Blue-winged Leafbird

The blue-winged leafbird is a leafbird of forest and second growth throughout South-east Asia as far east as Borneo and as far south as southern Sumatra. The male is green-bodied with a yellow-tinged head, a black face and throat and a blue moustachial line. The female has a greener head and a blue throat, and young birds resemble the female without the blue throat patch. (Wikipedia, general species account)

It was previously treated as including Jerdon's and the Bornean leafbirds as subspecies, but it differs in measurements and morphology, and the Javan leafbird has also been split. The superficially similar golden-fronted leafbird lacks blue in the flight feathers and tail and has a golden forehead. As in other leafbirds, its call is a rich mixture of imitations of other birds.
