Many thanks to all who have generously responded to our end-of-the-year letter. A list of donors will appear in the March Leaves. "Alaska, America's Last Great Birding Adventure" Monday, February 21, at 7:30 PM First United Methodist Church 1551 Montgomery Drive Santa Rosa Longtime Madrone Audubon leaders and inveterate world travelers Betty Burridge and Diane and Bryant Hichwa took a birding and wildlife trip to Alaska in June, 2004. Join them for an illustrated armchair tour of Alaska's awe-inspiring wild areas. A preview from the participants: "We begin at Prudhoe Bay in Deadhorse, north of the Arctic Circle. The treeless coastal tundra has permafrost 2000 feet deep in winter but teems with wildlife in summer-caribou, arctic fox, muskoxen, and grizzlies share the plain with Rough-legged Hawks, Snow Buntings and eiders. We explore grizzly and Gyrfalcon territory in the high mountains of Denali. On the boat "Discovery" for the final leg, Prince William Sound in southern Alaska offers kittiwakes, puffins, dolphins, sea otters and glaciers galore." Betty Burridge is the editor of the Sonoma County Breeding Bird Atlas, published by Madrone Audubon in 1995. Bryant and Diane Hichwa are both past presidents of Madrone, and Diane has chaired the Madrone Conservation Committee since 1996. Coming in March: "Adaptations of Seabirds" with ACR Biologist Gwen Heistand. By MAS President Sylvan Eidelman On November 17 and 18, Joyce MacLaury, Veronica Bowers, and I participated in the California Audubon Assembly in Stockton. There were over 100 participants from 28 chapters in the state, as well as members of the board of directors of California Audubon. The opening speech was given by Glenn Olson, California Audubon's new Executive Director. Glenn is an enthusiastic and extremely competent individual with many years of Audubon experience, and we are lucky to have his leadership. Participants had a wide choice of workshops to attend: best practices for a chapter, fund raising, involvement in the political process, inspiring volunteers, and more. I was one of the presenters of a "Building Your Base" workshop, using my work with the Petaluma Wetlands Sanctuary as an example of a way to accomplish an environmental project and at the same time generate excitement and participation within a chapter. A goal of the Assembly was to choose a conservation agenda for the year 2005. There was a large menu to choose from, but we decided to concentrate on the following issues: defense of the Federal (and California's) Endangered Species Act; legislation to protect Important Bird Areas (IBAs); the passage of a 2006 state bond issue for conservation funding; support for the California Condor recovery effort; protection of critical bird habitat in the San Francisco Bay Delta and the Salton Sea; and the search for a way to protect birds from wind power and cell phone towers. No Audubon event would be complete without a birding opportunity, and we were lucky enough to go on a sunset field trip to view Sandhill Cranes flying in for the night at the Consumnes Preserve near Lodi. Joyce, Veronica and I would like to thank Madrone for sponsoring us at this conference, where we learned a lot and made valuable contacts with other California Audubon members. The last such statewide gathering took place four years ago; we are now hoping it will become an annual event. Shollenberger Park, Wednesday, November 24 Sacramento Valley Wildlife Refuges, December 1 and 2 Bolinas Lagoon, Thursday, December 16 Bodega Bay, Thursday, December 30 By Carol Orme, Birdathon Coordinator If you'd like to field a team this year, there is still time to do it! It's fun and a fine way to make a contribution to Madrone Audubon. How do I start, you ask? Find a friend or two and form a team, give yourselves an interesting team name, ask family, co-workers and acquaintances to sponsor your team, pick a date in February and enjoy a day of birding! Eight teams have made their plans and are ready to go. All are ready to do their part in support of Madrone's traditional fundraiser, our chapter's major source of funds for conservation and education efforts. The most seasoned teams, the Gray-headed Seersuckers and the Roadrunners, have been having fun and making a valuable contribution for as many years as we can remember. The Healdsburg Herons, the Surf Scooters and the Feather Questers have been providing consistent support to the chapter for almost a decade. The Taylors of Sonoma combine Elinor Taylor's regular Cornell Feederwatch Project with Birdathon every February. The Northern Pygmy Owls, a Pee Wee Audubon team under the leadership of Claire Shurvinton, will participate again this year. A recent addition to the Birdathon Team Roster is the team of Valerie Bowers and Phyllis Schmitt (still seeking the perfect name!). Sponsors are an integral part of each team's success and if you haven't been contacted to sponsor a team, please get in touch with any of the team members or call this year's Birdathon Coordinator, Carol Orme, at 546- 2324 to make the connection. In past years, we've had sponsors from as far away as Michigan, but our faithful members and their friends in the community help us to meet our goal every year. Why not contact a team captain and volunteer to be a sponsor? Just say, "Sign me up!" As we go to press, this year's teams are: ¨ FEATHER QUESTERS: Diane Hichwa and Karen Nagel in Sonoma County [From an article by Claire V. Gallagher, Ecologist, Sierra Nevada Research Center, November 22, 2004. The owl in question was brought to the Monte Rio firehouse last October and then taken to Santa Rosa Bird Rescue, where it was dead-on-arrival. It isn't known where it was first found or how it was injured. Article condensed and excerpted by Betty Burridge.] When I was invited to visit Bird Rescue to look at a mystery owl, either a Barred Owl (Strix varia) or a spotted-barred owl hybrid, my first thoughts were of dismay because of the already well-documented Barred Owl invasion of California. I promptly jumped to some incorrect assumptions. First of all, strictly using probabilities, the bird should be Barred, and not a hybrid. Historically, Barred Owls inhabited only eastern forests. They began to expand their range westward in the early 1900s. Recent decades have seen their southern movement along the west coast: a Barred Owl first appeared in Washington in 1973, in Oregon in 1979, and in California in the early 1980s. Barred Owls have been documented as far south as Nevada County, California (1998), and their range now almost entirely overlaps the range of the Northern Spotted Owl. Barred Owls are known for dispersing great distances (unlike their Spotted Owl relatives). In areas experiencing the very beginnings of a Barred Owl invasion, nomadic visiting owls, often called "floaters," form the front of the invasion wave (envision the Marines ). Secondly, since a Barred Owl (nicknamed "Darth Owl") had appeared in 2003 in Muir Woods, Marin County, it would be reasonable to expect that this would be a Barred Owl here in Sonoma County. Furthermore, as rare as it would be to find pure Barred Owl, the chances of this being a spotted-barred hybrid is ridiculously low. Another wrong assumption was that the bird was most likely a dispersing juvenile whose inexperience with the wilds had scheduled it a date with disaster. The timing of the bird's expiration-late October-would be typical of a dispersing juvenile. It goes without saying that I was quite shocked to see that the bird was, indeed, a spotted-barred owl hybrid, at least three years of age. It is most likely a hybrid of a Barred Owl and a Northern Spotted Owl (Strix occidentalis caurina). The patterning of the bird is an intriguing mix of Spotted and Barred Owl characteristics: Overall darkness of the brown pigment suggests Spotted Owl, while the extensive barring on the head and back suggests Barred. The breast displays a complex assortment of spotted and barred patterns, with prominent streaking (a la Barred Owl) on the belly. Spotted-barred hybrid owls are unique, both individually (no two hybrids look or sound the same) and collectively, with relatively little scientific data having been published about them. As they are rarely encountered in the field, their numbers are invariably too low for statistical analyses. We do know that hybrids typically occur in the early stages of a biological invasion-as Barred Owls infiltrate an area, the intruders will mate with Spotted Owls to give hybrid progeny. And as Barred Owl numbers increase, hybrid numbers will decrease; Barred Owls preferentially breed with their own species. A recent scientific paper (Kelly and Forsman, July 2004) compiled hybrid owl data from the Pacific Northwest and found that over a period of 26 years, only 47 hybrids have been observed. Interestingly, all confirmed spotted-barred hybrids were the result of male Spotted Owls mating with female Barred Owls; it is thought this could be because these males are as large as or larger than female Spotteds. Spotted-barred hybrids are also fertile, and can mate with Spotted or Barred Owls to create back-crossed hybrids. The hybrid given to Bird Rescue was quite a unique and exciting bird. Any opportunity to study a hybrid, dead or alive, is greatly valued. I certainly am very grateful for the opportunity to study the plumage of the bird before it moved on to serve science as part of the Cal Academy collection. By Kathy Angell New Local Members: New National Members: February Program Shollenberger Park Walk ( and Birdathon) Saturday, February 12, at 10 AM The first Pee Wee event of 2005 will be a walk at Shollenberger led by Claire Shurvinton.

Audubon Canyon Ranch Weekend Hosts Hosting at ACR on Madrone's scheduled Saturdays and Sundays is a wonderful way to support this special bird preserve and represent our chapter. Among the four local Audubon Chapters that support Audubon Canyon Ranch-Marin, Golden Gate, San Mateo and Madrone-I am proud to say that we have always been a leader in volunteer participation. Volunteers receive a brief orientation at 9:30 AM, then spend the day greeting visitors at the gate. During the day there is time to hike to the overlook to see the nesting egrets and herons, or just enjoy the preserve's patio while eating lunch. No experience required! I need to replenish my active host list for this spring's hosting. Many in our chapter are no longer unable to participate due to age, relocation or travel plans. Please call Janet at 526-5883 for exact dates and information.

By Joy Mander, CBC Compiler One hundred and forty-six birders entered the field on January 2 to conduct Madrone Audubon's 38th annual Christmas Bird Count. With cold and cloudy weather turning into rain, the conditions for counting were not optimal. In addition, first reports at the post-count potluck seemed discouraging-many leaders reported that they felt that they had seen fewer birds this year. However, the numbers of most birds counted this year are very similar to last year. You can see the total results for yourself in the data table on page . Only two areas saw a significant decrease in numbers of birds observed and many areas improved their numbers by several hundred! Last year we saw some huge flocks of Black Brant that were not present this time. You can see in the data table that we saw not one Northern Shoveler this year, but we did get an American Dipper for the first time in many years, and of course, the Harris's Sparrow is a new one for our count. Though the birding may not have been ideal, the involvement of our participants couldn't have been better. I'd like to thank the leaders: Sean Jeane, Doug Shaw, Jean Tonascia, Dan Noreen and Mary Rooney, Bill Payne, Karen Wagner, Ruth Rudesill, Ian Morrison, Mike Parmeter, Bill Lenarz, Richard Hurley, Sylvan Eidelman, Richard Merriss and Ken Wilson, Chris Wood, Mike Heffernon, Peter Leveque, Claire Shurvinton, Dennis Beale and Pam Conley, and Carolyn Johnson. Your dedication to the count and the hard work that you put into coordinating your areas is really appreciated. Thanks also to Peter Leveque for arranging the hall, and Virginia McDonagh and those who helped her also get a big thank you for managing the much appreciated potluck. I would also like to thank our new member Carol Benfell for her fine article in the January 3rd Press Democrat describing our annual Christmas Count and the changing patterns it tracks. Thanks also to Veronica Bowers, who announced Madrone's CBC at a Laguna Foundation meeting-I received a number of inquiries from their members eager to help with the count. I hope that those who joined our "regulars" had a positive experience and will join us again next year. The biggest thank you of all goes to the 127 counters who followed their leaders through that long day. I am so grateful to you all-there definitely would not be a count without you. I hope to see you all again next year. The 39th Christmas Bird Count will be held on New Year's Day, 2006. If you stay up late on New Year's Eve, consider going out for some owling! 36947 Individuals 40 Red-throated Loon Dan Nelson, 762-3811 Tundra Swan 11/13-14 Bodega Farm pond, Highway 12 DA, TE,
