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. Other names of this grebe include American dabchick, dabchick, Carolina grebe, devil-diver, dive-dapper, dipper, hell-diver, pied-billed dabchick, pied-bill, thick-billed grebe, and water witch.
The pied-billed grebe was described by Carl Linnaeus in the 10th edition of his Systema Naturae in 1758 as Colymbus podiceps. The binomial name is derived from Latin Podilymbus, a contraction of podicipes (“feet at the buttocks”, from podici-, “rump-” + pes, “foot”)—the origin of the name of the grebe order—and Ancient Greek kolymbos, “diver”, and podiceps, “rump-headed”, from podici- + New Latin ceps.
