Podiceps grisegena
The Red-necked Grebe breeds on small inland lakes in Canada and Alaska, and winters along both coasts of North America. Boldly marked, vocal, and aggressive during the breeding season, it is quiet and subtly attired in winter. Cool Facts Like other grebes, the Red-necked Grebe ingests large quantities of its own feathers. Feathers remain in the bird's stomach. The function of feathers in the stomach is unknown. One hypothesis suggests that the feathers help protect the lower digestive tract from bones and other hard, indigestible material. The Red-necked Grebe also feeds its feathers to its young. The Red-necked Grebe migrates over land strictly at night. It sometimes migrates over water or along coasts by day, in large flocks.
Nest Description Floating mound of plant matter with a depression in the middle; bulk of nest is below water line. Nest is placed on aquatic vegetation, sometimes in open water, and anchored to the lake bottom or submerged logs.
