Mourning Warbler

This warbler breeds in dense, tangled secondary growth and forest edges across Canada and the northeastern United States, staying low in thick cover where it is far more often heard than seen. Males give a loud, rolling song and show a distinctive gray hood contrasting with a yellow belly, best glimpsed when a bird briefly rises to sing from a low perch. Spring migration and the early breeding season offer the best chance of a view, since birds become much harder to locate once nesting is underway.
