The Cape May Warbler leads very different lives during the summer and winter months. During the summer, they are most often found in spruce forests, where they have access to their favorite summer food item, spruce budworms. They spend their winter on Caribbean islands and in southern Florida, where much of their diet may shift to nectar, sap, and juices obtained from puncturing fruit. The Cape May Warbler is the only warbler with a tubular tongue adapted to feeding on nectar from flowers.
Habitat
During the summer breeding season, they are found in spruce forest, usually in open forests or near woodland edges. During migration, they also prefer conifers but can be found in deciduous trees and brushy thickets as well. They are often found in palm trees during their winter months in the Caribbean and Florida.
Diet
In the summer, they primarily feeds on insects, and are especially fond of spruce budworms. During migration and in winter, they often feed on nectar, and juice obtained by piercing fruits. They will also drink sap from sapsucker drill holes.
Behavior
On summer on its preferred spruce forest habitat, usually feeds at the end of spruce branches in search of insects. They will also occasionally fly out from a perch to capture insects in mid-air.
Breeding
Non-breeder in South Dakota
Song
A high-pitched see-see-see-see.
Migration
Summers throughout central and southeastern Canada, the Great Lakes region, and northern New England. Winters in the Caribbean and southern Florida.

Conservation Status
Possibly has become more common in recent decades. Populations seem to boom and bust with populations of spruce budworms, a favorite food item.
