It's a Peregrine.

I think you're correct on everything you guessed, and the blackbird looks like a Brown-headed Cowbird.

Swainson's. The best ID point for me to use personally is the buffy eye ring.

Orange-crowned Warbler.

Looks good for Yellow to me.

This incredibly confuses me. It has a 'flaring' supercilium and less dense breast streaking, which are traits I associate with LOWA. But then it has streaking on the throat, which I associate with NOWA. Is a hybrid possible?

Female Brown-headed Cowbird.

I can’t think of any bird that matches your description, particularly given size.

Could just be wash from the water, or maybe pigmentation due to feeding, but I’m not sure.

Seconded

Both are domestic. The first looks like it has Swan Goose in it, and the second seems to have Greylag in it. Probably mixed a bit, though.

Looks like a messy Sharpie to me.

Western Wood, I think. In my experience, Olive-sided is much more bold.
