Abstract: | The reproductive behavior of two captive harem breeding groups of golden monkeys was observed over one mating season and compared
to non-seasonal reproductive behavior. Observation of over two thousand sexual interactions suggests that 1) females were
responsible for 95% of all sexual solicitations (proceptive behavior), of which the typical pattern was prostration, while
males were responsible for only 5%; 2) 17% of female solicitations were interrupted by another female; 3) 52% of female solicitations
resulted in mounting by males; 4) the frequencies of solicitations and receipt of mounts and ejaculations varied greatly among
females; 5) the frequency of ejaculations, the ratio of ejaculations to mountings, and ejaculation patterns were different
between two males, and 6) the golden monkey is a seasonal breeding animal. |
