Conservation Status

The Black Hawk-Eagle is not athreatened species. The IUCN Red List status is assessed as Least Concern, mainly because of the large range, within which there remains expansive areas of suitable habitat for this species (BirdLife International 2011). Nonetheless, the actual status of this specie is poorly known and some populations are known to be declining (e.g., in Mexico) (Rangel-Salazar and Enriquez-Rocha 1993).

Effects of human activity on populations

Degradation of forests is the major cause of population declines in this species, following in importance by shooting and pesticide use. Farmers kill the Black Hawk-Eagle because it is said to be of danger to domestic birds (e.g., hens) (Chebez 1999). Hunting reduces prey (e.g. toucans) also affects S. tyrannus populations (Naka et al. 2002).
