Habitat

In summer, bogs in the North; during migration, open places, especially weedy fields and borders of marshes.

Range

Breeds from west-central Canada east to Labrador and Newfoundland, and south to extreme northern portions of United States. Winters from southeastern United States southward.

Discussion

The Palm Warbler is one of the first warblers to arrive in the spring, and at this season is commonly found feeding quietly on the ground, sometimes with flocks of sparrows. It is unusual among warblers of the genus Dendroica in nesting on the ground; the only other species that does this is the rare Kirtland's Warbler.

Nesting

4 or 5 brown-speckled white eggs in a grass nest fashioned with shreds of bark and lined with feathers and rootlets. Nest is placed on the ground in a grass clump, often at the base of a small tree or bush.
