The Red-necked Grebe (Podiceps grisegena) is a member of the grebe family of water birds. In summertime, adults are unmistakable, due to their red neck and white throat. In winter, the Red-necked Grebe is duskier than most grebes, with no white above the eye, and a thick, yellowish bill. It is a somewhat large grebe, about the same size as an average duck.Photo credit: Mdf
