31 Mar April 2021 Yellowbill
Greetings, FAS members and friends. I hope that you are all staying healthy and safe out there.
On Tuesday, April 13, FAS will hold its monthly general meeting over Zoom. Our speaker for the evening will be Dan Airola, president of the Western Section of the Wildlife Society, who will be talking to us about Tricolored Blackbird ecology and conservation in the Sierra foothills. If you are interested in learning more about California’s near-endemic Tricolored Blackbird, you definitely do not want to miss this presentation! Please join us on Tuesday, April 13 at 7:00 PM. A link to register to get the Zoom information is here.
Thank you again to everyone who attended the March 9 general meeting. Beth Pratt’s presentation on the wildlife of Yosemite was very enthralling! For those of you who missed the meeting, you can view Beth’s presentation, along with other recent presentations, on our YouTube channel. Here is the link to Beth’s presentation.
FAS will be holding a virtual field trip on Saturday, April 10. The location will be Roeding Park and we will be focusing our attention on the heron rookery, which is very active this time of year. Please join us to check out the rookery and to see what else we might find! Here is a link for registration. Our hope is still to resume in-person field trips later in the year when it is safe to do so. Stay tuned for updates in the coming months!
If you are not already, please follow us on Facebook and Instagram, and subscribe to our YouTube channel. This is a great way to engage with us and stay in the loop!
To end this message, I’d like to share two photos. The first is a Western Meadowlark. Check out the pointed beak, the stripes on the crown, the black ‘necklace’ and the yellow on the breast (which aren’t the most visible in this photo since the bird was turned around), and the streaky brown backside. The second picture is an adult Pelagic Cormorant in breeding plumage. Notice the red in the face, the white whisker-like feathers on the neck, the purple and greenish sheen, and the slightly raised crests.
Please take care of yourselves!

April General Meeting
Status and Ecology of the Tricolored Blackbird
in the Sierra Nevada foothills
by Dan Airola
Tuesday, 13 April 2021, 7-8 pm
The talk will provide background on the unique population ecology of California’s near-endemic Tricolored Blackbird and the causes for its historic decline. Dan will review the importance of the the breeding population in the foothills based on surveys conducted over 2014-2020. Study results describing nesting and foraging habitats will be presented. Dan will also present the results of an analysis of the conservation status of the foothill population, which will describe habitat losses due to grassland conversion to orchards and vineyard and development and the levels of habitat protection currently afforded under existing conservation management, county zoning, and the several Habitat Conservation Plans.

Make a Pledge to Save Nesting Tricolored Blackbirds
The Tricolored Blackbird (TRBL) used to occur in the millions in the Central Valley, but the conversion of wetlands to agriculture has led to the rapid decline of the species. The TRBL is a colonial nester that may form large breeding colonies. Although colonies traditionally nested in tules and cattails, today in the Central Valley the colonies often nest in dairy silage. This has caused a problem for dairy farmers who need to harvest the silage when it has maximum nutritional value, a time when a colony may be present on their fields.
For the last five years, Audubon California has partnered with many local chapters, the federal government and the dairy industry to protect more than 680,000 nesting birds on farms, investing more than $2 million in federal funding to help farmers recover a portion of their losses incurred from delaying crop harvest. The silage buyout program was paid for by grants from the Natural Resources Conservation Service (NRCS), a federal agency.
We may need your help. The federal government has reduced the amount available for silage buyout, and that puts Tricolored Blackbirds at risk. Normally, the government helps farmers recover roughly 75% of their economic losses when they delay harvest to allow Tricolored Blackbirds to finish their nesting cycle. This year, the government will only be able to reimburse farmers for approximately 50% of their losses. Over the past several months, Audubon’s partnership has worked tirelessly to identify additional funding to cover this difference in payment so that we do not see an increase in hazing of nesting birds or harvest of nesting colonies. Just last week we were successful in securing funding from the California Department of Fish and Wildlife that can be used to support most farmers. We hope this will be enough.
We are asking you to join Audubon California and Fresno Audubon Society in pledging funding as a backstop to state funding to protect nesting Tricolored Blackbirds. These funds would only be used if the secured funding does not fully reach the 75% of costs to help farmers recover losses due to nesting TRBL. The funding gap Audubon is looking to cover is approximately $50,000.
There is currently a colony forming at Producer’s Dairy in Fresno County. We want to save that colony. If you make a pledge, Fresno Audubon Society will provide matching funds up to a total of $5,000 for all pledges, thus doubling your impact. This pledge will only be called in if the funding is needed, and the nesting and thus the need for funds will end in August. To make your pledge, click here.
General Meeting Speaker Schedule
Thanks to the efforts of President Rachel Clark and new board member and Program Chair 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, most 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 may offer virtual field trips on Saturdays for those wanting a narrated view of local birds.

How Do Birds Replace Their Feathers?
Lengthening days promise the return of warmth and with it, the return of migratory songbirds. In Canada, we welcome back our songbirds, relishing the profusion of song and color that once again fill wild (and not so wild) places. We revel in their company until summer ends and once again they leave for warmer lands.
But this image of migratory birds as Canadians just skipping off on holiday for the winter can be misleading. Some of these birds, including the Bullock’s oriole, can trace their rich evolutionary history back to an origin in the tropics — we’re just lucky to enjoy their company for a few short months as they indulge in the bounty provided by our temperate spring. But even that is too simplistic. Read more…
After more than 2 decades of searching, scientists finger cause of mass eagle deaths
More than 25 years ago, biologists in Arkansas began to report dozens of bald eagles paralyzed, convulsing, or dead. Their brains were pocked with lesions never seen before in eagles. The disease was soon found in other birds across the southeastern United States. Eventually, researchers linked the deaths to a new species of cyanobacteria growing on an invasive aquatic weed that is spreading across the country. The problem persists, with the disease detected regularly in a few birds, yet the culprit’s chemical weapon has remained unknown. Read more…
US report: Bald eagle populations soar in lower 48 states

Condors to return to Redwood National Park for first time in a century
California’s scenic north coast near the Oregon border is known for having the tallest trees in the world. But soon, it may be known for another superlative: the return after more than a century of the California condor.
Under a long-awaited plan published Wednesday by the federal government, biologists will start releasing America’s largest birds in Redwood National Park, dramatically expanding the range of a species that in the 1980s was so close to extinction that only 22 birds remained. Read more…
Giant extinct bird brains reveal “extreme evolutionary experiments”
Australian scientists have studied the biggest bird-brains in history for the first time. Paleontologists examined the brain cases of extinct flightless birds in the dromornithidae family – including some of the largest birds that ever existed – and found that they represented some weird evolutionary experiments.

Audubon at Sea
On the bustling docks of New Orleans, Louisiana, just before he boarded the merchant ship Delos and left to cross the Atlantic, John James Audubon purchased a baby alligator for a dollar. He likely thought the animal would be fun to draw, and the live specimen might impress the naturalists of Britain when he delivered his paper “Observations of the Natural History of the Alligator.” If his baby alligator, long hair, or French accent did not attract curious looks from the crew and fellow passengers, surely did his additional luggage of an enormous wooden portfolio, lined with tin to protect against shipboard rodents, which held over 300 drawings and paintings of birds. No one on deck at the time, including Audubon, could know that as a result of this voyage and that portfolio, he would go on to be a celebrity in his day and not only one of the most famous painters of wildlife in North American history, but the namesake, some two centuries later, of hundreds of birding societies and nature centers and a near synonym across the continent for environmental conservation.

From running in D.C.’s streets to soaring over them with his birds of prey
It seemed fitting that just before I called Rodney Stotts, the most unlikely of falconers, I’d looked out a window of my house and seen a group of crows harrying a bigger bird in the trees across the street.
“It was more than likely a red-tail,” Stotts said. “Crows are notorious for chasing off raptors, period.” Read more…

Sick finches – the ravages of a changing climate
The salmonella bacteria causes Salmonellosis, a common and often deadly bird disease. Late last year and early this year there have been numerous reports of sick and dying goldfinches and siskins in the coastal regions of Oregon, Washington, and northern California.
Infected birds have since been identified in the Reno and Truckee areas, and it was recommended to take down bird feeders for the entire month of February, as the illness is largely spread through contaminated feeders. And now, Salmonellosis has been identified in birds in Elko and Twin Falls, Idaho. Read more…
A peregrine falcon’s power to migrate may lie in its DNA
The peregrine falcon is best-known as the fastest animal on earth, but it’s got a second superlative: it’s the most wide-ranging bird of prey. Peregrines live on every continent except Antarctica, and make homes everywhere from Papua New Guinea to the desert Southwest to Chicago skyscrapers.
Some of those populations breed high in the Arctic tundra, and individual peregrines fly for thousands of miles and across multiple continents to nest on cliff banks along Arctic rivers. Read more…
