Biologists recommend urgent action to protect California spotted owls
(PHYSorg.com Biology)

In the Pacific Northwest, the range expansion of Barred Owls has contributed to a conservation crisis for Northern Spotted Owls, which are being displaced from their old-growth forest habitat. How will this interaction between species play out in the Sierra Nevada, where Barred Owls are just starting to move into the range of the California Spotted Owl? New research published in The Condor: Ornithological Applications suggests that wildlife managers may still be able to head off similar problems in critical areas of the Golden State-if they act now.
