Species Code: AEAC
Metadata (Data about data or how the map was made)
This species is uncommon to fairly common in forests at low and moderate elevations throughout the state. They are found in all forest types. They are also found nesting locally in riparian vegetation along the upper rim of the Columbia Basin, and foraging in nearby sagebrush habitats. It is rare in very high forest zones, such as the Sub-alpine Fir, Whitebark Pine, and Alpine/Parkland zones. This species requires cavities for nesting.
Good habitat in the core areas of use included all forests in all forested zones below the Sub-alpine Fir zone and forested habitat in steppe zones at the perimeter of the Basin. Forests in the Sub-alpine Fir, Mountain Hemlock, and Alpine/Parkland zones were peripheral areas of use.
Washington breeders represent the widespread subspecies A. a. acadicus. Contrary to some reports, the Northern Saw-whet Owl breeds readily in a variety of forest types. It occurs in virtually every forested zone below the Sub-alpine zone throughout the state, and is found in both coniferous and hardwood woodlands. At high elevations where it is absent, it is replaced by the Boreal Owl. Researchers reported a nest in riparian growth near Dayton in Columbia County on March 26, 1948. Northern Saw-whet Owls are reported to be common breeders throughout the Blue Mountains. As for many owls, they are undoubtedly more common than indicated by the sparse BBA data because of low detection frequency. This owl is most vocal in late winter, when much of its range is inaccessible because of snow cover.
