- •
We used changes in natal coat to assess early infant development in wild colobus.
- •
Infant males, at higher risk of infanticide, changed coats faster than infant females.
- •
Infants changed coats faster in multimale groups (higher risk) than in unimale groups.
- •
Infanticide pressure, not predation or feeding competition, affected development.
- •
Accelerating development is a strategy of mothers and infants to avoid infanticide.
