Reproduction in the wild
There is only one opportunity per year for the female panda to mate, usually during spring time. The female panda has a window of between two and three days to conceive. The length of the giant panda’s gestation period is not exact, it can range from 82 to 225 days (approx. 3-8 months) from mating to birth due to delayed implantation.
Giant pandas usually rear just one young every two to three years. A female may have about seven cubs in her lifetime.
Sometimes giant pandas give birth to twins but the mother usually abandons the weaker cub and concentrates her energy on rearing one cub.
