thumb|Leafbird
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.
Taxonomy
The genus Chloropsis was introduced in 1827 by the English naturalists William Jardine and Prideaux Selby with the type species as Turdus cochinchinensis Latham, the Javan leafbird. The genus name is from the Ancient Greek χλωρος/khlōros meaning "green" and οψις/opsis meaning "appearance". The genus was formerly placed with the fairy-bluebirds in the family Irenidae
A large molecular phylogenetic study of the passerines published in 2019 found that the family Chloropseidae was sister to the family Irenidae containing the fairy-bluebirds.
Description
The leafbirds range in size from , and in weight from . They resemble bulbuls, but whereas that group tends to be drab in colour, leafbirds are brightly plumaged, with the predominant green over the body giving rise to their common name. The family is mostly sexually dimorphic in their plumage, this can vary from the highly dimorphic orange-bellied leafbird to the Philippine leafbird, which exhibits no sexual dimorphism. Most of the differences between the sexes are in the extent of the other colours in the plumage, particularly in the colours around the head and the blue or black face mask, with females having less colour and a less extensive (or absent) mask.
Like bulbuls, leafbirds drop many body feathers when they are handled. This may confuse predators, especially snakes.||Borneo and southern Sumatra
