Pale-legged Hornero

The pale-legged hornero (Furnarius leucopus) is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Bolivia, Brazil, Guyana, and Peru. == Taxonomy and systematics == The pale-legged hornero's taxonomy is unsettled. The International Ornithological Committee (IOC), BirdLife International's Handbook of the Birds of the World (HBW), and the Clements taxonomy assign it these four subspecies: F. l. leucopus Swainson, 1838 F. l. tricolor Giebel, 1868 F. l. araguaiae Pinto & Camargo, 1952 F. l. assimilis Cabanis & Heine, 1860 The South American Classification Committee of the American Ornithological Society (SACC) adds three others, F. l. cinnamomeus (Lesson, 1844), F. l. longirostris (von Pelzeln, 1856), and F. l. endoecus (Cory, 1919). The IOC, HBW, and Clements treat cinnamomeus as the species Pacific hornero and the other two as the Caribbean hornero. Early authors (e.g. Chapman) had treated them separately. The SACC accepts that cinnamomeus may deserve species rank but declined to make the split due to "insufficient published data". Some authors have treated what is now the pale-billed hornero (F. torridus) as a subspecies of the pale-legged hornero. This article follows the four-subspecies model. == Description == The pale-legged hornero is 15 to…
