Hi Folks! Time for another update on the California Bird Atlas!
I continue to be impressed with the dedication of our Atlas Volunteers. We currently stand at over 8500 submitted checklists for the county in just the first 8 months of the Atlas! Way to go!! Collectively, we’ve confirmed breeding for 129 species! An excellent result for our first spring & summer.
Breeding activity for many species is slowing down, as we approach autumn… BUT IT’S NEVER GONE!! There are zero months in our county when no birds are engaged in breeding activity! Just in the past week, I’ve personally seen FIVE different species with eggs in their nests! Keep your eyes peeled for the coastal species like gulls, cormorants and guillemots to get frustrated with nest failures and start over at a late date.
(And the California Towhees have placed their latest nest inside a patch of poison oak, so I haven’t been able to get a visual on that one — the earlier-season nest on the grapevine was a lot easier to peek into!)
So, don’t hold back on reporting those well-documented confirmed codes for all sorts of species. The weather this year was just right to produce an extended production of food sources, particularly insect life. We may get some real outliers in this year’s data set!
Speaking of outliers, I was truly surprised to see confirmation of both Western and Clark’s Grebes sitting on eggs at Lopez Lake, this late in the year. Apparently, a few of them do this every year, but the numbers seem high in the current moment. Here’s a few photos, taken by Chris Hogue and myself:
Hope to see more of you out in the field! Bird On!

Ridgway's Rail (Rallus obsoletus) (1)
- Reported Aug 21, 2026 07:07 by Kilian Hampl
- Laguna Lake — Prefumo Creek Mouth, San Luis Obispo, California
- Map: http://maps.google.com/?ie=UTF8&t=p&z=13&<q...>,-120.6930037&<ll...>,-120.6930037 - Checklist: https://ebird.org/checklist/S385603506 - Comments: "***Very rare. Continuing crazy awesome find by Herb, the first in SLO county since 1973/first in 53 years! Unfortunately h/o. I first heard this bird give a single “churr” call at about 7:15 this morning shortly after arriving (though it didn’t initially register to me that that was the bird). I then heard it give several more “churr” calls and then later a partial series of clacking calls around 9 am from here: (35.264408, -120.692692), but I don’t believe it was heard after that. I was able to hear this bird well and clearly despite each encounter essentially being limited to a single call - though as previously mentioned I didn’t realize that I had heard it initially.
Similar to Black Rail, Ridgway’s Rail historically occurred in Morro Bay, but declined drastically due to habitat loss and fragmentation, etc and was eventually extirpated from SLO county in the mid-late 20th century. My understanding is that it is not well known whether nominate obsoletus (SF/Bay area) or R. o. levipes (SoCal/Light-footed) occurred here. I will take another look at Herb’s photos for a possible subspecies ID and will update if needed.
I have seen and heard many RIRAs in the Bay Area, but this is a bird I never expected to get in SLO county!
Common Gallinule (Gallinula galeata) (1) CONFIRMED

Continuing young bird found by Jay Carroll on Wednesday (8/19). This was a relatively small gallinule that had an elongated dusky reddish bill with a large dull yellow tip, a rounded dusky reddish frontal shield, dark eye, browner cheek and paler throat (signs of immaturity), and dark ashy-colored neck, breast, and belly the latter of which had pale fringing. The legs were a dull yellow and the back and some wing coverts were a deep chestnut brown. The primaries were dark. I did not hear this bird vocalize to the best of my knowledge. It was in view on and off throughout the morning and was relatively close, and my views were relatively close. A few bad photos tba eventually."
Pacific Golden-Plover (Pluvialis fulva) (1) CONFIRMED
- Reported Aug 21, 2026 07:07 by Kilian Hampl
- Laguna Lake — Prefumo Creek Mouth, San Luis Obispo, California
- Map: http://maps.google.com/?ie=UTF8&t=p&z=13&<q...>,-120.6930037&<ll...>,-120.6930037 - Checklist: https://ebird.org/checklist/S385603506 - Media: 1 Audio
- Comments: "***First truly inland county record? I can’t find any others away from the immediate coast…Regardless, Herb, Brian, and I were scanning the mudflats when I/we heard what sounded to my ear like a Golden-Plover calling. Suddenly the bird materialized flying in and it landed on the mudflats amongst the Killdeer, and it was immediately apparent that the bird I/we heard calling was, in fact, a Golden. We continued to watch this Plover as it foraged amongst the Killdeer for about twenty minutes before a Bald Eagle flew by and flushed most birds from the area. When this happened the Plover flushed as well and circled around calling, before eventually flying off in the direction of the Laguna Lake Park not to return. As mentioned previously this was an obvious Pluvialis Plover with a rather slim and more lanky build, a medium-sized dark bill, a dark eye, a buffy face, a pale supercillium that extended down around the auriculars and sides of the neck to at least the sides of the breast, a gold-spangled cap and back, a mottled dark breast and mottled dark underparts extending to the vent, pale whitish undertail coverts, and relatively short primary projection (compared to American). Due to the distance I was unable to see how many primaries projected past the tertials in the folded wing. In flight I was able to see that the tail was extensively barred and that the underwing was entirely pale, lacking the “dark armpits” of Black-bellied. The legs and toes were dark. Much of the wing coverts were old and worn, and this bird appeared to be an adult or at least a SY bird (So I guess AHY is most accurate) in prebasic molt. As mentioned previously this bird was rather vocal, giving fairly typical-sounding “chu-EET” flight calls. My views of this bird, although not exceptionally close, were decent, and I was able to see most if not all parts of this bird well. I also was able to obtain a few distant low-quality photos and recordings which will be added."

Presumably continuing birds that have been here for some time now. Initially I saw a male fly distantly over the bulrushes before landing down in them. Shortly thereafter I heard that bird vocalize and then another bird answer from elsewhere. Later just prior to my departure a female flew back into the island of bulrushes from closer to us and was in view for about a minute before moving back into the bulrushes and out of sight. I am not sure whether or not the female is the same bird that answered the male earlier in the morning, as I was not able to tell where that individual was calling from. Both birds were small buffy bitterns with buffy-streaked breasts, pale throats, white mantle lines, large buffy wing covert patches that contrasted with the darker primaries and secondaries, dark caps and short dark tails, and thick elongated yellow bills and feet, the latter of which projected past the short tail in flight. The back of the male was very dark whereas the female’s back was also darker but not quite as dark as the male’s…more brown. I could see only the pale eyes of the female, as the male was too distant to see finer details like that. I was able to see the female well, albeit briefly, whereas the male was seen more distantly and briefly and not as well. As mentioned previously I heard these birds vocalize, giving loud harsh piercing “ga-ak-gak-gak-gak!” contact calls typical of this species. I did not make any attempt to record these birds (I would have surely been unsuccessful), nor did I opt to take any photos (particularly of the female) as these birds have already been well documented here and there were several other observers present."

Please pardon this query if it's inappropriate. I'm looking for a set of three photos of the Black Tern that is currently being seen at Cayucos pier. One photo shows the bird from above with full wingspread; One shows the bird with a small fish in its beak; and the third is a front on view of the bird in flight.
I have checked all of the photos posted here. If someone took these photos and is willing to share (I will not publish them anywhere without credit) please email me. Thank you!

- Comments: "Distant Tringa duo foraging in Basin #2 from the southeast fence line. These birds appeared slimmer and slightly smaller than the more stout Killdeer nearby. Although the distance made it difficult to assess all field marks, greenish legs, a dark carpal patch, dark wing line contrasting with all white underparts, dark tail, and buffy head and breast were noted, along with a medium-length, straight bill. A third unidentified bird was nearby and appeared approximately the same size and shape as the Solitary Sandpipers, but vegetation emerging along the water’s edge prevented clear views. Poor heavily cropped photos included."

- Comments: "I assume this is the continuing bird that was first observed at this location by Kathi Marston on aug 17. I saw a small tern fly in from the west after I had been on the pier for a good 20 minutes. it seemed to have a more buoyant flight pattern and was fairly distinctive as it flew in amongst the other birds. It did seem to target pelicans and gulls as they nabbed fish, apparently hoping to get some leftovers. The back was covered in brownish gray feathers that gave it a mottled appearance. The underside was mostly white with a clean white belly and undertail coverts. Small forked tail. All black bill that was fairly straight. black legs and feet. Top of the head was dark brownish black. Two little spurs came down from the shoulder onto the upper breast."

Black Tern (Chlidonias niger) (1) CONFIRMED
- Reported Aug 17, 2026 17:20 by Pair of Wing-Nuts
- Cayucos Pier, San Luis Obispo, California

- Comments: "Continuing bird (Kathi Marston, 8/17/26) was observed foraging on both sides of the pier. This small tern was dwarfed even by the Forster’s Terns as it bounced in the wind with a buoyant flight style and rapid wingbeats. Despite remaining in flight for extended periods, the bird made only several feeding attempts.
At a distance, the bird appeared predominantly gray above, due in large part to its grayish-black upperwings, back, and dark crown. The underparts were white, except for two dark spurs on the sides of the neck that contrasted with a complete white neck collar. The bill was straight, black, and sharply pointed. The underwings were gray, as were the outer feathers of the slightly forked tail."

Date: 8/19/26 12:55 pm From: William M Killian via groups.io <wkillian6163...> Subject: [slocobirding] The hooded orioles are tanking up for the flight south
The hooded orioles are gorging themselves at the jelly tray as summer winds down. Frequently, five females jostle for position on the tray. Since May, they have devoured at least 10 lbs. of grape jelly. Easily.
We're expecting them to head south soon. The ones in our neighborhood will be well-fueled for the trip. Looking forward to seeing them again next year (our 27th hosting them).
Date: 8/19/26 9:08 am From: Rubba Johanna via groups.io <jer72701...> Subject: [slocobirding] Atascadero Lake 8/17/26
Another quiet morning at the lake. Virtually nothing on the lake other than Pied-billed Grebes.
Birds seen:
Black-crowned Night Heron
Brewer's Blackbird
White-breasted Nuthatch
Great Egret
Great Blue Heron
Belted Kingfisher
Common Yellowthroat in molt
I'd be interested in some help with the Yellowthroat ID. I didn't see the whole bird. I saw a uniformly yellow throat, breast, and belly, an olive green cap, and small, irregular black patches on the side of the neck. Looked similar to images on Google.

Notably agile in flight exhibiting rapid wing movements but didn't directly plunge into the ocean as other terns - during my stay. Its feeding behavior was interesting, as it often tried to take food from cormorants floating on the water.

Hi Sue, I too have regular Hooded Orioles at my feeders. Any day now I very much hope to see them joined by a few juveniles, which look similar to a female, and often having smaller, pinkish bills and shorter tails if I recall correctly.

Allen's Hummingbird (Selasphorus sasin) (1)
- Reported Aug 10, 2026 07:10 by Kathleen Kent
- Oakview Village, San Luis Obispo, California
- Map: http://maps.google.com/?ie=UTF8&t=p&z=13&<q...>,-120.660672&<ll...>,-120.660672 - Checklist: https://ebird.org/checklist/S382686276 - Comments: "I am submitting several photos of this bird. They are probably not conclusive as to the ID, as the details on the tail feathers are not clear enough and the photos are not very sharp. I am calling it an Allen’s hummingbird based on the fact that my Merlin app was picking up the vocalization of an Allen’s at the same time as I was photographing the bird."

Continuing bird found by Herb this morning. This bird was seen initially resting on the edge of the Tern flock, and I was able to note the large size of this bird compared to the terns, squat and lengthy structure, overall black and white plumage, bright-colored legs, dark eye, and massive thick and laterally-compressed dark bill with the basal third being brighter reddish orange and the lower mandible being longer than the upper mandible. Very soon after arriving and seeing this bird the tern flock flushed and this bird with it where I was able to see the pale underwings, dark rump and central rectricies, paler outer rectricies, and bounding emphatic nighthawk-like flight style of this species. After being flushed this bird was last seen flying off to the north towards Pismo. My views were decent but altogether brief, and I did not attempt (nor would I have had the chance) to photograph this bird…Herb should have photos."

Though they summer in my neighborhood near palms, I never see more than 2-3 at once feeding on plant nectar or berries in my yard. Today a 1 pm, when most birds are resting, 5 female Hooded Orioles all at once hit my hanging bird bath under the Prunus hedge. They Quickly bathed, and hit the top branches where remaining fruits are. Could they be rallying to fly south...? Have not seen a male for over a week, when another several frantically combed through the garden for insects, and were gone the next morning.

- Map: http://maps.google.com/?ie=UTF8&t=p&z=13&<q...>,-120.6265268&<ll...>,-120.6265268 - Checklist: https://ebird.org/checklist/S382020196 - Comments: "**Very much expected, but high. New personal high count for SLO! Very careful e/c by 1s, essentially all in different parts of the campground, most looking slightly different, and not ranging widely so I am confident that the count of 9 is accurate. I assume at least several if not most are continuing birds that I observed here last Monday (8/3). There was one at the Native Garden (35.108938, -120.627754), one by the amphitheater (35.109778, -120.628453), two on the maintenance road (35.111054, -120.626989, 35.112014, -120.626898), and 5 on the Norswing drive trail (1 north (35.110775, -120.625329), and 4 south (35.108921, -120.625546, 35.108329, -120.625011, 35.107304, -120.624995) of the trail entrance).
All birds were relatively straightforward, being large, very dull Orange-crowneds that were overall a dull olive color, with a large thick-based bill, dark eye, greener upper and slightly paler lower eye arcs, a large head with a faint veiled/hooded appearance, a streaked breast almost appearing vested, dull legs and feet, a relatively slim build and medium-length tail, and strongly and extensively streaked undertail coverts. Several birds also gave harsh metallic chip calls typical of this subspecies, though I was unsuccessful in my attempts to record all calling individuals. I was able to see all birds well and at reasonably close range, varying from the midstory at eye level to up higher in the canopy. The lighting was dismal, but I was nevertheless able to photograph at least five of the nine individuals present. This subspecies departs the Channel Islands for the mainland as early as the later half of July and usually are the first migrant/dispersing OCWAs I see in south county in early fall.
Pics tba at some point…"

I do a lot of my photo processing on my phone using Google photos. It has the obvious AI generative tools to be avoided, but there are some functions such as unblur that appear to make substantial changes and should probably not be used for photos destined for eBird.
I know I'm tempted to post the prettiest photo I can come up with, but I have to remember, its for science!
Here is a photo where I used unblur and you can see its a little goofy.

Subject: Re: [CALBIRDS] artificial intelligence and photos of birds
A lot of bird photographers utilize denoise software to sharpen edges and especially eyes. I asked ChatGPT the following:
There is a lot of negative feedback regarding the use of generative AI in bird photos that are submitted to citizen science databases such as eBird and iNaturalist. There are concerns that the use of generative AI may mask or change important identification characteristics of a species of concern and lead to improper identification. Is the use of an application such as Topaz deNoise considered generative?
IT ANSWERED:
This is an excellent question, and one that is being actively debated among birders, photographers, and citizen science organizations.
The short answer is:
Topaz DeNoise AI (and its successor, Topaz Photo AI) uses AI, but it is generally not considered “generative AI” in the same sense as tools like Midjourney, Stable Diffusion, or Photoshop’s Generative Fill. However, the distinction is becoming less clear as AI-based photo editing evolves.
Here’s why.
Traditional denoising vs. generative AI
Traditional denoising algorithms work by mathematically reducing random sensor noise while attempting to preserve edges and detail.
AI denoising, such as Topaz DeNoise AI, is trained on millions of image pairs. Rather than simply smoothing pixels, it predicts what fine detail should look like based on what it has learned.
In doing so, it is not merely revealing information that already existed—it is making an educated prediction.
Is that “generative”?
Technically, yes—to a degree.
Computer vision researchers would describe many modern AI denoisers as generative or reconstructive neural networks because they synthesize plausible image content from learned models.
However, they differ from image generators because:
* they begin with an actual photograph,
* they preserve the scene geometry,
* they do not invent new birds or backgrounds,
* they are constrained by the existing image.
So most photographers think of Topaz as an AI restoration tool, not an image generator.
Why eBird reviewers worry
The concern isn’t whether the software is called “generative.”
The concern is whether important field marks may have been altered.
Examples include:
* faint wingbars becoming more prominent
* eye rings appearing cleaner than they were
* streaking becoming simplified
* bill shape subtly changing
* feather edges being “hallucinated”
* color transitions becoming smoother
For common species this rarely matters.
For a potential first county record, rare warbler, difficult gull, or hybrid, these changes could influence identification.
Where Topaz becomes more controversial
Recent versions of Topaz Photo AI include features like:
These functions are more likely to invent fine detail than simple noise reduction.
If a tiny bird occupies only a few dozen pixels, the software may create feather structure that never actually existed in the original capture.
That is what many reviewers are concerned about.
Current community consensus
Among experienced eBird reviewers and iNaturalist identifiers, the emerging consensus is something like this:
Generally acceptable
* Exposure adjustment
* White balance
* Contrast
* Cropping
* Traditional sharpening
* Moderate AI denoising
Use with caution
* AI sharpening
* AI detail recovery
* AI upscaling
* Super-resolution
Usually discouraged for documentation
* Generative Fill
* Object removal affecting the subject
* Adding missing features
* Replacing backgrounds
* Creating image content that was never captured
My recommendation for citizen science
If the photograph is being submitted primarily as documentation of a rare bird, I would:
* keep the edits conservative,
* avoid aggressive AI sharpening,
* avoid large AI upscales,
* retain the original RAW or JPEG,
* be prepared to provide the original if requested by a reviewer.
Many regional eBird reviewers already ask for original, unedited files when evaluating exceptional records.
Looking ahead
I suspect we’re moving toward a new vocabulary. Rather than asking whether an image is “AI” or “not AI,” reviewers may classify edits by how much they alter evidentiary content. An image used as scientific documentation should preserve the observable features present in the original capture as faithfully as possible.
As someone involved in bird photography and citizen science, you might appreciate a practical framework like this:
* Evidence-preserving edits: cropping, exposure, color balance, moderate noise reduction.
* Evidence-enhancing edits: AI denoise, AI sharpening, super-resolution—useful, but capable of altering subtle field marks.
* Evidence-generating edits: adding, removing, or fabricating image content; generally inappropriate for scientific documentation.
That framework focuses on the real issue—whether the edit changes the evidence—rather than on whether a particular tool is marketed as “generative AI.” It also provides a clearer basis for camera clubs and citizen science projects to develop consistent policies as AI-assisted editing continues to evolve.

Dear Birders,
Over the past year, several birders in California and further abroad have used artificial intelligence (“AI”) to edit photographs of birds and have uploaded those altered photos to eBird and iNaturalist. Even though most of these instances have probably been innocuous attempts to make a poor photo look a bit better, this practice is highly damaging regardless of a user's intended purpose. Unfortunately, most birders still do not understand how many of these programs work and why they are so negative. Below I have attempted to explain this issue.
There are several types of artificial intelligence, but the variety used by the most popular platforms (Google Gemini, Claude, etc.) is called generative AI. These programs have immense databases which they use to generate responses to user prompts. To put it simply, if you have a photo of a California Scrub-Jay, and you use a generative artificial intelligence program to edit the photo, the program is going outside of the data contained in the photo, searching its database for what it knows California Scrub-Jays look like, and then uses that external knowledge to “touch up” the photo to meet its expectations. This is not much different than printing a photo out onto paper and asking an artist to touch up the photo by painting onto it. The human artist will use their knowledge of what scrub-jays are supposed to look like to improve the image. So does AI.
To further clarify, I asked Google Gemini to explain how it edits photos. Here is what it told me: “Gemini is a Generator: It doesn’t actually “edit” your photo. Instead, it looks at your image, reads your instructions, and draws a brand-new picture from scratch based on patterns it knows. Because it rebuilds the entire image every time, it struggles to keep the original details—like the exact shape of a face, text, or background textures—identical.”
So, if you upload that Scrub-Jay, the generative AI can use its knowledge of scrub-jays to fill in missing details, and make that blurry photo sharp, or that dark spot visible, etc. But what if you upload a subpar photo of an Empidonax flycatcher? Or a seagull (yeah, I said it)? The AI still goes into its database and uses that external knowledge to touch up the photo… can the blurry Western Flycatcher be mistakenly touched up into a Willow? A Yellow-footed Gull into a Western Gull? Even if you upload a good photo, can the Sooty Fox Sparrow be made to look a bit more like a Slate-colored? Might a hatch-year state of molt return looking a bit more adult like? (If the number of remiges can change on a bird when run through AI, as I've seen a few times, it seems anything is possible.) How about a perfectly decent photo of an Epaulet Oriole, which when “touched up” with AI came out looking like the first-for-Brazil record of Red-winged Blackbird? More on that last scenario, and a further explanation of AI’s problems as they pertain to citizen science databases, here: https://www.nature.com/articles/s41559-026-03141-y
In short, generative AI should absolutely not be used when editing photos. These programs rely on pre-existing knowledge to edit photos, and in doing so, inevitably hallucinate details that were not actually there. At best, uploading these photos pollutes scientific databases with photos not representative of reality. (It is crazy that that is the "at best."]) And, I hate to say it, but with companies shoving AI down our collective throats, the onus is now on the user to verify that new photo editing apps and tools do not use generative artificial intelligence.
One final sobering note: Most of these instances where eBird reviewers or other careful eyed observers have sniffed out AI-altered media have done so because, to the trained eye, most AI edited photos often have the wrong number of feathers, a mishmash of features from different (sub)species, or otherwise appear "strange" or "off." But AI is improving rapidly. Just last year, I was unable to generate a photo of a bird in Google Gemini that did not seemingly combine features of multiple species and that was not positioned at an unnatural angle. Last week, I generated a photo of a Mourning Warbler with AI--completely from scratch, no pre-existing photo to serve as a "canvas" to work off of--that was scarily convincing. (I sent the photo to a few friends to ask what they thought-- the first to reply wrote, “Ok f*** this.”) Soon, we will not be able to tell what is and is not altered.
Please, build good habits now, and encourage the same from those around you by strongly advocating against the use of generative artificial intelligence to edit photos and by educating other birders of its perils.

Something to consider as photo processing programs add generative AI…

Subject: [CALBIRDS] artificial intelligence and photos of birds
Dear Birders,
Over the past year, several birders in California and further abroad have used artificial intelligence (“AI”) to edit photographs of birds and have uploaded those altered photos to eBird and iNaturalist. Even though most of these instances have probably been innocuous attempts to make a poor photo look a bit better, this practice is highly damaging regardless of a user's intended purpose. Unfortunately, most birders still do not understand how many of these programs work and why they are so negative. Below I have attempted to explain this issue.
There are several types of artificial intelligence, but the variety used by the most popular platforms (Google Gemini, Claude, etc.) is called generative AI. These programs have immense databases which they use to generate responses to user prompts. To put it simply, if you have a photo of a California Scrub-Jay, and you use a generative artificial intelligence program to edit the photo, the program is going outside of the data contained in the photo, searching its database for what it knows California Scrub-Jays look like, and then uses that external knowledge to “touch up” the photo to meet its expectations. This is not much different than printing a photo out onto paper and asking an artist to touch up the photo by painting onto it. The human artist will use their knowledge of what scrub-jays are supposed to look like to improve the image. So does AI.
To further clarify, I asked Google Gemini to explain how it edits photos. Here is what it told me: “Gemini is a Generator: It doesn’t actually “edit” your photo. Instead, it looks at your image, reads your instructions, and draws a brand-new picture from scratch based on patterns it knows. Because it rebuilds the entire image every time, it struggles to keep the original details—like the exact shape of a face, text, or background textures—identical.”
So, if you upload that Scrub-Jay, the generative AI can use its knowledge of scrub-jays to fill in missing details, and make that blurry photo sharp, or that dark spot visible, etc. But what if you upload a subpar photo of an Empidonax flycatcher? Or a seagull (yeah, I said it)? The AI still goes into its database and uses that external knowledge to touch up the photo… can the blurry Western Flycatcher be mistakenly touched up into a Willow? A Yellow-footed Gull into a Western Gull? Even if you upload a good photo, can the Sooty Fox Sparrow be made to look a bit more like a Slate-colored? Might a hatch-year state of molt return looking a bit more adult like? (If the number of remiges can change on a bird when run through AI, as I've seen a few times, it seems anything is possible.) How about a perfectly decent photo of an Epaulet Oriole, which when “touched up” with AI came out looking like the first-for-Brazil record of Red-winged Blackbird? More on that last scenario, and a further explanation of AI’s problems as they pertain to citizen science databases, here: https://www.nature.com/articles/s41559-026-03141-y
In short, generative AI should absolutely not be used when editing photos. These programs rely on pre-existing knowledge to edit photos, and in doing so, inevitably hallucinate details that were not actually there. At best, uploading these photos pollutes scientific databases with photos not representative of reality. (It is crazy that that is the "at best."]) And, I hate to say it, but with companies shoving AI down our collective throats, the onus is now on the user to verify that new photo editing apps and tools do not use generative artificial intelligence.
One final sobering note: Most of these instances where eBird reviewers or other careful eyed observers have sniffed out AI-altered media have done so because, to the trained eye, most AI edited photos often have the wrong number of feathers, a mishmash of features from different (sub)species, or otherwise appear "strange" or "off." But AI is improving rapidly. Just last year, I was unable to generate a photo of a bird in Google Gemini that did not seemingly combine features of multiple species and that was not positioned at an unnatural angle. Last week, I generated a photo of a Mourning Warbler with AI--completely from scratch, no pre-existing photo to serve as a "canvas" to work off of--that was scarily convincing. (I sent the photo to a few friends to ask what they thought-- the first to reply wrote, “Ok f*** this.”) Soon, we will not be able to tell what is and is not altered.
Please, build good habits now, and encourage the same from those around you by strongly advocating against the use of generative artificial intelligence to edit photos and by educating other birders of its perils.
