Members of the genus Buteogallus are small to quite large hawks. Their wings are short to medium in length; broad and rounded; the tail is of medium length. They have coarse, heavy, rather long legs. The lores and adjacent areas are naked to varying degrees. Some feathers on the crown and nape are pointed, forming a slight crest. Adults are blackish with a white banded tail and often with some rufous in wing and (in one species) body plumage. Immature plumage is very different from adult.
The genus is present from south-western United States to Argentina, including the islands of Cuba and St Vincent. There are five species.
Yellow eyes. Dark plumage, darker on the crown and back
White undertail coverts. Feet set far back on body and trail awkwardly behind body in flight. Sexes similar.

Very local, mainly in subtropical parts of the Americas. It may favour small temporary waters which lack predatory fish. It also occurs in swamps, shallow lakes, or oxbows, often almost overgrown with floating vegetation.
The least grebe is rare in freshwater swamps in Suriname near the coast. Birds have also been found in ponds or rivers farther in to the interior.
