[CALBIRDS] California’s First Statewide Breeding Bird Atlas Launches Tomorrow, January 1, 2026

9:23 pm

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 (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. 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 provides a brief overview.
 
If you use the website, you can submit checklists to the Atlas project by clicking Submit from the CBA eBird site.
 
Please visit the 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.
 
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 here.
 
With gratitude and excitement for what we’ll build together,
 
Van Pierszalowski
Executive Director,
California Bird Atlas (CBA)

Bald Eagle – San Elijo

10:52 am

Bald eagle just seen a 1040 in the pine tree at 33.00357° N, 117.26781° W and flew east, past I5 freeway. I’m going around the corner to see if I can find it again, but it could’ve continued flying further.

New Year, New Weekly Hotspots! (Jan 1 through Jan 7, 2026)

9:11 pm

Season’s greetings, fellow SD birders!
As John Bruin indicated in his last hotspot missive of 2025, I will be taking over weekly hotspot duties for 2026.
First, I’d like to thank John for launching this project and his tireless effort in keeping it going for well over a year!
Thanks to John and all of you who went out to these hotspots, together we greatly increased calendar week coverage of San Diego’s most popular hotspots!
I just reran stats and we now have 30 hotspots needing only 1 week to complete the bar charts, and 70 more that need 2-9 weeks. That works out to roughly 5-10 hotspots most weeks.
Since that’s not very many compared to what we’ve been doing in 2025, I’m modifying the hotspot selection process so that we have 30 hotspots suggested for any given week.
Since the goal here is to improve coverage of hotspots throughout the year, I’m filling the remainder of the 30 hotspot quota each week by including additional “gap” hotspots in the weekly list that have not been birded in any of the three weeks including and immediately surrounding the current week. So, for example, for the first week of January, I am including 25 hotspots that have been birded neither in the last week of December nor the first two weeks of January (of any year). These “gap” hotspots are prioritized by fewest missing weeks (this metric will be noted as “gap” in the maps going forward – if you click/tap on hotspot pins on the linked map, you can see this and more). These hotspots will be in a separate layer in the map – you can toggle each layer on and off as you prefer.
Here’s to a birdy 2026!
Hotspots nearing bar chart completion:

Agua Hedionda Lagoon–east end
Hilleary Park
Laguna Mtns.–Upper Kitchen Creek Rd.
Lake Sutherland
Los Penasquitos Canyon Preserve–Carson’s Crossing area
Torrey Hills Mesa

Hotspots with 3+ week bar chart gaps:

Mt. Hope Cemetery
Anza-Borrego Desert SP–Old Vallecito Ranch
City Heights Community Park
Loveland Reservoir
Oasis Spring
Discovery Creek Trail
Otay Mountain Wilderness
Swan Canyon
Pacific Crest Trail–east of Kitchen Creek Rd.
Santa Margarita Ecological Reserve (Restricted Access)
Palomar Mtn.–Doane Valley CG
Spooners Mesa
Bonsall–Old River Rd.
Poway–Budwin Lane riparian
Sweetwater Community Gardens
Otay River Valley–east of 125
Old Highway 80–west of Wildwood Glen
Coronado Cays–park & residential
Cactus County Park
Jess Martin Park
Anza-Borrego Desert SP–Box Canyon
Ramona Grasslands–Old Survey Road 97
Poway–Sycamore Cyn Rd at Garden Rd
Ramona Oaks Park

P.S. If you don’t see a message here from me before each bar chart week begins (1st, 8th, 15th of each month), please prod me! I’ll try to be consistent, but I might occasionally become distracted and forget!

2025 South End Salton Sea Christmas Bird Count summary

10:15 am


The 2025 South End of the Salton Sea Christmas Bird Count took place on Tuesday, December 16. I am grateful to Raz Shafique-Sabir and the staff of the Sonny Bono Salton Sea National Wildlife Refuge for hosting our count and for helping
us to cover sections of the Refuge. I also want to thank Clarissa Diaz at Kiewit for escorting me through the Species Conservation Habitat (SCH) Project at the mouth of the New River. This is a restoration area that is off limits to the public – I was saddened
to hear of previous instances of birders trespassing into the project area, and I wish to underscore that this area is currently completely off limits to the public.

 

We counted under ideal conditions, clear and calm, with temperatures ranging from the mid 40s at daybreak to the mid to upper 70s by the afternoon. We had 35 participants, the most since 2013, and I want to specifically thank Lesley Handa
for coordinating the participation of nearly a dozen counters that covered Sections 7 and 8.

We tallied 131,748 birds representing 156 species, with 149 species on count day. This is the most species observed since 2015, correlating with Salton Sea’s ongoing receding/decline. I once plotted count totals since 2000 back in 2023,
drawing a regression line through the scatterplot at that point in time. The plot below puts our showing against other years in nice perspective:

 

 

The SCH Project is working – Samuel Bressler and Clarissa and I counted nearly 23,000 birds there, adding a number of species to our total. The project seems to be catalyzing bird activity in other parts of the count circle as well,
with Raz amassing an excellent gull count at the Red Hill Area/Alamo River delta, including 2 Western Gulls, 200 American Herring Gulls, over 1,000 California Gulls, over 2,000 Ring-billed Gulls, 100 Bonaparte’s Gulls, and 3,000 gulls left unidentified.

 

Al DeMartini and Terry Brauner found the birds of the count – 2 Cave Swallows at the Calipatria Algae Farm in Section 3. Many of us twitched these in the afternoon, following our CBC lunch and species countdown. Two Cave Swallows soon became
three, and then in following days, as other California birders twitched the swallows, three became 11, and then 11 eventually became 24 Cave Swallows by December 21, a magical event. Then Loren Wright, Dessi Sieburth, Logan Kahle, and Chris Dean reported count
week Bank Swallow, Lapland Longspur, and Thick-billed Longspur from the site on December 17, species that we miss far more often than we make.

 

Christian Schwartz and Grigory Heaton had an excellent day covering Niland, with Christian finding a Summer Tanager, Tropical Kingbird, and Cassin’s Kingbird, and Grigory finding an Indigo Bunting – all species that have only appeared in
a handful of previous counts each. Grigory and Matt Brady (covering Calipatria) each found a Northern Parula, only our 4th count with the species and the first they have been reported on a count since 1989. Finally, Guy McCaskie and Chris Dean found
a Laughing Gull in Section 5, the first time the species has been encountered on a count since 2011.

Swainson’s Thrush in Encinitas

5:18 am

Yesterday, the 29th, I had a Swainson’s Thrush along the back edge of Encinitas Community Park. Photos in my eBird report. This is the fourth winter record of Swainson’s in the county, with previous records from Coronado, Chula Vista, and Carlsbad. This bird looks unsteady when it landed on low branches on multiple occasions, which suggests it may be slightly injured in some way or otherwise not well, which would help explain why it is still here in late December. It was finding food OK both in the leaf litter and eating a few toyon berries. A Hermit Thrush is present nearby as well. Hopefully it can make it to the Rancho Santa Fe CBC this coming Saturday.
Elsewhere in Encinitas, there was a Green-tailed Towhee bordering a private HOA park. Green-taileds are much rarer in North County than in southern South County.
