2-8-2017 CENTRAL PARK, BUDAPEST - BATELEUR EAGLE (Terathopius ecaudatus)

The Bateleur (Terathopius ecaudatus) is a medium-sized eagle known for its striking appearance and unique flight characteristics. It is the sole member of the genus Terathopius and is closely related to snake eagles. Adults are predominantly black with chestnut on the mantle, rump, and tail, and have distinctive red facial skin and feet. Juveniles are drab brown with paler scaling. The species is characterized by a very large head, small bill, large feet, short legs, long wings, and an exceptionally short tail, which is even shorter in adults.

Adult Bateleurs are unmistakable with their black and chestnut plumage, grey wing patches, and bright red cere and feet. In flight, they exhibit elongated, narrow wings that appear pinched at the bases and pointed at the tips. The juvenile's longer tail and uniform brown coloration distinguish it from adults.

Bateleurs favor open savanna habitats with some trees and dry woodlands across Sub-Saharan Africa. They require leafy trees for nesting and are often found near watercourses.

This species is widespread throughout Sub-Saharan Africa and marginally into Arabia. It is more common in protected areas and has experienced significant declines in certain regions.

Bateleurs are highly aerial, spending much time soaring with a distinctive rocking motion. They are solitary but may form loose congregations at rich feeding areas. They are sensitive to disturbance, especially at the nest, and can become unusually tame in captivity.

Bateleurs are generally silent but may emit a loud, raucous "schaaaa-aw" when excited or during courtship. They also produce resonant barking calls and softer calls near the nest.

Bateleurs build small but sturdy stick nests in large trees and lay a single egg. They may take up to 7 to 8 years to reach full maturity. The species is known for its elaborate courtship displays.

Juvenile Bateleurs could be confused with brown snake eagles due to their similar size and proportions, but the latter have yellow eyes and longer legs.

Bateleurs have a generalist diet that includes carrion and a wide range of live prey, such as mammals, birds, and reptiles. They forage from flight, often descending in tight spirals to investigate potential food.

The Bateleur is classified as Endangered by the IUCN due to pronounced population declines caused by habitat destruction, pesticide usage, and persecution. The species is mostly confined to protected areas today.

Bateleur is French for 'tightrope-walker'. This name was probably chosen because of its distinctive aerial acrobatics.

A very distinctive, short-tailed eagle. Young birds are uniformly dark brown, and adults are mostly black with a bright red face and legs. Sexes differ, especially in flight, and can be told by the width of the black band on the back edge of the white underwing: narrow in females, broad in males. It flies low when foraging, with wings raised above the body and rocking from left to right in an unstable-looking fashion. Bateleurs hunt small animals and eat carrion, and they are often among the first raptors to arrive at a carcass.
