Cardinal à ventre blanc Caryothraustes poliogaster

Rather chunky, social bird of humid evergreen forest and edge in tropical lowlands and foothills. Usually in small and often noisy groups (at times up to 50 birds), moving at middle to upper levels in fruiting trees; not usually with mixed-species feeding flocks. Sexes look alike, with subtly attractive plumage: mustard-yellow head and breast with black face and blue-gray belly. Calls are buzzy splutters and whistles.
