Maxwell's duiker (Philantomba maxwellii) is a small antelope found in western Africa.

Description

Maxwell's duiker is an ungulate and a member of the family Bovidae. It grows to 30 in (76 cm) in length with a typical shoulder height of 14.5 to 16 in (37 to 41 cm), and weighs around 11 lb (5.0 kg), making it one of the smallest duikers. Its coat is either grey-brown or grey, with a white underbelly and white markings on the face. Pale bluish, nearly purple coats occur in rare cases.

Habitat and Distribution

Maxwell's duikers are found in the Western parts of Africa along with other species of duiker.[3] They inhabit lowland rainforests, such as lightly logged closed canopy forests and other locations like mixed farmlands and habitats with secondary vegetation, and are mostly found in forest areas subject to little human disturbance.

Diet

The Maxwell duiker's diet mostly consists of fruits, seeds, secondary vegetation and shrubs. Maxwell's duiker and other duikers present in the same geographical area were found to have similar diets. Diets are subject to seasonal changes, with a shift towards vegetation and parts of flowers at the beginning of winter.[3]

The animal's small size is reflected in its food choices. Due to its smaller mouth, body anatomy, and masseter muscle, it tends to concentrate on food items up to 3 (cm) in diameter, while larger species eat items up to 6 (cm) in diameter.[4]

Behavior

Maxwell's duiker has a preorbital gland known to be used for marking objects and members of the same species, especially by dominant males. It was one of the first animals observed using its preorbital gland for scent marking. It was shown that scent marking is also associated with individual recognition or social appeasement as male and females will often press these glands together on both sides of each other's faces.[5]

Reproduction and Lifespan

Calves are born mainly during the two dry seasons in Africa. Females birth a single calf once per year, after a gestation period of 120 days. Offspring usually weigh around 1/10 the weight of their mother and are similar in color to calves from other duiker species. Maxwell's duikers can survive up to 10 years in captivity.[6]
