Black Oriole

Oriolus hosii

Unique dark oriole with a restricted range: found only in montane and submontane forests in northwestern Borneo, primarily within the Paya Maga highlands of Sarawak state. Male is inky black all over with a slight blue gloss. Female has a gray belly. Both sexes have a bright red bill and dark rust-red vent. Forages quietly in the canopy, often alone, but sometimes in pairs or small groups. Short echoing song can be likened to “woo-wich’ew!”.

Identification

The black oriole (Oriolus hosii) is a species of bird in the family Oriolidae. It is endemic to the island of Borneo. One of the least known of the orioles, its distribution range is restricted to Sarawak in Borneo. Along with the black-and-crimson, maroon, and silver orioles, it belongs to a clade of red and black orioles. The binomial name is after Charles Hose who collected the first specimen of the species on Mount Dulit. Its natural habitat is subtropical or tropical moist montane forests where it is threatened by habitat loss.

Himalayan White-browed Rosefinch

Himalayan White-browed Rosefinch

Carpodacus thura

Medium-sized rosefinch of semi-open and brushy habitats. Male is beautiful, with a streaked rich brown back and lilac-pink cheeks, brow stripe, and underparts; note namesake bright white patch at the rear of the brow stripe. Female is streaky brown above and streaky off-white below, with a rusty breast patch. Very similar to Chinese White-browed Rosefinch, but range overlap is minimal; see that species’ account. Often gives a hoarse and nasal series of ascending notes: “beet-beet-beET-bEEt-bEEt!”

Blackish Nightjar

Blackish Nightjar

Nyctipolus nigrescens

A fairly small, dark nightjar found in the lowlands and foothills of northern South America. Intricately patterned with dark browns and grays; lacks any obvious features like a collar (although it sometimes shows a small white patch on the side of the neck). Males have small white corners on the tail. Almost always found at a landslide or rocky slope at the forest edge or in clearings, singly or in pairs. Most often detected at dawn and dusk, when it gives a burry “peer!” song and “pip” calls.

Green-headed Oriole

Green-headed Oriole

Oriolus chlorocephalus

Old World oriole with mostly yellow plumage, a dull-green hood, and a red bill. Found in forest, forest edge, lush woodland, and adjacent secondary habitats, at low and middle elevations. Song is a series of slurred, liquid whistles, and calls include a raspy, up-slurred whine. Similar to African Black-headed Oriole, but with a good view, easily separated by the green rather than black hood. Often found in the same areas as Eurasian Golden and African Golden Orioles, but distinguished by being hooded rather than yellow-headed.
