(Portland, OR) -- An arctic fox that was caught in Portland's Willamette Park won't be returned to the wild. Arctic foxes naturally roam in Greenland, Canada, and Alaska. It's likely this arctic fox was illegally living captive in Portland. The Bird Alliance of Oregon said the animal had no fear of people. It's in good health, but can't be released into the wild, because it wouldn't survive. The Bird Alliance is working with the Oregon Department of Agriculture to locate an accredited facility where it can live.
