Taxonomic CommentsHere includes Buteogallus anthracinus subtilis (Stiles and Skutch 1989; Howell and Webb 1995; Ridgely and Greenfield 2001). Formerly included B. gundlachii, now separated because of differences in size, plumage and voice (Wiley and Garrido, 2005).

Threat ImpactHigh
Range Extent>2,500,000 square km (greater than 1,000,000 square miles)
Rank ReasonsWidespread in appropriate habitat; however, there are some concerns over the long-term health of the required riparian and freshwater habitats.
Range Extent CommentsBREEDING: Resident from central (rarely northwestern) Arizona, southwestern Utah (rarely), southern (rarely central) New Mexico, and western and (formerly) southern Texas, south through Mexico and Central America to northern Colombia, and east through coastal Venezuela and Trinidad to Guyana, French Guiana, and in the Lesser Antilles on St. Vincent. NON-BREEDING: Northernmost breeding populations in the southwestern United States and northwestern Mexico usually migrate southward in nonbreeding season (AOU 1998). Casual or accidental in southern Nevada, northcentral Texas, southern and western Texas away from breeding areas, and the Lesser Antilles; sight records from southern California and northern Baja California. Reports from Minnesota and southern Florida are probably based on escaped individuals, and may pertain in part to B. urubitinga (AOU 1998).
Threat Impact CommentsThreatened in the United States by the alteration or elimination of riparian habitat through clearing, water diversion, diking and damming, and lowering of the water table by underground pumping (Schnell et al. 1988, Schnell 1994). At least 95% of the riparian habitat in the southwestern United States have been lost, altered, or degraded (Ohmart 1994). Presumably, similar threats exist in other parts of the range.
