Taxonomy: Strix acadica J. F. Gmelin, 1788, Nova Scotia.
Possibly forms superspecies with A. ridgwayi, although ranges appear to overlap in S Mexico (with apparent hybridization); perhaps conspecific with latter; further study needed. Proposed race brodkorbi from Sierra Madre in Oaxaca based on a single juvenile specimen. Two subspecies recognized.
