Barred and Spotted Owls in the Western US: The Future of Deep Forest Owls
Speaker: Jack Dumbacher
January 12, 2017
7:00 p.m.

View Program Details

In the last 50 years, Barred Owls have colonized the west-coast states. They have increased their numbers significantly in Washington, Oregon, and more recently in California. New data suggests strongly that Barred Owls are critically involved in the continued decline of Northern Spotted Owls - even where habitat is being preserved and remains in good shape. US Fish and Wildlife is involved in a large study to understand the effects of the two owls on one another and to plot the fate of the Northern Spotted Owl under a variety of scenarios. Dumbacher's talk will discuss the current situation, the data that has been collected thus far, and talk about management options that are being discussed to save the Spotted Owl from extinction.

Jack earned his PhD at the University of Chicago, and worked as a Molecular Ecologist and Evolutionary Biologist at Smithsonian Institution before moving to the Bay Area in 2003. He is currently the Curator of Birds and Mammals at the California Academy of Sciences.

Sunda – A Land of Birds, Beasts and Dragons

20,000 years ago the lands that make up Malaysia, Indonesia and Singapore were all interconnected in the area geologists call Sunda. As glaciers melted and the sea level rose, islands like Borneo, Bali and Komodo were separated from the mainland of Asia, where the Malaysian peninsula is today. Alfred Russel Wallace explored this area in the 19th century when he independently developed the concept of evolution by natural selection made famous by Darwin. While reviewing many of the avian families of the area, we'll touch on some of the other forest creatures found here, the importance of islands to evolution, and the impact of the palm oil industry to tropical forests.

Bob trained as a chemist and worked for Chevron for 33 years. He's taught birding classes in the San Francisco Bay Area for over 20 years, and is a member of Golden Gate Audubon's Adult Education Committee. Bob loves to travel, and is an award-winning photographer, focusing on birds.

Cave Creek Canyon and the Chiricahua Mountains are famed for the presence of Elegant Trogon, Red-faced Warbler, Painted Redstart, Mexican Chickadee and the beauty of the sky islands of southeastern Arizona. From our base at the charming Cave Creek Ranch, we'll explore the varied habitats surrounded by this enchanting mountain range. Let's join Bob for a 5-day tour in 1 hour more or less to seek all of the area's specialty birds at one of North America's premier birding destinations.

Bob Power taught Introduction to Birding at Palo Alto Adult School for seven years, has been a day-leader for the GGRO's HawkWatch program for the past 13 years, and was the lead field seminar leader for the Santa Clara Valley Audubon Society for 10 years, leading and co-leading both domestic and international birding eco-tours.
