Welcome to the Owl Research Institute - Charlo, Montana

owl eyes

For more than 25 years, the Owl Research Institute (ORI) has been dedicated to scientific research of owls — their ecology, natural history, and habitat relationships.

Because owls are chronically under-researched and poorly understood, we strive to provide high-quality, long-term studies of owls, and use our findings to promote conservation.

Here are some of our successes:

  • Sustaining studies of Long-Eared (since 1982), Snowy Owls (1992), and prey species (1992)
  • Assessing populations and habitats of Montana’s 15-some owl species
  • Disseminating our findings with more than 80 scientific publications
  • Collaborating with federal, state, and local groups to facilitate wildlife and habitat protection
  • Teaching natural history, through classes and conferences, to thousands of people each year.

Ninepipes Research CenterOur research station, the Ninepipes Center, is situated in the Mission Valley of western Montana. Surrounded by wildlife refuges, grasslands, and wetlands, the area is home to Grizzly Bears, American Bison, and record-setting numbers of raptors.

The Owl Research Institute is a non-profit, 501(c)3, tax-exempt organization (EIN 81-0453479), and primarily funded by grants from foundations, corporations, and individuals. Here are some things you can do to help us achieve our mission of wildlife conservation through research and education:

  • Become a member of the Owl Research Institute
  • Take part in one of our wildlife tours
  • Come to our annual fundraiser, the Hat Party
  • Participate in one of our volunteer work projects
  • Get involved in one of our research programs!
