The Bornean bristlehead, also variously known as the bristled shrike, bald-headed crow or the bald-headed wood-shrike, is the only member of the passerine family Pityriasidae and genus Pityriasis. It is an enigmatic and uncommon species of the rainforest canopy of the island of Borneo, to which it is endemic.
The Mantanani scops owl, is a small owl in the scops-owl genus Otus found on small islands between Borneo and the Philippines. It is listed by the IUCN as "near threatened" because its range is limited with its population being fragmented on several different islands, and its forest habitat is being degraded by ongoing logging and clearance.
The chestnut-necklaced partridge is a species of bird in the family Phasianidae. It is found in forests in the Malay Peninsula and Sumatra. It is threatened by habitat loss and trapping. The International Union for Conservation of Nature (IUCN) has assessed it as vulnerable.
The red-breasted partridge, also known as the Bornean hill-partridge, is a species of bird in the family Phasianidae. It is endemic to hill and montane forest in Borneo, preferring bamboos and thickets. The International Union for Conservation of Nature (IUCN) has assessed it as a least-concern species.
The long-billed partridge is a species of bird in the family Phasianidae.
Rhizothera is a bird genus in the family Phasianidae, native to Malaysia and Indonesia. They are the only genus in the tribe Rhizotherini. Established by George Robert Gray in 1841, it contains the following species:
The Bornean stubtail is a species of bird in the cettiid warbler family Cettiidae. It is endemic to the island of Borneo, where it inhabits forest floors and undergrowth in montane forests at elevations of 750–3,150 m (2,460–10,330 ft). It is a small, short-tailed warbler, measuring 9.5–10 cm (3.7–3.9 in) in length and having an average mass of 10.4 g (0.37 oz). The tops of the head and the upperparts are brown, with whitish underparts that turn grey at the sides of the breast and the flanks. The supercilium is long and buffish-brown, with an equally long dark grey eyestripe and a thin yellow eye-ring. Both sexes are similar.
The Dulit frogmouth is a little-known species of bird in the frogmouth family, Podargidae, with a patchily recorded distribution in the mountain forests of northern and central Borneo to which it is endemic. The species is monotypic.
The Bornean frogmouth is bird species in the family Podargidae. Some taxonomists consider it to be a subspecies of the short-tailed frogmouth, but others consider it to be a distinct species. It is found in Indonesia and Malaysia and is endemic to the island of Borneo. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest. It is threatened by habitat loss.
The mountain blackeye, sometimes referred to as the olive blackeye or simply black-eye, is a species of passerine bird in the family Zosteropidae. It is endemic to the highest mountains on the island of Borneo. It is known from both Malaysian states on the island, and four of the five Indonesian provinces, but has never been recorded in Brunei. Typically found at elevations above 1,800 m (5,900 ft), the mountain blackeye sometimes moves to lower altitudes during periods of drought. There are four subspecies, which show clinal variations in size and coloring. Birds in the north are largest, darkest, and proportionately longer-tailed, while those further south are smaller, paler, and proportionately shorter-tailed. Adults are dark olive-green with a sharply-pointed, bright yellow-orange bill and a small dark mask connecting black lores with a black eye-ring. The subspecies show varying amounts of yellow in their plumage, particularly on the face and underparts. Young birds resemble their parents, but have less brightly colored bills.
The black-sided flowerpecker, also known as the Bornean flowerpecker, is a species of bird in the family Dicaeidae. It is endemic to the island of Borneo, where it is found in the mountains, primarily above 1,000 m (3,300 ft) in elevation. The species is sexually dimorphic. The male has glossy blue-black upperparts, with a scarlet throat and breast, a dark grey upper belly, olive flanks, a white lower belly, and a buffy vent and undertail coverts. The female is olive-green above and greyish below, with buffy flanks and a whitish throat. It inhabits a range of forest habitats, including primary and secondary montane forest, kerangas forest, and scrub, and is also occasionally found in gardens. It feeds primarily on small fruits—particularly mistletoe berries—as well as seeds, nectar, and various invertebrates. It builds a nest of moss, camouflaged on the outside with lichens and lined with the pith of tree ferns. The International Union for Conservation of Nature rates it as a species of least concern. Though its numbers have not been quantified, the black-sided flowerpecker is said to be common throughout much of its range, and any declines are not thought to be precipitous. However, destruction of forest for palm plantations may impact it.
The black oriole 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.
The blue-headed pitta is a species of bird in the pitta family Pittidae. It is endemic to Borneo.
Whitehead's trogon is a species of bird in the family Trogonidae. It is endemic to the island of Borneo, where it is an uncommon resident in primary mountain forest. One of Borneo's largest trogons at 29 to 33 cm long, it is sexually dimorphic. The male is crimson on the head, nape, and underparts, with a black throat and grey chest; the rest of his upperparts are cinnamon-coloured. The female is similarly patterned, but cinnamon-brown where the male is scarlet. The species was first described for science by Richard Bowdler Sharpe in 1888, who named it for British explorer and collector John Whitehead. There are no subspecies.
The Borneo black-banded squirrel is a species of rodent in the family Sciuridae. It is endemic to northern Borneo.
The Borneo thrush, also known as the mountain blackbird or locally in Dusun as Luhui tana, is a bird in the thrush family. It is a subspecies of the island thrush endemic to the island of Borneo.
