resembling the syllables '_swee-e-e-e-e, chee-chee-chee-chee_,' the
first inhaled, the second exhaled."[152]
Habitat: "The Blue-winged warbler frequents swampy thickets but is
sometimes found among the scrubby second growth of the hillsides and
the undergrowth of dense woods."[152]
Range: Breeds in eastern North America from southeastern Minnesota,
southern Michigan, western New York, Connecticut, and Massachusetts,
southward to Missouri, Kentucky, Maryland, and Delaware; winters
from southern Mexico to Colombia.
"The Blue-winged Warbler is deliberate in its movements as compared with
other warblers, acting more like a vireo than a member of its family.

The nesting site of this warbler is on the ground in a bunch of herbs or
at the foot of a small bush. The nest is surrounded by grass, weeds,
ferns, or vines, which screen it effectively from view."[152]
