White-throated Rock Thrush, Monticola gularis,
during FONT tour on Hegura Island, Japan, May 21, 2005.

This species is quite a rarity in Japan. It is normally on mainland Asia, 
breeding mostly in Manchuria and eastern Siberia, and wintering in southern China, and further south in Southeast Asia.  
Note in this photo the white patch on the throat.
