Napa Solano Audubon 2020-21 Speaker Series

September 12, 2020 7:00 p.m. Dr. Matt Johnson presents:
Barn Owls in our Vineyards

Dr. Matt Johnson, professor in the Wildlife Department at Humboldt State University, will be speaking with us on Barn Owls. His expertise is wildlife habitat ecology, and he’s especially interested in studying how agricultural production and wildlife conservation can coexist. He and his graduate students have been studying barn owls in wine-grape vineyards since 2015. His talk will focus on what he and his students have learned about barn owls nesting in boxes in vineyards. Click this link to view his presentation: .

However, here is a link to a summary of Dr. Johnson's presentation on barn owls in our vineyards.

October 8, 2020 7:00 p.m. Dr. Bruce Lyon presents:
Sparrows in the Mist - the Complex Social Behavior of Golden Crowned Sparrows

Ornithologists often study breeding birds, and as a result, the winter ecology and behavior of migratory birds is relatively understudied. For the past 17 years, Dr. Bruce Lyon and his students have been studying a population of Golden-crowned Sparrows that winter in the University of California, Santa Cruz Arboretum. Individual sparrows return winter after winter to the arboretum and flock together with the same individuals as in previous years. Bruce's research has revealed remarkable social complexity in these birds that is similar in some ways to the societies of mammals, including primates. Learn about how the winter lives of these modest little brown birds—from the use of their black and gold crown patches as signals, to the winter songs of males and females—are surprisingly more complex than previously thought.

November 12, 2020 7:00 p.m. Matt Allshouse presents: Conservation Ranching

Matt Allshouse from Audubon California will speak on Conservation Ranching; an effort to restore America’s grasslands to benefit birds, people and the planet. Healthy grasslands once stretched across broad expanses of California and the U.S., supporting a range of wildlife and defining a way of life for generations of Americans. But about 80 percent of our native grasslands have fallen to development and other threats —and the birds that depend on them are disappearing, too. The future of grassland- dependent birds like Grasshopper Sparrow and Mountain Plover are now in question. Audubon knows that the commercial use of grasslands is critical for local economies and national prosperity. But business success doesn’t have to come at the expense of nature. So we’re connecting bird-friendly ranches with eco-conscious consumers, giving ranchers new ways to stay competitive in the marketplace. At the same time, ACR’s science-based ranch management methods improve soil health and water quality, mitigate flooding and erosion, and capture ozone-damaging carbon. Come learn more about Conservation Ranching with Matt Allshouse and join Napa Solano Audubon members on Thursday, November 12 at 7:00 p.m. Click this link to view his presentation:

January 14, 2021 7:00 p.m. Alvaro Jaramillo presents: Birding the Mediterranean Regions of the World

Join us and Alvaro Jaramillo for a fun talk about how climate affects the environment, as well as the birding! The climate type is the Mediterranean zone with dry summers and wet winters – sound familiar? We live in a Mediterranean-type climate, and this happens to be the type of region where people produce the finest wines. But similar climates don’t always have similar birds, although some of the parallels are striking. In some cases, there are clear-cut differences, while in other situations we have very different birds that fit a similar niche in separate Mediterranean parts of the world. Mediterranean climates are unique enough that they have created a set of special habitats associated with the regions where they are found, like our chaparral, and in these areas there are also a variety of endemic birds. We will take a quick visit to birding areas in Spain, Chile, California, and South Africa! Come see a view of what makes Mediterranean regions tick, why they are also seabird hotspots, the great birding to be enjoyed, and maybe we will even talk a bit about the wine!

February 6, 2001 Mark and Lucas Stephenson Present: Birding the Bay Area Wetlands with an Avid Young Birder

We have a wide variety of wetland birds that inhabit the marshes, soughs, and bays of the Bay Area. Over the past 6 years we have observed the great diversity of birds in Bay Area Wetlands from Huichica Creek and American Canyon Wetlands in the North to Hayward Regional and Don Edwards National Wildlife Area in the South and from Point Reyes National Seashore and Bodega Bay in the West to Colusa, Yolo Bypass, and Consumnes River Preserve in the East. This presentation by Mark Stephenson, our Napa-Solano Audubon President, about Bay Area Wetland Birds with his son Lucas was created for the SF Bay Flyway Festival. Feel free to enjoy at your leisure! Click this link to view this presentation: .

February 11, 2021 7:00 p.m. Dr. Wendy Schackwitz presents: Do Blackbirds Sing in the Dead of Night?

Join us and Dr. Wendy Schackwitz will share her research on what she has learned from recording Tricolored Blackbird Colonies over the last 4 years. Analysis of Tricolored Blackbird vocalizations reveal intimate details about life in a colony. The Tricolored Blackbird is a California specialty that is currently experiencing a dramatic population decline and has been listed as Threatened under California’s Endangered Species Act. Determining why some colonies are successful, while others fail will be key to recovering this species from the brink of extinction. For the past four years former NSAS President, Dr. Wendy Schackwitz has used audio recordings of Tricolored Blackbird colonies to gain insight into their reproductive timing as well as why some colonies are successful, and others fail. In her talk she will discuss how her analysis of thousands of hours of audio recordings revealed a fascinating and detailed picture of the intimate lives of a Tricolored Blackbird colony. Click this link to view this presentation on YouTube:
