Roe Deer, Western Roe Deer

Maximum longevity: 17.5 years (captivity) Observations: Young females have an over 90% survival in the wild, though an increased mortality with age has been reported for both males and females after about 8 years of age (Loison et al. 1999). These animals may live up to 15 years in the wild (Bernhard Grzimek 1990). One wild born female was about 17.5 years when she died in captivity (Richard Weigl 2005). The implantation can be delayed from 2 to 5.5 months, so the total gestation time can last from 122 to 305 days.
