Guide
A rather mysterious owl of dense northern woodlands. Except when calling at night in very early spring, it is easily overlooked. Until the 1970s it was not known to breed anywhere south of Canada; recent explorations have shown that it is a resident in many mountain ranges in the western United States, nesting in forest at the highest elevations. In the northeast, winter invasions sometimes bring a few Boreal Owls south to areas frequented by birders.
