Few Boreal Owls were detected in the early years of this effort.

During its breeding cycle, this owl requires three distinct types of microhabitat within upland (fire-dependent forest and mesic hardwood forest) and lowland (forested rich peatland) forest types. In light of the rarity, very limited distribution, and highly specific habitat requirements (and continuing loss of this habitat) of this species in Minnesota, in 2013 the Boreal Owl was designated a species of special concern. It is mysterious in both appearance and name, Strix nebulosa. This is a rare bird of the North Country, the Great Gray Owl.

The Boreal Owl (Aegolius funereus) is a forest-dwelling owl that breeds in boreal and subalpine forests in North America and Eurasia. Potential Boreal Owl habitat in the BWCAW is susceptible to large-scale natural disturbances such as fires and wind-throw events. Eggs hatch asynchronously (i.e., in the order laid), after approximately four weeks. However, simply providing artificial nest boxes for Boreal Owls is not enough, as nest boxes in Minnesota have shown low occupancy rates; therefore, other habitat parameters are also required. The winter 2004-2005 influx of northern owls: an overview. That same winter, only three Boreal Owls were noted.

However, females may desert their first brood around fledging, particularly in good food years, presumably in order to pair with another male and raise a second brood. The roadless nature of the BWCAW makes status surveys logistically difficult due to challenging access during the optimal survey period (early spring), when terrain is often snow-covered (sometimes to significant depths) and waterways are not ice-free. Data collected during 1987-1990 were combined with the 2000-2001 data and all sampling methods were standardized. A final project report submitted to the Minnesota Department of Natural Resources.

These owls eat mainly rodents, and they feed mainly at night. Typically these cavity trees are located within older mixed coniferous - deciduous forest stands rather than purely deciduous forest (since song perch trees, typically conifers, must be nearby). This is thought to be related to population fluctuations in prey in which much higher than normal numbers of owls move beyond their typical winter range. Initiated in 2005, the Western Great Lakes Region Owl Survey, led by the University of Minnesota Duluth's Natural Resources Research Institute (NRRI) and Hawk Ridge Bird Observatory (HRBO), has provided data on owl abundance and distribution in Minnesota and Wisconsin (Grosshuesch and Brady 2014).
