    Conservation

    Conservation DecliningThere is little information on population trends of Roseate Tern, but they appear to be a declining species. The North American Waterbird Conservation Plan estimates a continental breeding population of 16,000 birds, rates the species a 15 out of 20 on the Continental Concern Score, and lists it as a Species of High Concern. North American populations are on the 2014 State of the Birds Watch List, which lists species most in danger of extinction without significant conservation action. The U.S. Fish and Wildlife Service lists Roseate Tern populations in Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, New York, North Carolina, Rhode Island, and Virginia as Endangered. Populations in Florida, Puerto Rico, and the Virgin islands are listed as Threatened. Roseate Tern is listed as Threatened by the Canadian Wildlife Service,Back to top
