Named after the black patch on the male's upper breast, giving
the impression of being dressed in mourning. The Mourning Warbler is a
bird of shrubby areas and forest undergrowth, and is often difficult to
spot. Unlike many migrants, Mourning Warblers avoid flying over the Gulf
of Mexico during the spring and fall, instead preferring to migrate overland
through Mexico and the interior of the U.S.
shrubby undergrowth and second-growth forest. Can often be found in forest
areas that are regenerating after fire disturbance or clear-cutting.
Diet: Primarily insects,
especially caterpillars and beetles. Also spiders.
Behavior: Moves through low shrubs and forest
undergrowth, gleaning insects and spiders from the foliage. Will also
fly out to capture flying insects in mid-air, and will forage while hopping
along the ground.
Breeding: Non-breeder in South Dakota.
Song: 2-part song, with
2nd part lower than the first part, jirry-jirry, jorry-jorry.
Migration: Summers through southern Canada, the northern Midwest, and the northeastern
U.S. Neotropical migrant, wintering in Central and South America.
Conservation Status: Generally stable. Its
preference for second-growth forest makes it less susceptible to habitat
loss than many species.
