The ORI’s Research News on Boreal Owls The Boreal Owl Boreal Owl. Within North America, Boreal Owls were once thought to nest only in Canada. However, surveys in the 1980s and review of the historical literature suggested otherwise. Today, we know that this species is found throughout the west in high elevation spruce-fir forests from Alaska to New Mexico. There is also evidence they breed in northeastern Canada, and perhaps northern Maine. Like the Northern Saw-whet Owl, most breeding biology information comes from nest box studies. Measurements of Breeding Female Boreal Owls We share the same concerns about our Boreal Owl nest box study as those highlighted for Northern Saw-whet Owls. Although interesting, our data may not reflect natural distribution or other aspects of their biology (such as mating system), due to the artificial establishment of nest boxes. However, nest boxes are used with some predictability, and afford easy access for monitoring and data collection for specific questions, such as growth rates and plumage development. First Year Breeders Older (at least 2) Total Number Banded 9 18 27 Avg. Wing Chord (mm) 165 172 169 Avg. Tail Length (mm) 109 109 112 Avg.
