Conservation Status: Least Concern.


At dawn and dusk in the mountainous regions of the western United States, the Mountain Cottontail forages for sagebrush, western juniper, and grasses, almost always close to cover. As befits a rabbit that lives where it gets very cold, its feet are covered with long, dense hair, and its rather short ears are furry inside. Young rabbits are born blind and hairless, in nests lined with grass and the mother's fur, in litters of four to eight. (In contrast, hares are born fully furred and ready to hop.) A female Mountain Cottontail may produce five litters each year.

Also known as:

Nuttall's Cottontail

Average: 362 mm
