Chris, I'm bringing in a starfish ID book from home, and, if no one else
has done so, I'll try to identify the starfish in the photo next time I'm
in my office. It may be Pisaster ochraceus, the common starfish of the WA
outer coast, and the prey in all gull/starfish interactions I've seen on
the coast (and indeed it's replaced by Pisaster brevispinus in Puget Sound)
but it seems a bit robust for that species, so I'll withhold judgment until
I check other species. It's certainly a glaucous-wing, as you surmised.
No wonder beginners have trouble with identification; in some of the older
field guides, hardly any of the info on gull identification was entirely
accurate.

I recall another misidentified bird in Terres, the "bristle-thighed curlew"
that's actually a whimbrel.
