The jungle babblers, Pellorneidae, are mostly Old World passerine birds belonging to the superfamily Sylvioidea. They are quite diverse in size and coloration, and usually characterised by soft, fluffy plumage and a tail on average the length of their body, or longer. These birds are found in tropical zones, with the greatest biodiversity in Southeast Asia and the Indian subcontinent.
Morphological diversity is rather high; most species resemble warblers, jays or thrushes, making field identification difficult.
The family Pellorneidae was first introduced by the French-American ornithologist Jean Théodore Delacour in 1946. Pellorneidae used to be one of four subfamilies of Timaliidae (tree- and scimitar-babblers), but was then elevated to its own family rank in 2011 based on molecular markers.
Pellorneidae are found throughout the tropics of Asia and Africa. Preferring sheltered places, these birds tend to stick to the undergrowth or forest edge.
