Gull i.d. Oregon

I'm hoping someone can identify these gulls found in northern Oregon.
Thanks.

I’m thinking 1st Winters Glaucous Gull for 1.and Thayer’s Gull for 2.

Cheers

2. a 1st cycle mew gull, Larus (canus) brachyrhynchus

....I thought 1st Winter Mew Gulls had Barred UTC’s and much darker brown remiges or is it more advanced moult?

Then it's high time brachyrhynchus was split from canus!

Mew's remiges (and tertials) usually do appear much darker than shown here, but sometimes they appear like this. Here's an example of of a similar bird (though maybe not quite as light):

I also think the exposure and lighting are playing an effect in the gull in question.
