The common buzzard (Buteo buteo) [2] is a medium-to-large bird of prey which has a large range. It is a member of the genus Buteo [2] in the family Accipitridae. [2] The species lives in most of Europe and extends its breeding range across much of the Palearctic as far as northwestern China (), far western Siberia and northwestern Mongolia.
The grasshopper buzzard is quite sociable and is often seen in groups of 50 to 100 birds, most frequently in recently burnt areas where there are insect emergences. [4] Grasshopper buzzards are specialists in catching grasshoppers during the non-breeding season; when breeding they consume a range of insects, mostly grasshoppers and beetles ...
In the other kites, the feathers are longer and softer, with fewer barbules towards the tips. Thus, more of the skin is exposed. The head and neck feathers of the crested honey buzzard are shorter, being only 50–70% the length of the feathers in the other two species. [18] The crested honey buzzard may have also evolved a chemical defense.
Buteos are fairly large birds. Total length can vary from 30 to 75 cm (12 to 30 in) and wingspan can range from 67 to 170 cm (26 to 67 in). The lightest known species is the roadside hawk , [ a ] at an average of 269 g (9.5 oz) although the lesser known white-rumped and Ridgway's hawks are similarly small in average wingspan around 75 cm (30 in ...
The similarity in plumage between juvenile European honey buzzard and common buzzard may have arisen as a partial protection against predation by Eurasian goshawks. Although that formidable predator is capable of killing both species, it is likely to be more cautious about attacking the better protected Buteo species, with its stronger bill and ...
Most birds experience an annual molt, typically after the breeding season, Shultz said, but species like American goldfinches replace their feathers twice a year.
A small sample of 5 augur buzzard weighed an average of 973.2 g (2.146 lb) while 22 birds averaged 131.5 cm (4 ft 4 in) in wingspan. [9] The adult augur buzzard is strikingly plumaged and essentially unmistakable if seen well. It is an almost black brown above with a rufous tail that stands out strongly in contrast. The primary flight feathers ...
The red-necked buzzard normally hunts by sitting in wait on a perch, scanning the ground for prey which is caught by a swooping dive down on to the prey. It is a generalist hunter and the prey taken consists of a wide variety of small animals including rodents, birds, lizards and snakes, as well as arthropods and especially termites. [5]
