The booted eagle (Hieraaetus pennatus, also classified as Aquila pennata) is a medium-sized mostly migratory bird of prey with a wide distribution in the Palearctic and southern Asia, wintering in the tropics of Africa and Asia, with a small, disjunct breeding population in south-western Africa. Like all eagles, it belongs to the family Accipitridae.
Description:
The booted is a small eagle, comparable to the common buzzard in size though more eagle-like in shape. Males grow to about 510-770 g in weight, with females about 840-1,025 g with a length of 40 cm and a wingspan of 11-132 cm. There are two relatively distinct plumage forms. Pale birds are mainly light grey with a darker head and flight feathers. The other form has mid-brown plumage with dark grey flight feathers.
The call is a shrill kli-kli-kli.
