|[Note Guidelines] Photographer's Note|
|The Red-tailed Monkey, Black-cheeked White-nosed Monkey, Red-tailed Guenon, Redtail Monkey, or Schmidt's Guenon (Cercopithecus ascanius) is a species of primate in the Cercopithecidae family. It is found in Angola, Cameroon, Central African Republic, Democratic Republic of the Congo, Kenya, Rwanda, Sudan, Tanzania, Uganda, Zambia, and possibly Burundi.|
This relatively small primate exhibits some sexual dimorphism in weight and body length. Males have an average mass of 4.1 kg and a length of approximately 46 cm. Redtail monkey females, in contrast, average 2.9 kg in mass and about 38 cm in length (Torstar Books 1984; Smuts et al. 1987).
Other than size differences, males and females of this species are very similar. The recognizable markings of adult redtail monkeys include a black face, bluish skin around the eyes, a white spot on the nose, and white cheek fur. The name 'redtail' comes from the chestnut-colored fur on the underside of the tail. The rest of the body is covered with a speckled brown coat and gray or black limbs, depending on the subspecies (Torstar Books 1984).
Redtail monkey infants have woolly gray fur at birth. Although they are born with a visible nose spot, young redtail monkeys have a brown tail and no cheek whiskers. As they mature, their markings begins to resemble those of adults (Kingdon, 1984). (Kingdon, 1984; Smuts et al., 1987; Torstar Books, 1984)
