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!

Speaker Bio:

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.

As spring approaches, our wintering sparrows prepare to leave and breeding species start to arrive, making it an ideal time to see a wide diversity of species.  Part of the challenge of identifying sparrows is recognizing their generic and species specific traits, including behavior and physical characteristics.  This presentation will give an overview of a handful of similar species that share common habitat but have differences of natural history, behavior, and field marks that help tell them apart.  Some of the similar species that will be discussed include Chipping and Brewer’s; White-crowned, White-throated, and Golden-crowned; Savannah and Vesper, and Sagebrush and Bell’s Sparrows.

Homer Hansen grew up in Willcox, Arizona surrounded by Sandhill Cranes in winter and Cassin’s Sparrows in summer.  Homer has a passion for sharing bird watching with others and is a regular field trip leader for several festivals and has served as chairman of the Wings Over Willcox Birding & Nature Festival for nearly 20 years.  Homer loves working with youths and co-founded the Sulphur Springs Valley Young Birders Club and the associated Arizona Young Birder’s Camp, non-profits dedicated to educating youths about birds (if not for COVID, 2021 would have been the 6th annual camp).  He also instructs workshops on sparrows, raptors, flycatchers, warblers, birding by ear, and bird ecology, including: the Lifelong Learning courses for the Tucson Audubon Society, the Southwestern Sparrows IFO for the American Birding Association, and educational workshops for the Western Field Ornithologists (WFO) conferences.  Homer is a life member of the WFO, Cooper Ornithological Society (COS), and Wilson Ornithological Society (WOS), and just completed two terms with the WFO board as chairman of the Student Programs Committee.
