One of the wolves at the Menominee Park Zoo in Oshkosh passed away.
Sienna was a 16-year-old gray wolf. She came to the zoo in 2014 along with three other wolves from the Wildlife Science Center north of the Twin Cities in Minnesota.
Assistant Parks Director Chad Dallman says Sienna was the lead wolf in the pack. He says she wasn’t big in stature, but her personality and attitude reflected the dominance she had with the pack.
Dallman says they had to put Sienna down because she was suffering from kidney failure. Her brother, Thunder, is the only gray wolf left at the zoo.
The typical life span of a wolf in the wild is six to eight years.
