There has been much debate over the classification of Glaucidium gnoma californicum. Some experts now believe that these G. gnoma californicum deserves specific status as G. californicum, but the taxonomy of the genus Glaucidium is controversial. Evidence used in support of their specific status include their vocalizations. Because owls in general are primarily nocturnal, or active at dusk and night, their physical appearance and plumage patterns are believed to be less important than their calls and songs (Heidrich et al. 1995). Glaucidium gnoma californicum, unlike other G. gnoma populations, primarily hunt during the day. Glaucidium gnoma resides on the west coast of North America (extending from Canada, down to Central America) (Holt 2000), Glaucidium gnoma californicum inhabits a more compact region on the west coast, through the Rocky Mountains - from southern Alaska to southern California (Owl Pages 2000).
