Chloropsis cochinchinensis

The blue-winged leafbird (Chloropsis cochinchinensis) is a species of leafbird found in forest and second growth throughout Southeast Asia as far east as Borneo and as far south as Java. It previously included Jerdon's leafbird (C. jerdoni) from the Indian Subcontinent, and the Bornean leafbird (C. kinabaluensis) 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 distribution of the blue-winged and the Bornean leafbird are known to approach each other, but there is no evidence of intergradation.
