The donkey or ass is a domesticated member of the horse family.

Donkeys are adapted to marginal desert lands. Unlike wild and feral horses, wild donkeys in dry areas are solitary and do not form harems. Each adult donkey establishes a home range; breeding over a large area may be dominated by one jack.

The loud call or bray of the donkey, which typically lasts for twenty seconds and can be heard for over three kilometers, may help keep in contact with other donkeys over the wide spaces of the desert.

Donkeys have large ears, which may pick up more distant sounds, and may help cool the donkey's blood. Donkeys can defend themselves by biting, striking with the front hooves or kicking with the hind legs.
