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.
Breeds on shallow freshwater lakes, bays of larger lakes, marshes, and other inland bodies of water. Winters on open ocean or on large lakes.
