The three fairy-bluebirds are small passerine bird species found in forests and plantations in tropical southern Asia and the Philippines. They are the sole members of the genus Irena and family Irenidae, and are related to the ioras and leafbirds.
The leafbirds (Chloropseidae) are a family of small passerine bird species found in the Indian Subcontinent and Southeast Asia. They were formerly grouped with the ioras and fairy-bluebirds in the family Irenidae. As presently defined, the leafbird family is monogeneric, with all species placed in the genus Chloropsis. A large molecular phylogenetic study published in 2019 found that the family Chloropseidae is sister to the family Irenidae containing the fairy-bluebirds.
The ioras are a small family, Aegithinidae, of four passerine bird species found in south and southeast Asia. The family is composed of a single genus, Aegithina. They were formerly grouped with the leafbirds and fairy-bluebirds, in the family Irenidae.
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 olive-backed sunbird, also known as the yellow-bellied sunbird, is a species of sunbird found from Southern Asia to Australia.
The orange-bellied leafbird is a bird native to the central and eastern Himalayas, Yunnan and northern parts of Southeast Asia. The greyish-crowned leafbird, which is found in Hainan, is again considered conspecific. The scientific name commemorates the English naturalist Thomas Hardwicke.
Jerdon's leafbird is a species of leafbird found in forest and woodland in India and Sri Lanka. Its name honours Thomas C. Jerdon. It has traditionally been considered a subspecies of the blue-winged leafbird, but differ in measurements and morphology, it lacking the blue flight feathers for which the blue-winged leafbird was named.
The lesser green leafbird is a species of bird in the family Chloropseidae. It is found in Brunei, Indonesia, Malaysia, Myanmar, Singapore, and Thailand. Its natural habitat is subtropical or tropical moist lowland forest. It is threatened by habitat loss.
The Philippine leafbird is a species of bird in the family Chloropseidae. It is endemic to the Philippines. It is found in the islands of Mindanao, Leyte, and Cebu.
The Bornean leafbird, also known as the Kinabalu leafbird, is a species of bird in the family Chloropseidae. It is found in humid forest in Borneo, to which it is endemic. It has traditionally been considered a subspecies of the blue-winged leafbird, but differ in measurements and morphology, the female Bornean leafbird having a distinctive male-like plumage. The distribution of the two are known to approach each other, but there is no evidence of intergradation.
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 scarlet-backed flowerpecker is a species of passerine bird in the flowerpecker family Dicaeidae. Sexually dimorphic, the male has navy blue upperparts with a bright red streak down its back from its crown to its tail coverts, while the female and juvenile are predominantly olive green. It is found in subtropical or tropical moist lowland forests and occasionally gardens in a number of countries throughout South and East Asia.
The Javan leafbird is a species of leafbird found in forest and second growth in Java. It was formerly considered as conspecific with the widespread blue-winged leafbird.
