Rabbits of New York Eastern Cottontail (Sylvilagus Floridanus), New England Cottontail (Silvilagus Transitionalis), Snowshoe Hare (Lepus Americanus)

Written by Kristi L. Sullivan and Megan Hilbert. 2014.* Description Cottontail rabbits are among the most common of our state’s mammals. Two species of cottontails exist in New York: the eastern cottontail, which was widely in- troduced in the early- to mid-1900s across many north- eastern states, and the New England cottontail, which is native to New York State. The eastern cottontail is common and thrives in fields, farms, and along forest edges, while the New England cottontail does best in dense thicket habitats. As a result of habitat loss and fragmentation, New England cottontails are declining in number, and have been replaced by eastern cottontails in many habitat patches. The characteristic for which the cottontail was Eastern Cottontail named is its short, brown and white, powder puff tail. The cottontail is slight of build compared to the Only the tail’s undersurface is white, but it is carried snowshoe hare.

Eastern Cottontail Rabbit
FACT SHEET Eastern Cottontail Rabbit COOL FACTS: Scientifi c name: Sylvilagus fl oridanus Average weight: 1.1 kg (2.5 lb) Average length: 45 cm long (17 inches) Speed: To escape predators, they can reach speeds up to 29 km/hr (19 mph) Lifespan: Average lifespan in the wild is 3 years. PHYSIOLOGY Several species of cottontails inhabit North America, but here in Eastern Ontario, the familiar “bunny rabbit” is the Eastern Cottontail. Their dense coat is a greyish-brown with black- tipped guard hairs. Perhaps the most familiar mark is the short white puffy tail (the cotton tail). They are best known for their white fl uffy tail but there coat is greyish brown. Their underside is usually white. They have excellent vision, sense of smell and hearing. The Eastern Cottontail has large brown eyes that are set high on its head. Each eye can move more than half a circle. Rabbits are generally quiet animals, although they may occasionally emit a few low grunts or squeals. Their primary form of communication is by stamping their hind feet. HABITAT/BEHAVIOUR Rabbits like living on the edge. Edge habitat, that is, where thickets, hedgerows, or treed areas meet old fi elds, agricultural lands or grassy meadows. Although they can be found in very open woodlands, this is not a typical habitat. Some form of escape cover is essential and rabbits never move too far away from brush piles, thickets, rock piles and burrows, which provide easy shelter from their many predators. Any landscape that supplies a combination of the above is considered good from a rabbit’s perspective.
