Hi Everyone, This is a quick reminder that the next California Bird Atlas Town Hall Q & A sessions is TONIGHT, April 16, at 7 pm. This is a great opportunity to hear the status of our efforts, to ask questions, and how to look for evidence of breeding activity. The Town Hall will be on Zoom. To register for the Zoom meeting, go to: https://www.californiabirdatlas.org/events/california-bird-atlas-town-hall-april And then click on "Register via Zoom." We hope you'll join us!

It seemed slow at Sand Dune until about 1PM when merlin heard a Calliope Hummingbird that I never saw and then an all blue bird that was neither a mountain bluebird nor a blue grosbeak but rather an Indigo Bunting.

Date: 4/13/26 11:00 pm From: David Koeppel via groups.io <davkofilms...> Subject: [LACoBirds] East San Gabriel Mountains preview
While E. Blue Ridge Road in the San Gabriel Mountains remains closed, the section of the Pacific Crest Trail that runs alongside it offers a user-friendly means of accessing the ridge and the wilderness beyond. By parking at the Inspiration Point parking lot on the opposite side of Angeles Crest Highway, I easily walked the half mile to the fire road that, in past springs, has yielded a good mix of upper montane species. Even on a blustery morning cut short by snow flurries, sleet, dense fog, and wind, a flourish of birds that included Hairy Woodpecker, Mountain Chickadee, White-breasted Nuthatch, Fox Sparrow, and Spotted Towhee managed to liven up the fire-ravaged bleakness of the surroundings. Amazingly, most of the white firs and about 60% of the Jeffrey pines in the first stand along the fire road withstood the devastation, so I encourage Atlasers living in closer proximity to the San Gabriel Mountains than myself to check back here in May, June, and July. Maybe there is hope for the Nashville Warblers, Flammulated Owls, and other standouts known to have bred in this area.

Hello birders,
Today, April 12, 2026, I photographed two Common Loons flying northwest over Descanso Gardens. It appeared to be a new species (# 207) at that location.
Date: 4/11/26 9:50 pm From: Lance Benner via groups.io <lbenner...> Subject: [LACoBirds] Bird Atlas Update for Los Angeles County: 2026 April 11
Hi Everyone, Here's another update on progress with the California Bird Atlas in Los Angeles County. These are results as of the morning of 2026 April 11. LA County eBird Atlasers: 526 eBird Checklists: 8027 Atlas effort: 6075 hoursAtlas blocks with data: 328 (76% of the total)Species with a breeding code: 222 Species with breeding confirmed: 110 32 species have been confirmed in at least 10 blocks: 14 Canada Goose 21 Mallard 16 Mourning Dove 28 Anna's Hummingbird 36 Allen's Hummingbird 13 Great Blue Heron 14 Cooper's Hawk 13 Red-shouldered Hawk 37 Red-tailed Hawk 21 Great Horned Owl 35 Black Phoebe 16 Cassin's Kingbird 20 California Scrub-Jay 39 American Crow 89 Common Raven 21 Oak Titmouse 12 Cliff Swallow 65 Bushtit 12 Northern House Wren 23 Bewick's Wren 35 European Starling 16 Northern Mockingbird 19 Western Bluebird 14 Scaly-Breasted Munia 51 House Sparrow 73 House Finch 18 Lesser Goldfinch 20 Dark-eyed Junco 26 Song Sparrow 34 California Towhee 10 Hooded Oriole 10 Orange-crowned Warbler The number on the left gives the number of blocks where each species has been confirmed. The number of blocks with new confirmations of hummingbird and red-shouldered hawks has slowed considerably, which is expected given that these species nest early, but several other species, such as Cooper's hawk, hooded oriole, orange-crowned warbler, and cliff swallow have picked up. Common Ravens, house finches, and bushtits have been confirmed in the most blocks. Los Angeles County blocks where breeding has been confirmed for at least 10 species: 16 Baldwin Park NW 18 Burbank SE 10 El Monte CE 16 El Monte SE 13 Glendora SE 14 Hollywood CE 26 Hollywood NE 13 Hollywood SE 10 Juniper Hills CW 15 Long Beach CE 12 Long Beach CW 10 Long Beach SE 15 Los Alamitos CW 14 Los Alamitos NW 17 Los Angeles CW 10 Los Angeles NE 20 Los Angeles NW 20 Mount Wilson SE 21 Mount Wilson SW 17 Newhall CW 18 Ontario NW 37 Pasadena CE 26 Pasadena CW 18 Pasadena SE 10 Rosamond CW 21 San Dimas CE 32 San Dimas NE 14 San Fernando SE 10 Val Verde SE 13 Valyermo NW 24 Van Nuys CW 19 Venice NE 10 Warm Springs Mountain CW 38 Whittier SE Here the number gives the number of species in that block that have been confirmed. Note that 30+ species have been confirmed breeding in three blocks: Pasadena CE (37), San Dimas NE (32), and Whittier SE (38). Two weeks ago there were 21 blocks on this list. Now there are 34. We are making progress! Blocks with at least 50 species with breeding codes: 54 Baldwin Park NW 77 Burbank SE 59 El Monte SE 58 Hollywood NE 55 Lake Hughes CW 50 Los Alamitos CW 65 Los Angeles NW 64 Mount Wilson CE 53 Mount Wilson CW 53 Mount Wilson SE 62 Mount Wilson SW 53 Ontario NW 75 Pasadena CE 60 Pasadena CW 51 Pasadena NE 64 Pasadena SE 74 San Dimas NE 81 San Fernando SE 56 Valyermo NW 65 Van Nuys CW 58 Venice NE 62 Whittier SEFor comparison, two weeks ago 14 blocks had at least 50 coded species. Now the total is 22. The numbers in some of these blocks are approaching levels from the first Los Angeles County Bird Atlas from 1995-1999. Some are already higher. Given results from the previous Los Angeles County Bird Atlas, we should be able to push the number of coded species above 50 for most of the blocks along the coastal slope, Santa Monica Mountains, valleys, and in the mountains, although perhaps not in the urban core of Los Angeles. With some effort, many blocks in the Antelope Valley might reach ~30 species. Right now is an excellent time to see evidence of breeding. In the past ten days or so, I've seen numerous birds carrying nesting material, carrying food, feeding young, and a few occupied nests. My own neighborhood has been far more productive than I expected. To date, and in no particular order, I've confirmed breeding for the following species:Bewick's Wren, Common Raven, Oak Titmouse, Anna's Hummingbird, Northern Mockingbird, Red-whiskered Bulbul, European Starling, Bushtit, Dark-eyed Junco, House Finch, and Lesser Goldfinch. So please check your neighborhood! To see how much effort has been contributed (number of hours), number of species coded, confirmed, complete checklists, etc. go to: https://ebird.org/atlascalifornia/effortmap Once you bring up the map, you can zoom in to any particular part of the state, and if you click on each rectangle, you can see a summary of effort and species reported there. Although we're making really good progress in Los Angeles County, we still have a long way to go. There are 434 blocks in the county and more than 100 still have zero data. If you're looking for good areas to contribute, check the map discussed above, zoom in on a block where there's little or no effort, and go birding there. We hope you'll join us!

Date: 4/10/26 11:35 am From: Maya Rodriguez via groups.io <mayajailyn4...> Subject: [LACoBirds] Concrete Chorus Recruitment
Hi LACoBIRDS community,
My name is Maya, and I’m an undergraduate student and researcher at UCLA.
I’m helping support a multi-city study focused on understanding the drivers
of urban bird biodiversity, in collaboration with researchers at Colorado
State University.
As part of this work, we are supporting a community science project called
Concrete Chorus, which engages residents in collecting short sound
recordings of birds across urban areas. Our goal is to better understand
how environmental and social factors (such as tree canopy, green space, and
neighborhood characteristics) shape bird diversity in cities, including
patterns related to inequities in access to the benefits of nature.
We are currently recruiting volunteers across Los Angeles and wanted to
reach out to see whether this opportunity might be a good fit to share
through LACoBIRDS networks, programs, or community engagement channels.
Participation is designed to be simple and accessible: volunteers visit an
assigned site near where they live or work four times in May - June and
make short, 3-minute recordings using the free Merlin Bird ID app. Just 12
minutes of data collection in total! These recordings contribute valuable
data to better understand how birds use urban landscapes and how we can
support more biodiverse and equitable cities.

Birders:
Santa Monica Bay Audubon Society invites you to
our monthly program Tuesday evening.
Building California's First Statewide Breeding
Bird Atlas, with Van Pierszalowski.
Zoom Evening Meeting, Tuesday, 7 April, 7:30 p.m.
Zoom waiting room opens 7:15 p.m.
From the ocean to the deserts to the highest
mountains, California is home to tens of millions
of birds. But there’s no one definitive resource
laying out exactly where the more than 700 bird
species that live and breed in California can be
found. The California Bird Atlas project aims to
change that, by doing the first comprehensive,
detailed bird survey of the entire state all 58
counties, all 163,000 square miles. By the end of
February over 100 breeding species had been
confirmed, and by mid-March over 50,000 trip
lists had been recorded by birders statewide. The
leader of the project, Van Pierszalowski, tells
us what’s involved in doing one of the most
ambitious bird science projects ever, and how
everyday birders can contribute to the effort.
Van Pierszalowski is the Executive Director of
the California Bird Atlas. Van’s childhood was
split between Cambria, CA, and Kodiak Island, AK,
where he worked on his father’s commercial salmon
fishing boat for eight years. After earning a
degree in Anthropology at UC Berkeley, he
embarked on a successful career as a songwriter
and musician, appearing on TV shows like Late
Night with Conan O’Brien and CBS News Sunday
Morning. Now living in LA, he’s fallen in love
with the area’s varied habitats and stunning
vagrant birds, and is continually inspired by its
diverse birding community. In 2023, Van completed
a California Big Year, recording 503 species,
becoming only the second birder to surpass 500 in
a single year in the state. He is an eBird
Regional Reviewer for Los Angeles County, and
leads trips for several local organizations,
including Los Angeles Birders and the Pasadena Audubon Society.
Date: 4/5/26 12:39 am From: Naresh Satyan via groups.io <naresh.satyan...> Subject: [LACoBirds] Early season report from the Castaic lake area
Hi all,
This morning (Saturday 4/4), Armando Martinez, Jonathan Nakai and I hiked some trails on the west side of Castaic Lake. The habitat here is rolling hills with open fields of grass and low shrubs. We had good weather for much of the hike before it got pretty windy midmorning. The big highlight was a spectacle of several thousand Painted Ladies migrating through the area, along with a few other butterfly species in smaller numbers. We also had quite a lot of bird activity. There were a few migrants and several birds on breeding territories. Particularly interesting were 17 singing male Lazuli Buntings -- I've usually only been seeing such numbers in late April here. Other expected breeding species were also well-represented, though I was surprised not to find any Costa's Hummingbirds, and it seemed like some residents like Rufous-crowned and Bell's Sparrows had gone silent (presumably on nests?). We also found no Grasshopper Sparrows (as expected).
This is the Los Angeles Rare Bird Alert for April 4, 2026.
A RED-NECKED GREBE was in the Los Angeles Harbor by Terminal Island from March 30-April 3. It was last visible from near the Japanese Fishing Memorial.

Hi Everyone, We're off to a very strong start with the California Bird Atlas across the state. In this email I want to summarize some results for Los Angeles County. First, a bit of background: Los Angeles County is divided into 434 rectangular blocks based on the US Geological Survey topographic quadrangle maps. Each quadrangle has a name, such as "Waterman Mountain," and each quadrangle is subdivided into six rectangles that are about 3 miles on a side: Northwest, Northeast, Center West, Center East, Southwest, and Southeast. That is:NW NECW CESW SE I poked around in the California Bird Atlas eBird portal (https://ebird.org/atlascalifornia/home) to see how we're doing since January 1. As of 10 am on the morning of March 28, here are some statistics for LA County: Number of Atlasers = 483Hours of Atlas effort = 4975 eBird checklists = 6817Blocks with data = 315 (73% of the county total) Number of species with breeding codes: 203Number of species with breeding confirmed: 90 Here are the species (in taxonomic order) with breeding confirmed in at least 10 blocks: Blocks 13 Mourning Dove 26 Anna's Hummingbird 35 Allen's Hummingbird 10 Great Blue Heron 11 Cooper's Hawk 13 Red-shouldered Hawk 34 Red-tailed Hawk 19 Great Horned Owl 21 Black Phoebe 11 Cassin's Kingbird 18 California Scrub-Jay 37 American Crow 69 Common Raven 12 Oak Titmouse 54 Bushtit 13 Bewick's Wren 26 European Starling 10 Northern Mockingbird 13 Western Bluebird 13 Scaly-breasted Munia 38 House Sparrow 59 House Finch 14 Dark-eyed Junco 14 Song Sparrow 19 California Towhee Common raven has been confirmed the most: in 69 blocks. Here are the blocks where at least 10 species have been confirmed: Blocks with 10+ Species Confirmed: N Location 13 Burbank SE 13 El Monte SE 19 Hollywood NE 12 Hollywood SW 12 Long Beach CE 11 Long Beach CW 15 Los Alamitos CW 12 Los Alamitos NW 11 Los Angeles CW 16 Los Angeles NW 15 Mt. Wilson SE 16 Mt. Wilson SW 16 Newhall CW 14 Ontario NW 22 Pasadena CE 19 Pasadena CW 11 Pasadena SE 18 San Dimas CE 26 San Dimas NE 23 Van Nuys CW 28 Whittier SE The number on the left gives the number of blocks. Here are the blocks with at least 50 species with a breeding code: Blocks with 50+ Species Coded: N Location 51 Baldwin Park NE 71 Burbank SE 54 Hollywood NE 57 Los Angeles NW 50 Mt. Wilson CW 50 Mt. Wilson SE 55 Mt. Wilson SW 61 Pasadena CE 54 Pasadena CW 55 Pasadena SE 67 San Dimas NE 69 San Fernando SE 57 Van Nuys CW 55 Whittier SE Given that there's been effort in 315 blocks, this means that there's no data for 119 blocks, which are concentrated in the San Gabriel Mountains, the Castaic Highlands (i.e., north of Santa Clarita), and in the Antelope Valley.

All, Highway 2 is now open between Big Pines and Vincent Gap. Blue Ridge Road has a locked gate across it, as does Grassy Hollow. There are still snow patches along the road, and Mt. Baden-Powell has quite a bit of snow. Here are my checklists for three stops along that stretch:
Date: 3/22/26 6:50 pm From: Kimball Garrett via groups.io <cyanolyca818...> Subject: [LACoBirds] Big Rock Creek notes
Birders,
The road up Big Rock Creek from the Big Pines Hwy in Valyermo has finally reopened after the December/January storms. The good news is that there is now access to the Big Rock Creek riparian (from the National Forest Boundary upstream to Sycamore Flat Campground) and to the Big Rock Creek Campground area. The bad news is that the hordes of weekend revelers who trash the creek are now back in full force, so expect a bit of chaos if you visit on weekends. However, almost nobody goes to the end of the paved road (at the Fenner Canyon Prison Camp) to bird the BIg Rock Campground area, and it is quite birdy right now. [It looks like the gate on the road up to the South Fork of BIg Rock Creek is closed and locked.]
The gate to the road to and beyond Big Rock Campground is closed and locked, so you can't drive into the campground or up to Angeles Crest Hwy. at Vincent Gap. Not that you could do that anyway since the winter storms completely obliterated the road from shortly beyond the gate to the Icy Springs tributary confluence and beyond, You can make your way on foot (being careful in several areas where what used to be the road is now a set of ravines with lots of rocks of various sizes and shapes). This morning I walked about a mile up the road and had lots of bird activity. There were at least eight singing territorial Black-throated Gray Warblers (similar to Naresh's experience yesterday on the Angeles Crest beyond Chilao). Also at least six singing Western Warbling-Vireos, a Western Flycatcher, several Townsend's Solitaires, and an active Hutton's Vireo nest. See my eBird list here: https://ebird.org/atlascalifornia/checklist/S312148398
Lawrence's Goldfinches have been common and conspicuous through most of the Valyermo/Juniper Hills/Pearblossom area in the past few weeks (with some at Big Rock as well). Scott's Orioles are just now showing up in force in the Joshua tree/juniper woodlands.
Not much movement of vultures and Swainson's Hawks yet (a couple of big vulture days a few weeks ago, but the only Swainson's I've seen in the desert foothills was a single bird yesterday in Juniper Hills that had likely roosted the previous night in the area).
