I'm awfully late to the picture, but this fella has been around for the past week or so. Maine is killing it on the rarities again this year, I don't know if that's something to be afraid of.

Was it all yellow? If not, how about a Yellow-headed Blackbird?

We have marmots in New Mexico too. (By the way, @HamRHead, woodchucks are marmots.) Yellow-bellied Marmot by Jerry Friedman, on Flickr And ground squirrels. Queen of all she surveys by Jerry Friedman, on Flickr And more glamorous mammals, but I didn't get any pictures of the bear I saw a few weeks ago.

Since the forum came back I've been trying to think of what threads we had, this was one Fire on the north rim Grand Canyon Kiger Gorge Steens Mountain, Oregon

Is this a Cassin's Sparrow? NW New Mexico today. Thanks. https://www.dropbox.com/sh/km19hex1vap0kfs/AAAI4_KjPhlACMB8LNXU7Y1Ca?dl=0

My son's photo from yesterday--frog on a kayak paddle.

Yes, or maybe an escaped kazoo?

Drone?

Here is an image of the Nu'upia Ponds WMA. Awesome birds here!

Are you sure it was yellow? Could it have orange? Rufous Hummingbirds should be down here by now

Incidental today, Augusta GA. Possibly two birds. Bird 1-5: This has me thinking Common with that dark primary wedge, although the bill looks black. Bird 6-10: Is there any chance this is the same bird as in 1-5? On a fairly large body of water I shot several sequences of what I thought was the same bird making passes. Upon looking at my photos I am wondering if there was a second bird. I definitely lost track of it several times so perhaps...

This is a classic Cooper's Hawk. Like you said, tail is too long for a Red-shouldered.

Another wild guess would be Peregrine Falcon.

I have no problem seeing the first as a Common. Lots of ours now have black bills. 1st summers. 2nd set looks likely to be a tern. I am not good enough to say more from those pictures.

Agreed.

Leg color is something to be careful of -- it can be obscured by mud, etc., and can be rather variable in youngsters. Don't know where you got the "eyebrow means semi" line -- that's simply wrong. In this case, the extensive rufous on the scaps and tawny-rufous on the wing coverts coupled with the nice, clean, crisp juvenile plumage say Least as well as the legs. Semi's lack extensive rufous above in this plumage, and Western have distinctly gray wing coverts.

They both look like Least to me.

this is fine. more people will see it here

with yellow-green legs, it's a least

Worn, faded feathers tend to have frayed edges and markings that are blurred, low-contrast, etc. Fresh feathers have crisply-defined edges, often with a bit of contrast, and clean, crisp, contrasty markings -- when you get the two together, the difference shows up nicely. Other diagnostic marks? The pink legs do help, although you have to be careful of leg color in youngsters -- a first-year bird especially can surprise you. Similarly, the bill pattern does fit a young Herring, although the structure is a better clue -- fairly heavy with a distinct gonydeal angle. Also, young Ring-billed should never be mottled on the undersides -- the breast and neck have very clean dark scaling, the belly tends to lose that pretty quickly and ends up white. The back in juveniles is well-marked, but even then it's very clean and regular, with dark centers and pale edges to the feathers, rather than the anchor-shapes you see here. A lot of ID'ing immature gulls, though (except for a few experts), comes down to elimination by range. Fact is, there are several European species, etc. that I couldn't possibly rule out here -- but they're very unlikely to be there, so I don't worry about it. Given the location and date, the other options are Great and Lesser Black-backed and Laughing. Laughing is quite different even as a juvenile. Great Black-backed should be overall bulkier, with a more checkered back pattern and a whiter head, and a heavier bill. Lesser is closer to this, but they shouldn't show so many warm tones in the plumage, and be a bit whiter on the head. Can't help you with the programming side of things -- I can understand the general idea of neural networking, but I couldn't explain it any better than we can understand how it happens in our own heads.

Has anybody seen a fish?

OK, thanks. I haven't been up to Colusa NWR since Spring. Just my luck!!
