Hieraaetus-pennatus, Booted Eagle, Elang Setiwel

The Booted Hieraaetus-pennatus, Booted Eagle, Elang SetiwelEagle (Aquila pennata) (formerly Hieraaetus pennatus) is a medium-sized bird of prey. It is about 47 centimeters (18 inches) in length and has a wingspan of 120 cm (almost 4 feet). Like all eagles, it belongs to the family Accipitridae.
It breeds in southern Europe, North Africa and across Asia. It is migratory, wintering in Sub-Saharan Africa and South Asia. This eagle lays 1-2 eggs in a tree or crag nest.

This is a species of wooded, often hilly countryside with some open areas. It hunts small mammals, reptiles and birds.

The Booted is a small eagle, comparable to the Common Buzzard in size though more eagle-like in shape. Males grow to about 700 grams (1.5 lbs) in weight, with females close to 1 kilogram (over 2 lb). 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.

Recent genetic research[citation needed] resulted in the reclassification of this species to the genus Aquila from Hieraaetus. As it is the type species of Hieraaetus, should any of the hawk-eagles be retained in a distinct genus a new name for that group would be necessary.

Along with the Little Eagle this bird is one of the closest living relatives of the extinct Haast’s Eagle of New Zealand.
