Reproduction

Orangutan breeding strategy is based on raising a few high-quality, well-cared for young rather than mass production with high mortality.

Courtship

Sexually receptive females seek out and solicit mature, flanged males (males with cheek pads). During this time, females are attracted to the long call of males. Refer to Vocal Communication section for more information on long calls.

Male and female orangutans stay together only for a few days during periods of sexual receptivity. Males leave once the females become pregnant.

The orangutan pair will travel together, share food, and remain close together during the brief courtship period.
