PROGRAM, WORKSHOP, AND SPEAKER PROFILES

It’s clear that Covid-19 isn’t quite done with us. So in order to keep everyone safe, this year’s symposium will have three days of live in-person field trips around the Central Valley with two shorter days of virtual programs. There will be a mix of familiar itineraries and new specialty trips, with leaders new and old. Depending on your trip point of departure, you may choose to stay nearby or drive from home. In addition, you can decide whether to share a car with others.

We feel that this presents the safest option for all concerned, and many bird festivals around the country are also adopting this format. We wish we could meet as before, but the safety of our members and presenters continues be our priority. We are looking forward to seeing you in the field this year. This year’s CVBS is Friday, November 18, through Sunday, November 20, 2022.

All workshops and programs are virtual.

Opening Remarks: David Yee

4:00 PM — 4:15 PM

Welcome back! Though we wish we could see all of you in person, virtual is the next best thing. David will welcome back the symposium family and preview the next two days.

Bird Identification Panel: Moderated by Ed Harper

5:00 PM — 6:45 PM

This program has become an annual favorite. What better way to learn about the finer points of bird identification than by listening to the experts go through the process! Our illustrious panel will include Konshu Duman, Jon Dunn, Keith Hansen and Lynnette Williams. They will be presented with photos of difficult-to-identify bird groups (golden plovers, female goldeneyes, etc.), then each will mention what features they use to aid in clinching an ID.

Ed Harper, an esteemed birder, photographer, and presenter, was a long-time educator before taking up bird photography. He and his wife travel extensively, viewing and photographing the world’s wildlife and scenery. Ed spends much of his time in his beloved home state of Montana. He creates and directs the challenging Bird ID workshops at the Symposium and at Western Field Ornithologists conferences.

Revealing the Pacific Raptor Flyway – a Forty-Year Retrospective of the Golden Gate Raptor Observatory

Since the early 1980s, volunteers of the Golden Gate Raptor Observatory (GGRO) have been counting, banding, and tracking raptors of the Pacific Flyway. Forty years later, what have they learned? Join GGRO Director Allen Fish for the scientific headlines resulting from this annual autumn meet-up between several hundred community scientists and tens of thousands of birds of prey at the Marin Headlands – just above the Golden Gate.

As a cooperative program of the Golden Gate National Parks Conservancy and the National Park Service, GGRO staff and colleagues have uncovered many mysteries of raptor biology – from disease ecology to rodenticide impacts, from the timing of migration, to what fuels the migration of certain species. But even beyond the headline science, the GGRO has established systems for long-term raptor monitoring – for detecting population trends over time, for tracking movements and the finding the causes of injury and mortality in California’s birds of prey.

Please join us for a fascinating evening of raptor science and stories that will illustrate the immense value of community volunteerism in conservation biology.

Allen Fish, Director of the GGRO since 1985, was trained in avian biology at UC Davis, and returned there to teach Raptor Biology in the 2000s. He has presented the GGRO stories and science at conferences on three continents, and was given the Hawk Migration Association’s Maurice Broun Award for contributions to raptor conservation biology in 2003.

A World on the Wing: The Global Odyssey of Migratory Birds

Even as scientists make astounding discoveries about the navigational and physiological feats that enable migratory birds to cross immense oceans or fly above the highest mountains, go weeks without sleep or remain in unbroken flight for months at a stretch, humans have brought many migrants to the brink. Based on his bestselling new book, “A World on the Wing: The Global Odyssey of Migratory Birds,” author and researcher Scott Weidensaul takes you around the globe – with researchers in the lab probing the limits of what migrating birds can do, to the shores of the Yellow Sea in China, the remote mountains of northeastern India where tribal villages saved the greatest gathering of falcons on the planet, and the Mediterranean, where activists and police are battling bird poachers – to learn how people are fighting to understand and save the world’s great bird migrations.

Scott Weidensaul is the author of nearly 30 books on natural history, including the Pulitzer Prize finalist, “Living on the Wind: Across the Hemispheres with Migratory Birds,” and his latest, the New York Times bestseller “A World on the Wing: The Global Odyssey of Migratory Birds.” Weidensaul is a contributing editor for Audubon and writes for a variety of other publications, including Living Bird and Bird Watcher’s Digest. He is a Fellow of the American Ornithological Society and an active field researcher, studying saw-whet owl migration for more than two decades, as well as winter hummingbirds in the East, bird migration in Alaska, and the winter movements of snowy owls through Project SNOWstorm, which he co-founded. A native of Pennsylvania, he and his wife now live in New Hampshire.

How to Look at Shorebirds with a focus on Calidris and Tringa

As with so many things regarding to birding, learning more than just the identification tips is essential before mastering these groups. But backing up, one needs to learn how to start looking at shorebirds. Learn the common species thoroughly before seeking the rarities and learn status and distribution as well as behavior. Frankly, just slow down! We’ll cover fewer species in the hope that you will learn them. Quit worrying about how to identify the rarities when you are not fluent in telling the common species. We’ll focus on a selection of Calidris species as well as the regular Tringa species that have occurred in California.

In the concluding third of our time, we’ll review the results of the 63rd Supplement of the AOS Supplement to the AOS Checklist published in July 2022. As always, in addition to the results, we’ll discuss eternal themes for discussion, including issues involved with eponymous names. While in a sense I am a representative for the NACC (North American Checklist Committee), I have seldom been averse to offer my own personal opinions and questions and a discussion are encouraged.

Jon Dunn has authored or co-authored many papers on status and distribution and identification. He was chief consultant or co-author on all seven editions of all seven extant editions of the National Geographic’s Field Guide to the Birds of North America (from the 3rd to the 7th with Jonathan Alderfer) as well as Birding Essentials (2007) and co-authored with Kimball L. Garrett Warblers (1997) and Birds of Southern California, Status and Distribution (1981). Jon has been a member of the AOU’s (now AOS) Committee on Classification and Nomenclature (NACC) since 2000. Jon has led tours for Wings since 1977. Jon was a charter member for Western Field Ornithologists and has served for nearly two decades on their board, currently as President.

Lara Tseng is a 15-year-old college student at California State University Los Angeles majoring in biology. She has conducted research on Western Bluebirds and recently published a paper on Western Bluebirds and eggshell consumption in a peer-reviewed journal. Her favorite species is the Dunlin and she is particularly keen on studying the ten named subspecies, particularly the smallest subspecies, arctica, which breeds in northeast Greenland and winters in West Africa.
