Males make up 56% of the population and females form 44%.

In some species, males and females form lifelong pair bonds.

These females may form new groups with subordinate males.

After the rut, females form large herds of up to 50 individuals.

The females form groups of five to twelve animals, with four generations of young in the group.

A female will often form a long-lasting social relationship with a male in her troop, known as a "friendship".

A male and female will form a breeding pair.

The females within a harem form a team in which there is much mutual support for one another.

In summer, males dwell alone, but females form a colony that is made of 10-80 adults.

A male usually never sees his mother again, but females sometimes come back with their own fawns and form small herds.
