Pied-billed Grebe
Podilymbus podiceps (Linnaeus, 1758)
Birds
Family: Grebes (Podicipedidae)

State Protection: Threatened
A native species likely to become an endangered species within the foreseeable future in New York (includes any species listed as federally Threatened by the United States). It is illegal to take, import, transport, possess, or sell an animal listed as Threatened, or its parts, without a permit from NYSDEC. 1) Any native species likely to become an endangered species within the foreseeable future in New York. 2) Any species listed as threatened by the U.S. Department of the Interior.

Federal Protection: Migratory Bird Treaty Act
The Migratory Bird Treaty Act implements various treaties and conventions between the U. S. and Canada, Japan, Mexico and the former Soviet Union for the protection of migratory birds. Under this Act, taking, killing, or possessing migratory birds, including nests or eggs, is unlawful unless specifically permitted by other regulations.


State Rarity Rank: S3B,S1N
A State Rarity Rank of S3B,S1N means: Typically 21 to 100 breeding occurrences or limited breeding acreage and typically 5 or fewer non-breeding (usually winter residents) occurrences in New York State.

Global Rarity Rank: G5
A Global Rarity Rank of G5 means: Demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery.


Did you know?
Both sexes build a large sodden, floating nest of rotting and green plant material and mud. The decomposition of plant material generates substantial quantities of heat, up to 11-13C higher than the surrounding water, providing enough heat to incubate the eggs in the adults' absence (Davis et al. 1984). Like other grebe species (Nuechterlein and Buitron 2002) this may afford the adults the ability to roost comunally at night to minimize predation risk.

State Ranking Justification [-]
The pied-billed grebe was recorded as a probable or confirmed breeder in 150 USGS topographical quads during the second New York State Breeding Bird Atlas (2000-2005), and as a possible breeder in an additional 115 quads. Overall, the species is considered a rare to uncommon, local breeding species with many of the records clustered in areas of large wetland complexes. Although it was recorded in significantly more quads during the Atlas 2000 project in comparison with the first New York State Breeding Bird Atlas in the mid-1980's, Breeding Bird Survey records indicate a - 2.0% annual trend between 1980 and 2002 (New York State Department of Environmental Conservation 2006) and the species is state listed as Threatened. Loss of wetlands and other factors continue to pose threats to the species although a number of excellent occurrences are on protected state and federal wetland complexes.
