Buteo ridgwayi (Ridgway's Hawk)

Wikipedia Abstract

Ridgway's hawk (Buteo ridgwayi) is a bird of prey in the family Accipitridae, native to the island of Hispaniola. Despite its common name, this bird is a Buteo buzzard and not a true Accipiter hawk. It was named after the American ornithologist Robert Ridgway. It is a brownish-grey bird with barred tail and underparts. It feeds mainly on reptiles, but also consumes small birds and mammals. It nests high in a tree in spring. Populations of this bird have been declining because of habitat destruction and human persecution, and it is now only found in the Los Haitises National Park in the Dominican Republic and is regarded as "critically endangered".
