Roseate Tern U.S. Fish and Wildlife Service
Family: Terns, Gulls and Relatives (Laridae)

State Protection: Endangered
A native species in imminent danger of extirpation or extinction in New York (includes any species listed as federally Endangered by the United States). It is illegal to take, import, transport, possess, or sell an animal listed as Endangered, or its parts, without a permit from NYSDEC. 1) Any native species in imminent danger of extirpation or extinction in New York. 2) Any species listed as endangered by the United States Department of the Interior.

Federal Protection: Endangered
Listed as Endangered in the United States by the US Department of Interior.

State Rarity Rank: S1B
A State Rarity Rank of S1B means: Typically 5 or fewer breeding occurrences and very limited breeding acres, making it especially vulnerable in New York State.

Global Rarity Rank: G4
A Global Rarity Rank of G4 means: Apparently secure globally, though it may be quite rare in parts of its range, especially at the periphery.

Did you know?
Over 90% of New York's Roseate Terns breed at a single location, Great Gull Island, on Long Island. It is also a globally significant breeding colony because of its size.

State Ranking Justification [-]
There are only two sizeable colonies in New York and a large percentage of the statewide population nests at a single location. Roseate Terns are threatend by the loss of breeding habitat to coastal development and rising sea-levels, human disturbance, predation, and increased flooding from storms due to climate change. Buckley and Buckley (1981) cited evidence that North Atlantic populations may be relict while the species origination and core distribution is tropical. Roseate Terns are listed as endangered in the state by the NY Department of Environmental Conservation and the northeatern U.S. population is federally-listed as endangered.
