Sao Tome Oriole

Oriolus crassirostris

Old World oriole that is unusual in nearly lacking yellow in its plumage. There is a dark hood which is solid in males and streaky in females. A small white mark on the wing and pale yellow marks in the outer tail can be conspicuous in flight. Found in the canopy of rainforest at low and middle elevations. Song is a series of slurred, low-pitched liquid whistles. Calls include a harsh, upslurred nasal scold. Easily identified, as it is the only oriole on the island of Sao Tome.

Bob-tailed Weaver

Bob-tailed Weaver

Brachycope anomala

A small odd finch-like weaver with a short stubby tail. Breeding male has a yellowish crown and breast and a black face mask. Non-breeding male, female, and juvenile are buffy with blackish edging to the upperparts. A locally common resident in clearings near large rivers within the forested Congo Basin, where populations are scattered. Found in pairs and small groups. Vocalizations are quite simple: repeatedly gives a harsh “djet,” and the song has some liquid notes. Non-breeding male and female could be confused with many other small dull birds, but the short tail is unique. 

Abyssinian Longclaw

Abyssinian Longclaw

Macronyx flavicollis

A large and relatively colorful member of the pipit family. Note the black necklace, orange throat, and partially yellow eye-stripe. The white corners of the black tail are conspicuous during the weak, fluttering flight. Found on the ground in montane grassland, often in wet areas. Brownish immatures can be confused with pipits, but are larger and more robust. The vocalizations include “tsik” calls and whistles. 

Yellow Flycatcher

Yellow Flycatcher

Erythrocercus holochlorus

A small and colorful flycatcher with olive-yellow upperparts and yellow underparts. Found in lowland forest, mostly in the canopy. Often joins mixed-species flocks. Somewhat similar to yellow-warblers, but much smaller and found in different habitats. Similar to Livingstone’s Flycatcher, but there is very little overlap in range, and can easily be separated by the olive-green rather than rufous tail. Vocalizes frequently, giving high-pitched, chittering calls and a quick whistled song.
