Which mammals can hurt you

Official sources single out these mammals in Oregon, in their own words:

  • Cougar (mountain lion)

    Attacks on people are rare but have happened, including a fatal attack (ODFW). “Cougar attacks are rare but they have happened. Some have been fatal, such as a 2018 incident on Mt. Hood when a hiker was killed by a cougar.” Oregon Department of Fish and Wildlife

  • Black bear

    Never safe to approach. “In most cases, a bear will avoid human contact and attacks are uncommon. However, it is never safe to approach a bear.” Oregon Department of Fish and Wildlife

  • Striped skunk

    Striped skunk

    Can be infected with rabies (ODFW). “Striped skunks tend to be docile and unobtrusive; except during breeding season or when infected with rabies, they are not aggressive or belligerent.” Oregon Department of Fish and Wildlife

  • Gray wolf

    Attacks on humans are rare. “While coyote and wolf attacks on humans are rare, use caution, manage food and garbage safely, and leave dogs at home or keep them leashed and near you at all times.” Oregon Department of Fish and Wildlife

  • Coyote

How to report

What official sources say

Are there grizzly bears in Oregon?

No. ODFW: there are no grizzly bears in Oregon; any "brown" bear seen in Oregon is a black bear. Oregon has about 25,000 to 30,000 black bears. Oregon Department of Fish and Wildlife

“There are no grizzly bears in Oregon, so if you see a "brown" bear in Oregon, it is a black bear.”
