Hello fellow birders, I went out and compiled my inaugural California Bird Atlas <https://www.californiabirdatlas.org/> survey checklists today, focusing on my home block of Oakland East CW. I covered the Morcom Rose Garden fairly thoroughly and then took a quicker swing through Piedmont Park. Of possible broader interest, I encountered a White-throated Sparrow near the Wildwood Avenue entrance to Piedmont Park. It was foraging mid-story in a Live Oak tree with one or more White-crowned Sparrows. I was at the stairs that descend straight downhill towards the playing fields. The sparrows moved off to my left, towards the elementary school. I'm guessing the sparrows move around a fairly large patch so no guarantees where they will be located next.
In breeding bird news, male Anna's Hummingbirds are displaying and there are probably nesting females around, though I didn't succeed in locating any nests today. Oak Titmice seem to be refreshing their territorial boundaries--interesting to hear the counter-singing males match each others' songs for what seems like forever and then, on some secret cue, they both switch to a different song they both know. I also heard singing Song Sparrows, Bewick's Wrens (no surprise), Lesser Goldfinches, and a Hutton's Vireo.
The most confusing behavior I encountered was a female Nuttall's Woodpecker who continually harassed a male for almost half an hour and eventually chased him away. She kept up a quick succession of loud rattle calls, to which the male responded each time with clucks. The female came closer and closer to the male and then started hopping around him, rattling and giving quick side to side bows.According to Birds of the World, this is agonistic behavior, not courting. I have no idea what the dispute was about.
I’m pretty new to birding and newer to this list, but had the very exciting
experience today of watching a red-tailed hawk with some binocs and seeing
it land and then… start fussing with some twigs! Per group rules I won’t
say the exact nest location but it’s close to my home and I’m excited to
(quietly and unobtrusively) observe them daily, hopefully spot some
juveniles in a few months. Feel very fortunate to live in Berkeley and see
raptors almost every day.

*Reply-To:* <vanpierszalowski...>
Hi Birders,
Tomorrow marks the launch of California’s first statewide Breeding Bird
Atlas, a community-powered initiative to document breeding birds across the
state and generate the science needed to guide habitat protection,
restoration, and long-term conservation planning for decades to come.
This landmark effort is being led by *California Bird Atlas*
<https://www.californiabirdatlas.org/> (CBA), an independent nonprofit, in
collaboration with state agencies, thousands of volunteers, and dozens of
partner organizations.
All birders are now officially invited to join the project by visiting the
new *California Bird Atlas eBird website
<https://ebird.org/atlascalifornia/home>*. Simply click “*Join Project*”
(or “Log In to Join Project”) and you will automatically be able to
contribute checklists to the Atlas project.
The Atlas is fully integrated with the eBird mobile app. If you submit
checklists on mobile, this *Quick Start Tutorial video
<https://www.youtube.com/shorts/8Z3kbqiO9rw>* provides a brief overview.
Please visit the *About <https://ebird.org/atlascalifornia/about>* page for
resources, basic guidance, and everything you need to begin contributing to
this statewide initiative.
We encourage *all checklists submitted year-round to be entered through the
Atlas project*, even if they don’t include breeding behavior. While we are
still a few months from peak breeding season, you can learn more about
species with a history of breeding in January in California by reading *this
article <https://ebird.org/atlascalifornia/news/early-breeders-jan>*.
We will be growing our team, expanding resources, and continuing to build
this grassroots movement in the coming months. As we launch, early
donations are especially impactful — supporting training, field tools, and
outreach in the first critical months. We’re a nonprofit, and every
contribution is tax-deductible and genuinely appreciated. If you have the
means, please consider making a gift today to help the Atlas start strong —
your support right now truly matters. *Donate

As Isabelle Reddy and several others have noted, mountain bluebird numbers are wild right now. After last winter when the birds seemed unusually hard to find, they’re back in force at the now-defunct Cedar Mountain Winery. At one point, I did a full 360 sweep while standing amid the vines, and counted 105 individuals. I’ve conservatively estimated 170 which is pleasingly close to the CBC count of 175. Just a glorious experience with a stunning species. The birds don’t always stick around so I would urge folks to hang out with them over the next week or so if possible.
I don’t think Google recognizes Cedar Mountain Winery anymore so aim for Reuss Road, stop about halfway along (say (37.6613708, -121.6654616)) and prepare to bathe in blueness.
Date: 1/7/26 9:19 pm From: Derek via groups.io <dlheins...> Subject: [EBB-Sightings] Eastern Alameda CBC recap from December 19.
The 17th annual Eastern Alameda Christmas Bird Count, originally led by
Rich Cimino and Jeff Miller, was held on Friday, December 19th in pleasant
weather (no pun intended). Our 78 participants finished the day having
found 144 species, a couple below our historical average but the highest
count in the last 6 years. We tallied a total of 25,743 birds, which is
significantly lower than our 30,512 average but higher than the average of
the last 5 years.
We added no new species to our count circle, but did have some notable
sightings. There were 2 Redheads at Poppy Ridge Golf Course, a Common Loon
off El Charro Road, 42 Long-billed Curlews north of I-580 near Livermore
Avenue, and 175 Mountain Bluebirds in one flock near Tesla Road.
Species missed included Cinnamon Teal (second year in a row), Black-crowned
Night Heron, Sora, Common Gallinule, Black-necked Stilt, Lewis’s
Woodpecker, Red-breasted Nuthatch, House Wren, Golden-crowned Kinglet and
Common Yellowthroat.
We had high counts for Greater White-fronted Geese (213), American Pipits
(328), Orange-crowned Warbler (7), Bald Eagle (13), Anna’s Hummingbird
(307), Common Raven (360 versus less than 100 average the first 10 years),
and American Kestrel (122 being higher than our first 10 year average).
Some species with notable low counts:
· 325 Mallards was down from our historical average of 511.
· 158 Ring-necked Ducks; the average our first 10 counts was 330
· 4 Common Goldeneyes ties for lowest count versus historical average
of 24
· 28 Common Mergansers is less than half our historical average
· 129 Wild Turkeys was our lowest count to date
· 40 Double-crested Cormorants was our lowest count versus 220 average
· 19 Great Blue Herons was our lowest count versus 33 average.
· 9 White-tailed Kites continued a low trend; the average of our
first 10 counts was 43.
· We also had lowest ever counts of Sharp-shinned Hawks, Steller’s
Jays and Western Scrub-jays. Other species seeing consistent declines are
Nuttall’s Woodpecker, Loggerhead Shrike, Yellow-billed Magpie, Northern
Mockingbird, Tricolored Blackbird and House Sparrow.
We would like to thank all of the participants and also Lawrence Livermore
Labs, East Bay Regional Parks, San Francisco Public Utilities Commission
and Koopmann Family Ranch for allowing us access to areas normally off
limits.
Date: 1/6/26 9:18 pm From: Alexander Henry via groups.io <awhenry...> Subject: [EBB-Sightings] Heron Bay/Tony Lema/San Lorenzo Creek Mouth Avian Fiesta
This afternoon/evening, Sharon Jue and I visited the Heron Bay/Tony Lema Golf Course area, as accessed from the end of Lewelling Boulevard. There was simply an exceptional level of bird activity, and the outing became arguably one of the best birding sessions either of us have ever had in the East Bay.
When we arrived, the tide was very high (7.5 feet or so), though not quite as high as the king tides of the previous few days (when there were 8+ foot tides in this area). There were many hundreds of shorebirds roosting in ponds in the marshes. This included a Lesser Yellowlegs, as well as several Greater Yellowlegs, over a dozen Long-billed Curlews, a couple dozen Stilts, over 250 Avocets, over 400 Dowitchers, and a few Willets and Calidrids. There were also good numbers of dabbling ducks throughout the marsh, including Shovelers, American Wigeons, Mallards, and Green-winged Teals.
Tony Lema Golf Course was hosting incredible goose diversity and abundance, as least by Alameda County standards. There were over 100 Greater White-fronted Geese and Canada Geese, 50-100 Cackling Geese, and 11 “white geese”. The variety of “white geese” was quite nice, and fun to study. There were 8 Snow Geese, a mixture of adults and juveniles and one juvenile “Blue Goose”. There was also 1 clear Ross’s, 1 probably Ross’s, and 1 possibly a hybrid. It seemed like a bit of a spectrum. Were we just overanalyzing 3 Ross’s Geese? Definitely an interesting and somewhat confusing flock to study.
There were also 3 Blue-winged Teal and some Cinnamon Teals in the big golf course pond.
By the time the sun was setting, the tide had fallen quite a bit, and expansive mudflats around the San Lorenzo Creek Mouth were beginning to be exposed. Thousands of shorebirds and gulls coated these mudflats; the number of gulls seemed at least 5 times as many as normal.
Around this time, rail activity picked up quite a bit. A dusk chorus of Ridgway’s Rails and Soras filled the air, with the occasional Virginia Rail grunting. We didn’t see any Virginia Rails, but we saw 3 species of rail plus Coots ;). Some sparrows were also somewhat active around dusk, and we heard a Swamp Sparrow calling at dusk. A Barn Owl was flying over the marshes at dusk while a Snipe flew around calling.
Overall, it just seemed incredibly birdy. The gulls at San Lorenzo Creek Mouth and geese at Tony Lema Golf Course especially seemed exceptional. Hoping this area can get some more coverage in the coming days or weeks! And would love to hear other people’s opinions on the “white geese” flock.

As some of you may recall, Saturday was a very wet day, the second in a row for our fledgling five-year old Richmond CBC circle. But in defiance of the weather forecast, a record 201 enthusiastic birders participated, including a group of local Girl Scouts. Over half of our birders were new participants to the Richmond CBC and we hope they keep joining us for future counts!
As preliminary result, we have logged 178 species,which is above our count average, but noteworthy given the most challenging conditions we've faced to date:
Regarding the birds we saw on Saturday:
- We had 7 new species bringing our count day life list to 204: Long-tailed Duck and Red-necked Grebe at Point Molate, Violet-green Swallow north of San Pablo Reservoir, Northern Rough-winged Swallow at Dotson Marsh, Vega Gull at Landfill Loop, Tennessee Warbler and Summer Tanager continuing at Booker T Anderson Park. Noah Arthur ID'd the Vega Gull, the third ever recorded in Contra Costa County (he had one at Miller/Knox in 2013).
- Some other notable sightings were our only Ring-necked Pheasant, Caspian Tern and Short-eared Owl at Mare Island; a Snowy Plover at Point Pinole; 67 Black Skimmers at Meeker Slough; a Black Rail at Landfill Loop; a Rock Wren at Point Molate; a Pacific Loon at Richmond Marina. Our boat only made it out to Brooks Island before returning to port due to the blustering weather, but they did spot a Heermann's Gull among all the Brown Pelicans.
- Looks like we're down to one Black Scoter at Richmond Marina; Bob Lewis noted that it seems to be mournfully whistling more than usual.
- Every year has its missing species and this year was no exception. One would think all the recent rains would enhance habitats for waterfowl, but some of our biggest misses were Cackling Goose, Wood Duck, Blue-winged Teal and Cinnamon Teal. We also did not see Burrowing Owl or Pine Siskin, but siskins haven't been seen in the East Bay this winter.
- I would say the most noteworthy count was of Band-tailed Pigeons, but that might be a theme across our local CBC's. Forest Chapman's group hiking Crockett Hills Regional Park logged 938, the highest count in eBird history for a single checklist in Contra Costa County. We totaled around 2,200 for the day.
- Trends are a little difficult to interpret based on five years of the count with inconsistent weather and tides, so not much to report here. It should be noted that Bushtits, which won last year's award for consistent counts, must love to dance in the rain as the 784 counted were 30% above normal. The 1,504 crown sparrows were about 40% less than normal, with towhees also down by roughly the same proportion. American Robins were in abundance with 1,919 being almost triple our previous average.
In addition to all the great birds we found on Saturday, birders have also a few more count week species (Wednesday Dec 31 through tomorrow, January 6): Cackling Goose, Short-billed Dowitcher, Common Murre, Lesser Black-backed Gull, American Redstart and Rose-breasted Grosbeak. If you find something interesting in the circle tomorrow that might add to our list, email Derek.
This year's count day really demonstrated the resilience of our birding community. We didn't let the weather dampen our spirits as we supported this important international community science project. Golden Gate Bird Alliance initiated this count circle to bring attention to birds in Richmond and the local communities, and we hope to strengthen this bond in the years to come by encouraging communities in the count circle to celebrate our collective love for birds and the habitats we share.
Thank you everyone for your support in this year's count, and we can't wait to see you all again next year!

Ed,
Your big year is truly an accomplishment. It’s impressive by any measure,
but especially for someone who started relatively recently!
But more than the total, I appreciate the thoughtful approach you bring to
birding; like you’re focused on enjoying the birds (plus their ecology and
surroundings), and not only on the number. The number is impressive, but
the approach is what counts most in my book.
Speaking of books, we’ll all look forward to the latest book when it’s out.

Date: 1/1/26 7:37 pm From: Bruce Mast via groups.io <cathrasher4...> Subject: Re: [EBB-Sightings] A Year of Alameda Birding: 2025
A hearty congratulations to Ed for a truly amazing big year! It's worth
noting that Ed's tally is the highest annual total for Alameda County that
has been published on eBird. I'm also pretty confident that there are no
higher annual totals from the pre-eBird era. Well done!

Happy New Year, East Bay!

Date: 1/1/26 9:01 am From: Ed Yong via groups.io <edyong209...> Subject: [EBB-Sightings] A Year of Alameda Birding: 2025
Happy new year, everyone.
2025 was a deeply troubled year, but birding, as always, provided a salve. Some of you know that I moved to the Bay Area in 2023, feel deeply into birding that year, and spent 2024 trying to see as many birds as I could in my home county of Alameda. I initially figured that in 2025, I’d be more limited in my ability to bird locally because I had a book to write and a lot of travel to do. But as it happened, I successfully finished the book (out spring ‘27) and somehow managed to find a lot of birds—289 in total.
Chasing birds is just one of many ways of birding, and a silly and sometimes maddening game—but also an extremely fun and rewarding one. And for a baby birder, it’s an absolutely phenomenal learning experience. It forces you to pore over the minutiae of identification, to practice ear-birding, to understand and predict bird behavior, to explore a wide variety of hotspots and habitats, to pay close attention to seasonal and tidal cycles, to plug yourself into the local community both human and non-human, to learn to differentiate solid reports from dubious ones, and, above all else, to spend lots of hours in the field. And after spending 2024 doing all of the above, 2025 felt richer, easier, and more joyful. I felt like I had a substantially better understanding of both the land and the birds, and that I was started to recognize the birds instead of just identifying them.
2025 was also an amazing year for Alameda. We had multiple sightings of some great migrants, including common terns, pectoral and solitary sandpipers, chestnut-sided and palm warblers, Pacific golden-plovers, lesser black-backed gulls, clay-colored and Brewer’s sparrows, Ross’s geese, and apparently three separate black-chinned hummingbirds at Creekside. From mid-October, fall migration delivered a two-month streak of absolute bangers, including a sharp-tailed sandpiper seen at close range in perfect light, a Leach’s storm-petrel viewed from shore, a red-naped sapsucker and a bar-tailed godwit (yay!) who both hung around for ages, a black-throated green warbler in Estuary Park of all places, a yellow-billed loon who turned Crab Cove into Crabless Cove, a rock sandpiper who led to calls to surveyors’ offices, and a green-tailed towhee who adopted a pink laundry basket. And let’s not forget the big trend of 2025, which was birds showing up in the worst possible habitats. Consider the American dipper who spent an evening at the tiniest creek at Lake Temescal, the northern waterthrush of Middle Harbor who hung out next to a decaying seal carcass, the Townsend’s solitaire at MLK who didn’t get the memo about junipers and mountains, and the Cocos booby who decided to land in the middle of the lawn in Crab Cove. The birds were all over the place. So, apparently, was I.
Here are the headlines, with all numbers referring to species totals:
* *Total Alameda bird count:* 289, beating my total from last year by 9.
* *New county birds:* 20
* *Lifers:* 7 (Cocos booby, Townsend’s solitaire, long-eared owl, Baird’s sandpiper, Leach’s storm-petrel, tundra swan, rock sandpiper, and last year’s nemesis, the black rail)
* *Birds documented with either photos or recordings:* 286, which was everything except parasitic jaeger (too far and fast), scaly-breasted munia (flyover, tho technically I have a rubbish recording with one call), and pigeon guillemot (no battery in camera, gnnnh)
* *Rarities* (defined as birds that eBird flags as rare throughout the year ): 58
* *Rarities first found by me:* 8 (blue grosbeak, pigeon guillemot, parasitic jaeger, pectoral sandpiper, black scoter, Brewer’s sparrow, Costa’s hummingbird, bar-tailed godwit)
* *Misses* (i.e. reviewer-confirmed species seen by others in Alameda): Only 14, which is wild to me, and almost all were flyovers, feeder visitors, one-hit wonders, or birds whose records were initially withheld.
I don’t think you can really compare people’s numbers since everyone has their own rules for their lists. For the sake of transparency, here are mine:
* *The list reflects your position.* Some folks only count birds that are physically in the county ; I’m in the camp that counts the birds they see from the county. This is consistent with eBird’s guidelines but more importantly, it better reflects what I think birding is about. Censusing birds within an abstract, human, geopolitical boundary is, frankly, not it. For me, birding is an act of extending your senses as far as possible to appreciate the living world around you. As such, an egocentric frame of reference just makes more sense. You plant yourself in place and watch the birds as they go where they like. (People who feel differently can dock harlequin duck from my total, and potentially other seawatched birds.)
* *No playback.* If birders near me ask to use it, I won’t object, but I won’t use it myself. Birds are a gift, and playback feels like greedily snatching that gift instead of positioning yourself to receive it.
* *Heard-only counts.* Birding is a multisensory affair, and there are many species I’d rather hear than see. But I try to get a recording of all heard-only birds to check the IDs. Merlin is helpful, but confirms nothing. HO birds this year included common poorwill, black rail, winter wren, yellow-breasted chat, and owls: northern pygmy, northern saw-whet, and western screech.
* *Try to get proper documentation.* No to written description, sketches, or anything else that is first processed by your senses, fallible and bias-prone as they are. Yes to photos and recordings.
* *All reports confirmed by eBird reviewers.* Self-explanatory. Thanks to the reviewers, and especially to Teale Fristoe for tirelessly keeping the county data’s shiny.
* *Usual eBird rules:* No dead birds, escapees, or exotics. I don’t count the recurring Swinhoe’s white-eyes of Creekside Park even though they count in my heart. And I don’t count hybrids even though, as Megan Jankowski says, they should count three times.
Huge thanks to everyone who I spent time in the field with; friends in my groupchats; the many people who found cool rarities (with a special shout-out to Sharon Jue who found so many ); everyone who shared reports of East Bay birds and especially people who did so quickly; and every single person who has worked to conserve the places that we and the birds rely on.
On that final note, and in the spirit of giving back to nature as much as we take from it, I have donated $5 per species to the Golden Gate Bird Alliance.
Happy new year, everyone. Let hope, as always, be the thing with feathers.

Late but satisfied Summer Tanager pursuit. Also a Red-breasted Sapsucker (plus 2 pairs of Downy and Nuttalls) and other stuff. I missed a credible sighting of the Varied Thrush that Steve Powell saw today, and the Red-shouldered Hawk was awol. The Eucalyptus has begun to bloom, so the Yellow-Rumped Warblers were everywhere.

Hi all,
Teri Wills is reporting a male Tufted Duck at Martinez Reg. Shoreline. Teri left it ambiguous if she think it is “for sure” or not (issues with hybrids etc.) but the one photo I saw looks pretty promising.
Date: 12/25/25 5:00 pm From: Richard Bradus via groups.io <grizzledjay...> Subject: Re: [EBB-Sightings] Possible Lucy’s at Booker - details
Apologies for my somewhat cryptic post - a Merry (if stormy and belated) Christmas to all.
The bird was seen at Booker T Anderson Park in Richmond, same place as the continuing Summer Tanager and Tennessee Warbler.
I spotted it initially around perhaps 11:50am when it perched in the open for a minute or so on a small willow branch in the row of trees along the creek, and first thought it looked like a bit like a Bushtit, but the tail was not so long and it had a narrow, warbler beak. I got Nat Smale on it but when he started to raise his camera to try to get a photo it flew off to the south toward the row of eucs and I lost it (and I don't think Nat got a sufficient view to be comfortable of the ID, particularly as the bird was somewhat backlit).
Later (perhaps 12:45pm or so), while searching again for the tanager, etc. it appeared briefly high up in the trees near where the tanager had been and was seen by Kevin Hintsa and his buddy (sorry, I forgot your name) but quickly flew off, again south toward the tall eucs and we were unable to follow it.
The bird was striking in its plainness; it was gray overall, with whitish underparts, lacking any streaking on the breast or sides or any discernible markings around the face. My view was straight on but looking up mostly at the underside, so I did not get a view of the crown or uppertail to ascertain for any rufous coloration. It was smaller and appeared a bit more plump than the Yellow-rumps, with a thin, pointed warbler beak (not like a Bushtit or Goldfinch) and lacked white eye ring or black wing patch as would be expected of a Kinglet (plus it held its position for much longer than a Kinglet or vireo would).
I'm reasonably confident of the ID as a Lucy's Warbler (can't think of anything else it could have been) but have refrained from formally submitting as such since the other observers only got brief views and there is no photo documentation. With the weather being as it is, we can only hope that it stuck around; like the Tennessee Warbler (for me a bit difficult to spot), patience and determined search may well be necessary.
Good luck! (And thank you Jack Hayden for finding the tanager and bringing us to this spot).

The report came from Booker T Anderson Park in Richmond, but it hasn't been
confirmed. I was there yesterday afternoon with a few other birders. We saw
the Summer Tanager that has been continuing there, and another birder saw
the Tennessee Warbler, but we were never able to find anything resembling a
Lucy's Warbler.

Tuesday, with no rain in the forecast, I went out to look for the Summer Tanager originally spotted by Jack Hayden at Booker T Anderson park. When I arrived a group of birders had spotted it in the trees along the creek and within a couple of minutes I had a photo. Amazing. We spotted it several times and with some help from Sam Zuckerman I got a photo of the Tanager with small bee in its bill. A Lifer for me. Now about seeing one in its summer colors.

Date: 12/22/25 2:17 pm From: Chris Ortega via groups.io <chrisorte9a...> Subject: [EBB-Sightings] Central CCC CBC Wrap Up
The 2025 Mount Diablo Bird Alliance Central Contra Costa Christmas Bird
Count took place on December 20th, the latest in the year this count ever
happens due to the official CBC window. It saw 73 volunteers brave fog and
light rain in most areas off and on throughout the day. Collectively, they
observed 155 species, which is 6 above average for the count over the past
25 years, and 7 above last year's count, which took place in abysmal
conditions. This is perhaps especially impressive given we did not have
access to one of our most productive areas this year at the Military Ocean
Terminal Concord (MOTCO).
While there were no birds found entirely new to the count, a Caspian Tern
(seen by Harrison Allen-Suter, Ray Witbeck, Nat Weber, Fred Werner, Jon
Rosenfield, and Bill Chilson) at Mallard Reservoir is the first seen since
2017 and only the second in the last 25 years. A Northern Rough-winged
Swallow (Matt Tarlach, Alan Krakauer, Rosita Ortega) back for the second
year in a row at Central Contra Costa Sanitary District is also a count
second. 2 Common Loons at Mallard Reservoir are a third-time occurrence on
the count and the new high count for that species.
Slightly less rare, but still exciting were Short-billed Dowitchers (Matt,
Alan, Rosita, and Harrison, Ray, Nat, Fred, Jon, Bill) seen at both
McNabney Marsh and Mallard Reservoir and a Redhead (Ted Robertson) found at
Shell Pond. Shoutout also to the dozens of saves (species only recorded by
one team) on this count including Tundra Swan, Northern Pintail, American
Bittern, Bald Eagle (all observed by Ted), Wood Duck (Chris & Teri Wills,
Sandy Ritchie, Joy Dardin), Blue-winged Teal, Barrow’s Goldeneye, Common
Merganser, Marbled Godwit, Willet, Glaucous-winged Gull, Iceland Gull,
Osprey, Peregrine Falcon (Harrison, Ray, Nat, Fred, Jon, Bill), Band-tailed
Pigeon, Burrowing Owl (Krista Vossekuil, JD Bergeron, Cheryl Reynolds,
Randy Harrell, Travis Harrell) Black Rail, Horned Lark, Tricolored
Blackbird (Forest Chapman), American Barn Owl (Alan Bade, Susana de
Trapaga, Maren Smith), Red-breasted Nuthatch (Robert Raffel), Canyon Wren
(Joel Herr), and Brown-headed Cowbird (Matt, Alan, Rosita).
There was one exceptionally glaring miss for the count: Golden Eagle. Going
back at least to 1994, that species has never been absent from this count
until now. The fog may have had something to do with that, but other years
have had unfavorable weather, too. Beyond the eagles, it was pretty
surprising not to have any Purple Finches or Lesser Scaups observed since
they have been recorded in more than 80% of past counts. Spotted Sandpiper,
Ferruginous Hawk, Bell’s Sparrow, Prairie Falcon, Pine Siskin, Surf Scoter,
Horned Grebe, Northern House Wren, and Golden-crowned Kinglet round out the
rest of the misses for species that had occurred on at least half of the
last 25 counts.
In terms of overall numbers, roughly half of the species counts were below
historical average and a quarter were above. That said, there were 10 new
high counts, notably including two shorebirds with 508 Long-billed
Dowitchers (26% higher than the previous high) and 458 Western Sandpipers
(154% higher). 7 Orange-crowned Warblers is 75% higher than the previous
high, with all of them coming from local parks in Pittsburg, many of which
have not traditionally been covered by this count. 27 Rufous-crowned
Sparrows is a 59% increase, and 33 California Thrashers is a 50% increase.
4 species recorded new low counts including just 5 Great Blue Herons (down
from a previous low of 7), 3 Loggerhead Shrikes (4), and 9 Northern
Harriers (11) with the harriers likely reflecting the absence of MOTCO data
this year.
There were several first-time participants as well as a pair of first-time
co-compilers, neither of whom were well enough to participate in the count,
itself! This year also saw the return of an in-person countdown dinner for
the first time since COVID-19. Thanks be to Ted Robertson and Matt Tarlach
for running the countdown dinner in the compilers' absence.
Please note that although this report has been written as though the
numbers are final, some minor changes will likely still happen as the last
bits of data come in, so check back on the eBird trip report here
https://ebird.org/tripreport/445034 to see the latest results. Everything
has to be finalized and submitted to National Audubon by the end of
February.
Good Birding,

Apparently there is something of a Short-eared Owl irruption happening in the Bay Area and Sacramento Valley currently.
This brings up a few things in my mind. This isn’t a “heads up, they’re here, go chase them!” message - if anything keep an eye out for them but leave them alone as much as possible! Just a few things to think about.
1) ID. Long-eared Owls and Short-eared Owls can look pretty similar, especially when flying around in the distance in low light conditions. And there is certainly some habitat overlap, at least at this time of year. Please just check and make sure.
2) Ethics. Owls are sensitive to disturbance, please respect them and give them some space. Different individuals have different levels of experience and comfort with humans, and you never know if an individual bird will be accommodating or will be stressed by your presence until you actually interact with that individual. They’ll be more likely to stick around for the winter, safe and happy, if they’re given plenty of space and not thronged by admirers. Just stand on the road and watch them forage in the distance, don’t chase them around at close range trying to get perfect photos.
3) Snowy Owl irruption? Might sound crazy but it’s worth thinking about. There’s a Snowy Owl on the central Oregon coast right now, in addition to Washington, Idaho, and Montana. It’s not inconceivable that one could show up in Northern California. And hey, we’ve already had some arctic visitors this fall. Even though it’s wildly improbable, seems worth thinking about.

The 26th annual EAST CONTRA COSTA Christmas Bird Count kicked off December
17th, 2025 with high overcast, fog, and light to moderate rain across the
circle. The day finished with partially overcast to sunny skies and low
wind, particularly nice as Tuesday afternoon was the first sunshine some
parts of the count circle had seen in 24 days. A few over 40 bird counters
ended the day observing 157 species, which beats our previous record total
of 155 species by two. Three species new to the count (!) were two
Blue-winged Teal at Big Break Regional Shoreline (Mona Lange, Sammy Cowell,
Nancy Salsig, Carol Pachl), a California Thrasher at Round Valley (Scott
and Claudia Hein, Joel Herr, Bruce and Joan Hamilton) and a Lawrence’s
Goldfinch at Clifton Court Forebay (Forest Chapman). The only rarities for
Contra Costa County were one “Lesser” Canada Goose at Holland Tract (Ethan
Monk, Dominik Mosur, Ted Robertson, Jeff Manker) and a Rough-legged Hawk at
Clifton Court Forebay (Forest Chapman). The hawk has been found on 13
previous counts, but is now less than annual on the count and in the
county, last being seen in the county and on the count in Dec. 2022.
Species found recorded in fewer than 33% of previous counts included
Cinnamon Teal at Big Break Reg. Shoreline (Mona Lange, Sammy Cowell, Nancy
Salsig, Carol Pachl, 3 previous count records), Chipping Sparrow at the
intersection of Payne x Walnut Blvd. (Ethan Monk, 3 prev. count records),
Canyon Wren at Round Valley (Scott and Claudia Hein, Joel Herr, Bruce and
Joan Hamilton, 3 prev.), Chestnut-backed Chickadee a species recently
recognized to be present on the oaky stretches of Marsh Creek in Brentwood
(Robert Raffel, Derek Heins, Bill Kezer, Lisa Weiss, Rosemary Nishikawa,
5), Redhead at Clifton Court Forebay (Forest Chapman, 5), Black-throated
Gray Warbler in Los Vaqueros (Maren Smith, Dan Sandri, Arnold Joe, Fernanda
Franco-Ferrera, Dan Fitzgerald, Joy Dardin, 7), Common Loon at Dutch Slough
Restoration Area (Jason Riggio, Isaac Aronow, Maggie Bourda, Amanda Kindel,
7), and Red-breasted Merganser at Clifton Court Forebay (Forest Chapman,
7). Also on this list is Mute Swan, having previously been found in 5 of
the count’s 25 previous years. On this year’s count, 49 Mute Swans were
found in four of the count’s ten different areas. The previous record high
count of Mute Swan for the count was 17 birds, found last year. The only
two bird species missed that have been seen on more than half of all
previous counts are Horned Grebe (records 14 previous years) and
Yellow-billed Magpie (records 14 previous years). The grebe is just
unlucky; on the other hand, magpies are now extirpated from Contra Costa
County and can no longer be found in the areas around the towns of
Knightsen or Byron. Similarly in decline, the preliminary count of
Collared-Dove is 56; the lowest total since 2012. With only 3 recorded,
this was the second worst year for Tricolored Blackbird in the count’s
history, with the record worst being 1 in 2020. The average found per year
in this circle sat at 624.2 prior to this count. The preliminary count of
Shrike is 19, the lowest in count history, and on the up, with over 790
preliminarily reported, Yellow-rumped Warblers were at their highest number
ever. The previous high count was 781 in 2005. The ten year average is
476.8. 80 Common Gallinule breaks the previous record of 67, with 63 at Big
Break alone!
Thank you to everyone who helped with the count. And until next year-

In regard to the question about the precise location of the County line, I reached out to the County Surveyors with Contra Costa County Public Works Department. Jim Stein, County Surveyor Emeritus, plotted the County line in the the department's current orthophotography and sent me the attached image to depict the location. (I hope the PDF image attaches. I've never tried this before in the Group.)
Quoting Jim, he explained that the line, as located, " is based on CalTrans survey monumentation mapping. Our line is nearly identical to the Contra Costa County Assessor line. The line is approximately 130’ north of the center of El Cerrito Creek, measured parallel to the freeway."

Looking for the snipe with no luck but saw 20 white-fronted geese and a single Ross’s goose in the pond behind the swim complex. I believe they are the same geese I saw at Wagner Ranch School during Sunday’s bird count.

It usually scurries deeper into the reeds when spotted, but this afternoon it was hanging out in the open for about 15 minutes before flying away. It's seen on the Nature Lake near the island, by the NW end of the new wooden fence at the edge of the reeds.
