Myrtle Warbler (Dendroica coronata)

Myrtle warblers are tiny mites that liven up the trees and shrubs in
the spring migration. Traveling in small flocks, they seem to be
constantly in motion. flitting from branch to branch searching for
small insects and their eggs. Like flycatchers, they snap up larger
bugs on the wing. To a quiet observer, they seem trusting birds often
singing at close range.

Some winter as far north as the New England coast, wherever
bayberry thickets offer fruit and shelter, and others move on to the
southern states. From these wintering grounds they migrate to
nesting grounds in the evergreen forest of the northern states and
Canada. In their fall flight south, they seem subdued, the bright
yellow on the crown and flanks having disappeared, and the lemon
colored rump the only remaining brilliant.
