THE REPRODUCTIVE-BEHAVIOR OF GOLDEN MONKEYS IN CAPTIVITY (RHINOPITHECUS-ROXELLANA-ROXELLANA)

The reproductive behavior of two captive harem breeding groups of gold en monkeys was observed over one mating season and compared to non-sea sonal reproductive behavior. Observation of over two thousand sexual i nteractions suggests that 1) females were responsible for 95% of all s exual solicitations (preceptive behavior), of which the typical patter n was prostration, while males were responsible for only 5%; 2) 17% of female solicitations were interrupted by another female; 3) 52% of fe male solicitations resulted in mounting by males; 4) the frequencies o f solicitations and receipt of mounts and ejaculations varied greatly among females; 5) the frequency of ejaculations, the ratio of ejaculat ions to mountings, and ejaculation patterns were different between two males, and 6) the golden monkey is a seasonal breeding animal.
