A few of these colorful, errant strands add highlights to a dark furry crown, while punk-rock spikes of black fur edge the hairline. A pug nose with generous nostrils completes the facial features.įlaring out from either side of this monkey’s arresting face are long tufts of reddish-orange fur. of Hollywood fame (and we won’t deny the likeness), we prefer to liken this monkey’s hairless, wizened visage to that of the legendary vampire Nosferatu-except with dark pigmentation, save pale pink skin beneath almond-shaped brown eyes and surrounding the narrow lips. While some see a strong resemblance to the loveable alien E.T. Other colobus species are reported to have a lifespan of about 20 years in the wild. In contrast, males typically stay put within the safety of their group. Because they often migrate between groups, females expose themselves to dangers, including predator threats. Females experience a higher mortality rate when compared to males. Mortality rate decreases to 18 percent between 6 and 12 months of age but surges to 28 percent between 18 and 24 months of age-a direct result of chimpanzee predation. Not surprisingly, infants are the most vulnerable with a mortality rate of 30 percent from birth to 6 months of age. While lifespan for western red colobus monkeys is unknown, scientists have identified several factors known to impact the species’ mortality. As example, both male and female western colobus monkeys of Sierra Leone are the same size. Not all populations exhibit this sexual dimorphism, however. Males carry a bit more girth on their frames than females, weighing between 20 and 27 pounds (9.1–12.2 kg) females weigh between 15 and 20 pounds (6.8–9.1 kg). A long, nonprehensile tail adds another 25 to 30 inches (63–77 cm) to the body of both sexes. Head-to-body length for adult males is between 19.7 and 25 inches (50–63 cm) and between 17 and 25 inches (43–63 cm) for females. Current studies-and sightings-are necessary to confirm that Miss Waldron has not been ushered out of the world we share. But a grave possibility exists that this subspecies may be extinct. Decades-old evidence has allowed some wildlife biologists to express cautious optimism of this subspecies’ continued existence. Waldroni), might still be found in forestland between the Ehy Lagoon and Tanoe River of western Ghana. Temminckii), found in southwestern Senegal, the Gambia, much of Guinea-Bissau, and northwestern Guinea.
