The Ridgway's Hawk, (Buteo ridgwayi), is a bird of prey in the family Accipitridae, which also includes the eagles, hawks and Old World vultures. Despite the name, this bird is a Buteo buzzard and not a true Accipiter hawk.
The Ridgway's Hawk original breeding range included Haiti and the Dominican Republic (which make up the island of Hispaniola) and some of the adjacent isles and keys. As of 2006, its only known population resides within Los Haitises National Park, in Northeastern Dominican Republic, which is mostly covered by wet limestone forest.
This is a medium-sized, compact hawk, 36-41 cm long. The adult has brown-grey upperparts, greyish barred underparts with reddish-brown wash, rufous-tinged thighs and a black-and-white barred tail. The male is greyer than the female. The legs and base of bill are yellow. Immature birds have buffy white underparts with grey and brown streaks.
This bird feeds on small mammals, birds, lizards and snakes. It nests in the crowns of tall trees, with nest-building in February and March and eggs laid in March and April.
This bird is critically endangered due to clearance of its forest habitat and direct persecution by local farmers, who erroneously believe the species preys on domestic fowl, even though reptiles comprise up to 90% of its diet. It has an estimated population of 80"?120 pairs, making it, along with the Bay-breasted Cuckoo (Coccyzus rufigularis), the most threatened bird of Hispaniola.
This bird is named after the ornithologist Robert Ridgway.
