the tone and intensity of the brown color both on the upper and under 
surface, and also in the uniform or mottled color on the breast. The 
coloration of the throat is very different in individuals, being in some 
almost uniform brown, succeeded by a jugular spot of white. 
“Young (Peking, Sept. 1868, R. Swinhoe).—Ashy brown, mottled 
with whitish streaks and terminal spots to the feathers, the greater 
coverts edged and tipped with buffy white, the rest of the coverts 
spotted with whitish at the tips like the back; primary-coverts and quills 
dark brown, the inner secondaries edged and tipped with pale rufous; 
under surface very thickly mottled with brown, the feathers being white 
with dusky brown edges.” (Sharpe.) 
The Siberian flycatcher must be considered a rare winter visitant to 
the Philippine Islands.

In the gray-spotted flycatcher there is some variation in the brown 
streaks of the under parts, but this species is not easily mistaken for any 
other bird except Piprisoma @ruginosum which has a very differently 
shaped bill. The gray-spotted flycatcher is one of the commonest winter 
visitants and is found in small numbers throughout the islands.
