Northern Parula

A distinctive buzzy trill that ascends and then ends abruptly with a higher-pitched snap. Often written as "zzzzzzzziip" or "rising zeeeeee-up." It's a short song (1-2 seconds) that starts with a buzzy monotone then leaps up in pitch at the end. Males repeat this frequently from canopy perches in spring. Some describe it as sounding like a mosquito whining and then being zapped.

Strongly migratory. Summers in the eastern United States (from Gulf Coast states to New England and southern Canada) and parts of the Upper Midwest; also a separate breeding population in parts of Texas/Oklahoma. Winters mainly from coastal South Florida and the Keys southward through the West Indies and into Central America. Absent from US during winter except Florida and rare strays along Gulf. Arrives early for a warbler (often March in the South, April in the North) and departs by mid-fall (many gone by October).

Breeds in mature forests, particularly those with hanging lichens or Spanish moss. In the Southeast, commonly nests in swamps and bottomlands where Spanish moss is available. In the North, favors moist forests (often near streams or bogs) with beard lichens (Old Man's Beard) hanging from branches – they use these lichens to conceal their nests. Often at mid to upper canopy level. During migration, can be found in any wooded habitat, including parks and wooded yards. Winters in southern Florida (small numbers) and primarily in the tropics (Caribbean, Mexico, Central America) in forest edges and shade coffee plantations.

One of the earlier warblers to arrive in spring in many areas. Males start singing their buzzy trill songs upon arrival to establish territories in late March or April. Pairs build nests in hanging Spanish moss or lichen in April/May, and generally raise one brood. By mid-summer, singing subsides after nesting. During late summer, they often remain out of sight in the treetops as they fatten up for migration. Fall migration peaks in late August through September. On wintering grounds, they join mixed flocks and are relatively quiet, though may chip occasionally. By late February and March, some begin moving north, and Florida sees an influx of migrants on their way back to breeding areas. Their distinctive song can be heard in southern states by early spring even before trees fully leaf out.

Tiny, brightly colored wood-warbler. Bluish-gray above with a greenish patch on the back. Bright yellow throat and chest, with a distinct dark (reddish-brown and black) band across the breast in adult males; females have a much fainter or absent band. White belly and undertail. Bold white eye arcs (above and below eye) give a broken eye-ring effect. Often seen flitting high in trees, sometimes hanging upside down from clusters of moss or leaves while foraging.
