The Cape May warbler is a species of New World warbler. It breeds in northern North America. Its breeding range spans all but the westernmost parts of southern Canada, the Great Lakes region, and New England. It is migratory, wintering in the West Indies. This species is a very rare vagrant to western Europe, with two records in Britain as of October 2013. The English name refers to Cape May, New Jersey, where George Ord collected the specimen that was later described by Alexander Wilson.
Region
Northern North America and the Caribbean
Typical Environment
Breeds across the boreal forest of southern Canada and the northern United States, especially in spruce–fir stands. During migration it passes through the Great Lakes region, New England, and the eastern U.S., using woodlots, parks, and forest edges. In winter it is primarily in the West Indies and parts of the Caribbean basin, occasionally southern Florida and the Yucatán. Prefers coniferous canopy in the breeding season but is adaptable to fruiting and flowering trees in wintering areas.

Despite its name, the Cape May warbler rarely occurs at Cape May except during migration; the name comes from the locality where the type specimen was collected. It has a semi-tubular, curled tongue that allows it to sip nectar and sap in winter, unusual for a warbler. Populations fluctuate with outbreaks of spruce budworm, a favored prey. It will sometimes visit hummingbird feeders on the wintering grounds.

Temperament
active and agile
Flight Pattern
short rapid wingbeats with quick, bounding movements
Social Behavior
Often forages high in the canopy and joins mixed-species flocks during migration and on the wintering grounds. Breeding pairs are territorial; the female builds a cup nest high in dense conifers, usually near the trunk. Clutches typically contain 4–6 eggs, and both parents feed the young.
Migratory Pattern
Seasonal migrant
Song Description
Song is a high, thin, sibilant series of see-see-see notes, often accelerating and slightly rising, reminiscent of an insect. Call notes are sharp, high tsip or tsee that carry well through the canopy.
