In the breeding season the Red-necked Grebe chooses lakes with edges of emergent vegetation. The nest of reeds, rushes, sedges, and marsh grass is placed on a floating mat of vegetation.

Habitat: Lakes, ponds; in winter, salt water. Summer: On freshwater lakes or large ponds having some marsh vegetation, surrounded by prairie, northern forest, or sometimes tundra. Winter: Mostly on ocean, on protected bays but also miles offshore at times; also a few on some large lakes.

Diet: Mostly insects and fish. Diet varies with season. May feed mainly on small fish in winter on coastal waters; in summer on marshes and ponds, feeds mainly on insects. Also eats crustaceans, mollusks, tadpoles, nereid worms, very small amounts of plant matter. Like other grebes, may eat feathers.

Nest: Site is in shallow water among marsh vegetation. Nest is a floating mass of plant material with a definite depression at the top, anchored to standing plants.
