The Bornean leafbird (Chloropsis kinabaluensis), 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[1] (elevated areas, including the Meratus Mountains). It has traditionally been considered a subspecies of the blue-winged leafbird (C. cochinchinensis), 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.
