Facts about Red Colobus Monkeys
- 09
Red colobus monkeys have a gestation period of approximately 165 days, among the longest of any primate relative to their body size.
- 08
Vocal communication in red colobus monkeys includes at least seven distinct alarm calls that specify predator type, allowing group members to mount appropriate defensive responses.
- 07
Groups of red colobus monkeys typically contain 15 to 80 individuals organized into stable subunits that forage and rest together throughout the day.
- 06
Leopards and crowned eagles are the primary predators of red colobus monkeys, with predation accounting for up to 15 percent of annual mortality in vulnerable populations.
- 05
A red colobus monkey's diet consists of approximately 90 percent unripe fruit and young leaves, making them highly selective foragers compared to other colobus species.
- 04
Infants of red colobus monkeys are born with white fur that gradually darkens to reddish-brown over their first six months of life.
- 03
Male red colobus monkeys lack canine teeth larger than females, making them among the least sexually dimorphic primates despite living in multi-male groups.
- 02
Specialized stomach chambers in red colobus monkeys ferment leaves similarly to ruminants, allowing them to digest tough vegetation that most primates cannot process.
- 01
These African primates inhabit only fragmented forest patches across West and Central Africa, with some populations numbering fewer than 500 individuals.
