|Glaucous-winged Gull (Larus glaucescens) Gulls, Terns and Skimmers (Laridae)|
|Gråvinget Måge Gaviota Alas Blancas|

Juvenile. Apparently a classic pure bird without hybrid tendencies. Only bird present of this species among thousands of Western Gulls.

Juvenile. Unsure about the purity of this bird. Perhaps the bright backlight makes the bill look paler than it is - that it looks slender is caused by the angle of the head to the camera. The remiges look good for a pure bird, but the greater coverts are perhaps a bit too mottled, but not sure if it appears so because of the bad photo quality.
