Gulls change their plumage dramatically from year to year, and from season to season. This young gull was seen in Seattle, on the shore of Puget Sound. It's perhaps one year old, at the end of its first cycle, just starting its second cycle. This bird may be a glaucous-winged gull, possibly a hybrid with a Western gull.
Scientific name: Genus Larus, species not determined
Thanks to Sarah Toner for the gull identification and aging.
