The oldest wolf in Yellowstone National Park, known as Wolf 907, gave birth to another litter of pups this spring.
The three pups are now about 4 weeks old and have started to crawl around. Wolf 907's current den is visible from the roadway.“We know of at least five wolves that we’ve captured and radio-collared that are her direct offspring,” she added.“She has now lived almost four times longer than the average wolf. On average they will only live to about 3 or 4 years old,” Cassidy said. “We've only recorded two that have made it to 12 years old,” she added.
“It happened at some point between the time she was 10 months old and 4 years old. And we’re not sure what happened,” Cassidy said. “It doesn't seem to hold her back at all.” “It's always some kind of really dramatic kind of death. About half of them die when two packs fight each other over territory. They will also die while they are hunting large prey like an elk or bison, they might get kicked or gored,” Cassidy said.“They can get enough experience that being successful is something that they then teach the younger packmates,” said Cassidy.
