Feeding

In the summer, horned grebes eat aquatic arthropods, and in the winter, fish and crabs. Leeches, tadpoles, salamanders, and plant debris are occasionally eaten. Mollusks are eaten at the wintering grounds. Horned grebes dive for their prey. They can consume little objects underwater but must bring huge ones to the surface to handle.

Habitat

Horned grebes nest in prairie and boreal freshwater lakes with open water and marsh vegetation. They nest in marshes, weedy sloughs, ponds, and rivers. These birds spend the winter in sheltered bays and exposed shorelines along the coast, as well as huge freshwater lakes.

Behavior

Horned grebes can swim and dive well. They can dive for up to three minutes and go 150-200 meters. They can also regulate their specific gravity to float higher in the water. Horned grebes are elegant on water but clumsy land. Their legs are so far back that they can hardly walk.
