Reeves's muntjac (Muntiacus reevesi; ), also known as the Chinese muntjac, is a muntjac species found widely in southeastern China (from Gansu to Yunnan) and Taiwan. It has also been introduced in the United Kingdom, Ireland, the Netherlands, Belgium, and Japan. It takes its name from John Reeves, a naturalist employed by the British East India Company in the 19th century. Description Reeves's muntjac grows to high at the shoulder and in length, plus a short tail up to long. It weighs between when fully grown. It is reddish-brown in appearance with striped markings on its face. The belly is creamy-white, with lighter fur extending to the neck, chin, and the underside of the tail. The males have short antlers, usually or less, and long upper canines (tusks), usually about long. Females have bony lumps on their foreheads and localized black spots. The Taiwanese subspecies (M. r. micrurus), commonly known as the Formosan Reeves's muntjac, is darker than other subspecies. Behavior Reeves's muntjac feeds on herbs, blossoms, succulent shoots, fungi, berries, grasses, and nuts, and has also been reported to eat tree bark. Eggs and carrion are eaten opportunistically. It is also called the barking deer due to its distinctive barking sound, though this name is also used for other species of muntjacs. The barking sound is common during mating or when provoked. Its preferred habitats are forest and shrubland. It is a solitary and crepuscular animal. Both males and females defend small territories that they mark with preorbital gland secretions that are thought to be pheromonal in nature. When fighting, males first use their antlers to push enemies off balance so they can wound them with their upper canine teeth. Reproduction Female muntjacs (known as "does") become sexually mature within the first year of life. Mating occurs throughout the year. Their gestation period lasts from 209 to 220 days. Females limit the number of mating bouts, though time between successive bouts is determined by males (known as "bucks"). Distribution It is found widely in southeastern China (from Gansu to Yunnan) and Taiwan. It has also been introduced in several other regions. Continental Europe It has been introduced in Belgium and seen in the Netherlands. In Europe, this species is included since 2016 in the list of Invasive Alien Species of Union concern (the Union list). This implies that this species cannot be imported, bred, transported, commercialized, or intentionally released
