Bright-rumped Yellow-Finch

A sparrow-like weaver. Red-hooded breeding males are distinctive, but females and non-breeding males are drab. A Comoros endemic that is found in and adjacent to humid forest on the western three islands, and in drier, scrubby lowland habitats on Mayotte. Plumage varies across the different islands. The most distinctive birds, on Grand Comoro, have much less red on the breast than other populations. Can be very similar to Red Fody. Breeding male Red-headed Fody lacks red on the back and belly, though molting male Red Fody can match this pattern. Females and non-breeding males very similar to Red Fody, but Red-headed Fody is larger, darker, and more greenish, with a longer, slightly curved bill. Also similar to female House Sparrow, but distinguished by the more olive-green coloration and the longer bill. Calls are high, silvery notes, given in long series as a song. 

Greenish and golden tanager of low, dense understory and midstory of humid montane forest just below treeline in the central and Northern Bolivian Andes, including adjacent extreme SE Peru. Distinguished from other hemispinguses by rich orange-gold supercilium and throat. Travels in pairs in mixed species flocks, generally within two meters of the ground. Song a very high, long, uneven twittering,

Large, terrestrial bird of lowland forest; unlike anything else in range. Appears all dark with paler belly; note long tail, heavy bill, and bare red skin around eye. Uncommon and shy; usually seen alone, on or near the ground, fleeing swiftly on foot at the slightest disturbance. Follows army ant swarms and herds of peccaries to prey on insects and small vertebrates flushed by the animals’ activities. Frequently snaps bill in alarm or while foraging. Far-carrying song is a single, gruff hoot, somewhat recalling Zigzag Heron, repeated at long intervals.
