The black bear, moose, eastern cottontail, and white-tailed deer feed on the foliage. Domestic sheep commonly avoid low sweet blueberry browse. Flowers and fruit are readily eaten by a wide variety of birds and mammals. Mammal species include black bear, red fox, raccoon, red-backed vole, white-footed mouse, fox squirrel, red squirrel, eastern spotted skunk, gray fox, and many species of chipmunks and mice. Birds include ptarmigan, American robin, common crow, wild turkey, ruffed grouse, spruce grouse, gray catbird, brown thrasher, rufous-sided towhee, northern mockingbird, black-capped chickadee, red-cockaded woodpecker, starling, cardinal, scarlet tanager, Canada goose, herring gull, whimbrel, quail, and thrushes, and eastern bluebird.

The reproductive success of black bears has been particularly correlated to annual blueberry crops. Poor blueberry crops can limit black bear reproductive success as well as overall survival in some regions. Bear depredations such as damage to crops and beehives and livestock losses typically increase during poor berry years. (USDA FEIS, 1991)
