President’s Message

Greetings, FAS members and friends. I hope this message finds you healthy and safe.

Here we are in May, and spring migration is in full swing. Bullock’s Orioles are singing and chattering, Black-headed Grosbeaks are belting out their robin-like song, the distinctive, raspy song and calls of Ash-throated Flycatchers are filling the air in oak woodlands, and this is only scratching the surface. Personally, this time of year is my favorite!  I hope that you are all able to get out and soak up some late spring birding this month before things heat up here in the San Joaquin Valley.

We want to thank everyone who attended our April field trips, which were a great success.  We have some exciting field trips scheduled for the month of May, which are listed below.

  • Wednesday, May 11⏤Sycamore Island
  • Saturday, May 14⏤China Creek Park and Avocado Lake Park
  • Wednesday, May 25⏤Cricket Hollow

FAS resumed our beginning birder class and beginning birder hike in April out at the River Center. The plan is to hold another class and hike in May. If you are interested in attending the class or the hike, or both, please see the announcement later in the newsletter or look for event announcements via email and on FAS social media. If any of you have questions, please feel free to reach out to me at

  • Saturday, May 21⏤Introduction to birding class
  • Saturday, May 28⏤Beginning bird walk

I also want to mention that FAS has the following field trips schedule for the month of June:

  • Saturday, June 25⏤Tamarack Ridge

Anyone interested in these and other upcoming events can check out the FAS event calendar for more information and links to registration:

We would like to remind everyone of the current requirements for attending FAS in-person field trips and classes.  We are no longer requiring that participants be fully vaccinated. Masks are now optional for all FAS outdoor events. We still require that participants must not be exhibiting any symptoms of Covid-19. Registration is still REQUIRED for all in-person field trips, and participants must register individually. We appreciate your understanding and cooperation.

Thank you again to all of those who attended the April 12 general meeting. Pamela Flick of Defenders of Wildlife talked to us about the return of Gray Wolves to California, which was an outstanding presentation. If you missed Pamela Flick’s talk and would like to view the presentation, you can find it and other general meeting presentations on our YouTube channel at

The next FAS general meeting is scheduled for Tuesday, May 10. Dan Airola will be talking to us about the Yellow-billed Magpie, a species endemic to California and the FAS mascot. Here is the link to registration.

I’d like to remind all of you that FAS is on Facebook, Instagram, Twitter, and YouTube. Please give FAS a follow if you haven’t already! 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 I took recently of a Northern Rough-winged Swallow out at Jensen River Ranch. Note the small head and small beak, the long pointed wings, the rich brown backside, the dingy brown throat, sides and breast, and the white belly. Enjoy!

Please take care of yourselves!

May General Meeting

Yellow-Billed Magpie Population Status in Urban Sacramento
Dan Airola
Tuesday, 10 May 2022

Yellow-billed Magpie, Basalt Campground, by Jeremy Neipp

Program Description

Dan’s talk will cover his studies of the Yellow-billed Magpie population that occupies parks and other open space areas within the urban Sacramento area. Dan documents the previously unstudied ecology of Central Valley magpie populations. He describes new information that explains the occurrence and abundance of magpies in this area. He also solves the mystery of how magpies appear to have maintained stable and healthy populations in this urban area, while populations in more rural areas have been decimated by West Nile virus.

Speaker Bio

Dan Airola is a Wildlife Biologist and Ornithologist,  who has lived in the Central Valley since 1985. Dan conducts research and conservation efforts for birds of concern in northern California, often with a community science component. He began studies of Yellow-billed Magpies during 2020 after discovering that almost no ecological study of the species had occurred in the Central Valley. His other research and conservation program species include the Tricolored Blackbird, Purple Martin, Swainson’s Hawk, Osprey, and migratory and wintering songbirds. He is a Board member and Conservation Chair of the Central Valley Bird Club, and Editor of the journal Central Valley Birds. His recent book on 30 years of Purple Martin research and management is available at

Field Trip Schedule

Now that the Omicron surge of COVID-19 is past in our area, Fresno Audubon Field Trip leaders met Sunday 20 March to plan future field trips for more than a moth ahead. Please know that another surge could change these plans. Following is the current schedule for future trips. This schedule is subject to change due to cancelations.

May Field Trips

FIELD TRIP GUIDELINES DURING THE COVID-19 PANDEMIC ⏤ Fresno Audubon Society is again offering field trips during COVID-19 now that vaccinations are available to all. As we move into the endemic phase of the COVID-19 pandemic, everyone must determine their own level of risk aversion. The CDC’s newest recommendations state that masks should be optional when outdoors. It has been shown that a well-fitting N95 mask protects the wearer for several hours from an infectious dose of virus, so anyone concerned about exposure can choose to wear a mask near others if they feel at risk. Following are our current guidelines for our field trips.

  1. Participants must pre-register individually using the FAS event registration system.
  2. Participants must self-screen their own temperature before the outing and must not attend if they are feverish.
  3. Participants must consent to Fresno Audubon Society’s Liability Waiver by pre-registering.
  4. Social distancing is encouraged.
  5. Masks are not required, but participants are encouraged to wear a mask whenever they feel the need.
  6. Some field trips meet up at a central point before traveling to the field trip location. Participants may form their own car pools at these meetup points.
  7. Participants must contact their trip leader should they test positive for COVID-19 within three days following the outing so that we can notify others who attended the trip.

Wednesday 11 May 2022 ⏤ Sycamore Island with George Folsom

Join trip leader George Folsom to explore Sycamore Island. Sycamore Island is along the San Joaquin River in Madera County downstream from River West open space. It offers a variety of habitats: ponds, riparian, grasslands, oak woodlands and wetlands. We can expect ducks, raptors, herons, egrets, orioles, woodpeckers and perhaps migrating warblers and vireos among many others.

Register here.

Meet at the access gate off Ave 9, Madera County at 8:00 a.m.. See map below. This is a large property and we will do a combination of driving and walking. Walking distance will be 1 to 2 miles, but those who don’t care to walk can drive to most of the areas.

There are picnic shelters with tables for lunch and restrooms on the property. Participants should bring snacks, lunch (if desired), water, hat, sunscreen, and binoculars, and should dress in layers.

Checklist: ID, binoculars, bird guide, water, sun protection and lunch.

Registration is required for this event. If you have any questions, please reach out to trip leader at 559-435-9374 or

April field trip reports

Fresno/Clovis Wastewater Treatment Plant
Saturday 9 April 2022

Thirteen birders, including a few first-timers with FAS, braved steady 30 mph winds to bird the WTP last Saturday. The reward was 55 species, including a Peregrine Falcon that harassed the large flocks of Dowitchers and Least Sandpipers. Other highlights were three baby Barn Owls in a nest box, Swainson’s Hawks and a few Dunlin in breeding plumage. The Ruddy Ducks were transitioning to breeding plumage with some sporting blue bills and red feathers. The staff at the WTP were very accommodating. We want to especially thank Jennifer Loving for allowing us to enter the plant with our group and for providing a PortaPotty on the site!

Following is the eBird list for the day.

Sumner-Peck Ranch
Wednesday 13 April 2022

The April 13th Wednesday Audubon outing began on the River Parkways Sumner Peck Ranch  property. The morning was sunny, cool and breezy. As a group we tallied 46 species. We  walked a total of 2.6 miles and finished our outing at around 11:45am. While still in the parking  area located near the river the group observed a Lewis’s Woodpecker perched in an Oak. This was a first sighting for a number of the participants. A pair of Hooded Orioles were seen in the same area. As we made our way along the trail to the river we heard and observed White-crowned Sparrows and an Ash-throated Flycatcher amongst the Willows. Numerous Tree Swallows and Northern Rough-winged Swallows flew overhead. A 2nd year Bald Eagle glided above and  lingered long enough for us to observe the longer juvenile feathers among the shorter new ones along with the white belly and extensive white on the wings. A Red-tailed Hawk was also seen hovering above the young Eagle. From there we continued on to the Ball Ranch property where we followed the trail that moves through an extensive grove of Valley Oaks where we saw many Yellow-rumped Warblers and heard but didn’t see a Red-shouldered hawk. A Western Kingbird was spied across the river and on the water there were seen both Hooded and Common Mergansers.

One of the highlights of the walk was a group of 9+ Lewis’s Woodpeckers flying and vocalizing  animatedly for several minutes in a large Oak. Thank you to all who participated. It was a grand day outside.

Roeding Park
Saturday 23 April 2022

It was a beautiful morning as the nine birders gathered at Lake Washington in Roeding Park on Saturday.  There we observed the rookery that was teeming with bird life and activity.  Double-crested Cormorants, Great Egrets, Snowy Egrets, Cattle Egrets, and Black-crowned Night-Herons are all nesting there.  Birds were flying in and out, still nest-building or feeding chicks. There were hundreds of birds there.  On the lake were a large group of Wood Ducks, including one duckling. We spent quite a bit of time observing and photographing just at the rookery alone before moving on to the rest of the park where we observed a variety of birds including Acorn woodpeckers, Yellow-rumped Warblers, Goldfinches and House Finches among others.  At the ponds on the east side of the park we saw hundreds of Canada Geese with their chicks. Also in the ponds were another pair of Wood Ducks, and pairs of Mallards with their chicks.  We saw a total of 26 species, but the actual number of birds was pretty amazing. It was a lovely outing.

Lost Lake Park
Wednesday 27 April 2022

Twelve birders met at the Audubon Nature Trail at Lost Lake Park for some Spring migration action. Along the trail, numerous house wrens made their presence known with their loud, raucous songs. Bushtits were also plentiful, having ceased their flash-mob flocking behavior to settle into breeding mode. A group of yellow-rumped warblers was spotted, as well as a beautifully bright yellow warbler. A lone spotted towhee and several ash-throated flycatchers made their appearance. The find of the day, a Townsend’s solitaire, was also seen on the trail. The group next spotted western tanagers and Bullock’s orioles in the picnic area above the trailhead. Canada geese, ravens and starlings were numerous throughout the park. Buffleheads, wood ducks, mallards and common mergansers, a warbling vireo, and several other birds were seen along the river, for a total of 46 species.

Introduction to Birding Classes and Field Trips at the River Center

The River Parkway Trust and Fresno Audubon Society have teamed up to provide classes and bird walks specifically designed as an introduction to the popular pastime of bird watching. Join Fresno Audubon birding experts for fun classes and bird walks that introduce participants to birding and the amazing habitats found at the Coke Hallowell Center for River Studies. Each month there will be a 2-hour class introducing birding. The class will be followed later in the month with a 4-hour introductory bird walk around the grounds of the River Center. All are welcome to attend, including children. Fresno Audubon can loan binoculars to students who need them.

Introduction to Birding at the River Center
Saturday 21 May 2022
9:00 – 11:00 am

Class participants will learn how to use binoculars, why birding is a fun and valuable hobby, and about the resources available to help identify birds. After the initial class work, participants will accompany Fresno Audubon experts on a bird walk around the River Center property including the Hidden Homes Trail. This class will begin at the picnic tables just south of the Ranch House.
Participants should bring binoculars, snacks, water, and sun protection. Fresno Audubon will have binoculars to loan for anyone who doesn’t have their own pair.
There is no cost to attend. Children are welcome.

Introductory Bird Walk at the River Center
Saturday 28 May 2022

100 years later, condors are back

Carlos Avila Gonzalez / The Chronicle A juvenile California condor perches in a pen at Redwood National and State Parks in Humboldt County. The Yurok Tribe brought four birds from the Central Coast for reintroduction to Northern California.

The California condor, one of the rarest and most majestic birds on the planet, hasn’t flown over Northern California for more than a century. That will soon change. Members of the Yurok Tribe recently transported four condors, secured in dog crates in the back of SUVs, from the Central Coast to Redwood National and State Parks in Humboldt County, where they’re acclimating before being released into the wild later this month.

Earth’s Magnetic Field Is Like a Compass … But for Birds

Researchers claim to have sighted a bird not seen since 1944

If you ask the U.S. Fish and Wildlife Service, the ivory-billed woodpecker is extinct. It’s been more than half a century since anyone has seen the iconic animal, which was last officially spotted in 1944. Extensive searches through the swamplands and forests of the southern U.S. that it was once known to occupy have come up empty, which led to the declaration that the bird was gone forever. Not so fast. Despite being labeled as extinct, researchers from the National Aviary claim to have documented physical evidence that the bird is still alive in Louisiana. In a pre-print research paper that has not yet been peer-reviewed, lead author Steve Latta and a number of other researchers lay out the evidence that while the ivory-billed woodpecker may be reclusive, it has not been wiped out entirely. Read more…
