Muntjac deer are small deer with distinctive antlers, small tusks and the ability to “bark” which gives them an alternate name of barking deer. Adults are small and reddish, males having small antlers and pronounced ridges on the face, while females have much smaller ridges. Fawns are pale and spotted. They are omnivorous, which is unusual for deer. They do eat a lot of vegetation, such as foliage and fruit, but may also eat eggs and very small animals. In their native China, food is available all year round, allowing them to breed year round. This results in males being aggressive and territorial throughout the year. Males and females are mostly solitary with their own territories.
