Cape May Warbler (Setophaga tigrina) lives in boreal coniferous forest across Northern North America. It feeds on insects and nectar. Its conservation status is Least Concern.

A real field recording of the Cape May Warbler, made in the wild.
The Cape May warbler is an extremely rare vagrant to western Europe, with only two British records recorded by October 2013. It normally breeds across most of southern Canada, the Great Lakes region and New England before migrating south. In winter it spends the season in the West Indies, a route that keeps it far from Europe. Its occasional appearance there is therefore a notable exception to its usual distribution.
In winter the Cape May warbler supplements its insect diet by drinking berry juice and nectar, a behaviour made possible by its uniquely tubular tongue, a feature no other warbler possesses. This adaptation allows it to exploit sugary resources when insects are scarce. The bird also continues to pick insects from conifer tips or catch them in flight during the non-breeding season. Thus its diet in the West Indies combines both protein and carbohydrate sources.
When spruce budworm populations surge, the Cape May warbler can lay a clutch of four to nine eggs, the largest clutch of any New World warbler. The increased brood size likely takes advantage of the sudden abundance of this key insect prey. The species nests in dense foliage near the trunk of conifer trees, often black spruce, during the breeding season. This strategy links reproductive output directly to food availability in its coniferous woodland habitat.
The species was described in 1812 by Alexander Wilson based on a specimen collected at Cape May, New Jersey. After that capture the species vanished from local records for a full century.
The warbler's English name directly commemorates the New Jersey town where its type specimen was gathered, linking the bird forever to Cape May. Alexander Wilson coined the name after examining the specimen collected by George Ord at that location. This naming convention ties the species' identity to the place of its first scientific documentation. Consequently, every reference to the Cape May warbler evokes its original discovery site.

As the Cape May Warbler flits through the dense thickets of its boreal forest home, its bright yellow breast and streaked belly seem to glow like embers, illuminating the dappled shade. With a twitch of its tail and a flick of its wing, this tiny, tireless songster darts from branch to branch, its melodic trill punctuating the stillness like a burst of crystal clarity. In its ceaseless quest for insects and sap, the Cape May Warbler embodies the very essence of spring's irrepressible vitality, a whirlwind of energy and life that animates the northern woods.
