The Great Grebe is the largest of the Podicipedidae. It is distributed widely throughout southern South America, with a disjunct population in Peru. With a very long, thin neck, dagger-like bill, rufous neck, dark back, and whitish underparts, this species is rather unique in appearance. Great Grebes catch fish, crabs, and occasionally the young of other waterbirds by diving. Perhaps in part because of this catholic diet, Great Grebes can be found in most large bodies of water ranging from rocky coasts to marshy estuaries to inland rivers and lakes.
