White Tern
The White Tern is one of eight seabird species whose population density and susceptibility to sea-level rise was studied on the French Frigate Shoals' Tern Island by biologists with the USGS Pacific Island Ecosystems Research Center's Northwestern Hawaiian Islands Climate Change Project.
