I forgot to add that there was a flock of 400-500 Ring-billed Gulls, all adults as far as I could see, along Fir Island Road not far west of the Skagit River, feeding next to big flocks of Snow Geese. I had never seen that many Ring-billed Gulls at one time in Washington and considered it as amazing as the goose spectacle that we had been watching.
