Brocket Deer are a group of deer species of the Mazama genus found in South America and the Yucatan Peninsula. They are small in size and dwell primarily in forests. They are similar to the Duiker species, but unrelated. There are seven known species of Brocket Deer, all of them closely related.
The Mazama species are all similar in appearance, although the size may vary. They have small rounded bodies, ranging from 2.3 to 4.5 ft (70 to 140 cm) in length, and usually have a light or dark brown coloration. Weight ranges from 17 to 66 pounds (8 to 30 kg). The antlers are short and are shed very infrequently.
In addition to being nocturnal and their small size, Mazama are shy and 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 approached by predators (pumas and jaguars are their primary threats), being knowledgeable about their territory, they will hide in nearby vegetation. As herbivores, their diet consists of leaves, fruits, and shoots found within their territory.
Mated pairs who live together remain monogamous. Single male deer will usually mate with nearby females. When males compete for a mate, they fight by biting and stabbing with their short horns. 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 only bear one doe at a time. The young stay with the mother, keeping concealed until large enough to accompany her. They are normally weaned at about six months of age and reach sexual maturity after a year.
