Red-tailed Greenbul
Criniger calurus
A medium-sized greenbul often found in flocks in forest and forest edge with other bearded-greenbuls. Like all bearded-greenbuls, will sometimes puff out its throat feathers. Often forages actively in the foliage. Shows a grayish head, a bright white throat, yellow-green underparts, and olive-green upperparts with a reddish tail. Nearly identical to White-bearded Greenbul, and can occur with it in the same mixed-species flocks in Central Africa. Not all individuals can be safely identified. Listen for Red-tailed Greenbul’s distinctive calls as they forage in the branches and leaves, and look for its brighter tail and, at close range, its bigger, wider bill. The species is vocal, frequently giving a “hup-chup-cheer-you-up!” or similar multi-parted variations.

Checker-throated Stipplethroat
Epinecrophylla fulviventris
This antwren is tiny, round, and short-tailed. There are no bright colors, just a mix of buffy underparts and grayer-brown upperparts. Look for the male’s distinctive black-and-white spotting on throat. Female lacks this feature, but note her dark wing with buffy spots. Both sexes have a pale eye. Found in pairs or small flocks, usually in the lower levels of forests. Often joins larger mixed-species flocks.
Brown-throated Wattle-eye
Platysteira cyanea
Small black-and-white bird with a bright red patch of bare skin above the eye. Males have a black breast band, and females a brown throat. Found in thick woodland, gallery forest, and mangroves. The song is usually given as a duet: a descending series of melancholy whistles from the male, and lower rasping notes from the female. Similar to Black-throated Wattle-eye, but shows a white slash on the wing, and the female has a brown rather than white throat. Separated from batises by the red wattle and, in females, by the brown throat.
White-tailed Shrike-Tyrant
Agriornis albicauda
Scarce and local in open and semiopen habitats of the high Andes, where it usually greatly outnumbered by similar Black-billed Shrike-Tyrant. Both species have mostly white tail (obvious in flight) and are best separated by bill size: White-tailed Shrike-Tyrant has a stout bill that is pale below compared with the slender, dark bill of Black-billed Shrike-Tyrant. These species can occur side-by-side and have similar habits, perching on prominent lookouts but then disappearing easily; both run well on the ground and often fly long distances.
