Point Blue Conservation Science has become a leader in the conservation of migratory shorebirds and their habitats across the Pacific Flyway. During this talk, Blake will review the history of shorebird-focused programs at Point Blue, which date back to the founding of the organization in 1965 as Point Reyes Bird Observatory. He will highlight results from recent and ongoing efforts with a focus on the Central Valley, including the Pacific Flyway Shorebird Survey that has been supported by members of Fresno Audubon since its inception in 2010. Blake will wrap up the talk by looking forward at emerging programs for shorebird conservation, which highlight the increasing recognition by land managers and policy makers that these magnificent world travelers are sentinels of our rapidly changing environment.

In her presentation on drought and migratory birds in California’s Central Valley, Rachel will provide an overview of Central Valley wetlands and their importance for the Pacific Flyway, explain how drought is impacting the Valley’s bird habitats, and discuss actions we can take to ensure a more drought-resilient future.

Rachel Zwillinger bio

As the Water Policy Advisor for Defenders’ California Program, Rachel focuses on protecting the fish and wildlife that depend upon California’s waterways and wetlands. Among other priorities, she works to ensure that wetlands in the Central Valley receive sufficient water to support birds as they migrate along the Pacific Flyway, and strives to protect endangered salmon and other native species that depend upon the San Francisco Bay-Delta and upstream habitats.

Before joining Defenders of Wildlife, Rachel worked for three years as a litigation fellow for Altshuler Berzon LLP and the Natural Resources Defense Council. Prior to her fellowship, Rachel served as a law clerk to Judge John T. Noonan of the U.S. Court of Appeals for the Ninth Circuit, and Judge Marilyn Huff of the U.S. District Court for the Southern District of California. Rachel received a J.D. and M.S. from Stanford University, where she graduated Order of the Coif, and received her undergraduate degree in geosciences from Princeton University.

International Bird guide, naturalist and photographer, Benny Jacobs-Schwartz will share his dazzling bird photos, captivating videos, and animated story-telling to bring a slice of the tropics to California.
Delving into topics of migration, tropical speciation, and bio-diversity, this media rich journey will share some of the fascinating and unique birds that inhabit the new-world tropics.
Sure to both educate and entertain, this presentation will certainly leave you with a deeper understanding of tropical ecology, and knowledge about where some of our backyard birds spend their winters!

Benny Isaac Jacobs-Schwartz owns and operates a bird guiding business and lifestyle brand called BIRDS by BIJS (pronounced Bee-jus). Working seasonally as a naturalist guide, expedition trip leader, and international bird guide, Benny works in a variety of locations. Most recently bringing him to such exotic places like coastal Alaska, Trinidad and Tobago, and the Ecuadorian cloud forest.

Seasonally Benny or BIJS, is based in Los Angeles, where he leads public and private birding adventures to urban hotspots. He is also a passionate photographer, specializing in birds. He uses his impressive collection of content to leverage his prolific social media presence. Benny hopes his love of the natural world will inspire others to conserve the open spaces around them and look up more often from their phones!

Biologists have studied the charismatic wood duck for well over a century. What more could we possibly learn? As it turns out, quite a bit. New technology is revealing a rich and complex social underworld that is proving to be quite astonishing. We are employing automatic logging devices (passive integrated transponders, or PIT tags) that record every nest site a female visits, and population-wide genetic analyses of all breeding females and their offspring to follow the breeding behavior and entire life histories of wood ducks on several sites in California. We are focusing on a particularly curious nesting behavior whereby females lay eggs in the nests of other females in the same population (termed conspecific brood parasitism or CBP). Females in a wide variety of bird species lay their eggs in the nests of other conspecifics but despite its widespread occurrence the factors that promote parasitic nesting behavior remain poorly understood, in part because the sneaky parasitic females are rarely identified, but also because the information needed to assess the possible benefits of this behavior are often lacking. Are these females friends or foe? Does this behavior add or detract from the survival of females and their young, or the sustainability of the population? Our studies are providing some new insights and, in some cases, surprising us with the wide range of behavioral interactions among females in this enigmatic species of cavity-nesting duck.

Dr. John Eadie is a Professor and the Dennis G. Raveling Waterfowl Chair in the Department of Wildlife, Fish and Conservation Biology, University of California Davis. He joined the faculty at UC Davis in 1995 from Zoology University of British Columbia, where he completed by PhD degree. His research interests include the ecology, conservation and management of waterfowl and wetlands. His current work focuses on the management and conservation of wetland habitats, breeding waterfowl (mallards and wood ducks) in California, and linking ecological theory to wildlife management and conservation. He uses a combination of experimental and observational field studies, molecular genetic techniques in the lab, and population modeling approaches in his research.
