Those large white patches are not far enough out on the wing to be a Lesser in my opinion.

It was with a juv male Rose-breasted (red underwing coverts). Rare, but not possible to rule out by range

Ah yes I always forget date and location.

I think everything points to female RBGR, except maybe darkness to upper mandible, but that is only really true in breeding season it seems like? Streaking is bold and across breast. Head stripes really distinct white, very few orange hues.

Generally universities and organizations will have a permit that allows them to handle and collect dead birds. That permit allows for possession of specimens collected by others. So it is illegal to keep feathers and dead birds, but as mentioned by @chipperatltotally legal to bring a dead bird to one of these natural history collections. (this is in the US)

A nice Palm Warbler!

Makes sense. Thank you!

It didn't call, and I see features of both dowitchers. The scapulars lack white and seem to be alternate plumage, but need help

The buffy and reddish feathers on the wings is a major difference in coloration. Also the back is not green like in a green heron.

Yes, Least Bittern

Considering that the only thing off on this bird is the apparent darkness on the auricular, I think it is probably tough to call it a hybrid especially considering it is in shadow. The breast doesn't seem to have much yellow on it. The scapulars aren't streaky greenish at all, and the sides are classic hermit warbler imo. Edit: I do think your instincts are good and it is surprisingly dark in the malar area as well, just I am not seeing any examples of birds called hybrids that did't have more features intermediate.

Voting long billed on the dowitchers. Seem to be in full alternate plumage and the white edging/tips of the scapular feathers is pronounced, also they seem round and bulky.

Thanks, thats a cool tip.

Actually I think I'm wrong on the wing coloration, maybe thats just an immature differentiator. But the 3rd pic does seem to show a bill coloration that works better for forster's

I'm thinking that the wings wouldn't be as uniformly white in a common, and the bill would be more or less entirely red considering its breeding season time

I am having trouble with a hummer I saw today, I won't write a paragraph, but more or less I have narrowed it down to fem/imm black-chinned vs anna's. This is a location where BCHUs are not surprising, but there are a few anna's around as well. Structurally it seems not as compact as an anna's and it seemed to have white tips to all tail feathers. Behaviorally it did not seem like the anna's up there, it flew up slope like a migrant, stopped at some sticky monkey flowers and was on its way. Here is the link to the list with the images in it: https://ebird.org/checklist/S108909485 Thanks!

Coffee berry is the type of habitat I would expect from a MacGillivray's.

The neck is compressed down and making the body look big in relation if that is what you mean

I do believe that is a Western x Glaucous-winged Gull. Darkish, but not faded black primaries and more uniform mantle than a pure western. Thickish, fully black bill rule out herring x glaucous-winged

likely a greater, but yeah not a great idea to call based off this one angle

thanks for the input @AlexHenry

Personally I think the thing that makes them look so different to me is where the crown ends on the back of the head on a white crowned. In a RCSP it continues down into the nape.

Saw this one in Santa Cruz, California

Pretty sure the first is a Coop due to the darker crown compared to nape, also the legs seem sizeable and I can see one outer tail feather that is shorter. The second is a Red-tail, but it may be a dark morph because it is lacking the white in its scapulars although this is variable I have heard. You can see its clean brick red tail that is standard for most adult calarus birds.
