Black and White Warbler by Georgie Alexon Via Flickr: The Black-and-white Warbler is the only member of the genus Mniotilta. The genus name means “moss-plucking,” a reference to its habit of probing bark and moss for insects. Black-and-white Warblers have an extra-long hind claw and heavier legs than other wood-warblers, which help them hold onto and move around on bark. - All About Birds Taken in Corkscrew Swamp Sanctuary, Florida -Mniotilta varia
