They are widespread in brushy areas from southern Canada to South America, predominantly east of the Rocky Mountains.
Cottontails feed at night, subsisting on a variety of green plants, barks, buds, and grasses.
Unlike the jackrabbit, which is actually a member of the hare family, cottontails are true rabbits. This distinction is important, as hares are born virtually self-sufficient, whereas rabbits are born hairless, blind, and helpless. In addition, hares tend to be larger and more muscular than rabbits. The cottontail is an essential element of the food chain, serving as prime prey for many predators. Cottontails are somewhat difficult to view, due to their swift and elusive nature.
