The bills seem on the long side for SESA. and if these are recent pics then WESA seems more likely as AlexH mentions?

These look a bit more like Semipalmated to me. Flatter back profile, a little darker eye stripe, not as front heavy as Westerns appear. any phoros of the bills?

The small white tips on the primaries are also a decent Herring mark.

1. yes 2. green-winged teal 3. a plastic decoy? 4. pass 5 and 6. ring-necked ducks

Primaries do look a bit dark for Glaucous-winged, perhaps suggesting some Herring influence, but other features look good for G-W (short wing projection, dark eye, pale bill base, and smudgy head and neck markings vs. darker streaking/flecking in Herring)

Interesting - - Birds of North America says definitive (adult) plumage reached at one year. Wheeler says subadult plumage at one year (rufous color on nape and auriculars, with some juvenal feathers retained on upper coverts and rump), and then adult plumage at two years with gray nape and auriculars. BoNA provides no such detail. I'll go with Wheeler.

Looks good for Greater.

I don't hear song sparrow in there.

Looks like Sharp-shinned.

They gain their definitive plumage (adult-like) in their second summer (1 year old). So this is a different bird than last year.

The first two pics appear to be Lincoln's. The fourth pic with those chestnut patches and white-fringed secondaries looks like Swamp Sparrow. I presume the third pic is the same bird.

Yes - AMGO. White undertail eliminates LEGO.

A combination of marks; For the first-cycle bird, you see an all-black bill that is not evidently large or bulbous, the head profile is fairly rounded rather than a long sloping forehead, pink legs, and the wingtips are about the same color as the mantle (although some Thayer's can have darker wingtips), with narrow white edging on the primary tips. For the adult, a non-massive bill with red gonys mark (no black ring), fairly light-mantled, same head profile mentioned above, pink legs, white-tipped primaries.

These look good for Thayer's. The adult is a light-eyed example, which comprise about 10% of the population according to Sibley, and about 20% according to Howell.

I am leaning to a first-cycle Mew for the young bird here. Pale greater coverts with brown spots. Bill pattern. I also considered second-cycle Thayer's from the primary patterning, but they should have darker coverts. Bill looks a little dainty for Thayer's also. Get some other opinions.

The white collar and dark breast are good Cackling marks.

Far right edge of the 6th photo from top. Looks rather redhead-y.

The black wingtips rule out Glaucous. The right gull appears to be a 3rd cycle Herring. The left adult is either a Herring or possibly an Iceland Thayer's.

Looks good.

Yep. RNDUs

Looks like a redhead in the last two photos.

Although a bit out of range, Yellow-bellied may be a possibility. The tail looks on the short side for PSFL/COFL.

Western seconded, for the same reason akandula notes.

Probably House Wren with the grayish underparts as shown.

Isn't this just a nonbreeding male house sparrow?
