DEFINITIONS

PARABUTEO
(Accipitridae; Ϯ Harris's Hawk P. unicinctus harrisi) Gr. παρα para  near; genus Buteo de Lacépède, 1799, buzzard; "GENUS ANTENOR, Ridgway  ...  (Type, Falco harrisi, AUD.)  ...  This genus includes a single species, the P. unicinctus, with its two climatic races, unicinctus of South America and harrisi of Middle America. It is most nearly related to the genus Urubitinga, of tropical America, the species of which are sluggish and almost Caracara-like in their habits, though they are hardly more so than our own Buteones  ...  Parabuteo unicinctus, var. harrisi (RIDGWAY).  HARRIS'S BUZZARD.  ...  He [Dresser] describes it as a heavy, sluggish bird, seldom seen on the wing, and subsisting, so far as he could see, entirely on carrion. All along the road from Brownsville to San Antonio, he noticed it either perched on some tree by the roadside, or busy, in company with Vultures and Caracaras, regaling on some offensive carrion." (Ridgway 1874); "Parabuteo Ridgway, in Baird, Brewer and Ridgway, Hist. No. Am. Bds., 3, 1874, p. 250. Type, by monotypy, Buteo harrisi Audubon." (Peters 1931, 1, 240). This raptor, now widely used in falconry, was formerly known as Bay-winged Hawk.
