How long do pandas stay pregnant for?
The gestation period of the panda varies somewhat by the environment in which it lives. In the wild it can range from 129 to 159 days, with the average period settling around 148 days. Pandas in captivity have a wider range, lasting from as little as 84 days, to as many as 160, with the average being about 122 days. The female panda can begin having babies as early as 4 to 5 years old, but generally stops by around 20 years of age.
