(Accipitridae; Ϯ Rufous Crab Hawk B. aequinoctialis) Compound of genera Buteo de Lacépède, 1799, buzzard, and Gallus Brisson, 1766, fowl (e.g. turkey); the Rufous Crab Hawk, by reason of its bare face, short tail, small head, heavy body, and long reticulated legs, was considered to resemble the Turkey Vulture (cf. "Buteogallus anthracinus ... A black Buteonine Hawk with exceptional width of wing, long chicken-like yellow legs." (Peterson 1961)); "III.e Sous-genre. BUSON; Buteogallus. Bec long, d'abord droit, à bords renflés pour simuler une dent; mandibule inférieure échancrée au bout; face nue; narines ouvertes, petites, arrondies, dorsales; bec comprimé sur les côtés; ailes concaves, n'atteignant que le milieu de la queue; celle-ci rectiligne, courte; tarses assez longs, emplumés jusqu'au genou seulement, squameux en avant, réticulés sur les côtés et en arrière; tête petite, corps lourd et massif. BUSON CATHARTOÏDE; Buteogallus cathartoides. Falco buson, Lath., Shaw; le Buson, Levaill., Afriq., pl. 21; Caracara buson, Vieill., Encycl., t. III, p. 1182. ...
