This wee little grebe is dark gray overall with paler fluffy bum. The face is dark in breeding plumage; paler with a whitish throat in nonbreeding plumage. Also note piercing yellow eye and thin, sharply pointed bill. Compare with Pied-billed Grebe, which is larger, browner, and thicker-billed. Widespread throughout Middle and South America; very limited range in the U.S. Found in marshy ponds, often with extensive vegetation. Usually seen singly or in pairs, sometimes in small groups. Frequently dives underwater.
