The Black-collared Hawk is a denizen of most fresh or brackish water habitats in tropical and subtropical Central and South America, occurring from central Mexico south to Uruguay. Typically Black-collared Hawks perch above shallow pools or marshes and drop onto prey, which most often are fish; as in the Osprey (Pandion haliaetus), the undersides of the toes of this hawk have spines to aid in grabbing fish. Other prey includes lizards or rodents. Named for its black bib, the Black-collared Hawk most easily is identified by its rufous plumage and very short tail. This species can be quite common in appropriate habitat but is patchily distributed and local over much of Amazonia.
