About 3 months ago I posted about my experiences back in Jan 1999 spending many early mornings at the fabulous Sauvie Island Pellet Plant (RIP), initially looking for Slaty-backed but very soon recognizing what an opportunity this was and then just studying gulls.
I said I would try to go through my many scanned slides and put together an armchair summary. Well, it turned out that I had only scanned in the 'best' ones so the rest remain to be scanned. But I thought I'd finally, first, show the 'best' ones in a few posts over the next month or so. My new year's resolution is to get this PP stuff finished before 20 years have elapsed. I have about 350 days to go.
There were several goodies but here is the best bird, I guess, pending OBRC acceptance. This bird was present for several days. I called him the BigGuy in my tape recorded photographic notes. (Fortunately I transcribed them before losing the tape, 35,000 words). One of the photos shows a size comparison (the wing tips and bills lined up) to an adjacent Glaucous-winged or hybrid. If the BigGuy's bill was horizontal it would extend further. Also notice the bulbous bill tip relative to the GWGUs. It seems to be a 3rd year bird acquiring the black back. I tried initially to make him into a Yellow-footed Gull (Salton Sea that I had recently visited) but in the end had to settle for Great Black-backed. (pending OBRC of course).
I find 4 western US records, one in each of 4 states, on eBird.

GBBG was picked about 6th or so for the next Oregon Bird in the recent poll.
