Subject: [LACoBirds] America's Birdies County Recap: 266 Species |
Hi Everyone, This is the final summary for America's Birdiest County in
Los Angeles on April 25-27, 2025. The total this year was 266 species.
After the last update we added Least Tern, Scripps's Murrelet, and
Townsend's Solitaire but subracted Tennessee Warbler and Plumbeous
Vireo, so our total increased by one relative to the last email I
posted. How does our total compare with results from previous years?
Here are America's Birdiest County totals for Los Angeles County since
2003:
Year Total
2025 266 Apr 25-27
2024 276 Apr 26-28
2023 268 Apr 28-30
2022 265 Apr 22-24
2021 277 Apr 23-25
2020 No count due to covid 19
2019 257 Apr 26-28
2018 263 Apr 27-29
2017 264 Apr 28-30
2016 270 Apr 29-May 1
2015 275 Apr 25-27
2014 272 Apr 25-27
2013 265 Apr 26-28
2012 262 Apr 29-30
2011 277 Apr 22-24
2010 271 Apr 23-25
2009 264 Apr 24-26
2008 255 Apr 25-27
2007 271 Apr 26-28
2006 263 Apr 28-30 Format changed from one day to three days; more
organization
2005 246
2004 239
2003 239 ** Average from 2003-present: 263.9 +- 11.0 Our total this
year was two species above our long-term average of 264, so in effect,
we hit the mean from previous years. Not every year can be
exceptional!
Finding this many species takes a lot of effort, and we got that many
because a lot of dedicated and knowledgeable people went into the
field and covered the most important locations for birds across the
county. This resulted in excellent coverage at the Piute Ponds,
Apollo Park, the San Gabriel Mountains, Bonelli Park, Malibu Lagoon,
parks in and near Long Beach, Bear Divide, and the Ballona Playa de
Rey area. Nevertheless, we struggled to find some rarities and
seasonal birds that
had apparently left within a few days of the count, or were somehow
missed. We also struggled with a late winter storm that caused
widespread rain on Saturday and snow in the mountains on Saturday and
Sunday. Despite this, we actually had decent coverage with multiple
teams of observers in the mountains but struck out with high-elevation
species we often find such as flammulated owl, Williamson's Sapsucker,
Clark's Nutcracker, and Golden-crowned Kinglet. We had observers in
suitable locations for most of these except for the sapsucker, which
is usually at elevations above 8000 feet in late April. None of the
observers went that high due to the winter weather and road and trail
closures. Migration was also late this year and may be the reason we
failed to find gray flycatcher, which we never missed previously.
This may also account for the fact that black-chinned sparrow was
reported only once all weekend. Normally there are at least several
reports.
It's much easier to exceed 260 species than it was only several years
ago because numerous introduced species have been added to the state
list in recent years: Nanday parakeet, yellow-chevroned parakeet,
Lilac-crowned parrot, mitred parakeet, red-masked parakeet,
red-whiskered bulbul, and scaly-breasted munia. A few years ago we
also relaxed our previous restriction on counting bald eagles
on Catalina Island due to our (incorrect) perception that they needed
human intervention to survive. Now they're also nesting annually
along highway 39 on the mainland as well. Previous America's Birdiest
County winners:

2011 277 Los Angeles
2010 271 Los Angeles
2009 264 Los Angeles
2008 255 Los Angeles
2007 271 Los Angeles
2006 263 Los Angeles
2005 250 Monterey and San Diego (tie)
2004 266 San Diego
2003 248 Monterey America's Birdiest County was a one-day event
during its first three years. Starting in 2006, the format changed to
three days. 2006 is also the first year that we really got organized
in Los Angeles County and that accounts for the distinct uptick in the
number of species relative to the first three years. We added one new
species this year:
Pigeon Guillemot How does one new species compare with results from
previous years?
Here are the number of new species that we've added since 2010:
2025 1
2024 6
2023 4 (two were introduced)
2022 3 (two were introduced)
2021 5 (two were introduced)
2020 No count due to covid 19
2019 3
2018 0 Only year we didn't add any species
2017 1
2016 5
2015 4
2014 5
2013 3
2012 5
2011 7
2010 5The one species we added in 2025 was the fewest since we didn't
add any in 2018. Our recent history of adding a few species annually
indicates that there are still new species to find in future years.
Given the near misses we have every year, it may be many years before
we run out of new ones, even without introduced species newly accepted
by the California Bird Records Committee. For example, on several
occasions in the last decade we have just missed broad-winged hawk and
that happened again this year. Cocos Booby (formerly known as Brown
Booby) seems inevitable, and there were reports from ships this year,
but none from land. We keep missing Sage Thrasher by less than two
weeks.

Painted Bunting Total: 354 species
Of the species we've found to date, we have found the same ~200 every
year, accounting for about 3/4 of our annual average.
Species Found Only Once:
We have found 33 species only once indicating that about 9% are
"one-hit wonders." Examples from previous years include Ridgeway's
rail, yellow-billed loon, field sparrow, ruff, red-throated pipit,
evening grosbeak, and red-faced warbler.
There are also numerous species that we find about 1/2 of the time,
probably a consequence of the fact that we schedule the event in late
April when wintering birds are leaving and when many spring migrants
are just arriving.
Even though some species are reported nearly every year, there are a
number that we struggle to find, and it's often through the dedicated
efforts of a few people that we find them. Typical examples include
Praire falcon, Golden-crowned kinglet, LeConte's thrasher, Clark's
nutcracker, Williamson's sapsucker, and flammulated owl. Of these,
this year we missed the kinglet, thrasher, nutcracker, sapsucker, and
owl.
Here are species we found that were particularly notable:
(Found less than or equal to five times previously and not
introduced).
05 Canvasback
05 Scripps's Murrelet
03 Cassin's Auklet
01 Pigeon Guillemot
03 California Condor.
03 Thick-billed Kingbird
04 Northern Parula
Once again, the number in the first two columns gives the number of
years when we have found this species since 2004.
As mentioned above, yellow-crowned night-heron appears to be more
regular and we've found it on the last eight counts. Given the
explosive increase in neotropic cormorant numbers, those have become
regular as well. So have vermilion flycatchers.
What were our worst misses?
Here's a list of species we missed that were found at least 11 times
previously:19 Greater White-fronted Goose
11 Hooded Merganser: Missed by a couple of weeks
15 Gambel's Quail: Nobody on San Clemente Island
15 Chukar: Nobody on San Clemente Island
11 Horned Grebe: Missed by less than one week
15 Inca Dove
15 Common Ground-Dove: No eBird reports in 2024
16 Short-billed Dowitcher
16 Solitary Sandiper: missed a couple of days
19 Lesser Yellowlegs. Arg!
19 Sooty Shearwater
18 White-tailed Kite
12 Flammulated Owl
14 Burrowing Owl: Population appears in serious decline
16 Spotted Owl: Population appears in serious decline
16 Williamson's Sapsucker
15 Lewis's Woodpecker
20 Gray Flycatcher
12 Plumbeous Vireo
17 Clark's Nutcracker
14 LeConte's ThrasherOf these, this was only the third time we've
missed White-tailed Kite. We missed it by only a few days. Our worst
miss, though, was gray flycatcher: this is the only year we haven't
found one.
We've had considerable success with Burrowing Owl and Spotted Owl in
the past, but both are in decline, and we missed them again this year.
This is the seventh year in a row that we have failed to find
burrowing owl despitel dedicated searches. Here's a list of species
reported within one week of the count that we missed:
Most were extracted from eBird:Near-Misses: +- one week (on land)
Greater White-fronted Goose
Short-billed Dowitcher: missed by 1 day
Solitary Sandpiper
Lesser Yellowlegs: 3 days
Red Knot
Iceland Gull
Horned Grebe
White-Tailed Kite
Broad-winged Hawk
Burrowing Owl
Lewis's Woodpecker
Gray Flycatcher
Golden-crowned Kinglet
Clark's Nutcracker
Clay-colored Sparrow: missed by one day.
Lucy's Warbler
Following our longstanding protocol, we don't count species seen from
boats, but this year there were quite a few that were notable. Here's
a list of species seen during ABC weekend and +- one week:
Pomarine Jaeger
Rhinoceros Auklet
Sabine's Gull
Common Tern
Laysan Albatross
Black-footed Albatross
Black Storm-petrel
Sooty Shearwater
Black-vented Shearwater
Cocos Booby (formerly known as Brown Booby)
Murphy's Petrel
Cook's Petrel
Some were found during a Sea and Sage trip and most of the others were
found during repositioning cruises. Whether all will be accepted as
valid eBird records is another matter, though.
Given the number of new species that we find each year, which species
might be next? We've missed broad-winged hawk by less than one week
on multiple occasions, so we should find it eventually. Cocos Boobies
are increasing in abundance and are sometimes reported fairly often,
so we should sweep one up. I'm surprised that we haven't found reddish
egret yet. Despite these predictions, the rarities we find suggests
something not mentioned above is likely to turn up. That happened
again this year!
It seems inevitable that more exotics will be added to the state list
by the California Bird Records Committee and thus become countable.
Species that might be added in the not-too-distant future include
Egyptian goose, Swinhoe's White-eye, and perhaps Pin-tailed Whydah.
We have started to keep track of uncountable, non-native species that
we find, but we didn't attempt to organize dedicated searches.
Here are the ones that were reported, in no particular order:Exotics
Found:
Egyptian Goose
Domestic geese
Domestic mallard
Muscovy Duck
Indian Peafowl
Rose-ringed Parakeet
Yellow-headed Amazon
Pin-tailed Whydah
Swinhoe's White-eye
Northern Cardinal
How many more species could we find during this count?
We've already found 277 species twice, and 276 and 275 species once,
so 280 species is probably within reach if we have really good luck.
285 species might be attainable...particularly if the CBRC continues
to add introduced species to the state list. Finding more than that
is probably very unlikely even if we dramatically increase our
organization and level of effort because we're already up against the
limit of the number of birds regularly in the area at this time of
year.
The significance of "America's Birdiest County" has grown considerably
since we started in 2003. It's become much more than a friendly
competition with other counties and has turned into a educational
event that continues to improve our body of knowledge of the status
and distribution of birds in our area. Knowledge of where birds are
has grown to the point that we usually find most species that are very
local. Although there are other events during the year such as
Christmas Bird Counts and the Great Backyard Bird Count, there aren't
many events in the spring when migration is in full swing. As such,
we've been obtaining a detailed sample for 20 years at a time of year
when few other surveys occur. Now, however, the Bear Divide Migration
Count, has become a regular event, is providing another means for
assessing species in this area in a systematic way. There are also
suggestions from Richard Crossley's observations in Gorman that
regular surveys there could also yield very important results. As
mentioned above, ABC weekend is also documenting changes, both
positive and negative, in the avifauna in our area for species such as
vermilion flycatcher, neotropic cormorant, yellow-crowned night heron,
zone-tailed hawk, tricolored blackbird, white-tailed kite, American
dipper, and burrowing owl. ** Use of the Merlin App **
The Merlin bird ID app has become extremely popular recently and is
being used extensively. Unfortunately, it doesn't always identify
sounds correctly, and some species are being entered into eBird
primarily based on results from the Merlin app without confirmation by
the observer. This lead to some incorrectly identified species during
ABC weekend this year. PLEASE do NOT rely solely on Merlin to
identify species! Although Merlin is very capable and getting better,
it makes mistakes. If you think you found something interesting based
on a Merlin recording, please include the recording in your eBird list
and try to see the bird and photograph it.
Most of our participants use eBird to archive their observations and
many people are uploading photos and audio recordings, which makes the
reports considerably more valuable. Every year during ABC weekend
there's a significant increase in the number of records entered into
eBird. We scour eBird for reports that weren't submitted to us or
posted on listserves. This often adds 2-4 species after the count
that we would otherwise miss. Many species were reported directly to
me but I also found several dozen by checking eBird.
Use of eBird is making an increasingingly important contribution to
ornithology worldwide. eBird data is appearing in a
rapidly-increasing number of peer-reviewed publications in prominent
scientific journals and it's having a pronounced impact on many areas
of bird conservation. Articles that discuss results from eBird have
appeared hundreds of times in some of the highest-impact peer-reviewed
scientific journals, and eBird is widely considered to be among the
most important community science projects in existence. As a very
recent example, the May 1 issue of the journal Science published a
paper by Alison Johnston et al. entitled "North American bird declines
are greatest where species are most abundant" that tracked population
changes in 495 species using data submitted to eBird. Here's a link to
the abstract:

Science paper requires a subscription; you can also view a summary on
the eBird website at:

Your eBird contributions really do make a difference! Thank you again
to everyone who contributed to America's Birdiest County this year!
Best wishes, Lance Lance Benner
