“The Future of Deep Forest Owls in California: A dilemma for conservation of Northern Spotted Owls”

In the last 50 to 100 years, the eastern Barred Owl has made its way to the western USA. Presumably helped by human landscape alteration, they now inhabit all of the range of the endangered Northern Spotted Owl and much of that of the California Spotted Owl. In recent years, evidence is mounting to suggest that Barred Owls have become a primary threat to Spotted Owls – they are fierce competitors, aggressive territory holders, faster reproducers, and have even been anecdotally reported to kill Spotted Owls. And they are spreading faster than ever. In this talk, Dumbacher will discuss the natural history and conservation concerns for both species, and discuss research and potential actions that are being considered by different management agencies.

Jack Dumbacher is curator of Birds and Mammals at the California Academy of Sciences and professor of Biology at San Francisco State University. He has been working on California Barred Owls since 2006. Both Northern Spotted Owls and Barred Owls are common species in Humboldt County.
