Domestic cats (Felis catus) can make wonderful pets, but their unrestrained presence on the landscape presents serious challenges. Outdoor cats are introduced predators that inflict serious harm to birds and other wildlife and contribute to a variety of public health risks. Cat management, however, has historically been complicated by unclear authorities, resource limitations, competing priorities, and a tradition of laissez-faire attitudes. This talk will review the wildlife conservation and public health evidence emphasizing the need for owned and unowned cat management and present solutions for cat owners and communities to effect meaningful change that will benefit cats, wildlife, and people.

Grant Sizemore earned B.S. degrees in Zoology and Environmental Science from Miami University in Ohio and an M.S. in Wildlife Ecology and Conservation from the University of Florida. He has experience in wildlife conservation research, education, and policy and is currently the Director of Invasive Species Programs at American Bird Conservancy, where he has run the Cats Indoors program for the last 10 years.

Scientists continue to make astounding discoveries about the navigational and physiological feats that enable migratory birds to cross immense oceans, fly above the highest mountains, go weeks without sleep or remain in unbroken flight for months at a stretch. Scott Weidensaul, author of A World on the Wing (2021), takes us around the globe -- to the shores of the Yellow Sea in China, and the remote mountains of northeastern India where tribal villages saved the greatest gathering of falcons on the planet, to learn how people are fighting to understand and save the world's great bird migrations. 

Scott Weidensaul's field research focuses on bird migration. He is a co-director of Project Owlnet, studying owl migration, and is a founder of the Critical Connections project, which is tracking the migration of birds that breed on National Park lands in Alaska. He co-founded the Northeast Motus Collaboration, which is creating a network of telemetry receivers to track the movements of bats, insects and small birds.

Mountain Lions in California are fragmented into subpopulations by roads and development. The Bay Area populations to the north and south of San Francisco are separated from each other and are separated from others further south and east by roads, development, and agriculture. Those to the north are affected by increasing road traffic, agricultural conversions for the wine industry, and other factors. Dr. Vickers will discuss the state of current knowledge, legal status, and ongoing research and mitigation efforts that are focused on these populations.

Dr. Winston Vickers is a wildlife research veterinarian with the University of California-Davis Wildlife Health Center (WHC). He has been studying mountain lions and other wildlife in California for 20 years and directs the WHC’s California mountain lion study. He collaborates widely with other mountain lion researchers, as well as collaborating on studies involving bobcats, wolves, Channel Island foxes, Santa Cruz Island scrub jays, and waterfowl. He has also worked on oil spill response with the Oiled Wildlife Care Network at UC Davis.

Islands have played a key role in both the development of new avian species and the extinction of others. Because they are isolated land masses, species which arrive on islands evolve separately from their parent group and through genetic drift eventually become unique. But because island species are restricted to small areas and have small populations, they are also susceptible to chance events, human-caused pressures, and predation by introduced species and introduced diseases.

In this presentation, we will focus on the wonders of these unique island species, as well as discuss some of the issues and threats to island avians.

Bob Lewis trained as a chemist and worked in the energy field for 33 years. He’s taught birding classes in the Bay Area for over 25 years and served as the chair of Golden Gate Audubon’s Adult Education Committee.  Recently he’s been giving classes and talks via Zoom.

For almost twenty-five years Marin Audubon Society (MAS) has been acquiring wetlands (or historical wetlands) and adjacent upland properties in Marin County; restoring, stewarding, and preserving the land as valuable wildlife habitat.  Some of these properties came very close to being developed but ended up with MAS due to the perseverance of those individuals who early on understood the value and importance of wetland habitat.  Some have been stewarded by an impressive group of dedicated volunteers and enjoyed for their beauty and bountiful birdlife by many people throughout the years.

Jude Stalker will take you on a virtual tour of several of these properties and fill you in on the interesting ways that they were acquired and of how they have been restored, enhanced, and stewarded to support the many native plants and animals that are populating them now.

Jude is a wetland biologist who has worked in and around the SF bay wetlands for over twenty years.  She is a long-time member of the board of MAS and spends much of her free time volunteering to help steward the MAS (and other) properties.

Speaker: Jen McBroom, California Invasive Plant Council
Register HERE for this Speaker Series Program

Topic:
San Francisco Bay is the largest estuary on the west coast of North America and a critical stopover along the Pacific Flyway migration route for millions of shorebirds and waterfowl.  Rimming the Bay between freeways, airports, and landfills remain precious tidal wetlands and opportunities to return salt evaporator ponds to functioning ecosystems.  Since 2005, the Coastal Conservancy’s Invasive Spartina Project has used airboats, genetic testing, sophisticated GIS, and a lot of hard, muddy work to push back the invasive plants that threaten habitat for shorebirds, waterfowl, and the endangered salt marsh harvest mouse. Learn about how hometown heroes are doing their part to address the global biodiversity crisis.

Speaker Bio:
Jen McBroom is a biologist at Olofson Environmental Inc. and has been counting Ridgway’s rails for the Invasive Spartina Project since 2005. She got her start in the tidal wetlands of the San Francisco Bay studying song sparrows and marsh wrens after finishing her degree at UC Davis. Since then, she has logged many hours in muddy boots mapping invasive plants and observing the wildlife at the edge of the Bay.
