Subject: [LACoBirds] Solitary Sandpipers and Western Cattle Egret San Gab Coastal Basin Spreading Grounds
Hello birders,
This morning, 13 September, there was a Western Cattle Egret in the San Gabriel River between Whittier Blvd and Dunlop Crossing. The riverbed is best viewed from the settling basins on the west side. The west side is higher so the view is better. In the very small basin adjacent to Washington Blvd on the extreme south end, there were three Solitary Sandpipers. The large south basin is still full and some water is spilling into this very small basin and creating some shorebird habitat. Lots of migrants in the area between Whittier and Washington Blvds. The riverbed, just upstream of Washington must have a lot of fish. It's a good place to watch Osprey diving for fish, including carp, tilapia and catfish.
There is an island in the south basin that is dominated by a Mulberry Tree that hosts numerous Neotropic Cormorants and at least three Neotropic Cormorant nests.  Many fishing Neotropic Cormorants in the adjacent riverbed.
Happy birding.
Larry SchmahlWhittier

Subject: [LACoBirds] Red-footed Booby and the apparent demise of the LACoBirds listserve
Birders,

I realize that posting rarities to this listserv is viewed as something as
archaic as using smoke signals or a telegraph to some, but many people
still use it and I don't know why we can't follow the lead of counties like
San Diego where there are daily reports of unusual birds and other
interesting sightings on their listserv. Yes, rabid listers and most
younger birders prefer other channels of communication, which is fine, but
can somebody using those channels also take a second to post information on
the LACoBirds listserv as well?

Sure, eBird alerts or WhatsApp/Discord/etc. channels probably alerted most
birders to the presence of a Red-footed Booby found early in this morning
at Malibu Lagoon and present later in the morning a ways east along PCH
(near the mouth of Tuna Canyon), but in the interest of wider communication
and discussion it would have been nice to have the sighting posted here.

The developing fall irruptions of species like Pinyon Jays, Clark's
Nutcrackers, and Red-breasted Nuthatches have been noted on some southern
California listservs in recent days (thanks Lance for posting your Pinyon
Jay near Buckhorn). Tracking those sorts of events would be an ideal use of
this listserv in addition to getting the word out about rarities.

Subject: [LACoBirds] Storm-petrels south of Catalina island
Hi all,

A quick report from a fantastic small-boat pelagic trip today aboard the
zodiac Skimmer out of Newport Beach with Captain Delaney T and 5 birders on
board. With stronger winds predicted outside San Clemente island, we chose
to instead go to the south end of Catalina island, then head south from
there to the 43 Bank (/Forty mile bank) and back via the Thirty mile bank.

The highlight of the trip was a huge number and diversity of storm-petrels.
There was what appeared to be a dead large mammal on the ocean floor at the
277 Bank (southeast of Catalina Island) which hosted several thousand
storm-petrels, and we also found another aggregation of several hundred
birds close to the top of the Thirty mile bank (on the west side of the
ridge).

- Black Storm-Petrels: estimated between 3000 and 4000 birds for the
day, everywhere along the route but mostly in these huge flocks
- Least Storm-Petrels: 500-600 birds, mostly mixed in with the large
Black Storm-Petrel rafts, but also singles all along the route including
several in fairly nearshore Orange County waters
- WILSON'S STORM-PETRELS: At least three different individuals (two
birds over the 277 bank and one near the 30 mile bank), all associating
with the large Black and Least Storm-Petrel rafts
- WEDGE-RUMPED STORM-PETREL: A stunning bird at the 30 mile bank, also
with the Black and Least Storm-Petrel flock.
- Townsend's Storm-Petrels: ~10 birds identified as this species, among
many Leach's/Townsend's type birds; all white-rumped; singles and not
associating with the large rafts; mostly between Catalina island and Lasuen
sea mount, and dropping off in numbers further south
- Leach's Storm-Petrels: ~20 birds, almost all dark-rumped; singles and
not associating with the large rafts.

We had fantastic views of most of these species, and also got to record
vocalizations of Black Storm-Petrels squabbling over food, which I don't
remember hearing at sea before.

Otherwise, we had 5 Cocos Boobies, a few Common Terns, a pair of Craveri's
Murrelets, a fly-by Guadalupe Murrelet (above eye level!), a Fulmar, a few
phalaropes of both types, and not too many shearwaters or jaegers.

It may take some while to get eBird checklists done, but there should be
photos eventually, and the Wedge-rumped Storm-Petrel claim will need to be
reviewed by the CBRC. Storm-petrels are not easy, and some corrections to
these numbers are possible (even expected).

Regards,
Naresh (w/ Chris Dean, Mark Scheel, Mark Wilson, Ashley Hopkins)

N = 79 blocks with at least 50 species coded.

(The columns above were aligned when I wrote the email, but no
guarantees they'll appear aligned in your email!)

In the table above, the left column gives the number of species for
which breeding has been confirmed, the 2nd column gives the number
coded, the third column gives the percentage of species where breeding
has been confirmed, the fourth column gives the number of species
expected (from the atlas in the 1990s), and then on the far right is
the name of the block. If an upper case "C" appears then the block
would be considered complete by criteria adopted for the first LA
County atlas.

For many blocks above, we have already coded more species than were
estimated to be present during the atlas in the 1990s. For other
blocks, though, there are still a lot more species we could find that
haven't been reported yet.

Completeness criteria adopted, from the first atlas in the 1990s:

At least 90% of expected species coded, at least 50% of them
confirmed, and the total number coded is at least as many as estimated
for the first atlas.

If we consider only blocks with 50+ species coded, then 32 (7.3%) of
the blocks are complete.

But if we include blocks with at least 40 species coded (not shown
above to save space), then the number of complete blocks increases to
34, so at least 34/434 = 7.8% of blocks in the county are complete.

That's pretty good for the first year of an atlas, given that most of
us hadn't particpated in a bird atlas previously, and that we've been
learning how to do this as we go.

Given that many of us are now experienced and that we've made good
progress in many blocks, it's likely that the number of complete
blocks will jump significantly next year.

What are the protocols for completing a block in the CURRENT atlas?

That will be announced by early next year, but it's likely to involve
the number of species coded for each block and the percentage relative
to the number of species expected. We're monitoring those statistics
using the Blockboard progress tracker tool, which is available online
at:

https://blockboard.californiabirdatlas.org

"Blockboard" uses estimates of the number of species that could be
present in each block based on previous eBird reports; this
distribution model is provided by eBird central.

As a result, it's really important that you include breeding codes in
your checklists whenever possible because they are crucial for
monitoring our progress. I mention this because A LOT of species
reported in eBird in the atlas portal in Los Angeles County DO
NOT have breeding codes: many observers simply didn't report them,
particularly for lower levels of breeding evidence such as "H-in
suitable habitat" and "S-singing bird", and as a result, the
numbers in the eBird portal and in the Blockboard tool underestimate
the actual numbers of species in most of the blocks. In blocks where
40+ species have been reported, the underestimate is often at the
10-20% level; in blocks with only a little coverage, often only 1/2 to
1/4 of the species have received breeding codes. PLEASE USE BREEDING
CODES!

What about blocks in LA County with zero coverage?

Blocks with zero data are concentrated in the Antelope Valley, remote
regions of the San Gabriel Mountains, remote regions of the mountains
north of Santa Clarita, and on Santa Catalina and San Clemente
Islands.

The blocks in the Antelope Valley and along the north slope of the
mountains are accessible by car but there are at least 10 blocks in
the mountains that are accessible only on trails or on dirt roads that
are either behind locked gates or too rough for even 4WD vehicles.

To view our coverage with individual blocks you can check the
Blockboard tool above or go to a somewhat different (and less
complicated) map on the eBird website:

https://ebird.org/atlascalifornia/effortmap

and then zoom in on Los Angeles County. The default setting for this
map shows "Diurnal effort hours," but you can toggle it to other
settings, such as "Coded species" or "Confirmed species" that are
arguably more useful.

Meanwhile, observers are still confirming breeding for species across
Los Angeles County even though we're into early September, so please
continue to use the atlas eBird portal and report all levels of
breeding evidence in your eBird lists.

Also, several of you are working behind the scenes to arrange access
to areas that are normally off-limits to the public. Thank you very
much for your help with this! If you're one of those people but you
haven't reached out to us yet to let us know, please send an email so
we can keep track and avoid duplicating effort. We really appreciate
your help!

Once again, if you haven't already contributed to the atlas, please
join us! Even checklists in your yard and neighborhood are useful
(often they're VERY useful).

Joining is easy: on a computer, go to

https://ebird.org/atlascalifornia/home

and then click on the rectangle stating "Join Project" on the lower
left. When you enter birds in eBird, be sure to drop down the menu for
breeding codes and select the ones that are appropriate for behavior
you observe.

From a smartphone using the eBird mobile app, select "Choose Projects"
on the home screen and then select the California Bird Atlas. If you
don't see "Choose Projects" then you may need to update to the latest
version of the app.

Thank you again for your all your help with the atlas!

Regards,

Lance

Subject: [LACoBirds] Nazca Booby off LA harbor
Hi all,

There is a near-adult Nazca Booby on the #2 buoy just off Angels Gate. No
need to argue about species ID. Our captain tells us it has been hanging
out on this buoy for 2 weeks now, so it seems to be consistent.

Coords: 33°40'26.8"N 118°13'40.9"W

You can charter a boat to go out and see it. One option is
socalwhalewatching.com -- easily within range of a 2 hour charter, and they
know where the bird is. You can also take your chances on a big whale
watching boat, but they seem less and less keen on stopping for birds these
days (this is the same buoy that hosted a couple of boobies many years ago

Subject: [LACoBirds] Birds at the San Gabriel spreading grounds
Hi all,

This afternoon (9/5), I stopped by the San Gabriel spreading basins hoping
to look at some gulls, but the birding overall was very good and I thought
it was worth posting a report to the listserv.

Understanding the status of water and vegetation levels at the spreading
basins and the adjacent San Gabriel river is beyond my capabilities.
Conditions change from day to day depending on weather and the whims of LA
Public Works. But it is now excellent.

The large spreading basin south of Mines is full, and water is just
beginning to flow from this basin to the southernmost basin.
- This basin had 1000 Western Gulls today, including at least 200
juveniles. It is a great place to study juvenile Western Gulls. I looked
fairly carefully through the flock and the only other gulls I found were 9
California Gulls. Interestingly, 7 of the 9 birds were juveniles that all
looked different from each other (including one bird that Merlin was
adamant was a Western Gull when I was uploading photos to eBird).
- The other highlight in this basin is a lone (mulberry?) tree that now
hosts a large nesting colony of Neotropic Cormorants. The birds were
displaying, aggressively chasing each other, courting and copulating with
grunting vocalizations, building nests, and at least two nests seemed to
have birds in incubating postures. I counted 38 Neotropic Cormorants in the
tree (+ another 10 cormorants that were likely Neotropics but I couldn't
see well), and 12 birds elsewhere in the basin and the adjacent river. I'm
reporting the total as 44 birds, though I think the actual number of
Neotropic Cormorants in the area exceeded 50-60 birds. This is an
incredible increase in numbers of this species in LA county. Perhaps people
can get a more accurate count over the next few days.

The basin immediately north of Mines was dry, but there was a tiny puddle
at the north end of this basin that hosted 3 Killdeer, 1 Western Sandpiper,
4 Least Sandpipers and 2 Solitary Sandpipers.

The river looks excellent, with miles of weedy habitat that should have
seedeaters (but impossible to see), shallow water, mudflats, and shallow
shrinking pools that concentrate fish and attract fish-eating birds. These
included about 100 each of Snowy and Great Egrets in the river and 3
Ospreys hunting while calling. The most interesting shorebird on the river
was a juvenile Short-billed Dowitcher.

eBird list: https://ebird.org/atlascalifornia/checklist/S390161673

If you made it this far and are interested in birding along a stretch of
the San Gabriel river on Sunday Sep 27 as part of a survey of birds on the
river this fall, please email me off-list :). The birding away from the
spreading basins is usually not as glamorous, but always interesting.

Regards,
Naresh

Dave Moody loose in Redondo Beach with a view of the ocean and he had a
booby that he saw with his bare eyes yes, he is that good but he didn’t
describe plum or color pattern, yet. He is working his way to the harbor in
Redondo Beach to look for the Nazca Booby, although that could be the one
that he saw following the fishing boat. These are fishing boats full of
fisherman who pay to ride for a few hours, not commercial large fishing

Subject: [LACoBirds] Northern Waterthrush along Little Rock Creek
Birders,

A Northern Waterthrush was foraging along the edge of Little Rock Creek
north of Mt. Emma Rd.this morning (30 August). See eBird list here:
https://ebird.org/atlascalifornia/checklist/S388374899

This is NOT the upper stretch of Little Rock Creek near the Little Rock
Reservoir Dam (where many of you saw the Brown-crested Flycatchers a few
weeks ago). Rather, it is downstream (north) of Mt. Emma Rd. Unless you
have a monster truck and enjoy destroying streambottom habitat you will
need to park a short ways below Mt. Emma Rd, and walk down the dry cobble
streambed until you reach the obvious riparian forest. Take the dirt road
on the east side of the creek bottom about 250 yards and park. [Be VERY
careful when turning into and out of this dirt road from/to Mt. Emma Rd. as
the latter is a favorite of crazy redneck speedsters.] After parking it is
another 0.3 mi. to reach the main riparian zone.

The waterthrush was about halfway down the riparian zone where there is a
concrete check dam -- it was along the creek in the first 50 feet or so
above the dam. Coordinates for this spot are: 34 30' 43.42" N -118 01'
05.52"W
Not too many other migrants there this morning, but it's always an
interesting spot.

Subject: [LACoBirds] 2026 LA River Fall shorebird survey: Day 2 results
Hi all,

Today was the second of three surveys of shorebirds in the Los Angeles
river planned for this fall. The goal of the surveys is to get a fairly
thorough picture of shorebirds using the various stretches of the river,
and how their distribution is changing over time. We've been doing three
surveys per year each fall since 2023.

We had mostly the same team as previous surveys: Jeff Boyd (Golden Shore to
Willow), Jon Fisher and Sarah Ngo (Willow to Wardlow), Lance Benner
(Wardlow to Rosecrans, by bike), Mark and Janet Scheel (Southern to
Atlantic), Andy Birch (110/5 intersection to Burbank confluence), Naresh
Satyan (Burbank, Sepulveda basin). We covered all stretches of the river
that have shorebirds (and in my case, also checked stretches that did not
have any shorebirds).

It was a warm/hot day along the river, with temperatures starting around 73
F and warming to about 90 F inland. We had clear skies and practically no
wind all morning. The tide was rising +0.1 to +4.9 ft at the river mouth in
Long Beach. Water levels in the river were fairly high throughout the
survey area,
with strong flow in the central channel, and limited shorebird habitat in
the upstream areas.

Shorebird numbers and diversity were pretty good on the southern/downstream
part of the river in Long Beach. We tallied more species and higher numbers
than all our previous surveys on this date. On the other hand, it was
fairly quiet on the upper reaches, particularly in the Vernon-South Gate
stretch where we "missed" several hundred Least Sandpipers compared to
previous years.

- Western Sandpipers are now present in pretty decent numbers in Long
Beach. Our total for today was 1812 birds. In 2023, '24 and '25, we had
400, 193 and 132 birds respectively. This was a welcome change!
- We are in about the peak window for juvenile Short-billed Dowitchers, and
the 59 birds counted today was more than double the previous high count in
the past 4 years. (There are juvenile Short-billed Dowitchers everywhere
now -- I also had good numbers along Ballona creek later today).
- 74 Semipalmated Plovers was also a high count, including 45 birds at
Willow St.
- Our tally of 1091 Least Sandpipers was a little less than the recent
average.
- Less common birds included a Semipalmated Sandpiper, a Solitary Sandpiper
and a couple of Baird's Sandpipers -- all at Willow St.

The results of today's survey are on eBird here:
https://ebird.org/tripreport/565419
The results of the first day's survey on August 1, 2026 are here:
https://ebird.org/tripreport/554972

For comparison, the results of last year's survey on August 30, 2025:
https://ebird.org/tripreport/406934

Thanks again to all the birders who counted today. The final survey for
this fall is scheduled for September 19.

Regards,
Naresh

This is the Los Angeles RBA for August 16, 2026.

A GREATER ROADRUNNER continued by the horse stables along the Los Angeles River in Long Beach through August 14. It has been seen occasionally on the east side of the river above Willow Street.

A SEMIPALMATED SANDPIPER was along the lower Los Angeles River above Willow Street in Long Beach from August 11.

Two SEMIPALMATED SANDPIPERS were at Piute Ponds on Edwards AFB (letter of permission required for access) on August 10.

Up to six BROWN-CRESTED FLYCATCHERS (including locally fledged juveniles) continued below the Little Rock-Palmdale Dam through August 14. One viewing location is at Google maps 34.4886,-118.0250. There is no vehicle access and you will need to walk the road from the locked gate to this location. Be aware of the adjacent restricted access and construction areas. Avoid entering the riparian habitat and the area near the dam itself.

Up to four SUMMER TANAGERS were at the above location through August 14 and a LUCY’S WARBLER was present on August 14.

A PURPLE MARTIN made a brief appearance along the Los Angeles River at Willow Street in Long Beach on August 16.

A SUMMER TANAGER was at Monrovia Canyon Park through August 9 around the Nature Center parking lot.

Two more SUMMER TANAGERS were at Jalapa Park in Covina on August 10.
