Taxonomic Comments
Formerly treated as a subgenus within Otus (Marshall and King in Amadon and Bull 1988), but mitochondrial DNA and vocal differences with Old World species indicate that generic status is warranted (Konig et al. 1999).

Prior to 1982 regarded as conspecific with O. ASIO. Populations in northwestern Mexico have been treated as separate species (O. VINACEUS) by some authors. Mixed pairs and overlap of ASIO and KENNICOTTII in Colorado and Texas is attributed to long-distance dispersal in marginally poor habitat. Sympatry without interbreeding with ASIO reported for western Edwards Plateau (Dixon 1989).

Threat ImpactHigh
Range Extent20,000-2,500,000 square km (about 8000-1,000,000 square miles)
Number of Occurrences81 to >300
Rank Reasons
Still widespread; population probably stable in many areas, probably declining in others. Threatened by habitat loss and/or degradation, particularly the loss of riparian forests and woodlands.
Range Extent Comments
RESIDENT: from south-coastal and southeastern Alaska, coastal and southern British Columbia, northern Idaho, western Montana, southeastern Colorado and extreme western Oklahoma south to southern Baja California, northern Sinaloa, in Mexican highlands to Distrito Federal, and to western Texas (AOU 1998, Cannings and Angell 2001). Apparently has expanded north into southern Alberta.
Threat Impact Comments
Primary threat is loss or degradation of habitat. Closely linked to riparian forests and woodlands over much of its range, and this is often the first habitat in any given area to be altered, especially in the dry southwest (Cannings and Angell 2001). On coastal British Columbia, may be threatened by largescale logging (Chaundy-Smart 2002). In the Pacific Northwest, traditional territories have been abandoned coincident with the arrival of Barred Owls in an area (Cannings and Angell 2001).
Ecology & Habitat

Habitat

Woodland, especially broadleaf (e.g. oak) and riparian woodland, and scrub (Subtropical and Temperate zones) (AOU 1983). Also moist coniferous forest and woodland on northwest coast. Usually found at lower elevations, where in southwest range overlaps with Whiskered Screech-owl (National Geographic Society 1983).

Nests in natural tree cavity or an abandoned woodpecker hole, including holes in saguaro cactus. Readily nest in nest boxes.

Ecology

In central Idaho, home ranges of 2 radio-tagged birds reported as 3-9 ha and 29-58 ha based on 75% and 95% contour intervals, respectively. Distance between adjacent pairs ranges from ca. 50 up to a few hundred meters (see Johnsgard 1988).

Reproduction

Clutch size averages 3-4. Incubation about 26 days.
