Seen in Grover Beach, CA today while watching a continuing snow goose. Seemed different...loved being fed, hungry, too! 2 birds, pic 3 is a different bird than the others. Have plenty more pics if needed...

Pic 3 is a Glaucous-winged Gull, due to the pale brownish-pray primaries. Thayer's Gull is ruled out by the generally diffuse patterning on the coverts which would be more distinct in Thayer's.

The other bird my first impression would be Herring Gull but I am taking some time to consider the various Glaucous-winged hybrids.

The odd bird out is, indeed, an immature Glaucous-winged. I'd go with a Cook Inlet Gull (Herring x Glaucous-winged) for the star of the show.

1) The underside of the wingtip is too pale for a pure Herring

2)The bird is too big with a too-big bill that is not all or virtually all black for Thayer's ["Iceland Gull (Thayer's)" in eBird parlance]

3) The tail is too dark and too patterned for a pure Glaucous-winged.

See here, somewhere, for a similar bird or two.
