Mating occurs from October through December. After a gestation of 120-140 days, a female gives birth to a single, precocious young. The young are born fully furred, with their eyes open, and are able to eat solid food on their first day of life. Nursing continues for eight weeks. Females are remarkable for the large number of ova they ovulate (around 300) during each estrus period.
