Pair of immature Glaucous Gulls, Weld County, Colorado, 4/07. I believe
that the right bird is a 1st-cycle individual, and the left one is a 3rd-cycle.
Additionally, the older bird looks bigger, probably a male. California,
Ring-billed, and Herring Gulls are also in the frame. Click here for a
close-up crop of the two Glaucous
Gulls. |
