FILE - In this Saturday, May 1, 2010 file photo, a least tern checks her two eggs on the beach in Gulfport, Miss. Once hurt the by the damning of major rivers like the Missouri and before that diminished by hunting for feathers for hats, the interior tern population has increased tenfold in population since 1985 to more than 18,000. On Wednesday, Oct. 23, 2019, the U.S. Fish and Wildlife Service will propose taking the interior population of the least tern off the endangered list. (AP Photo/Dave Martin)
