993, there were 569 resident
Red-crowned Cranes in Japan on Hokkaido.
Just over a decade earlier
(when Armas
Hill made his first visit to Hokkaido to see Japanese, or
Red-crowned, Cranes), there were just over 300.
The following list shows how the population has changed
(increased) in Japan since then.

As noted above, there is a migratory population of the Red-crowned Crane on continental Asia in northeast China, eastern Siberia, and
Mongolia, wintering in
eastern China and Korea. In 2004, that population was determined to be
between 1400 and 1600 birds.
One of these
Red-crowned Cranes (a
"Manchurian Crane", rather than a
"Japanese Crane"), an immature bird, was seen on Kyushu (with
White-naped
Cranes &
Hooded Cranes) during the FONT February 2005 tour. It was the first such
occurrence of a Red-crowned Crane there in 37 years!
Years ago in Japan, a tradition developed with the folding of 1,000 paper
cranes. Doing so, a person petitioned "a crane" for happiness,
good luck, and a long healthy life. Strings of paper cranes were often hung at
temples and shrines.
In 2011, students around the world folded paper cranes to help raise
money for earthquake and tsunami victims in Japan.

13 SPOTTED
(or
NORDMANN'S)
GREENSHANK
Tringa guttifer
The Spotted, or Nordmann's Greenshank is very rare, breeding only
by the shores of the Sea of Okhotsk, and on North Sakkalin Island (north of
Japan) and possibly in the western Kamchatka Peninsula. In Japan, it is a rare
migrant.
14 BLAKISTON'S
FISH OWL
Bubo
(formerly
Ketupa)
b. blakistoni
Hokkaido (where it has been
seen during every FONT late-fall & winter tour; there have been 24 such tours)
This large and very rare Blakiston's Fish Owl occurs in southeastern Siberia (where there
may be a few hundred birds), China (where there may be up to a hundred birds),
and in central & eastern Hokkaido in Japan (where there's an estimated 120
birds). Its total population may thus be only in the hundreds, less than a
thousand birds.
Blakiston's Fish-Owl, Hokkaido, Japan
This bird is as extraordinary and formidable as any owl in the world. The
Blakiston's Fish Owl (as it has traditionally been called) is huge, with a
wingspan of about 6 and a half feet. It's larger than the Eagle Owl of Siberia.
Its legs are fully feathered. Its toes are bristly as are those of other fish
owls. It's interesting that structurally the Blakiston's Fish Owl has features
of both the "fish owls" (genus Ketupa) and the "eagle owls"
(genus Bubo).
In addition to Hokkaido, Japan, the species occurs only in far-eastern Siberia
(including Sakhalin and the southern Kurile Islands) and adjacent Manchuria, In
that area of mainland Asia, with a cold climate and severe winters, there may be
a few hundred birds. They inhabit dense, dark, primeval forests, either
coniferous, deciduous, or mixed, bordering lakes, rivers, and even the ocean
shore. They live in cold and difficult places for birds that eat mostly fish.
On the northern Japanese island of Hokkaido (a place where winters can
also be severe), Blakiston's Fish Owls are seriously endangered, confined to
relict areas of undisturbed forest. In 1983, less than 30 birds were recorded.
The following year, as survey workers gained more confidence of those guarding
secret locations, some 50 birds were located. During that year, 1984, however,
only 2 pairs were known to have bred successfully. Since then, in Hokkaido, with
successful nest box schemes in the forest, there has been some improvement in
nesting productivity. In the wild, nests are usually in large, hollow tress high
above the forest floor, but sometimes in decayed fallen trees closer to the
ground.
In the Siberian portion of the bird's range, Blakiston's Fish Owls have been
found at a density of 1 pair to every 7.5 to 9 miles of large river. In
Hokkaido, in all of the river valleys now occupied by owls, that figure is
less than 6 miles. Territories are occupied by birds for years. Individual owls
are so attached to their territories that a bird which loses its mate will
remain alone until another may arrive by chance.
Blakiston's Fish Owls are active throughout the night, as well as around dusk
and dawn. In the summer, they may do some hunting (to feed their young), during
lighter hours of the long summer days. In the winter, they're exclusively
nocturnal, emerging after sunset.
The territorial song is deep and resonant (although it does not travel as far as
that of the Eagle Owl). Males and females call together in duets.
Blakiston's Fish Owls, aptly, prefer fish as their primary food. In the late
summer, they feed on trout. In the autumn, they turn to salmon. Also, at times,
they eat: pike, catfish, burbot, and crayfish. In the spring, they live largely
on swarms of frogs that spawn in riverside marshes. Small mammals (such as hares
and martens) are also eaten, as well as an occasional duck, Hazel Hen, or
smaller bird. At some places, the owls feed along rocky seacoasts. Where they
exist in sufficient numbers (and that's not many places), they may gather during
the winter in small groups by openings in the river ice.
In Hokkaido, Japan, the Blakiston's Fish Owl, like the Brown Bear, was once held
in reverence. The fish-owl was known as "the god who defends the
village". Later, it suffered persecution, especially during the winter when
it was compelled to live close to openings in the ice, and, therefore, could
more easily be killed.
Today, under Japan's conservation laws, the Blakiston's Fish Owl is fully
protected.
Recently, the fish-owl in Japan is said to have suffered, ironically, from the
attention given to it by people who actually favor its protection and
well-being. This applies particularly to photographers (and there are many of
them in Japan) and other enthusiasts. There are some who don't realize the
damage they can cause the bird. Recent efforts to discourage them have included
trapping the owls and placing highly-reflective rings on their legs to make them
less attractive in flashlit photographs. It's become a matter of concern to
ornithologists that such "extreme methods" seem needed in order to
protect a bird that's on the verge of extinction in
Japan.

15 "OWSTON'S
(or
AMAMI)
WOODPECKER" (JPe)
Dendrocopos (formerly Picoides) (leucotos) owstoni
Amami (FONT
spring & winter
tours)
Endemic to Amami Island, the "Owston's Woodpecker" has traditionally been considered a
subspecies of the White-backed Woodpecker, as the largest and darkest race of
that wide-ranging species that occurs across the Palearctic. So distinctive is
this Amami resident, however, it may well be determined to be a full species.
Species in Japan classified as
VULNERABLE:
16 BAIKAL TEAL
Anas formosa
Honshu (during FONT winter tours)
Kyushu (during
FONT winter tours)
During the years of many of the FONT tours in
Japan, the Baikal Teal was classified by Birdlife International as
"vulnerable".
However, more recently, that organization has changed the classification of the
bird to that of a species of "least concern", as its population has
been increasing.
However, in this listing, we're keeping the species in this position as its
story is so interesting, and the status of the bird may yet change
again.
In the first decade of the 21st Century, the population of the Baikal
Teal has grown rapidly, and the species has not experienced the decline that
was predicted. That notwithstanding, the species remains potentially threatened
by a number of factors. it tends to congregate in very large flocks, and it
suffered rapid declines in many parts of its range in the 20th Century, due to
various threats.
At roost sites, with a large number of birds, significant numbers have died
recently during disease outbreaks, Also, dry rice paddies, that have been
favored feeding sites, have been converted to vegetable farms and other uses.
If evidence arises that such threats cause a decline, the Baikal Teal may
warrant uplisting.
The Baikal Teal h was classified at the end of the 20th century as "vulnerable"
as it had, for years, a rapidly declining population.
In the
early 20th Century, it was one of the most numerous ducks in eastern Asia, with flocks of several thousand
regularly reported. During the 1970's, and afterwards, there was a significant decline.
At least in part, that decline was thought to be due to excessive shooting or
netting in the bird's wintering range and along its migration routes.
The bird
has had a habit of gathering in large dense flocks, and making predictable daily
movements. There's an account of about 50,000 birds being netted during 20 days
by 3 hunters in Japan in 1947.
In South Korea, in the early 1990's, there were, at 2 locations, about 20,000
and 30,000 birds.
In Japan, during the last 50 years of the 20th Century, and into the 21st
Century, the Baikal Teal decreased from a status
of "abundant" in the winter to that of being "uncommon".
As the 21st Century began, wintering counts of the Baikal Teal in South
Korea increased dramatically, from about 20,000 birds (as noted in the early
1990s) to a total of 658,000 recorded during surveys in 2004, including 600,000
along the lower Geum River.
A very large number of 1.06 million birds was counted in January 2009, with
concentrations of over 20,000 birds at 6 different sites.
Thus, there has been a genuine population increase in South Korea, with a yearly
average increasing from 11,533 birds during the period 1999 to 2003 to 314,994
birds from 2005 to 2009.
This increase in the South Korean wintering population of the Baikal Teal
is thought by some to be linked an increase in newly reclaimed land and a
decline in hunting pressure.
In addition to the recent increase of the Baikal Teal population in South
Korea, there has also been lately, some large and recently-unprecedented numbers
at a few sites in China.
The Baikal Teal nests in river basins in northern & northeastern Siberia. The
male is an exquisitely-patterned bird.
17 SCALY-SIDED MERGANSER
Mergus squamatus
Honshu (during 2 FONT winter tours)
This Scaly-sided Merganser has a small and declining population. Its total population is estimated as between
3,500 and 4,500 individuals. Most breed in southeastern Siberia, in Khabarovsk
and Primorye. The breeding
population in China (in the northeastern Manchurian region of Heilungkiang) is estimated as 200 to 250 pairs, and
it is declining.
So, the Scaly-sided Merganser is a rare bird. And, overall, little is known
about it. The species is closely related to both the Common Merganser (or
Goosander) and the Red-breasted Merganser, with Its range overlapping with both
even during the breeding season.
The distribution within the nesting range is sparse, along fast-flowing rivers.
Territorial pairs occupy at least 4-kilometer stretches of rivers. Birds are
normally found in pairs, or in small family parties. If in groups, outside the
breeding season, the groups are small. The birds are shy and wary. Their flight
is fast and low.
Nests are in holes of old riverside trees. After nesting, the extent of
migration is uncertain. Some birds seem to go only to the lower reaches of the
rivers along which they bred (particularly those that flow from the eastern side
of the Sikote range in Siberia). Others have been recorded considerably further
away. There are old records of wintering birds in southwestern China. Also, the
bird has been recorded elsewhere in China (particularly in the valley of the
Yangtze), and in Korea, and more rarely in Japan, northern Vietnam, and northern
Myanmar (formerly Burma).
Outside the breeding season, the Scaly-sided Merganser can be encountered on
open lakes, but generally its preference is to be along rivers.
During the winter, the species is apparently rare, but regular, in Japan. It was
first discovered there in the mid-1980's. Also during that decade, the species
was found for the first time in Taiwan in winter.
Determining the population of this species has been difficult due to the
remoteness of the breeding range and the secretiveness of the bird. Surveys
conducted in Siberia, however, seem to have shown a considerable decrease since
the 1960's.

20 SHORT-TAILED ALBATROSS
(has also been called STELLER'S ALBATROSS)
(JPeb)
Phoebastria albatrus
pelagically, off Honshu
(during FONT spring &
winter tours twice, both times in 2000 - in January & in early
June)
The Short-tailed Albatross has a very small population, and a breeding range limited to 2
Japanese islands. Recent conservation efforts have resulted in a gradual
population increase.
But it is one of the rarest of the world's albatrosses, having recently flirted
with extinction. It was formerly abundant in the North Pacific, and seen even as
far away from the breeding sites in Japan as off the California coast of western
North America.
The global population of the Short-tailed Albatross, or the "Aho-dori"
as it is called in Japanese, following the 2006-2007 breeding season was
said to be 2,364 individuals, with 1,922 birds at the principal breeding colony
on Torishima Island, and 442 birds at the other more-southerly Japanese breeding
colony in the Senkaku Islands.
In 1954, there were only 25 birds (including at least 6 pairs) at
Torishima. In 2006, there were 426 breeding pairs on that
island.
Historical information follows below relating to the albatross colonies
at both Torishima and in the Senkakus.
The recent population figure given above was based upon the direct observation
of breeding pairs at Torishima, along with estimates of non-breeding birds at
sea and estimates of the breeding and non-breeding birds from the Senkakus
(Minami-kojima).
With that population figure noted here, the likely number of mature birds
is somewhere from 1,500 to 1,700 individuals.
Short-tailed Albatrosses have been seen during 2 pelagic ferry trips (as part
of FONT Japan Tours) off the east coast of Honshu, once in January and once in
early June.
Although the range of the bird in the Pacific is large, it seems that the Short-tailed
Albatross is most apt to be seen in areas of upwelling along the shelf
waters of the Pacific Rim, particularly along the coasts of Japan, eastern
Russia, the Aleutians and elsewhere in Alaska.
During the breeding season (at Torishima), from December to May,
the Short-tailed Albatross is in its highest density around Japan.
Satellite tracking has shown that during the post-breeding period,
females spend more time offshore from Japan and Russia, while males and
juveniles spend more time around the Aleutian Islands, the Bering Sea, and
off the coast of North America.
Juveniles have been shown to travel about twice the distance per day and spend
more time within the continental shelf than
adults.

The Short-tailed Albatross has
historically bred
on at least 11 small Japanese islands (in the Bonin, Izu, and Ryukyu (Nansei
Shoto) groups).
Away from its breeding sites, the bird has had on the open
ocean,
a
widespread range, as noted above, from Japan east to the Bering Sea and the west coast of North
America. Most of the records off Alaska, Canada, and the west coast of the
mainland US have been during June-November. The species was formerly common
along the western North American coast.
The Short-tailed Albatross was brought to the verge of extinction during the
late 19th and early 20th Centuries by plume hunters. The feathers were used for
stuffing quilts and pillows.
Another factor in the decline was habitat
disturbance on islands where the birds bred, particularly on Torishima (one of
the Izu Islands, 580 kilometers south of Tokyo). For years, it was only on the
volcanic ash slopes of that island that the species was known to breed.
Torishima was settled by humans in 1887. Until about 1900, from 10 to 50 people
lived there. The tame albatrosses were easily killed, as many as 100 to 200 a
day, up to 5 million birds in 12 years. In 1902, a major volcanic eruption on
the island killed many of the human inhabitants. The albatross population was
severely reduced, primarily by the slaughter of the birds, and secondarily by
the volcanic activity. In 1929, only about 2.000 birds remained on Torishima.
People who then recolonized the island conducted what would be the last great
massacre of the bird (nearly the entire remaining population of the species). By
1934, the Short-tailed Albatross was thought to be extinct.

Miraculously, in the early 1950's, 8 to 10 albatrosses appeared on Torishima.
As immature birds, over the years, they had been wandering the seas. During that
decade, numbers varied from 20 to 30.
In 1958, on Torishima, there were only 14
or 15 adults, 5 to 7 immatures, and 8 chicks.
Since then, there's been a slow
but steady increase in the population of the bird, with Torishima, most of the
time, the only known breeding location for the species in the world.
In 1960, all of the chicks (6 of them) were found killed. Only 22 adult birds
were found. But during the 1960's, the population began to rise more substantially to
over 50 birds.
In the 1970's it was to over 60. By 1979, the count was 95 birds
(& 22 chicks).
In March 1981, there were about 130 birds (& 34 chicks).
In November 1981, 63 eggs were found. In March 1982, there 21 chicks with about
140 adults and subadults.
The total population figures following 1979 were based
on observations at Torishima together with estimates of non-breeders away from
the colony. Thus, in 1982, the world population of the species was said to be
about 250 birds. Since 1979, over 50 eggs have been laid annually.
In 1991, the Short-tailed Albatross population had risen to about 500 birds. Since then it has
increased further. The rate of increase has been about 7% per year. Thus, the
population doubled in 10 years. Breeding success improved with grass transplantation to
stabilize nesting areas. Still, however, the population remained rather
vulnerable due to the volcanic nature of Torishima.
In 2008, ten Short-tailed Albatross chicks were moved by helicopter from
Torishima to another island, Mukojima, about 350 kilometers to the southeast in
the western Pacific Ocean.
Mukojima, in the Bonin Island group, was a site of a former
Short-tailed Albatross colony. Birds bred there until the 1920s. Mukojima is
non-volcanic.
At Torishima, 80 to 85 per cent of the world population of the Short-tailed
Albatross nest on a highly erodible slope on an outwash plain from the
caldera of an active volcano.
Monsoons send torrents of ash-laden water down the slope across the colony site.
A volcanic eruption would be catastrophic for the
birds.
During recent years, the Short-tailed Albatross has also been at a Japanese
island other than Torishima.
The bird has been on the southerly island of Minami-kojima,
one of the Senkaku Islands..
12 adult birds were found there in 1971. Breeding
was not confirmed there until 1988.
A population of 75 birds was estimated there
in 1991 (among them 15 breeding pairs). Since then, about 100 birds have been at
the island.
During late 2012, the uninhabited Senkaku Islands
were in the news due to tension between Japan and China. In Chinese, they are
the Diaoyu Islands. Translated into English,
they are the Pinnacle Islands.
They are located 200 nautical miles east of the mainland of China, 200 nautical
miles southwest of the Japanese island of Okinawa, and about 120 nautical miles
northeast of Taiwan.
The Senkaku Islands are uninhabited
by people, but they are now inhabited by birds, the rare Short-tailed
Albatrosses.
The story, told above, of the decimation of the albatrosses
at Torishima is well known. The story at the Senkaku Islands was, historically,
and unfortunately, a similar sad one, of decline and disappearance, and then,
later, recovery.
But the number of birds now at the Senkakus is not as large as at Torishima.
At the Senkakus, the albatrosses were also
slaughtered for feathers.
In 1884, it was said that "the Senkakus were so awash with albatrosses
that there was almost no room to set foot ashore".
In 1985, after victory in the Sino-Japanese War, Japan officially claimed
sovereignty over the Senkaku Islands.
That same year, the Japanese government allowed a man named Tatsushiro Koga to
"develop" the island and for he and his men to collect feathers of the
"Aho-dori",
the Short-tailed Albatross.
In 1897, they killed 160,000 of the birds, dramatically slashing the population.
In 1900, on the Senkakus, only a small number of Short-tailed
Albatrosses could be found, containing, in all, just
20 to 30 birds.
In the years that followed, with the birds gone, the business on the island
changed for a while to guano mining, and then to tuna fishing in nearby waters.
By 1940, people had left the islands, and not a single albatross
was to be found there. As late as 1963, searches there found none.
In the late 1960s, the possibility of oil and natural gas reserves under the
seabed around the Senkaku Islands was announced, and shortly after that the
issue of territorial rights for the area between Japan, China, and Taiwan began,
and, still, as of now, has continued.
But during the second half of the 20th Century, the population of the Short-tailed
Albatross has been recovering. And now it is
again a breeding bird in the Senkaku
Islands, particularly on the one island there known as Minami kojima.
Also notable on the Senkaku Islands, on Uotsuri-jima, an
endemic mammal has been found, the Senkaku Mole, Mogera
uchidai.
Regarding the history of the Short-tailed Albatross in
Japan, it should be noted that:
In 1958, the Japanese government declared the bird to be "a
special bird of protection".
In 1962, the bird became a "special national monument".
In 1993, with the ""Act for the Conservation of Endangered Species of
Wild Fauna and Flora"", the Aho-dori,
or Short-tailed Albatross
was designated by Japan as one of the "national rare species of
wild animals", and therefore always to be
protected.
Regarding the history of the Senkaku Islands, it might also be noted that:
From 1945 to 1972, the United States administered the islands before returning
them to Japanese control under the Okinawa Reversion Treaty between the US and
Japan.
In the central Pacific, at Midway Atoll (in Hawaii), 1 or 2 Short-tailed
Albatrosses were present during the last 2 decades of the 20th Century. An
incubating bird was found there in 1993, but the egg was abandoned.
More recently, in this century, a pair of Short-tailed Albatrosses came
to Midway in 2007.
In 2009, they built a nest but no egg was seen.
In November 2010, however, an egg was discovered under the presumed male of the
pair. It hatched on January 14, 2011. According to the US Fish & Wildlife
Service, the fledged youngster left the island on June 11, 2011, surviving the
tsunami which followed the Japanese earthquake of March 2011. Assumedly, that
young albatross would not return to Midway for 4 to 6 years.
That 2011 Midway fledgling represents the first time that the Short-tailed
Albatross has been known to breed outside Japanese
territory.
Back in Japan, at the Torishima breeding colony, adult birds return in October. Eggs
are laid October-November. Young are fledged from May onwards.
The following text is from "The Birds of Japan: Their Status &
Distribution", by Oliver L. Austin Jr. & Nagahisa Kuroda, published in
1953, and written when the Short-tailed (or Steller's) Albatross was thought to
be extinct:
Diomedeidae
Diomedea albatrus (Pallas)
Steller's (Short-tailed) Albatross
Japanese name: Ahodori (meaning "fool bird")
This magnificent albatross is probably extinct. Its disappearance was caused
partly by the volcanic eruptions which destroyed its former nesting grounds on
Torishima, but primarily by the activities of the plume hunters of the late 19th
and the early 20th centuries. The most-recent definite record is the one for the
few birds banded on Torishima in 1933 and killed there in 1934 (cf. Austin
1949b: 283-295).
It formerly bred on Torishima in the southern Izu Islands, on the northernmost
of the Bonin Islands, and on isolated islets in the southern Ryukyus and the
Pescadores. Its nesting season was from November through April. After the young
were on the wing, the birds moved northward along the Japanese coast to summer
in the Bering Sea, and then down the west coast of North America as far as Baja
California, before returning to their breeding grounds in late autumn. The
spring flight past Japan was marked by the numbers of dark-colored immature
birds it contained, which could be confused with the Black-footed Albatross. The
immature Steller's differed from the adult Black-footed only by its larger size
and its lighter-colored bill, neither of which could be discerned at a far
distance. An adult Steller's could also be difficult, at a distance, to tell in
the field from the adult Laysan Albatross.

The Chinese, or Swinhoe's Egret breeds on small islands off the coasts of
eastern Russia, North & South Korea, and mainland China. It formerly bred in
Taiwan and Hong Kong.
The global population of the Egretta eulophotes has been estimated to number
from 2,600 to 3,400 individuals.
A recent survey (published in 2012) of a breeding population on an offshore
island in southern China indicated a decline of 22 per cent in 6 years.
Overall, for the species, a decline of up to 20 per cent has been suspected over
10 years.
A Chinese, or Swinhoe's Egret was seen on a small island off the west coast of
Honshu during a FONT Japan Tour.
That small island, called Hegura-jima, is renowned
for its migration of birds, including vagrants, in the spring and fall.
More surprisingly, another Chinese Egret was found during that same FONT tour on
mainland Japan, at a rice paddy in western Honshu.

The total population of the Steller's Sea Eagle is estimated at about 5,000 birds and declining. Most
(more than half) of those birds winter in Hokkaido, Japan, and on the nearby
Kuril Islands.
Some birds, normally in the hundreds, winter further north on the Kamchatka
Peninsula and by the Sea of Okhotsk. Breeding is exclusively in southeastern
Siberia.
27 HOODED CRANE
Grus monarcha
Kyushu
(during FONT winter tours)
The Hooded Crane breeds in wetlands in 2 areas of central Siberia. A very few have
been known, since 1991, to breed in China.
It winters at a few localities in Japan, Korea, and eastern China.
The total population has been estimated, during recent years, from about 10,000
to 11,800 birds, having increased due to artificial feeding in the winter
(particularly at a prime wintering site, Arasaki, on the southern Japanese
island of Kyushu).
More than 80% of the world's Hooded Cranes spend the winter
at Arasaki.
In 1987, the count of Hooded Cranes at Arasaki was 6,848.
In 1992, nearly 9,000 birds were there.
On November 24, 2007, the count of Hooded Cranes at Arasaki was
10,973.
There is only 1 other
wintering locality in Japan: on the main island of Honshu, at Yashiro, with
about 100 birds there.
In Japan (& Korea), the species winters almost exclusively at feeding
stations and nearby agricultural fields.
The population of Hooded Cranes has fluctuated considerably since the 1920's. At
present, the number is probably as large as at any time since then.

of Oshima, and it has been found to be a rare winter visitor to southern
Honshu.
37 IJIMA'S (LEAF-) WARBLER (JPe)
Phylioscopus ijimae
The Ijima's Warbler breeds on the Izu Islands, southeast
of mainland Japan, between Oshima and Aogashima, where it is present from April
to September.
Migrants occur on Honshu and Kyushu, but the species has only rarely been
encountered away from its breeding area.
It has a small and fragmented population, and is
declining.
38 BONIN WHITE-EYE (or
BONIN HONEYEATER) (JPe)
Apalapteron
(formerly
Zosterops)
familare
The Bonin White-eye, or Bonin
Honeyeater is an attractive little bird restricted only to the Ogasawara
Islands, in the Pacific Ocean, offshore from Honshu, south of Tokyo.
Since it was described by an ornithologist named Kittlitz in 1831, there have
been two known subspecies, one of which is now presumed extinct, the nominate A.
f. familare. It was on the islands of Mukojima and Chichijima.
The remaining subspecies, Apalapteron familare
hahasima survives only on Haha
Island.
A bird named after Kittlitz, is one of three species of the Ogasawara Islands,
also described in the mid 1800s, that are now extinct: the Kittlitz's Thrush,
Bonin Woodpigeon, and Bonin Grosbeak.

A JAPAN TOUR IN THE SPRING FOR SOME
SPECIAL BIRDS
39 MARSH GRASSBIRD
(or
"JAPANESE MARSH WARBLER")
Megalurus p. pryeri
Honshu (during FONT spring
tours)
The Marsh Grassbird is known to breed at 6 locations on the
main Japanese island of Honshu. It probably also breeds in Heilongjiang and
Liaoning in China and at Lake Khanka in Siberia.
It is said to winter in
southern Japan, and in the Yangtze basin in China. The population in Japan is
estimated to be about 1,000 birds.
40 YELLOW
(or
"SIEBOLD'S")
BUNTING
Emberiza sulphurata
Honshu,
including Hegura Island (during FONT spring
tours)
Okinawa (during 1 FONT winter tour)
The Yellow Bunting breeds only in Japan. It is thought to
winter mainly in the Philippines, although may winter in far-southern Japan (Nansei
Shoto) and in Taiwan. It is generally uncommon in its restricted breeding range
in Japan, and it believed to have declined significantly in the 20th Century.
Species in Japan classified as NEAR-THREATENED:
41 COPPER PHEASANT (JPe)
Syrmaticus soemmerringi
Honshu (during
FONT spring & winter
tours)
Kyushu (during FONT spring & winter tours)
The Copper Pheasant is found on the Japanese islands of Honshu,
Shikoku, and Kyushu, in coniferous, broadleaved, and mixed forests. There are 6
subspecies. It was once quite common, but has declined substantially (due to,
among other things, hunting), and is now considered uncommon and difficult to
find.

43 FERRUGINOUS DUCK (also called
the FERRUGINOUS, or WHITE-EYED POCHARD)
Aythya nyroca
The range and status of the Ferruginous Duck may fluctuate
considerably from year to year, and particularly so in Asia. Thus, it can be
difficult to correctly estimate the global population or the trends for the
species.
There have marked decline of the Ferruginous Duck recently in Europe, of
more than 20 per cent in 8 countries, but the evidence of decline in the larger
Asian population is not clear.
So, the species is currently listed as being in the
"near-threatened" category. Evidence of a further, or a rapid
decline in Asia would qualify it for uplisting to "vulnerable".
The Ferruginous Duck is a vagrant in the winter in Japan.

46 WHITE-TAILED EAGLE
Haliaetus albicilla
Hokkaido (FONT
spring & winter
tours)
Honshu (during FONT winter tours)
The White-tailed Eagle occurs from Greenland &
Iceland east across Eurasia to eastern Siberia and Japan. The population has
been estimated as between 5,000 and 7,000 pairs, but the size of the Russian
population is poorly known.
In the western portion of the range, in Europe,
during the 19th Century and the first half of the 20th Century, numbers declined
dramatically.

47 ASIAN DOWITCHER
Limnodromus semipalmatus
The Asian Dowitcher is a rare breeder locally in Mongolia,
northeastern China, and nearby Russia. It is a rare migrant in
Japan.
48 BLACK WOOD PIGEON
Columba j. janthina
Honshu (on Hegura
Island) (during FONT spring tours)
Amami (during FONT spring & winter tours)
Okinawa (during FONT spring & winter tours)
The Black Wood Pigeon is an uncommon, local, and declining resident
in Japan, occurring on small islands off southern Honshu, Shikoku, and Kyushu,
and south through the Nansei Shoto islands to the Yaeyama islands. Also in
Japan, it occurs south through the Izu Islands to the Ogasawara and Iwo Islands.
Outside Japan, it occurs locally on small islands off the south coast of South
Korea (birds seen during FONT tours on Hegura Island in the Sea of Japan, in the spring,
were probably of that population).
The species inhabits dense subtropical
forest and warm temperate evergreen broadleaf forest, with a strong dependency
on mature forest. It has declined in Okinawa during and since the 1980's due to
forestry activities. The subspecies C. j. nitens (which formerly occurred on the
Ogasawara and Iwo Islands) is now thought to be extinct.

THE FOLLOWING IS PART OF A NARRATIVE RELATING TO THE
FONT TOUR IN KYUSHU, JAPAN IN JANUARY 2008,
written by Armas Hill, leader of the tour.
On the southernmost Japanese island that we visited, Kyushu,
there was the other notable species of waterfowl of our tour. Along a
particular river there, we saw, and yes - we enjoyed seeing, the Mandarin
Ducks.
Adjectives already used in this narrative, relating to waterfowl, can be used
again pertaining to the Mandarin: "brilliantly beautiful; boldly and
colorfully patterned; and exquisite".
"Mandarin", itself, is from the Sanskrit word
"mantrin", meaning "counselor".
In the mid-1500's, that word was applied to Chinese officials, as a term used by
foreigners to describe the handsomely attired senior officers of the Chinese
government.
The duck, itself, is truly of the "Far East". Its native range
is only in easternmost Asia: in not just China, but further north, breeding in
the Russian Ussurland and Kuril Islands, and in northern Japan.
The Mandarin Duck has been known as the "pearl of
Manchuria". In Russia, it's known as "Manadarinka".
It's called "Yuen Yang" in
Chinese, while in Japanese it's called "Oshidori".
In Japanese art, as early as the 8th Century, the Mandarins were
depicted, as they have been since on screen paintings, showing faithful males
and females together.
While the Japanese, or Red-crowned, Crane in Japan symbolizes
happiness and longevity, the Mandarin in Japan represents the enduring
qualities of loyalty and fidelity. The Mandarin drake and hen have been believed
to be strongly monogamous.
In China, nowadays, very few Mandarin
Ducks are to be found in the winter. But, that's not the case in southern
Japan, and particularly on Kyushu.
A few years ago I found that during the winter along the particular river,
referred to above, in southeastern Kyushu, there were a least a couple
thousand Mandarin Ducks, along the upper reaches of that river in the
wooded hills. The species was the prevalent, and, at some places, the only
species of duck along that stretch of the river. And I found that those Mandarin
Ducks were about as "wild" as ducks could be. The small groups of
ducks, along that river, would immediately fly away, as people got out of a
vehicle, on the road at a long distance from the ducks that were either swimming
on the river or tucked on and under the branches by its edge. It happened every
time, and the birds give would their distinctive calls as they flew.
These were not birds such as those in city parks. We used to visit the Mejii
Shrine in Tokyo to see the Mandarins there at a pond in
the park.
But seeing the "wilder Mandarins", in large numbers, along the
Kyushu river, has been so much more of an
experience.
Those ducks in Kyushu may come each winter from the wilder areas of mainland
Asia - in Ussurland, or from those northerly Kuril Islands. Or, maybe, they come
from northern Japan. Wherever, they come from, there are many.
A census of Mandarin Ducks wintering in Japan in 1992 tallied a total of
about 20,000 birds. The figures from that annual census in 1995 give the number
of wintering Mandarins in the Miyazaki Prefecture of Kyushu as 796 birds.
The Kyushu river we've visited for the Mandarins is in that Miyazaki
Prefecture. (A Japanese prefecture is rather like a US state.)
But the 800 or so birds just given for the entire prefecture must be a low
figure, as along that one river, during one afternoon, during one of our winter
tours in the mid-2000s, we counted at least as many as 2,000 Mandarin Ducks
- and that was without doing, in any way, what would be a proper census.
It was wonderful to see Mandarin Ducks, along that Kyushu river, again,
during our January 2008 tour!
We didn't tally as many as 2,000, but we saw quite a few. Due to some
construction along the riverside road, that would have caused us a significant
delay, we didn't go as far upriver as we normally have.

The Ryukyu Robin is endemic to the Nansei Shoto islands of southern
Japan. There are two subspecies:
E. k. komadori nests on the northern
Ryukyu Islands and winters to the southern Ryukyus.
E. k. namiyei is thought to be a
resident on Okinawa.
Some birds from the central Nansei Shoto apparently migrate as far north as
southern Kyushu, with others as far south as the Yaeyama Islands (closer to
Taiwan than to Okinawa).
