A threatened species of owl is losing a turf war in the Pacific Northwest.
Northern spotted owls are getting edged out of their already declining habitat by invading barred owls, a new study finds.
Researchers pored over 22 years of data from a study site in Oregon covering 386 square miles (1,000 square kilometers) where the habitats of the two species overlap. In this area, both owl species were more likely to abandon a neighborhood when their rival was present, the researchers found.
