Deer is a hove, cud-chewing, mammal with a four-chambered stomach, found on almost all continents except Australia and Antarctica, Africa has only one native
species, the Red Deer, confined to the Atlas Mountains in the northwest of the continent.
Different species of deer live in different habitats. The habitats range from cold tundra to the wet tropical rainforests.
Deer weights generally range from 30 to 250 kilograms, though the Northern Pudu averages 10 kilograms and the moose averages 431 kilograms .
Male deer of all species (except the Chinese water deer) and female reindeer grow and shed new antlers each year. Deer generally have agile, compact bodies and long powerful
legs. Deer are also excellent jumpers, fast runners and swimmers.
Nearly all deer have a facial gland in front of each eye. The gland contains a strongly scented pheromone, used to mark its home range. Bucks of a wide range
of species open these glands wide when angry or excited. Deer also have a sufficiently good night vision.
Deer are selective feeders. They are usually browsers, and primarily feed on leaves, lichen, grass, shoots and berries.
For most deer in modern English usage, the male is called a "buck" and the female is a "doe", but the terms vary with dialect, and
especially according to the size of the species.
For many larger deer the male is a "stag", while for other larger deer the same words are used as for cattle: "bull" and
"cow". The male Red Deer is a "hart", and the female is a "hind".
Terms for young deer vary similarly, with that of most being called a "fawn" and that of the larger species "calf"; young of the smallest
kinds may be a kid. A group of deer of any kind is a "herd".
