Taylor and Forsman (1976) reported recent range extensions of the Barred Owl (Strix varia) in western North America. Boxall and Stepney (1982) described the species’ distribution and status in Alberta. Shea (1974) summarized sightings, a photographic record, and several vocalization records of Barred Owls in western Montana but collected no specimens. Although published nesting records are not available, D. Flath (pers. comm.) stated that breeding is occasionally reported for the Blackfoot, Bitterroot, and Flathead River valleys (see also Skaaret et al. 1985). Marks et al. (1984) reported prey identified from 37 Barred Owl pellets from western Montana.
