The Mourning Warbler is a small species of New World warbler that migrates between breeding grounds in southern parts of Canada and the northeast United States and its winter range in northern South America.
Mourning Warblers have a chunky appearance. Breeding adult males, like our Birdorable version, have a grey hood, dark chest patch, olive back and yellow underparts. Females have a similar color scheme but with more muted tones.
Mourning Warblers prefer forest habitat for breeding, including disturbed forests. They nest near the ground or on the ground, forming an open cup nest made up of vegetation and hair.
