Large grebe with heavy, tapered, yellowish bill almost as long as the head. Length 20 in (51 cm).
Usually silent. On breeding grounds, a variety of squeaks, growls, and wailing calls.
Ponds and lakes in summer; large lakes, coastal bays, and estuaries in winter and migration.

Highly aquatic, grebes can swim with only their heads above water, concealing themselves in low pond vegetation.
