Abstract

During the winter, large birds such as crows and hawks may compete at animal carcasses for food. Carcasses were placed along county roads to measure competition. American crows in a flock of 20–30 were more likely to out-compete red-tailed hawks at road kills than were crows in flocks of 4–6 birds.
