Buzzard

Buzzard (baj) name of a group of medium-sized birds of prey belonging to the family Accipitridae, order Ciconiiformes with rounded wings and long tails. Most are brown or grey in colour. There are 27 species of buzzards distributed worldwide except Antarctica and Australia. Bangladesh has 4 species of which two are migratory (Table).

honey buzzards are quite varied in appearance and habits. Some are extremely specialised; the members of genus Pernis eat the grubs and nests of wasps. When in flight they can usually be distinguished from other birds of prey by their broad wings and expansive, rounded tails. When hunting they soar gracefully for hours but in direct flight the wingbeats are slow and heavy. The plumage is dark brown above and white or mottled with brown below. The tail and underside of the wings are usually barred.

They catch small mammals and reptiles on the ground, and occasionally attack birds. Carrion is also eaten. The nest is a large, substantial structure of sticks lined with softer materials and usually placed on a tree or cliff. The whitish eggs (2-5) are blotched or spotted with brown.
