March General Meeting
The Wildlife Wonder of Yosemite
Tuesday, 9 March 2021, 7-8 pm
Conservation leader and author Beth Pratt has wandered in Yosemite for over 30 years, worked in the park for almost a decade, and makes her home outside its southwest entrance. “Yosemite is my north star,” she says, “And above tree line is my happy place—I will never tire of wandering in the park’s high country.” In this presentation, she’ll talk about the incredible diversity of wildlife in the park, and share some of her memorable encounters with the wild world, including pika, Yosemite toads, alpine butterflies, bears and much more.
Beth Pratt is a lifelong advocate for wildlife, and worked in environmental leadership roles for over twenty-five years, and in two of the country’s largest national parks: Yosemite and Yellowstone. As the California Regional Executive Director for the National Wildlife Federation, she says, “I have the best job in the world—advocating for the state’s remarkable wildlife.” Beth leads the #SaveLACougars campaign to build the largest wildlife crossing in the world in the Los Angeles area to help save a population of mountain lions from extinction, and her conservation work has been featured by The New Yorker, The Wall Street Journal, Washington Post, BBC World Service, CBS This Morning, the Los Angeles Times, Men’s Journal, and NPR.
Her new book, “I Heart Wildlife: A Guided Activity Journal for Connecting With the Wild World,” was released in August, and she is also the author of “When Mountain Lions are Neighbors: People and Wildlife Working It Out In California,” published by Heyday Books. Beth spends much of her time in LA, but makes her home outside of Yosemite, “my north star,” with her five dogs, one cat, and the mountain lions, bears, foxes, and other wildlife that frequent her backyard.

General Meeting Speaker Schedule
Thanks to the efforts of president Rachel Clark and new board member Lowell Young, we now have speakers scheduled for the remainder of the year. Since Lowell took the position of Program Chair he has reached out to many potential speakers, many of whom he met as president of Yosemite Area Audubon. This schedule is subject to change due to cancelations.
All in-person field trips are on hold. The board has decided to not restart gatherings as long as Fresno County continues to be a hotspot of COVID-19 infections, but the declining case numbers and increasing numbers of vaccinated people give us hope that we will be able to restart by September, the typical start of our field trip season. Until then we will again offer virtual field trips on Saturdays for those wanting a narrated view of local birds.
Saturday 20 March 2021, 9:00-10:00 am ⏤ Virtual Field Trip to River Center with Rachel Clark

Audubon Scientists Reveal Migration Bottlenecks Used by Tens of Millions of Birds
New study details how California’s Central Valley and the Colorado River Delta in Mexico provide food and shelter for globally significant numbers of migratory birds.
NEW YORK—(26 January 2021). Today, scientists from National Audubon Society published a study highlighting the high conservation value of California’s Central Valley and the Colorado River Delta for tens of millions of migratory landbirds each year. The study, led by Audubon’s new Migratory Bird Initiative and published in Ornithological Applications, estimates that more than 65 million birds use major portions of the Central Valley during fall migration, and about 17 million birds use the Colorado River Delta during spring migration. These regions are important migratory routes at the population level for dozens of species. Audubon scientists also found the Central Valley and Colorado River Delta to be migratory “bottlenecks,” because these regions had highly concentrated numbers of birds compared to similarly sized geographies at the same latitude. Protecting the Central Valley and the Colorado River Delta will be critical in conserving the populations of North American migratory birds into the future.
“Spring and fall migration seasons can be the most dangerous times of the year for migratory birds. We now know more than ever about bird migration, allowing us to take important steps to protect them,” said Bill DeLuca, PhD, migration ecologist with Audubon’s Migratory Bird Initiative and primary author of the study. “It’s hard to overstate the importance of protecting birds year-round, and not just in breeding and wintering habitat, if we want to secure their future.”
Using data from the Cornell Lab of Ornithology’s eBird Status and Trends team and population estimates from Partners in Flight, Audubon scientists summarized the abundance and spatial concentration of 112 species of migratory landbirds, week by week across the study regions.
Audubon researchers highlighted three major findings:
1) California’s Central Valley and the Colorado River Delta along the United States-Mexico border are migration hotspots for tens of millions of migratory birds as they fly up and down western North America.
2) The tens of millions of birds that fly through these regions represent major proportions of many species’ global populations. For example, in the spring, more than 27 percent of North America’s Tree Swallows migrate through the Colorado River Delta, and 80 percent of Lawrence’s Goldfinches migrate through the Tulare region of the Central Valley. In the fall, more than five percent of the Black-throated Gray Warblers migrate through the Colorado River Delta, and nearly 40 percent of Anna’s Hummingbirds migrate through the Central Valley. Full list of species and proportions available upon request.
3) The Valley and Delta act as migratory bottlenecks. As birds migrate through these latitudes, they funnel into these study regions. These high concentrations of birds makes them especially vulnerable to threats. Migratory bird conservation efforts and research should therefore focus on these key regions.
Audubon California, the state office of National Audubon Society, has worked on land and water conservation efforts in the Central Valleyfor decades.
“We’ve long known of the Valley’s importance to migrating waterfowl, but we were astounded at the sheer number of land-based birds who also depend on the region – for instance, nearly 40 percent of all Anna’s Hummingbirds migrate through the Valley in the fall. This study puts an exclamation point on what we already have come to see as the Valley’s hemisphere-wide importance,” said Meghan Hertel, director of land and water conservation for Audubon California.
The Central Valley and the Colorado River Delta are not just important for locally breeding birds, they are also important for common migratory birds that people enjoy in their backyards and parks up and down the Pacific Flyway.
“This study further demonstrates the outsized importance of the Colorado River Delta, particularly for the many birds that migrate through, including 27 percent of the global population of Tree Swallows in the spring and more than five percent of breeding Black-throated Gray Warblers in the fall, as well as many other land birds,”said Jennifer Pitt, Audubon’s Colorado River Program Director. “And while the Delta is just a remnant of what it once was—due to upstream water diversions, historic drought, and climate change—we know that targeted and strategic restoration projects with our partners in Mexico will result in positive outcomes for both people and birds.”
Many North American landbirds are declining at alarming rates, and we need to know the places that they depend on throughout the year. Audubon’s Migratory Bird Initiative is working with migration researchers and conservation practitioners to use the best available migration science to help steer conservation efforts to these critical landscapes.

Wildlife Photographer Captures ‘Never Before Seen’ Yellow Penguin
A wildlife photographer has shared a once-in-a-lifetime photo of what he believes is a “never before seen” yellow penguin. Belgian landscape and wildlife photographer Yves Adams was leading a two-month photo exhibition in the South Atlantic in December 2019 when the group made a stop on an island in South Georgia to photograph a colony of over 120,000 king penguins.

Desert mammals survive climate change underground. For birds, it’s a different story
In the struggle to survive the ever hotter deserts of California, there are winners and losers. Among the losers are desert birds, whose populations have collapsed amid the heat stress of climate change. The winners, it turns out, are small burrowing mammals, including the cactus mouse, kangaroo rat and white-tailed antelope squirrel, which take refuge from the sun underground. Read more…
Birds use massive magnetic maps to migrate – and some could cover the whole world
Every year, billions of songbirds migrate thousands of miles between Europe and Africa – and then repeat that same journey again, year after year, to nest in exactly the same place that they chose on their first great journey. The remarkable navigational precision displayed by these tiny birds – as they travel alone over stormy seas, across vast deserts, and through extremes in weather and temperature – has been one of the enduring mysteries of behavioural biology.

The World’s Largest Eagles
Eagles are birds of prey synonymous with strength, power, and tenacity. They are gracious birds used as national symbols in many countries such as the United States and Japan. In the avian kingdom, eagles can be found at the very top of the food chain. They are very successful birds in terms of hunting down prey and weathering the harshest environmental conditions. These heavily built birds have attracted interest from scientists and researchers who study their unique adaptations and habitats. Below are some of the biggest eagles in the world in terms of total length, wingspan and body mass. Read more…
