Spectacled Tetraka

Small and stub-tailed, appearing mostly dark. Shows vivid electric-blue speckling on chest, back, and head, brilliant blue in direct light. Shocking pure white rump and upper tail are diagnostic and obvious. Reliant on primary forest. Voice includes a drawn-out mournful whistle, similar to a squeaky bike wheel.

A streak-breasted oriole with a rather long, lipstick-pink bill. Male is yellow with a glossy black hood and dark wings. Female is olive-green above. Both sexes have dark red eyes. On Borneo absent from the northern parts of the island, where replaced by the very similar Ventriloquial Oriole. Inhabits lowland and hill forests and forest edges, typically moving in the upper levels of the forest. Sometimes found singly, sometimes in pairs or mixed flocks. Song is short but fluidly melodic, often with the last note stretched out. Gives a harsh, jay-like “chew!”.

Large, stocky tanager. Males are red with dusty wash on upperparts and sides (especially on northern populations); females are muted yellowish. Both sexes are brightest on the throat and crown. Also note stout bill and dark lores. Several separate populations occur from the southwestern U.S. to South America, probably comprising multiple different species. Northern birds prefer mountainous areas with mixed pine-oak forest. South American birds found in a variety of forested habitats, from open woodlands in the lowlands to scrubby areas in the high Andes. Most similar to Summer Tanager, but grayer tones to plumage and usually different habitat. Song is sweet like American Robin: mostly clear phrases with some hoarser notes.
