European honey buzzard, Pernis apivorus, Bivråk
The 52–60-centimetre (20–24 in)-long 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 subterminal 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.
