Free-ranging mantled howling monkey (A. palliata Gray) females experienced a regular estrus cycle averaging 16.3 days, demonstrated sexual skin changes, and participated in multiple matings before becoming pregnant. Gestation averaged 186 days. The average interval between births was 22.5 mo. Sexual maturity occurred at approximately 36 and 42 mo. for females and males, respectively. Female age at 1st birth was about 3 1/2 yr. Birth were scattered during some years and clustered during others. The age, rank and parity of the females affected infant survival. More female than male infants survived to 1 yr of age. Increased population size was the result of immigration rather than births.
