Sao Tome Thrush

Medium-sized sunbird in which males have an iridescent green head and breast, and females a green helmet. Depending on the light, these green areas can sometimes look blue. The pale yellow shoulder tufts are usually hidden. Found at low and middle elevations in lush woodland, gardens, and forest. Often in pairs, and sometimes in mixed-species flocks. Vocalizations include mewing and scolding calls, and a song that starts with hesitant notes but then breaks into a long trill. Male similar to male Blue-throated Brown Sunbird, but paler overall, with a larger area of iridescent green rather than blue on the head.

A rotund, short-legged ground-dwelling dove that usually runs rather than flies when startled. Mostly brown with a pale whitish-gray chest and face. With good views, the pale cinnamon neck and head are distinctive. No similar species occur in its range. Gives a typical dove-like “whoo whoo” call that accelerates over around 15 notes.

A typical house-martin, with dark upperparts, white underparts, a white rump, and a rather dumpy body. Differs from Common and Asian House-Martins by its sooty throat. Upperparts can have a bluish gloss if seen in good light. Breeds on ridges and cliffs, and occasionally around human settlements. Associates with other swallows and swifts, often gathering over water to catch emerging insects.
