White-cheeked Tern
Sterna repressa
Sub-tropical tern; slightly smaller than Common Tern with a lighter and less powerful flight, as well as a longer-billed and shorter-legged profile. In all plumages, note the darker upperparts, including the rump and uppertail. Adults have medium dark gray underparts with a dark underwing trailing edge, similar to the shorter-tailed Whiskered Tern. Note that in different light conditions, Common Tern also shows gray underparts, but Common Tern always has a white tail and rump. Young birds are very similar to Common Tern, but White-cheeked Terns are more strongly marked. Breeds on small islands and coral reefs. Vocalisations similar to Common Tern.

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.

Montserrat Oriole
Icterus oberi
A slim species of mountain forests where it feeds on insects at middle elevation. Males have a black head, chest, and back that contrast with a yellow belly and rump. Females are dull yellow-green above and dingy yellow below. Montserrat Orioles are larger than warblers, vireos, and tanagers and they have a long, relatively thick-based and sharply tipped bill. No similar species occur within its range. Vocalizations include loud whistles and harsh chrrrr-like calls.

Temminck's Tragopan
Tragopan temminckii
Rotund terrestrial bird of hilly forests, usually seen singly. Male exquisitely colored: bright flame-orange overall, with white dots all over the body, black face, and electric blue facial wattle that is inflated into a liver-shaped, dazzling red-and-blue flap during courtship. Female similarly shaped and sized, dark brown overall, with pale spotting and streaking. Generally quiet; courting males give loud booming moans.
