Habitat: Evergreen and deciduous forest, second growth, mangroves and remnant forest. Distribution: West Honduras (perhaps Southern Belize) to West Ecuador. Natural History Notes: When approached the adult male may growl, bare teeth, shake branches and drop sticks on the observer. Uses all levels of the forest and ground to cross open areas, forest transit, to drink and to forage. Most active during the morning and evening and often sleeps at midday. Diet includes ripe fruit, buds, flowers, insects, small vertebrates and bird eggs. Group size ranges from 5 - 30, which disperses extensively to forage. Males defend a territory. Females tend to breed every 1 - 2 years. Females give birth to single or twinned offspring after 5 - 6 months gestation, and often during the dry season. Characteristics: Black with contrasting yellow-cream fur on head, chest and shoulders and a pink face. Tail often coiled at the tip.
