Guide to Boreal Birds
Intelligent, wary, virtually omnivorous, and with a high reproductive capacity, the American Crow is undoubtedly much more numerous than it was before the arrival of settlers. An opportunist in its feeding, the American Crow consumes a great variety of plant and animal food: seeds, garbage, insects, mice. Its nest-plundering is decried, but in orchards and fields it destroys many injurious insects such as grasshoppers and cutworms. However, the labeling of birds as either "harmful" or "useful" is misleading and antiquated. Crows do destroy many eggs and nestlings of woodland and meadow birds, but they also weed out the weak and feeble, and they alert the animals in a neighborhood when danger approaches.
