This 1st summary of the barred owl (Strix varia) colonization of Montana was constructed from a review of the literature. We believe that previous reports of spotted owls (S. occidentalis) in Montana were most likely mis-identifications of barred owls. Evidence suggests that Montana was the 1st state where barred owls entered the northwestern United States, which occurred approximately 75 years ago in the early to mid-1920's. These owls appear to have originated from Canada. The historic distribution of barred owls in far eastern Montana is unlikely, however. At least 87 confirmed records of ≥1 barred owl now exist in Montana, and it appears likely this species will continue to colonize both north to south and east to west.
