The Common Buzzard (Buteo buteo) is a medium to large bird of prey, whose range covers most of Europe and extends into Asia. It is typically between 5157 cm in length with a 110 to 150 cm (1 metre to a metre and half) (4860 inch) wingspan, making it a medium-sized raptor. There are around 40,000 breeding pairs in Britain. It is usually resident all year, except in the coldest parts of its range, and in the case of one subspecies.

It 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. The birds have incredible strength and are therefore able to pick up food of all weights.

Buzzards do not normally form flocks, but several may be seen together on migration or in good habitat. The Victorian writer on Dartmoor, William Crossing, noted he had on occasions seen flocks of 15 or more at some places. Though a rare occurrence, as many as 20 Buzzards can been spotted in one field area, approximately 30 metres apart, so cannot be classed as a flock in the general term, consisting of those males (and females) without a mate or territory. They are fiercely territorial, and, though rare, fights do break out if one strays on another pair's territory, but dominant displays of aggression will normally see off the interloper. Pairs mate for life. To attract a mate (or impress his existing mate) the male performs a ritual aerial display before the beginning of spring. This spectacular display is known as 'the roller coaster'. He will rise high up in the sky, to turn and plummet downward, in a spiral, twisting and turning as he comes down. He then rises immediately upward to repeat the exercise.

This broad-winged raptor has a wide variety of plumages, and in Europe can be confused with the similar Rough-legged Buzzard (Buteo lagopus) and the only distantly related Honey Buzzard (Pernis apivorus), which mimics the Common Buzzard's plumage for a degree of protection from Northern Goshawks. The plumage can vary in Britain from almost pure white to black, but is usually shades of brown, with a pale 'necklace' of feathers.

Hoi Marcel,
Echt super deze actiefoto. Je moet ook maar geluk hebben. Misschien zou ik zelf iets meer van de voorgrond hebben weggelaten.
Ik neem aan dat er nog wel iets van vlees tussen het gras zit, want volgens mij zijn deze vogels niet vegetarisch.
