Hares
Hares do not bear their young below ground in a burrow as do other leporids, but rather in a shallow depression or flattened nest of grass called a form. Young hares are adapted to the lack of physical protection, relative to that afforded by a burrow, by being born fully furred and with eyes open. They are hence precocial, and are able to fend for themselves soon after birth. By contrast, the related rabbits and cottontail rabbits are altricial, having young that are born blind and hairless.
