This next adult bird is a bit problematic for me. For now, my tentative ID is a Thayer's/Kumlien's intergrade:
The wingtips looked too pale for a Thayer's Gull next to this American Herring Gull. Also note paler mantle shade and the larger apical spots. One could easily argue the bill and head size/shape fits well for Kumlien's or a fm Thayer's:
There were 3 Glaucous Gulls seen (1 adult, 2nd cycle, 1st cycle), but surprisingly, we missed LBBG and GBBG completely! The next morning, Eric Walters found 4 adult GBBGs that came in together - go figure! I'm looking forward to next year - see you then!
