    Conservation

    Conservation Restricted RangeThere is little information on Elegant Tern population trends. The North American Waterbird Conservation Plan estimates 34,000-60,000 breeding birds on the continent, and lists it as a Species of Moderate Concern. Elegant Tern rates a 16 out of 20 on the Conservation Concern Score, and is on the 2016 State of North America's Birds' Watch List, which includes bird species that are most at risk of extinction without significant conservation actions to reverse declines and reduce threats. The species is listed as Near Threatened on the IUCN Red List. Elegant Tern appear to be more widespread and abundant in southern Gulf of California than in the past. The species now nests mostly on one island, Isla Rasa, Mexico. Its limited distribution, and annual fluctuations at some colonies, are due at least in part to deleterious effects of humans and feral animals.Back to top
