Peek-a-boo! This beautiful male Prothonotary Warbler looks as if it is poking its head out of a nest box; it had almost landed on my hiking boot and immediately went to work searching for insects trapped in spider webs between the decking planks and the raised edge of the wooden boardwalk. Photographed during my Songbirds of Pelee Workshop in Point Pelee National Park of Canada on May 7, 2024.
