European honey buzzard
The European honey buzzard (Pernis apivorus), also known as the pern or common pern, is a bird of prey in the family Accipitridae.
Etymology
Despite its English name, this species is more closely related to kites of the genera Leptodon and Chondrohierax than to true buzzards in Buteo. The binomen is due to Linné, derived from περνης, an Aristotelian term for a bird of prey, and Latin apivorus "bee-eating" (although bees are much less important than wasps in the bird's diet).
Description
The 52–60-centimetre-long (20–24 in) honey buzzard is larger and longer winged, with a 135–150-centimetre (53–59 in) wingspan, when compared to the smaller common buzzard (Buteo buteo). It appears longer necked with a small head, and soars on flat wings. It has a longer tail, which has fewer bars than the Buteo buzzard, usually with two narrow dark bars and a broad dark sub-terminal bar. The sexes can be distinguished on plumage, which is unusual for a large bird of prey. The male has a blue-grey head, while the female's head is brown. The female is slightly larger and darker than the male.
