The slate-colored hawk (Buteogallus schistaceus) is a species of bird of prey in the family Accipitridae: the hawks, eagles, and allies. It is found in the Amazon rainforest in Brazil, Bolivia, Peru, Ecuador, Colombia, Venezuela, and French Guiana.
It is a medium-sized to large bird, typically about 40 cm (16 in) long. It is medium slate-grey in color, with contrasting bright white horizontal banding on its tail feathers. It has a medium-white breast with vertical black markings. It has a large orange cere at the base of its beak, and large yellow eyes.
The slate-colored hawk inhabits most of the Amazon rainforest, primarily in várzea and especially in areas near water like rivers, swamps or mangrove. It hunts for frogs, snakes, small mammals, crabs and other small animals, often at the water edges.

GBIF citizen-science records
It is estimated from how often the Slate-colored Hawk is recorded against all the birds logged in Amacayacu National Natural Park (79 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
