Western Bristlebird

Nest parasite that lays its eggs in the nests of Peters’s Twinspot. Breeding males are glossy greenish-black, and in good light may show a paler gray wash across the head and breast. Females and non-breeding males are streaky and brown on the back, with a bold facial pattern and pale underparts with gray across the breast. The bill is whitish and the legs pale red. Found along forest edge, and in cultivation and moist woodland. The song is a fast mix of scolding and squeaky notes, often mixed with imitations of the vocalizations of its host twinspot: a fast, silvery trill. Similar to other indigobirds, but breeding male separated by its greenish gloss and all-black wings. Non-breeding male and female can be tentatively identified by the gray wash across the breast.

Small hummingbird of the Andes from southern Bolivia through Argentina into central Chile; found in rocky and shrubby valleys, villages, and any open or semiopen areas with flowers. Often builds nest under eaves of buildings or bridges: a bulky cup of plant material and wool to insulate against cold nights. Fairly common. Readily identified in most of range by extensively white tail. Male has an emerald green gorget and a broad blue-black stripe on belly. Female is rather drab, but note slightly decurved bill, spotted throat, and tail pattern.

A dark pigeon that is endemic to the Abyssinian highlands. There is a white mark on the back of the head, and white patches in the wings that are conspicuous in flight. Found at middle and high elevations. Nests in rocky areas as well as in towns and cities, and feeds mainly in grassland and cultivated areas. Can be similar to the highly variable feral Rock Pigeon, but distinguished by the white mark on the head. Not very vocal, but does sometimes give a low cooing call.
