Common buzzard – Buteo buteo
is a medium-to-large bird of prey whose range covers most of Europe and extends into Asia. Over much of its range, it is resident year-round, but birds from the colder parts of the northern hemisphere typically migrate south (some well into the southern hemisphere) for the northern winter. The common buzzard measures between 40 and 58 cm (16 and 23 in) in length with a 109–136 cm (43–54 in) wingspan and a body mass of 427–1,364 g (0.941–3.007 lb), making it a medium-sized raptor. The common buzzard breeds in woodlands, usually on the fringes, but favours hunting over open land. It eats mainly small mammals, and will come to carrion. A great opportunist, it adapts well to a varied diet of pheasant, rabbit, other small mammals to medium mammals, snakes and lizards, and can often be seen walking over recently ploughed fields looking for worms and insects.[citation needed] The steppe buzzard, B. (b.) vulpinus breeds from east Europe[where?] eastward to the Far East, excluding Japan. It is a long-distance migrant, excepting some north Himalayan birds, and winters in Africa, India and southeastern Asia. In the open country favoured on the wintering grounds, steppe buzzards are often seen perched on roadside telephone poles.
