Appearance
Despite its name, this species is not related to "Buteo" buzzards, and is taxonomically closer to the kites.It appears long-necked with a small head, and soars on flat wings. The head lacks a strong superciliary ridge, giving it a facial appearance very unlike a raptor. It has a long tail and a short head crest. It is brown above, but not as dark as European honey buzzard, and paler below. A dark throat stripe is present. Unusually for a large bird of prey, the sexes can be distinguished. The male has a blue-grey head, while the female's head is brown. She is slightly larger and darker than the male. The male has a black tail with a white band.
It breeds in Asia from central Siberia east to Japan. It is a summer migrant to Siberia, wintering in tropical Southeast Asia. Elsewhere, it is more-or-less resident. It is a specialist feeder, living mainly on the larvae of social bees and wasps, and eating bits of comb and honey; it takes other small insect prey such as cicadas.
The crested honey buzzard breeds in woodland, and is inconspicuous except in the spring, when the mating display includes wing-clapping. The display of roller-coasting in flight and fluttering wings at the peak of the ascent are characteristic of the genus "Pernis".
It is larger and longer-winged than its western counterpart, the European honey buzzard, "Pernis apivorus".
