Details
One first-cycle, one adult (or maybe two, but more likely the one just moved between sightings). Both birds visible in this photo, but the adult is a bit hard to see, hidden behind some California Gulls in the left part of the upper right quadrant: A closer view of the adult:

Details
An uncommon species here, but this is by far the "expected" subspecies. One second- or third-cycle, three different adults. Similar to other earlier counts from this location. Subspecies confirmed by relatively pale gray mantles, a bit darker than California Gull and not nearly as dark as Great Black-backed Gull. I only photographed the immature bird. The adults each had dark gray mantles darker than adjacent California Gulls, long body shapes, red and black on the bills, and bright pale eyes with flecking in their white heads concentrated around the eyes. One was on the pond by the road, and the other two adults were in the back pond, at separate ends of the large flock. I scanned over each of the three adults at least twice to ensure it wasn't just one or two birds moving around, and they stayed in place during the time I was checking.

Coarse eyeball estimate. More likely too low than too high.

Number observed: 4
Details
Two first-winter, two adult. Probably more if I had looked at the rest of the gulls more carefully.

Number observed: 1
Details
Pretty pale wingtips. Seemed to fit either a darkish Kumlein's Iceland Gull or perhaps Kumlein's x Thayer's hybrid best, too pale and lightly marked for pure Thayer's and too dark and densely marked for glaucoides Iceland or pale Kumlein's Iceland Gull.

American Herring/Iceland Gull
Number observed: 1Details
Either a very petite Herring Gull or a very pale-eyed Thayer's Gull, and I'm leaning strongly to the latter. Bright pale eyes with no visible flecking at all, dove-shaped head, thin and short bill (for this species pair), solid deep black in wingtips.

Details
This is the expected subspecies in the winter in northern Utah, and the filter should be changed. Mountain White-crowned Sparrows are expected here only in the breeding season. I noted the pale lores and orangish bill.
Details
Not visible from the road, but rather on a second pond further back (east) that required a bit of a walk to see and access. Continuing first-cycle bird. First state record, originally found by Matt Pendleton on Wednesday and pointed out to me today by Michael Lester. Photographed (digiscoped): Precise location about here:
Accepted by the Utah Bird Records Committee as the first state record.
