Phalcoboenus

Genus of birds From Wikipedia, the free encyclopedia

Phalcoboenus

Phalcoboenus is a small genus of caracara in the family Falconidae. They are found in barren, open habitats in the Andes, Patagonia and the Falkland Islands. The four extant species are almost entirely allopatric. The adults are distinctive, with bare yellow, orange or red facial skin and cere, and a black plumage with variable amounts of white. Juveniles are overall brown with pale pinkish-grey facial skin and cere. They are highly opportunistic and typically seen walking on the ground, where they will feed on carrion and virtually any small animal they can catch.

The name, meaning "walking falcon",[5] is derived from Greek: φάλκων 'phálcōn' (hawk, falcon) and βαίνω 'baínō' (I go, I walk).[6] The original lithograph print produced for Alcide d'Orbigny is captioned "Phalcobœnus montanus" with an o-e ligature,[7] but his later text has "Phalcobænus montanus" with a-e ligature in "Phalcobaenus".[6]
