Northern spotted owl threats
Roberts, and D. Other prey species include deer mice, tree voles, gophers, and snowshoe hares. The USFWS previously reviewed the status of the northern spotted owl in , and but found it did not warrant listing as either threatened or endangered. Logging in national forests containing the northern spotted owl was stopped by court order in Allen, S. Hicke, J. Franklin, G. Martin, and W. Owls Scott Anderson Burrowing owls are so named because they live underground in burrows that have been dug out by small mammals like ground squirrels and prairie dogs. Reasons for Decline Prior to the listing of the northern spotted owl, timber harvesting and land conversions resulted in the loss of owl habitat. WDFW participates on both of these teams. Although it is often considered to be a medium-sized owl, the northern spotted owl ranks among the largest in North America and lives in old-growth forests. The case for active management of dry forest types in eastern Washington: perpetuating and creating old forest structures and functions.
Carlson, L. Fun Fact Northern spotted owls are an indicator species, which means their presence in old-growth forests indicates a healthy ecosystem.
Geological Service Northwest Climate Science Center and other partners will evaluate potential effects of climate and land management on future vegetation structure and how these changes might influence spotted owls in coastal Washington.

Their flight pattern is distinct, involving a series of rapid wingbeats interspersed with gliding flight.
Spotted owls form long-term pair bonds divorce is an uncommon occurrence and remain in the same geographical areas year after year. Forsman, A. No more than 2, breeding pairs of northern spotted owls are believed to remain in the United States today.

Journal of Raptor Research Habitat Northern spotted owls live in forests characterized by dense canopy of mature and old-growth trees, abundant logs, standing snags, and live trees with broken tops. Sovern, C. Franklin, D. Nichols, J.
They are threatened by loss of habitat and logging, climate change and competition with increasing barred owl populations. Typically, forests do not attain these characteristics until they are at least to years old. Nests are often constructed in snags that have hollows large enough for the owls.
