Subject: [slocobirding] Seek photos
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!

- Media: 4 Photos
- 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."

- 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."

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).

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.

White forehead, forecrown and nape; dark central crown with a dark extension down the middle of the white nape and down to the auricular area, giving the appearance of a black skull cap; dark spot in front of eye; black patch on the side of breast; gray back and slightly notched tail; gray wings above and below with a darker leading edge on the upperwings; white underparts; all black bill.
It was observed flying with Forster's and Elegant Terns along the length of both sides of the pier. It was flying with steady wing beats. The flight pattern was quite erratic and it was not seen diving into the ocean, as the other terns were."

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.


Found late this morning by Kathi Marston who also found a Black Tern a few mile to the north at Morro Strand State Beach on 13 Aug 2026."

This was a medium-sized peep that was slightly smaller than the Westerns it was associating with, exhibiting an entirely dark medium-length bill (on the longer side for a Semi) that was evenly thick and traffic cone shaped, dark lores, a pale split supercillium, dark eye, thin, barely noticeable eyering, and a pale rufous crown and cheek. The scapulars and wing coverts were dark centered without any rufous fringing. The legs and toes were dark. Shortly after the flock flew in it flushed and so did the Semi. It would return by itself two more times but again flushed rather quickly each time and did not allow very close approach. It was silent to the best of our knowledge. As mentioned previously this bird had a rather long bill, which indicates this bird is likely a female. Photos"

Subject: [slocobirding] Offshore Boat Trip
A unique pelagic birding opportunity is scheduled for Thursday, Aug 27. The Starfire will travel ~40 offshore with the goal of reaching the continental shelf. It will be a 10-12 hour trip and the cost is only $210.



This season’s warm water associated with the building El Nino could potentially turn up something unusual.



See the announcement below for more information.

They were coming to oriole feeder 2 to 4 times a day. A female, what I

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.

Subject: Re: [slocobirding] Hooded Orioles on the move?
I saw what I call the Patriarch of my summer Hooded Oriole family this morning drinking out of one of my hummingbird feeders. I hadn't seen him in a number of days.A few of the juveniles showed up at different times to do their drinking.Based on prior years, they will be leaving soon. 🙁Dawn BeattieMorro Bay

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.

Subject: Re: [slocobirding] Hooded Orioles on the move?
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.
Best, Ron Hirst Santa Barbara

- 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."

- Comments: "*Rare but regular. 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."

- 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…"

Subject: [slocobirding] Blue-gray Gnatcatcher yb
[Edited Message Follows]

Twice this week a Blue-gray Gnatcatcher has been spotted gleaning tiny insects in my unstructured, mostly-native garden.  Today it was an all-you-can-eat buffet of Rose Sawfly larvae on my climbing roses.  I leave the chemicals on the store shelves and the pruning shears to get rusty.

Subject: Re: [slocobirding] FW: [CALBIRDS] artificial intelligence and photos of birds
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.

That means it can:

* reconstruct feather barbs
* sharpen eyes
* recreate subtle textures
* remove noise while maintaining apparent detail

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:

* Super Focus
* Recover Faces
* Upscaling
* Detail enhancement

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.

Thank you
Ethan Monk

Medium-sized, adult tern, with entire upperparts blackish (crown darker shade of black), except for prominent white "headlight" on forehead, and white-edged outer rectrices of deeply forked tail.

While sitting on the beach, presented as having long wings and a very low profile. Much as the Dockweiler bird did last year, this one appeared to want to hang out at the edges of the flock. A one-day bird, as is typical for Sooty Terns in California not associating with breeding colonies."

Hope this helps! And, as always, if you can’t make it tonight, you can always catch it on the rerun at the project’s YouTube channel. I’ll posts a link to it when it comes out, early next week.

Bird on!
