A duck-like-diver that are at first glance similar to a loon, Red-necked Grebes, like all grebes, are smaller, have flat, lobed toes, and appear tailless. A migratory aquatic bird, they are great swimmers, nimble divers and respond to threats of danger by diving instead of flying. This grebe is a rare, but welcome winter visitor to the open lakes of Tennessee.
Description: The Red-necked Grebe is a fairly large and stocky with a broad triangular head and thick neck. The reddish neck and breast contrasting with the white cheeks, black cap and dark body is quite stunning when compared to the winter plumage that appears somewhat dingy with a brown body, blackish cap and pale-gray crescent patch extending from the chin to behind the ear. The long, heavy bill is yellow and angles downward in all plumages. Red-necked grebe fly in straight line formations with rapid, direct strong wing beats and are the only grebe to show a white leading edge and white trailing edge on their inner wings when in flight.
