THE ANIMAL FILES

Wedge-capped capuchin

Cebus olivaceus

A dark wedge on the head, and a forest life shared with helpers.

The wedge-capped capuchin takes its English name from the dark triangle running back from between the eyes. Beyond the cap, this monkey combines active canopy travel, a mixed diet and infant care that can involve females other than the mother.[1]

Running and jumping overhead

Comparisons with tufted capuchins found more running and jumping in wedge-capped capuchins, alongside relatively longer limbs, especially the hindlimbs. The finding concerns comparative movement patterns, not a claim that every journey uses the same gait.[1]

Looking for more than fruit

Ripe fruit, including figs, forms much of the plant diet, while insects and other small animals contribute animal food. Foraging differs with age, sex and season; young animals do not necessarily use resources in the same proportions as adults.[1]

Care beyond the mother

Young infants initially depend on their mothers, after which other females increasingly help with carrying and nursing. Siblings participate strongly. Such shared care changes who handles the infant as it develops.[1]

A COMMON MIX-UP

Does shared care mean the mother never matters?

No. Early care is concentrated on the mother; help from other females increases later. Timing is central to the pattern.[1]

TRY A LITTLE REASONING

Why distinguish infant and adult foraging observations?

Reveal the explanation

Age-related differences in the use of plant and animal foods mean one age group may not represent the whole troop.[1]
