The Northeast population of Roseate Terns is endangered. Each summer, roughly twenty-five hundred Roseate Terns are found on Ram Island, a 2.5-acre island off the coast of Massachusetts. In the 1960s and 70s, gull numbers surged. Gulls drove terns off of Ram Island, until biologists began chasing off the gulls to encourage terns to nest there again. Their efforts were successful: today, about one in five Roseate Terns in North America nests on the island. The site is designated as an Important Bird Area (IBA.)
