The Pied-billed Grebe (Podilymbus podiceps) is a species of the grebe family of water birds. Since the Atitlán Grebe (Podilymbus gigas) has become extinct, it is the sole extant member of the genus Podilymbus. The Pied-billed Grebe is primarily found in ponds throughout the Americas.[2] Other names of this grebe include American dabchick, dabchick, Carolina grebe, devil-diver, dive-dapper, dipper, hell-diver, pied-billed dabchick, thick-billed grebe, and water witch.
Pied-billed Grebes are small, stocky, and short-necked. They are 31–38 cm (12–15 in) in length, with a wingspan of 45–62 cm (18–24 in) and weigh 253–568 g (8.9–20.0 oz).[8] They are mainly brown, with a darker crown and back.[9] Their brown color serves as camouflage in the marshes they live in.[10] They do not have white under their wings when flying, like other grebes.[11] Their undertail is white[9] and they have a short, blunt chicken-like bill that is a light grey color,[2][9] which in summer is encircled by a broad black band (hence the name). In the summer, its throat is black.[2] There is no sexual dimorphism.[11] Juveniles have black and white stripes and look more like winter adults.[2] This grebe does not have webbed feet. Its toes havelobes that come out of the side of each toe. These lobes allow for easy paddling.[2] When flying, the feet appear behind the body due to the feet’s placement in the far back of the body.[9]
It may be confused with the Least Grebe, although that species is smaller and has a thinner bill.
