- Observations
In the wild, these animals have been observed to live up to 17 years [1133]. Evidence of reproductive senescence has been reported in females over 6 years of age [0048]. Annual survival has been reported to be 0.84 for adults [0748], but declines in animals older than six years to 46% at age 17. Both sexes show similar onset and rate of survival senescence [1205].
