Perhaps pollen? Though I'm not sure why a Mockingbird would have pollen

This is not identifiable. Focus on learning to identify birds through binoculars first. Not all birds that we see are identifiable, even for advanced and expert birders.

This is a pale Common, the overall impression is Common due to the bill, and the UTC have far too much streaking for Hoary.

I don't think this is a Ruddy Duck, but it is not identifiable.

This is a female duck

As someone who lives in the midwest and sees both swans fairly often, my impression is Tundra for the birds in the first image. Size differences can be hard to judge, particularly because telephoto lenses tend to 'flatten' large distances, making it hard to compare sizes. That said, the rightmost dark-billed swan is clearly smaller than the Mute, and the way it's holding its short neck is classic Tundra IMO. I think the second photo is Tundra as well, but it's a little unclear.

The bird looks to be a female type, and the hood is not really well defined if there at all. As we discussed in a previous thread, it's doubtful that female cismontanus is even separable from female Slate-colored. And this seems perfectly within natural variation of pure female Slate-colored.

FWIW, I think the angle makes the bill appear deceptively small/short. I would probably lean Herring because of the bill, but it's not necessarily a straightforward bird.

Why? The wingtips are, as well as I can tell, black. I think the issue with that one is ruling out Western (and perhaps Herring).

The bill is Mountain-ish, and the plumage certainly is in range of Mountain. It's hard to judge the primary projection- in one photo it looks very short, in another it looks long. That said, unless the photos are misleading (they do look rather unsaturated) Eastern would not be this drab, particularly this time of year when there are no juvenile birds. Technically I don't know we could rule out Western but that is much rarer; I'd call this Mountain.

Structure rules Merlin out, and may rule Prairie out, though it's not a species I see often so I'll defer to others on that one. Either way, it's almost certainly a Peregrine given the location.

I won't weigh in on eye color as I don't have extensive knowledge of that off the top of my head.... But, all the females in this photo are rusty in coloration, and have a strong eyeline. It's classic Rusty, and completely incompatible with Brewer's. A common mistake when birding is to focus one particular field mark while ignoring the bird holistically. Also, FWIW, Brewer's are commonly mis-IDed in the east (and the reverse out west). Yes, Brewer's is possible, but Rusty outnumbers it 1000-1 and it's a tricky ID to make.

All females are Rusties, and all the males almost certainly are too, though technically I don't think they're identifiable from the photos. It's still very early for Brewer's in the midwest.

Connor is correct, this is a Summer Tanager. The massive bill alone rules out Scarlet, but if that's not enough notice the light wings, where on Scarlet they would be dark.

It's a joke ?

Likely an intersex bird

The first is a Fox Sparrow, and I believe it's of the Sooty subspecies, though I'm not an expert on Fox Sparrow subspecies and I'm sure there are west coast birders who could tell you for certain. The second may be ok for pure Glaucous-winged considering the light primaries, though it is a bit dark and dingy overall.

I can't imagine that Zone-tailed Hawk is common either- it's generally an Arizona (plus texas and nm?) specialty, and I don't think there's really a good path of habitat leading all the way into California.

This is a Canada, Cackling are smaller overall with a much stubbier bill. The gull is a Great Black-backed Gull.

There is American Crow, Downy Woodpecker, and Song Sparrow in that audio clip, but the bird you're asking about is a Song Sparrow.

Ehhh.... That white is kinda borderline between the two species, but all things considered I also think it's a Lesser.

This is not identifiable

That bird's gorget is longer than Aiden's, and unlike Aiden's bird that clearly has clean white below the gorget. I'm personally just not getting a hybrid calypte vibe but you're more attuned to the subtle differences than me considering it's been about a year since I've seen either.

3 and probably 4 are Blue-headed Vireo as well. 6 is not identifiable on its own, however Chipping Sparrow was my guess and seems reasonable given the tail.
