In a July 14, 2016 photo, a least tern bird flies over the Gulf of Mexico near Fort Walton Beach, Florida. The least tern nesting season in the Florida Panhandle is from the end of March to the end of August, according to Emily McKiddy of Florida Audubon. Volunteers with the organization were installing safety fences on rooftops on Monday March 6, 2017, in Destin, Fla., to protect the chicks from falling off of the roof when they are born.
