Justification:
This species is thought to have a small global population and is considered Near Threatened. If further infomation indicates that its total population falls below 1,000 mature individuals, it would qualify for uplisting to Vulnerable.

History:

2008	–	Near Threatened
2004	–	Near Threatened

Geographic Range [top]

Range Description:	Buteo ventralis is endemic to the lower Andes of Patagonia in southern Chile and Argentina, where it is rare, occurring at naturally low densities. No data is available regarding numbers or densities, and there is no firm evidence of a decline, but its habitat has suffered extensive degradation and some authorities consider that the total population is unlikely to exceed 1,000 individuals (Ferguson-Lees and Christie 2001). Further information is required regarding population size, trends and other potential or existing threats. Increased knowledge of identification features may generate more records of this species.
