Jerdon's baza (Aviceda jerdoni) is a species of bird of prey of the family Accipitridae, and native to Southeast Asia. It is named for British surgeon and naturalist Thomas C. Jerdon.

Description

Jerdon's baza is a medium-sized raptor, 16.9 to 18.7 inches in length, a wingspan of 42.8 to 46.2 inches, and a body weight of 12.4 ounces. Females are slightly larger than males. Coloration varies slightly among the subspecies, but generally it is brown above, with banded wings and tail, and whitish below, with tan horizontal bands. The head it light cream to white, and capped by a long, black erectile crest. In flight - and especially with juvenile birds - it can be confused with the crested goshawk (Accipiter trivirgatus), the Oriental honey-buzzard (Pernis ptilorhynchus), or the changeable hawk-eagle (Nisaetus cirrhatus).

The call is described as kip kip kip or tchip TCHEP, and usually made while in display flights.

Threats

The ICUN has this species classified as "least concern", in part due to its extremely large range. However, study of this bird is incomplete, and confusion with other species, fragmentary population, and unobtrusive behavior may cause it to be overlooked. It is known to suffer habitat loss due to deforestation.
