Chapter Meetings and Programs

Matthew Matthiessen on Birding Lydekker's Line

Tuesday, September 15, 2020 at 7PM - Zoom meeting

Join us this evening as we go Birding Lydekker’s Line with Matthew Matthiessen. Near the east end of the Indonesian archipelago, just before reaching New Guinea, lies Lydekker’s Line. Although invisible to the eye, it does mark the boundary forming the eastern limit of Asian bird species. East of the line can only be found Australasian birds while west of the line can be found an interesting mix of both Asian and Australasian avifauna. Geographically it separates New Guinea and the Raja Ampat Islands from the Malucca Islands. During the program we will visit several of the islands on either side of Lydekker’s Line. Some of these islands are very rarely explored but all contain endemic and rarely seen birds. These include such extraordinary gems as Buru Racket-tail, Lazuli Kingfisher, Kofiau Paradise-Kingfisher, and Wilson’s Bird-of-Paradise, arguably the most beautiful bird in the world. Matthew had the incredible experience of sailing among these islands in November/December 2018, seeing and photographing most of the endemic species in the region. He is an engaging and entertaining speaker, as well as a World-class photographer. This will be an evening you do not want to miss. See you there!

Dr. Gordon Walker on Fascinating Fungi: Falling into Winter

Tuesday, November 17, 2020 at 7PM - Zoom meeting

Dr. Gordon Walker has trekked for mushrooms across hemispheres, from California’s coastal forests to the north island of New Zealand, but his fungal fascination began in his home state of Massachusetts.

Around age five, Walker stumbled across what was then an oddity to him: a giant puffball (Calvatia gigantea) the size of his head. He showed the find to his mother, an accomplished artist and forager, who recognized the beach ball-sized fungi as edible.

Other experiences with fungi followed. When a stump in the yard was too expensive to remove, Walker’s father, a professor of biology at the Massachusetts Institute of Technology, plugged it up with chicken of the woods (Laetiporus sulphureus). Identifiable by its bright orange, ridged caps, this shelf mushroom rots wood, parasitizing its host.

Don't miss Dr Fun Guy as he shares his love of fungi with us.

Winter is here, COVID-19 and the holidays are upon us, and our local birds are helping themselves at our feeders again. Every year I am determined to identify those little critters, each and every one! Sure I make some progress, but what of those tough ones that look so similar, those little brown jobs hopping around under the feeder? Yes, I know most are sparrows and surely those feeding above are finches, but which species is each? I definitely need an expert!

Join us on Tuesday, December 15th at 7:00 p.m. for a Zoom Meeting “Get to Know Your Local Birds” where expert Bob Keiffer will point out distinguishing field marks of our Ukiah area birds. He will discuss and illustrate the sparrows and finches, jays and blackbirds, ducks and geese, as well as the raptors, the hawks and owls, all in digital living color from the comfort of your home! Ryan Keiffer will give an update about the changes to Ukiah’s Christmas Bird Count because of COVID-19.


Bring your tough questions for the experts. What birds can I expect in my back yard this winter? How do sparrows and finches differ? Is it really possible to see eagles in the Ukiah Valley? What are the ducks and gulls at Lake Mendocino?

Peregrine Audubon normally offers help in the field for identification through field trips and the Christmas Bird Count, but COVID-19 has made it challenging to share such information. Tune in to the December 15th Zoom to learn more about the Ukiah Christmas Bird Count, which takes place on Saturday, December 19th, 2020. We will explain how the 2020 Christmas Bird Count will work, introduce team leaders for the 7 areas, and how you can participate in more detail. This year we will emphasize the Yard/Feeder Watch aspect for those who live within the 15-mile diameter count circle. Want to find out if you live within the circle? Please CLICK HERE and zoom in to your property. Yard-birding has become much more popular this year and we are hoping this will be a way for many of you to safely participate in the Christmas Bird Count. A Tally Sheet showing expected species and those requiring further documentation will be available to those birding from home. We ask that you get your tally sheets to your area leader within 24 hours after the count! Certain area leaders might be willing to delegate birding regions to individuals if you reach out to the area leaders themselves, or contact Ryan Keiffer. Above all, you must follow all local Health Orders, maintain social distancing, and proper masking.

The really avid begin before daybreak and in all kinds of weather. The rest of us can participate for parts of the day or even count at home if we live within the 15-mile diameter count circle (which includes Ukiah). There will NOT be a beginners' count this year and sadly NO compilation potluck dinner, but by all means, contact Ryan Keiffer (707-671-5834) for more details!

There will be a Zoom Compilation meeting on Monday, December 21st at 7pm!

Jo Ann Baumgartner on Supporting Beneficial Birds and Managing Pest Birds

Tuesday, January 19, 2021 at 7PM - Zoom meeting

Jo Ann Baumgartner is the Executive Director of Wild Farm Alliance. She is the author of many publications on the intersection between biodiversity conservation and agriculture, including beneficial birds. Jo Ann will address the vital importance of promoting biodiversity, the significant role that birds play in controlling pests, and provide suggestions of ways that we can encourage beneficial birds and insects on our farms and in our gardens year-round. If pest birds are a problem, they can be discouraged with specific practices during the shorter periods when they cause damage.

Wild Farm Alliance works to promote a healthy, viable agriculture that protects and restores wild nature. WFA has spent the last 20 years addressing the current biodiversity crisis by helping farmers incorporate habitat to support wildlife and take advantage of the myriad of benefits nature can provide. More information about Wild Farm Alliance can be found at

*The ZOOM link for programs will be sent to the Peregrine Audubon email list. Check the Peregrine Audubon Society website to sign up for the email list if you are not already on it.

Lynn Schofield on Wildfires and Wildlife

Tuesday, February 16, 2021 at 7PM - Zoom meeting

Wildfires are an important part of many ecosystems around the world. Fires provide an opportunity for new growth, to return nutrients to the soil, and to create a wholly unique type of habitat. Many species are adapted for these ever-changing systems, and they have developed a wide variety of strategies for making the best of the post-fire habitat. However, these systems exist in a delicate balance. Recently, forest fires have been increasing in size, intensity, and frequency due to human activities, and even fire-adapted species are struggling to keep up. In this talk we discuss how animals survive and thrive in a system defined by fire and what we can do to help protect the balance of these special ecosystems.

Lynn Schofield is a biologist for the Institute for Bird Populations. Her research covers a diversity of topics including bird migration, forest fire ecology, and wetland conservation. In addition to using her research to help inform effective conservation strategies, Lynn also works to help make connections with nature accessible to all. She is one of the core members of the Cal Falcons social media project, a frequent trip leader for the Bay Area chapter of the Feminist Bird Club and a long-time volunteer for the Golden Gate Raptor Observatory.

You are cordially invited to come shorebirding on the North Mendocino Coast this spring and summer. Get the shorebird lowdown from Mendocino Coast Audubon's Becky Bowen at our March chapter program via zoom on March 16. Becky will tell the story of the chapter's Save Our Shorebirds conservation project and tell you where and when to find shorebirds in MacKerricher State Park.

Save Our Shorebirds grew out of a friendship between State Parks Environmental Scientist Angela Liebenberg and Becky in 2006. The two came up with the idea during long in-field surveys in MacKerricher State Park where Angela coordinated Western Snowy Plover volunteer monitors. The Western Snowy Plover is listed as threatened on the federal Endangered Species List. Local birding legend Dorothy Tobkin talked them into making the program about all shorebirds, because so many species that we see in MacKerricher State Park are listed as birds in decline by the National Audubon Society and American Bird Conservancy. Save Our Shorebirds (SOS) is an Audubon conservation program in cooperation with California State Parks.

Angela now is a Senior Environmental Scientist at California Fish and Wildlife. Becky, a retired production manager at ABC-TV in Hollywood, lives in Caspar and is the volunteer SOS data compiler and surveyor coordinator. "Coordinating the Audubon SOS program is not that different than working on an Academy Awards telecast," she says. "You plan it, budget it, put it on, follow the numbers, and pay the bills. Always have a backup generator, and take good care of the crew, and, oh yes, the stars."

The stars of SOS are the shorebirds of MacKerricher State Park and the volunteer surveyors who have gathered data about the birds since June of 2007. Please tune in to see photographs, listen to the SOS story, and hear what the birds have been telling us for 15 years.
