PRBO Conservation Science By Mary Edith Moore At a recent Petaluma Wetlands Alliance (PWA) public meeting, Ellie Cohen, Executive Director of PRBO Conservation Science, presented the following overview of the organization and how it would interface with the PWA and the Petaluma community. Change was on the horizon for the Point Reyes Bird Observatory (PRBO), founded in 1965 at Point Reyes and staffed with a half-time biologist. This non-profit organization, dedicated to conserving birds, other wildlife and ecosystems through innovative scientific research and outreach, has grown exponentially. The growth rate has been 17% per year for the past five years with a 2005 budget of $6.2 million. Personnel have increased to 120 staff and seasonal biologists, 70-80 interns annually, and 12 education, policy and support staff. No longer is research confined to Point Reyes, but sites are located throughout western North America as far north as Alaska, south to Mexico and Central America, across the California Current and the northern Pacific to Japan, and in Antarctica. To recognize and embrace all these sites, about a year ago a new name was chosen for the organization, PRBO Conservation Science. Birds are great indicators of an ecosystem's health. Studying bird ecology (bird productivity, life history, diet, etc. as well as habitat features that lead to successful reproduction and a continuation of their population) helps to evaluate and guide management in making the best decision to conserve the most biodiversity. The Fish and Wildlife Service says that nature watching and all that it entails is equal to a Fortune 500 company, a multibillion-dollar industry in the United States. Ellie said we have a lot of clout, and we should use it to conserve more. PRBO's basic strategy includes long-term population studies, an ecosystem approach, partnerships, adaptive conservation planning, training, and outreach. Long-term data can show trends of what is happening to species, what can be done to restore species population, and whether the changes are due to nature or humans. Ecosystem approach means looking at common, threatened, and endangered species and their habitat features. PRBO itself manages only a few habitats, but mainly provides scientific data to wildlife habitat managers so they can do a better job. Adaptive conservation planning is developing a plan, implementing the plan to see if it works, and then making appropriate changes to improve results. One of the advantages of the training and outreach programs for interns and professionals is to get the latest in conservation science into their hands so they can more quickly improve habitat conditions. The threat to wildlife and ecosystems will not decline soon, and the need to measure the success of conservation programs and investments will keep growing for several decades-a need that PRBO can help meet. In April 2006, PRBO will relocate their current headquarters from Audubon Canyon Ranch off Bolinas Lagoon to the office complex next to Shollenberger Park where they will own a 20,000-square-foot office condominium in a new 36,000-square-foot building. To help with the cost of the new headquarters, last week the Packard Foundation gave PRBO one million dollars toward their campaign goal of 8.3 million. The Palomarin Field Station at the southern end of Point Reyes National Seashore, site of PRBO's first headquarters, will continue as a training/education facility and a center for PRBO's landbird studies. Because of the lack of office space and outdated communication technology, huge amounts of data are sitting in computers, waiting to be analyzed. The new headquarters will have cutting-edge communications technology, a wet lab, a visitor center, a resource library, and a presentation room for science lectures from PRBO scientists. The presentation room will be available to the PWA for meetings. PRBO's Education Program will expand its workshops for teachers, bird walks, and outreach with kids from this new location. Ellie said PRBO would like to explore starting long-term surveys in Gray's Marsh. She asked for and took suggestions on how PRBO could work with the PWA and the community on issues benefiting the wetlands. Both groups have a strong desire to collaborate on issues of education in and stewardship of the Petaluma wetlands. PWA looks forward to this new partnership in overseeing our wetlands. (see www.prbo.org) "Mayacamas: Vegetative Recovery Following the Labor Day Fire of 2004" First United Methodist Church 1551 Montgomery Drive, Santa Rosa Peter Leveque and his grandson Gus Eichhorn made numerous
trips to the Mayacamas Mountains Sanctuary during the 2004/2005
school year. This endeavor was the result Fortunately for these two scientists, a very wet winter and spring followed the geysers fire. The vegetation took hold, and each trip was clothed in an eagerness to discover and document the growth which had taken place since their last visit. No doubt, there's going to be much to show and tell. At last the T-shirts and caps with the Audubon logo have arrived and will be on sale, $12 each, at the November 21 members' meeting. Get yours and spread the word. By Veronica Bowers Without looking at the calendar or observing the departure of our summer visitors and the change in the light, I know autumn is near when the Golden-crowned and White-crowned Sparrows and the Red-shafted Flicker arrive in our yard on or around September 18th. Like clockwork, on the morning of September 17th, I heard the loud, drawn-out "keough keough" call of a Flicker at the top of a Douglas Fir snag along our driveway. In most areas of Sonoma County the Flickers remain throughout the year, but "our" Flicker stays for the winter and leaves for his breeding ground in late March/early April. Because these birds are cavity nesters, they may need to relocate to find enough dead wood or less competition for nest excavation. Flickers can be found in almost any habitat with trees and nearby open ground for foraging. There are two subspecies of the Northern Flicker. The Red-shafted Flicker is distributed throughout California as well as most of the west. The Yellow-shafted Flicker is distributed in the east and the north. Where their ranges overlap, the Northern Flickers will interbreed (known as intergrades). During the winter, these intergrades and Yellow-shafted Flickers are seen in northern California. The Red-shafted Flicker is salmon-red under the wings and tail, and the male has a red moustachial stripe. It has a light brown body with barred back and wings, spotted underparts, a black bib, grey face, and a bold white rump which can be seen in flight. This is an exceptionally beautiful bird. The native peoples of the Sierra Nevada used the Flicker's bright wings and tail feathers in robes and ceremonial head-dresses. Flickers are a member of the woodpecker family. As a woodpecker, they possess unique physical attributes. Their short strong legs, sharp claws, and zygodactyl feet (two digits pointing forward and two digits pointing backward) are well adapted to perching, but are especially useful for clinging to vertical surfaces. A remarkably stiff tail helps brace them against tree trunks. Their chisel-like bill enables them to bore holes in search of food and excavate nesting cavities. A long-barbed tongue, which wraps around the back of the skull and attaches near the bones of the upper mandible, can extend a couple of inches to aid in extracting tasty grubs and worms from under bark and in recessed areas. The bone and muscle structure of their heads is adapted to absorb shock when they drum and peck against wood. Flickers do not sing, but have simple calls which are used to attract or keep in contact with a mate, announce territory, and express alarm. They also use nonvocal communication such as drumming on wood, which can sometimes include the side of a house. Flickers are especially vocal and noisy at the beginning of the breeding season. During this time, they have been compared to Mockingbirds whose call is so continuous that one wonders when they stop to eat or rest. The Flicker, unlike other woodpecker species, is commonly seen foraging on the ground where they feed mostly on ants. Last winter my husband Lance called from work to tell me he thought there was something wrong with a Flicker he saw outside his office. "It's hopping around on the lawn with a flock of Robins", he said. Although they do look odd foraging on the ground, I assured him it was normal. Besides ants, the Flicker eats beetles, termites, caterpillars, other insects, fruits and berries, and occasionally seeds and nuts. During the fall I often see our Flicker on a fence post in the middle of the field eating wild grapes, and when the persimmons are ripe, he will sneak bites of fruit when the resident Mockingbird isn't on guard. But when I no longer hear "keough keough", I know that spring has arrived and summer must pass before I hear our Flicker's call again. Duncans Mills, Cassini's Campground, Jenner & Willow
Creek Rd., Thursday, September 15 Shollenberger Park, Wednesday, September 21 Point Reyes, Thursday, September 29 Completes a One-Year Bird Survey From Gerald Moore, Chair of PWA On September 17th the Petaluma Wetlands Alliance completed a one-year survey of all the birds seen in or from Shollenberger Park. This survey was done on a weekly basis by five teams of expert birders who rotated on a weekly basis. We want to thank our team leaders Peter Colasanti, Lisa Hug, Andy LaCasse, Peter Leveque, and Richard Merriss for their outstanding effort. Actually it was a lot of fun, and the teams have agreed to continue the survey into the foreseeable future on a monthly basis. Throughout the year the teams counted about 115,000 birds (a few probably 52 times) representing 149 species. The data is being tabulated and will appear on our website www.petalumawetlandspark.org. Madrone Audubon Christmas Bird Count Our count center is in the Salmon Creek watershed and ranges from west of Sebastopol to the coast and from just north of the Russian River to the Estero Americana. Counters will be divided among 20 groups, and previous experience, though appreciated, is not necessary. This great day of birding with old and new friends is capped by a potluck dinner and oral reports from the team leaders who create a vivid picture of their team's version of "no leaf unturned". If you have counted before, you will receive an invitation by mail in mid-November. If your address has changed, or if you would like more information, please contact Joy Mander at 778-7865 or e-mail wscbc@aol.com.

Reviewed by Michelle Nijhuis There's something missing from the modern American childhood, says journalist Richard Louv. In Last Child in the Woods, Louv writes that unstructured outdoor play--the building of precarious tree houses, the lazy exploration of backyard forests--is fast becoming a thing of the past. Parental fear of strangers, schedules packed with activities, and the increasing availability of electronic toys, he claims, are keeping children indoors more than ever before. To Louv these "de-natured" children lack more than muddy shoes and scraped elbows; he cites studies showing that time in natural settings can reduce obesity, depression, and attention-deficit disorder. He also points to evidence that outdoor exploration fosters creativity, inspires new generations of naturalists and environmentalists, and even raises standardized test scores. To reunite children with nature, Louv offers practical advice to parents, suggesting modest joint expeditions into the natural world: "The dugout in the weeds ... the rivulet of a seasonal creek, even the ditch between a front yard and the road--all of these places are entire universes to a young child." Louv's case for outdoor play is a convincing one, and the possibility of a drug-free "nature" cure for many modern ills is too tantalizing to ignore. Boreal Birds. In April '05 the Boreal Songbird Initiative,
in partnership with Ducks Unlimited and the National Wildlife
Federation, launched a new and beautifully illustrated online
field guide to 260 species of boreal birds. The following month,
the Web site expanded to include 300 species of boreal birds.
This site features interactive maps, recordings, and detailed
information about the range and behavior of the birds that migrate
each fall from the 1.4 billion acres of Canada's boreal forest
to wintering grounds in the US and farther south. This new guide
at www.borealbirds.org/birds.html
is an identification aid and a reminder of the importance of
Canada's threatened and still largely unprotected boreal forest
to the continent's birdlife. One third of all North American
birds breed in the region, and almost half of North America's
ducks and geese use the boreal forest at some time in their life
cycle. Out and About International Migratory Bird Day (IMBD). May 2006. Members are needed on the planning committee for the 2nd annual celebration of the IMBD.
