Red-necked Grebes are known for the wide variety of elaborate courtship displays they participate in, although these are not as common on the breeding grounds as one might expect given that many pairs have formed prior to reaching breeding areas. Storms can produce waves which destroy many Red-necked Grebe nests and eggs.
Red-necked Grebes are very territorial, not only against other Red-necked Grebes but also against other water birds. A variety of chases and attacks are used, including an underwater attack in which the grebe swims underneath the intruder and jabs its underside with its bill.
The Red-necked Grebe is a large grebe with a yellowish bill, dark gray upperparts, and a white throat and cheeks. The reddish neck and breast in breeding plumage give it its name.
When in breeding plumage it is not easily confused with other species. Winter plumage somewhat resembles Earned or Horned Grebe but bill is much larger.
