The blue-winged leafbird is a species of leafbird found in forest and second growth throughout Southeast Asia as far east as Borneo and as far south as southern Sumatra. It previously included Jerdon's leafbird from the Indian Subcontinent, and the Bornean leafbird from northern Borneo as subspecies, but differs from both in measurements and morphology, with Jerdon's lacking any blue to the flight feathers, and Bornean having a distinctive male-like female plumage. The Javan leafbird, which is endemic to Java, was also formerly grouped with the species, but more recent phylogenetic studies have split both. The distribution of the blue-winged and the Bornean leafbird are known to approach each other, but there is no evidence of intergradation.
The golden-fronted leafbird is a species of leafbird. It is found from the Indian subcontinent and south-western China, to south-east Asia and Sumatra.
The Bornean peacock-pheasant is a medium-sized pheasant. It is probably the rarest and certainly the least known of all peacock-pheasants. This elusive bird is endemic to lowland forests of Borneo.
Jerdon's leafbird is a species of leafbird found in forest and woodland in India and Sri Lanka. Its name honours Thomas C. Jerdon.

The red-breasted partridge, also known as the Bornean hill-partridge, is a species of bird in the family Phasianidae.

The mountain serpent eagle, also known as the Kinabalu serpent eagle, is a bird of prey that is found in northern Borneo. It is found at altitudes of 1,000–4,100 metres (3,300–13,500 ft) in forest, especially where it becomes stunted. Where their range overlaps, the crested serpent eagle generally occurs at lower altitudes. The mountain serpent eagle is darker than the Bornean subspecies of the crested serpent eagle.
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 Sumatran leafbird is a species of bird in the family Chloropseidae. It is endemic to forest and plantations in Sumatra in Indonesia. It has often been included as a subspecies of the golden-fronted leafbird, but the two differ extensively in, among others, morphology, with the male of the Sumatran leafbird having a yellow forehead, and the female resembling a female blue-winged leafbird, but with a yellowish forecrown and no blue to the wings and tail.
The yellow-throated leafbird is a species of bird in the family Chloropseidae. It is endemic to the Palawan in the Philippines.
The greater green leafbird is a species of bird in the family Chloropseidae. It is distinguished from the lesser green leafbird by its powerful beak, yellow throat and eye ring of the female; and lack of a yellow border along the black throat patch found in the male C. cyanopogan.
The blue-masked leafbird is a species of bird in the family Chloropseidae. It is endemic to humid montane forest in the western regions of the Indonesian island of Sumatra. Generally, it lives in areas from 600 to 1,500 m in elevation. It is the smallest species of leafbird.
The Bornean blue flycatcher is a species of bird in the family Muscicapidae. It is found in Brunei, Indonesia, and Malaysia, where it is endemic to the island of Borneo. Its natural habitat is subtropical or tropical moist montane forests.
The Bornean whistler or Bornean mountain whistler, is a species of bird in the family Pachycephalidae. It is endemic to the island of Borneo.
The Bornean wren-babbler is a species of bird in the family Pellorneidae. It is found in Brunei, Indonesia, and Malaysia, where it is endemic to the island of Borneo. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical swampland. It is threatened by habitat loss.
The Bornean barbet is a species of bird in the Megalaimidae family. It is found in Indonesia and Malaysia where it is endemic to the island of Borneo. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests.
The Bornean treepie is a passerine bird belonging to the treepies genus, Dendrocitta, of in the crow family, Corvidae. It is endemic to the island of Borneo. It is sometimes treated as a subspecies of the Sumatran treepie.
The Bornean bulbul is a member of the bulbul family of passerine birds. It is endemic to the island of Borneo.
The Bornean banded pitta is a species of bird in the family Pittidae. It is found only in Borneo. It was formerly considered conspecific with the Javan and Malayan banded pittas. Together, they were referenced as the banded pitta.
The Javan leafbird is a species of leafbird found in forest and second growth in Java. The Javan leafbird was formerly grouped with the blue-winged leafbird, but more recent phylogenetic studies have split both. The distribution of the blue-winged and the Bornean leafbird are known to approach each other, but there is no evidence of intergradation.
