The Okefenokee National Wildlife Refuge was set aside to protect the fabled Okefenokee Swamp of Georgia and Florida. Tall cypress trees and Spanish moss give the swamp a prehistoric appearance. The Prothonotary Warbler is one of the most striking of the swamp’s denizens. Having wintered in the West Indies, a male might return to the Okefenokee and establish a breeding territory. Because it lives down in the realm of trunks and branches rather than up in the leaves, the Prothonotary has adopted an unusual nesting habit for a warbler: it nests in natural crevices or old Downy Woodpecker holes!
