Chapter Meetings and Programs

Robert B. Douglas on What's Going on with Barred and Spotted Owls?

Tuesday, September 19, 2023 at 7PM - Ukiah City Council Chambers

Tonight Robert B. Douglas will present a program about the participation of Jackson Demonstration State Forest (JDSF) in a barred owl removal study that was designed to address regional northern spotted owl population decline. Robert will speak about spotted owl population trends, societal views, conservation implications, and the future of barred owl management. He will be joined by Kyle Farmer, Community Education Specialist, U.C. Cooperative Extension, Mendocino County. He has a background in international development, sustainable agriculture, and prescribed fire, and is currently undecided on the barred owl question. Kyle will be sharing a brief history of the Barred Owl Stakeholders Group – a series of stakeholder meetings led by Clark University ethicist Bill Lynn to explore this challenging topic.

Robert is Senior Environmental Scientist (Specialist) working as the State Forest Biologist for Jackson Demonstration State Forest since 2021. He has a B.S. degree in Environmental Biology from Humboldt State University (1997) and a M.A. degree in Ecology and Systematics from San Francisco State University (2003). Prior to state service, Robert worked as a biologist to improve conservation and management of non-timber forest resources on industrial timberlands in Mendocino County. He has a broad interest in natural history, conservation biology, and forest ecology which has led him to work on diverse array of projects to better understand how disturbance and other environmental factors influence plant, fungal, and animal communities over time. Some of the projects he has been involved with during his career include research on belowground fungal communities in different forest stands, spotted owl nest-site characteristics, songbird habitat associations, salmonid population dynamics, carnivore distribution, tailed frog and giant salamander population genetics, and the post-fire response of redwood.

The focus of Robert’s position at JDSF is to provide technical expertise in the conservation and management of non-timber forest resources (fungi, plants, fish, herpetofauna, birds, mammals, and other wildlife) associated with disturbance activities that occur on the forest (e.g. timber harvesting, fire and fuels management, recreation, restoration, and research). His primary responsibility is to ensure that JDSF projects comply with the law (e.g. Forest Practice Rules, CEQA, and federal and state endangered species acts) and the forest management plan. He is also developing a plan to monitor the diversity and distribution of species across the forest to better understand how their populations change over time with habitat and other environmental changes. This involves collaborating with outside researchers, agency biologists, user groups, and conservation organizations to conduct experiments (e.g. invasive species control, fuel treatments, etc.) and/or restore habitat, the results of which will inform and guide future management across the forest in an adaptive management framework.

This evening Carrington Hilson will present on elk research and management in coastal northern California, including Del Norte, Humboldt, and Mendocino counties.

Carrington is the Elk Research Biologist for the California Department of Fish and Wildlife in the Northern Region. She has a B.S. degree in Biology from Virginia Polytechnic and State University (2004) and a M.S. degree in Wildlife from California State Polytechnic University, Humboldt (2013). Prior to starting her work with elk in 2016, Carrington was the Wildlife Disease Biologist for the Arizona Game and Fish Department, managing the statewide chronic wasting disease surveillance program and performing captures statewide. Some of the projects she has been involved with during her career include pronghorn and bighorn sheep relocations, disease in wildlife and livestock, ecology of sylvatic plaque, West Nile virus detection, and demography of small mammal, passerine, and raptors.

The focus of Carrington’s position is to obtain a comprehensive assessment of elk populations and their ecology in northern California. Obtaining an accurate estimate of Roosevelt elk (Cervus canadensis roosevelti) and tule elk (C. c. nannodes) populations in northwestern California is difficult because the species is wide-ranging, and most herds occupy locations that hinder traditional survey methods. This study is working to estimate abundance and compare several survey techniques and their usefulness to monitor elk populations. This study is also examining habitat use, resource selection, behavior, recruitment, disease, and cause-specific mortality. This information will allow the Department to develop a long-term elk monitoring program that allows for management and conservation of elk.

Join us this evening for a fascinating presentation by local falconer Art Haschak. Art grew up in Willits and has been flying falcons and hawks since he was 17 which means he's in his 51st year as a falconer. When Art last spoke to PAS about 10 years, he brought his female Peregrine “Sis-Sis” and discussed general raptor identification. This time he'll focusing on the various races of Peregrine with a little insight on the differences between Peregrines and Gyrfalcons, Prairie Falcons and Merlins. Art currently has a seven year old daughter of Sis-Sis, a six month old daughter, and a one and a half year old Red-Naped Peregrine, which is native to the Middle East and Africa. He hopes to bring at least one of these birds as we discuss the interesting differences in hunting styles between the different falcon species.

This evening will be our annual Know Your Local Birds Slideshow and Christmas Bird Count Review with George Gibbs and Bob Keiffer. Bob will be presenting his excellent slideshow introduction to our local wintering birds. George will update us on signup details.

Winter is here, the holidays are with us, and our local birds are helping themselves at our feeders again. Every year I am determined to identify those little critters, each and every one! Sure I make some progress, but what of those tough ones that look so similar, those little brown jobs hopping around under the feeder? Yes, I know most are sparrows and surely those feeding above are finches, but which species is each? I definitely need an expert!

Peregrine Audubon's Christmas Bird Count (CBC) has those experts who can help bring us a step closer to our goal. Join us on Monday, December 11 at 7:00 p.m. in the Ukiah City Council Chambers when Bob Keiffer will point out distinguishing field marks of our Ukiah area birds. He will discuss and illustrate the sparrows and finches, jays and blackbirds, ducks and waders, as well as the raptors, the hawks and owls, all in living color.

Bring your tough questions for the experts. What birds can I expect in my back yard this winter? How do sparrows and finches differ? Is it really possible to see eagles in the Ukiah Valley? What are the ducks and gulls at Lake Mendocino? Anyone interested in bird calls? Our speaker can help with that too.

Peregrine Audubon also offers help in the field. Beginners and experienced birders can come to the December 11 meeting at 7PM and sign up for the Count, which takes place on Saturday, December 16. We will explain how the Christmas Bird Count works, introduce team leaders, and match you with a group that can best help take you that next step toward better bird biology.

The really avid begin before daybreak and in all kinds of weather. The rest of us can participate for parts of the day or even count at home if we live within the 15-mile diameter count circle (which includes Ukiah). There will be a beginners' count starting at 10AM and meeting at the gate to Mendocino College on Hensley Creek Road..

We meet after the CBC for a potluck dinner in the Grace Hudson Museum Public Room on South Main Street. Bring a dish, something to drink, and your eating utensils and join us at 6:00 p.m.

Join us on Zoom for a fascinating evening with Karla Bloem, the founder and Executive Director of the International Owl Center. Karla acquired Alice the Great Horned Owl to use in educational programs in 1998 and began studying Great Horned Owl vocalizations in 2004. Since then, a real-life soap opera has played itself out with over 25 captive and wild Great Horned Owls that have formed the basis of an in-depth vocal study on the species. You'll experience owl dating, divorce, territorial defense, and more as you learn about their vocalizations and their meaning. And one of Karla's owls will join her in a live appearance.

Karla is now the world authority on their vocalizations and has given presentations in The Netherlands, Germany, Argentina, Italy, Portugal and South Africa. Alice’s popularity led Karla to create the International Festival of Owls, the first full-weekend, all-owl event in North America that has served as the inspiration for similar festivals in Italy, Nepal and India. Karla and Alice testified before the Minnesota House and Senate environment committees to successfully gain protection for Great Horned Owls in 2005. Karla received the Brother Theodore Voelker Award from the Minnesota Ornithologists’ Union in 2001, was awarded a Bush Leadership Fellowship in 2008 and a World Owl Hall of Fame Special Achievement Award in 2021. She has assisted several authors (including Jennifer Ackerman) and filmmakers and has appeared on Animal Planet and the CBC’s “The Secret Life of Owls.”

The international Owl Center the only all-owl education center in the United States. It opened in an historic storefront in the little town of Houston, MN (population 979) in 2015, with owls commuting to work in the Owlmobile each day from their aviaries in the country. Property for a new 22,000 square foot facility in a park at the edge of town has been acquired, architectural concepts are now completed, and the silent fundraising phase is starting this winter. You can see the plans at

Special thanks to Redbud Audubon for their contribution to the program description.

Join us for an evening all about monarch butterflies, monarch caterpillars, and the amazing interactions happening everyday in our suburban and urban garden ecosystems! The focus of this talk will be on the threats facing monarch caterpillars and how to use ecological concepts to guide management decisions in our own gardens. Growing milkweed has increased dramatically in recent years, but gardeners can be overwhelmed with recommendations on what to grow and how to grow it. We will learn about some of the general recommendations, the science behind them, and how understanding our own gardens can help us tailor recommendations to our own garden ecosystems. We will also learn about the dissertation research of our speaker, Leslie McGinnis. The focus of Leslie’s dissertation is on the milkweed gardens of the East Bay of the San Francisco Bay Area. Specifically, she is interested in (1) the social, commercial, and ecological processes shaping and connecting these gardens, (2) the plant species composition of these gardens and winter availability and care of milkweed, (3) community ecology surrounding predation of urban monarch caterpillars, (4) how host plant species traits, garden landscape characteristics, and season impact predation pressure on caterpillars.

Leslie McGinnis is a doctoral candidate at the University of California Berkeley. Leslie grew up gardening in a rural area outside of Spokane, Washington in the foothills of the Selkirk Mountains. As a little girl, she would go with her family to old homesteads and fields and rescue heirloom perennials and native plants before they were bulldozed. Leslie earned her BS at the University of Washington studying topics ranging from the impacts of ecotourism on southern resident orcas, to the impacts of non-native tamarisk on insect communities, to tropical forests, to the evolutionary ecology of chili peppers. After graduating, she taught middle school science in Los Angeles with Teach For America. During this time, she earned her teaching credential and partnered with the Sierra Club Inner City Outings program to take her students on hiking and camping trips in the Santa Monica Mountains and to tidepool and salt marsh ecosystems. Leslie earned her M.S. in Ecology and Evolutionary Biology at the University of Michigan Ann Arbor with a strong emphasis on agroecology and continued her graduate studies in Berkeley. In addition to her doctoral research, Leslie has continued her commitment to education and increasing diversity in STEM fields. She has taught courses on urban gardening and agroecology, climate change in California, insect natural history, and interactions between society, culture, and the environment. Additionally, she guided Environmental Science senior thesis students through the development and completion of individual research projects and mentored incoming first generation college students through Berkeley’s Bridge Connect program. Firmly believing that science is for everyone, Leslie values research and research methods that are accessible to the general public and that honor the wealth of knowledge of gardeners, farmers, and backyard naturalists.

Did you know The Bird Rescue Center, located in Sonoma County, sees roughly 100 patients from Mendocino County? Our work has never been more important in this climate change-driven era. Come learn about The Bird Rescue Center and hear behind-the-scenes stories of Bird Rescue and unique avian observations from Ashton Kluttz, Executive Director of the Bird Rescue Center in Santa Rosa.

The current Executive Director of The Bird Rescue Center, Ashton Kluttz completed her BA in Environmental Studies at Washington College (MD). She began her tenure with Bird Rescue in 2010 and her career as a wildlife rehabilitator in 2009 with The Marine Mammal Center where she served in the Stranding Department. Striving to provide the best care for our local wildlife, she obtained her Registered Veterinary Technician certification in 2018, has co-authored a chapter on towhee care currently included in a wildlife care book for facilities around the world, and served on the board for the California Council for Wildlife Rehabilitators that provides community, protocols, and information to all California wildlife facilities.

Under her direction, Bird Rescue has forged stronger relationships with other wildlife and education facilities and within the community. She has come to appreciate individual species’ behaviors and could discuss their quirks at length. In her spare time, she catches up with her family on the East Coast and enjoys taking photos of food on her dogs' noses.

Peter Van De Burgt on Salmon Habitat Restoration on the Ten Mile and Garcia Rivers

Tuesday, April 16, 2024 at 7PM - Ukiah City Council Chambers

Ten Mile River Estuary Coho Salmon

Join us this evening as Peter Van De Burgt updates us on salmon habitat restoration on some of our local rivers. On the North Coast, The Nature Conservancy is working to protect and restore a network of coastal floodplains and estuaries that includes the coastal reaches of the Ten Mile River, the Navarro River and the Garcia River. This network will conserve biodiversity, increase coastal resilience, and provide some of the southernmost habitat for wild coho salmon along the Pacific Coast.

Our work is about improving conditions in these rivers and their estuaries by reconnecting floodplains, building wood jams (large structures within the streams themselves), and restoring the natural form and function of whole riverscape systems. This work provides critical habitat for fish and it's helping to demonstrate the effectiveness of estuary and floodplain habitat restoration, creating a blueprint that can be replicated across the region. To date, TNC has constructed three large restoration projects in the Ten Mile River and one in the Garcia River estuary, with three more projects slated for construction in the coming years."

A quick recent success story: This winter, in the Ten Mile River, we have observed more adult salmon returning to the river to spawn than we have ever seen in our 10+ years of monitoring. It is looking like this will be the best spawning year for coho salmon that we have seen in a long, long time! A glimmer of hope for a species otherwise teetering on the brink of extinction in California.

Dave Bengston on How to Turn Your Yard into a Bird B&B

Tuesday, May 21, 2024 at 7PM - Ukiah City Council Chambers

Dave Bengston Bullock's Oriole Rose-breasted Grosbeak Say's Phoebe

Dave Bengston, one of Peregrine’s own board members and our Education Chair for the last 16 years will be telling us how to attract birds into your yard and be environmentally helpful at the same time. Topics will include native plants, cats, window collisions, pest control, providing feed and water and nest boxes.

Dave grew up in Modesto, California where he collected feathers at an early age. In college he gained a passion for plants and mushrooms. He graduated from the University of California at Berkeley in 1971 with a degree in Social Sciences. In 1972, he accepted a job with the Mendocino County Department of Agriculture and he moved to Ukiah with the ulterior motive of studying mushrooms. He continued to have an interest in plants, both on the job and in his personal life. He was a Nursery and Seed Inspector and he was a charter member of the Sanhedrin Chapter of the Native Plant Society. In 1990 he began to build birdhouses, a hobby he continues to this day. He has been doing the Winter Feeder Watch for 22 years with Cornell University and doing eBird for 15 years. For fifteen years, he has been volunteering his time to help teach Flight School at Redwood Valley Outdoor Educational Project, and in more recent years on bird hikes at the University Research Extension Center for the University of California.

Dave served as Agricultural Commissioner and Sealer of Weights and Measures for Mendocino County from 1989 until his retirement in 2009. During his tenure, he enforced the laws pertaining to pesticides, exotic pests and quarantines, farmers markets and the organic food laws, with pesticides being his primary focus. For his entire career he was very active in biological control and he was always on the statewide committee for biological control. He was chairman of the Biological Control Committee three times and expanded and combined the committee to include Integrated Pest Management; he presided over the state Biological Control Conference in San Diego, a collaboration of governments, industry and the University of California. He organized a statewide survey to prioritize weeds in every county, which convinced U.S.D.A to make Yellow-star Thistle its top priority in California for biological control. He was responsible for bringing several biological control agents into the county for the control of invasive weeds. He was the head of the International Broom Initiative, which was an effort to procure bio-control agents for the Brooms and Gorse. When the county passed the ordinance to ban Genetically Modified Organisms, Bengston became the first person in the country to enforce such an ordinance.

Field Trips

Field Trip Guidelines: Everyone is welcome! These guidelines apply to all Peregrine Field Trips. Please take a moment to read them if you are new, or use them to refresh your memory if you have birded with us before. The times listed are the departure times - not the assembly times. Please arrive early! Many of the trips are out of the area and require an hour or more of driving, so promptness is necessary.

Due to insurance requirements, Peregrine Audubon leaders are not allowed to organize carpools. Participants are, however, encouraged to voluntarily share rides. Any carpool arrangements are private arrangements between the driver and the passengers. Drivers must carry adequate insurance coverage. Please be courteous and share gas expenses with the driver

Most trips are all day affairs, but at times various people need to get back sooner. By arriving 15-20 minutes early such necessary travel arrangements can be made. You will probably want to take a pack with lunch, water, hat and appropriate clothing - coats, rain gear, etc. - , binoculars*, camera, and perhaps notepad and field guides.

*Binoculars are important, but loaner pairs may be available for newcomers. If you have some to loan, please bring them along.

Clear Lake State Park

Saturday, September 23, 2023

Join us for a morning of birding at Clear Lake State Park. This beautiful park has a variety of habitats that support a great diversity of birds, and it is a great time of year to be out in the oaks enjoying the fall colors. Expect to see some birds we seldom see in Ukiah- American White Pelicans, Bonaparte’s Gulls, and an abundance of water birds. We depart from the CVS parking lot at 8 am, and should arrive at the Visitor Center by 9 if you prefer to meet us there. Parking fee is $8 per vehicle. Be sure to bring a lunch and something to drink for a picnic in the park. For those wishing to continue birding in the afternoon, we will probably be visiting the Lakeside County Park and Rodman Slough areas on our way back to Ukiah.

Willits Mitigation Lands and Waste Water Treatment Plant

Saturday October 21, 2023

Peregrine Audubon in conjunction with MCRCD, Mendocino County Resource Conservation District, will be doing a bird focused field trip on the Willits Bypass Mitigation Lands along Outlet Creek. We hope to see early raptors migrating into the valley, White Tailed Kites and Early Northern Harriers, and see the tail end of the neotropical migration south along the riparian corridors. The Dogwood, poison oak, blackberry, and rose hips will be ripe and attracting may juvenile birds on their migration from north to south for the Fall and Winter. The tule Elk should have begun bugling so we should hear some of them too.

This trip will have limited space available so you must RSVP at: We will meet at 8:30 at the Mendocino County Museum.

Covelo and Round Valley

Saturday, November 18, 2023

Join us for a fall visit to the Round Valley area, one of our favorite destinations. This beautiful valley with its open grasslands and large Valley Oaks is home to a number of winter visitors not commonly seen in the Ukiah area. In past years birds of note here have included Bald Eagles, Ferruginous and Rough-legged Hawks, Peregrine and Prairie Falcons, Lewis’s Woodpeckers, and Canyon Wrens. Time and weather permitting we will continue east to the Black Butte/Eel River campground for a picnic and more birding. Meet before our 8:00 am departure from the CVS parking lot, or at 8:30 at the parking lot in front of Willits High School. We should reach Covelo and Keith’s Market around 11:00.

Beginner’s Bird Walk at the Ukiah Wastewater Treatment Plant.

Saturday, February 24, 2024

At the Ukiah Wastewater Treatment Plant, or UWTP, you can probably see more species of birds in less time than anywhere else in the Ukiah valley. Its habitat range is outstanding: riparian areas adjacent to the Russian River, settling ponds, beautiful stands of mature valley oaks, blackberry thickets, and adjacent open grasslands. Meet at the UWTP office area at 8:30. The walk around the oxidation ponds is about one mile, all on level ground.

Lake Mendocino North Shore

Saturday, March 23, 2024

We will be birding the north end of Lake Mendocino this morning. We will be focusing on the stretch between the boat launch adjacent to the inlet, and along the Pomo A day-use area. There are great views of the lake from this location, so we will be searching through the water birds for wintering ducks and grebes. Loons are a possibility here as well. Other target birds will include wintering song birds and raptors along the lake shore. Bald Eagle is a good possibility. We will be leaving the CVS parking lot at 8:00 and expect to arrive at the parking area above the north boat launch at 8:30.
