Range and Habitat
Red-necked Grebe: Breeds from Alaska and northern Canada south to Oregon, Idaho, Ontario, and southern Minnesota; rarely east to southern Quebec. Spends winters south along coasts to southern California and Georgia, and rarely to Florida. Summer habitats include ponds and lakes; found on large lakes, coastal bays, and estuaries during winter and migration.
Breeding and Nesting
Red-necked Grebe: Two to six light blue or pale buff eggs are laid on a floating nest made of dead reeds and grass; rarely nests in colonies. Incubation ranges from 20 to 23 days and is carried out by both parents.
Foraging and Feeding
Red-necked Grebe: They feed on small fish, crayfish, aquatic insects, tadpoles, salamanders and aquatic plants. They are visual predators. They pursue prey underwater, and pluck items off the bottom and off vegetation. They capture prey by grasping, with a quick snap of their mandibles. Usually they swallow prey underwater, but they bring larger items that are difficult to handle to the surface.
Vocalization
Red-necked Grebe: Usually silent, but emits a variety of squeaks, growls, and wailing calls on breeding grounds.
