Puerto Rican Broad-Winged Hawk and Puerto Rican Sharp-Shinned Hawk ('Buteo platypterus brunnescens' and 'Accipiter striatus venator') Recovery Plan.

摘要

The Puerto Rican broad-winged hawk (Buteo platypierus brunnescens) and the Puerto Rican sharp-shinned hawk (Accipiter straiatus venator), both endemic to the island of Puerto Rico, are currently restricted to montane forests along the Cordillera Central, Sierra de Cayey and Sierra de Luquillo. Both species are currently threatened by destruction and modification of forested habitat; timber harvest and management practices in public forests; road construction; the increase in numbers of recreational facilities, and the disturbance associated with public use; mortality and habitat destruction from hurricanes. In addition, both hawks are adversely affected by the lack of comprehensive management plans for the public forests; possible loss of genetic variation due to low population levels; and the potential for illegal shooting. The Puerto Rican sharp-shinned hawk is also affected by warble fly parasitism. Both species were determined to be endangered species on September 9, 1994 (U.S. Fish and Wildlife Service 1994), pursuant to the Endangered Species Act of 1973, as amended. Critical habitat was not designated.
