Most wolves in the wild only live about three or four years, but one Yellowstone wolf has entered her 11th year – and just brought another litter of pups to the famous National Park.
Wolves were first reintroduced to Yellowstone nearly 20 years ago in 1995 and according to the National Parks Service, there are at least 124 wolves over 10 packs today. Some years, that number drops as low as 80, and wildlife officials expect older wolves to die, but this female keeps defying expectations.
