Wintering waterfowl are arriving, which is a great excuse to talk about our annual drawing at the meeting on December 4th. Our grand prize this year features a lovely winter wetlands scene donated by Lorna Belen. The framed and signed Robert Bateman print is entitled “Across the Sky—Snow Geese” and is valued at $1,000. We […]

Yolo Notable Sightings: October 2019
We were treated to a late fall mega-rarity, a reasonably cooperative Worm-eating Warbler, a first county record and one of very few for the Central Valley. Despite howling winds, the bird was found Oct 27 in south Davis near Willowbank Ditch (ZP) and was enjoyed by dozens the following day. The other bird that brought […]

Breeding Bird Atlases
Projects to map the distribution of breeding bird species in a given area have covered numerous California counties. Called breeding bird atlases, they describe abundance, timing of breeding, and aspects of life histories. Trained citizen scientists do the field work. Their observations are synthesized into species accounts and maps, which reveal a great deal about […]
From the President: October 2019
Fall is here, and the bird season is changing too. We have a wide variety of field trips for you in the upcoming weeks. A new one is Alison Kent’s Introduction to Nature Journaling on October 12th. Try your hand at sketching—Alison is a great teacher. I’m on the board of directors of Audubon CA, […]

The Natural Resource Conservation Service in Yolo County
From a modest office near downtown Woodland, the USDA Natural Resource Conservation Service (NRCS) and its local partner, the Yolo County Resource Conservation District, help farmers and ranchers with a range of business matters. More importantly for Yolo Audubon, they also help rural landowners create and improve habitat for birds. For example, in the ranching […]

Yolo Notable Sightings: September 2019
September saved its biggest treasures for last, with a Buff-breasted Sandpiper found Sept 28 at the Woodland/Davis Clean Water Facility (SHo). Only the third county record, it didn’t stay more than a few hours before it was flushed by a Peregrine Falcon and never returned. The previous day, a Tennessee Warbler was discovered at Grasslands […]
From the President: September 2019
Welcome back to Yolo Audubon for the 2019-20 season. I hope everyone had a great summer and saw some good birds. The highlight of my summer was photographing a wonderful variety of species in British Columbia. Here’s a picture of me with Yolo Audubon friends JoAnne Fillatti and Lynda Goff and others getting a close […]

Yolo Notable Sightings: Mid-to-Late Summer 2019
The biggest mid-summer/early fall migrant surprises were a Glaucous-winged Gull in the Yolo Bypass Wildlife Area (YBWA) on July 4 (SH, BW)—and seen later at the Woodland Wastewater Treatment Plant (WWTP), a female Calliope Hummingbird in the town of Yolo on July 29 (BC, KSe) and a Black-and-white Warbler at the Sacramento Bypass on Aug […]

Nest Boxes in the City
A while ago I wrote about the marvelous success of the nest box installation program along Putah Creek masterminded by Yolo Audubon’s own Melanie Truan. Over the years, those nest boxes have produced nearly fourteen thousand fledgling Tree Swallows, Western Bluebirds, Ash-throated Flycatchers, House Wrens, and others. The effort has shown that demand for nest […]

Field Trip Report: Sierra Valley/Yuba Pass
June 8-9 2019 The Prelude to this trip was two one-day scouting trips. On Memorial Day all the roads were passable and temperatures mild, but the diversity of birds was really low. Six days later the birds had arrived and birdsong was everywhere. Our trip was six days after that. We had an odd start…at […]

Yolo Notable Sightings: May 2019
With the Yolo Bypass Wildlife Area closed due to flooding and water levels high everywhere, spring shorebird migration appeared to be a bust. That changed dramatically when the Davis Wastewater Treatment Plant (DWTP) decided to pump out one pond. Acres of mudflats appeared at the height of shorebird migration and the result was remarkable. Twenty-three […]
