Mazama

A **brocket deer** is any species of deer in the genus ***Mazama***. Medium to small in size, and are found in the Yucatán Peninsula, Central and South America, and the island of Trinidad. Most species are primarily found in forests. They look similar to the African duikers and the Asian muntjacs, but they are not related. About 10 species of brocket deer are described.

The genus name _Mazama_ is derived from Nahuatl _mazame_, the plural of _mazatl_ "deer".

## Physical description and habitat

Depending on species,  brocket deer are small to medium-sized with stout bodies and large ears. The head-and-body length is , the shoulder height is , and the typical weight , though exceptionally large _M. americana_ specimens have weighed as much as . When present, the antlers are small, simple spikes. The pelage varies from reddish to brown to gray. Very roughly, the species can be divided into four groups based on size, color, and habitat (but not necessarily matching their phylogeny):

- _M. americana_ and _M. temama_ are usually found in forest. They are relatively large to medium brocket deer with a reddish to reddish-brown pelage. The head, neck, and legs are often grayish or blackish.
- _M. gouazoubira_, _M. nemorivaga_, and _M. pandora_ are found in forest, woodland, and shrubland. They are medium-sized with a brownish to grayish pelage and pale underparts.
- _M. nana_, _M. bricenii_, _M. chunyi_,  and _M. rufina_ are found in forest and high-altitude grassland (_M. nana_ in Atlantic forest; the remaining species in Andean cloud forest, elfin forest and páramo). They are medium to small in size, and the pelage is reddish. In most, a part of the legs and the upper part of the head are blackish or dark gray, but in _M. chunyi_, the foreparts and neck are also blackish or dark gray.
- _M. bororo_ is found in Atlantic forest in southeastern Brazil. In appearance, it is intermediate in appearance between _M. americana_ (first group) and _M. nana_ (third group).

## Behavior

In addition to being small and nocturnal, _Mazama_ species are shy and are thus rarely observed. They are found living alone or in mated pairs within their own small territory, the boundaries usually marked with urine, feces, or secretions from the eye glands. When threatened by predators (primarily the cougar and the jaguar), they use their knowledge of their territory to finding hiding places in nearby vegetation. As herbivores, their diet consists of leaves, fruits, and shoots.

## Reproduction

Mated pairs that live together remain monogamous. Single male deer usually mate with nearby females. When males compete for a mate, they fight by biting and stabbing with their short antlers. Brocket species that live in tropical areas have no fixed mating season, but those in temperate areas have a distinct rutting period in the autumn.

The gestation period is roughly 200–220 days and females bear only one fawn at a time. The young stay with the mother, keeping concealed until large enough to accompany her. They are normally weaned around six months of age and reach sexual maturity after a year.
