A typical Glaucous-winged has primaries that are nearly the same darkness as the body, sometimes a bit darker, but never this dark. I would be comfortable putting this one into the Glaucous-winged x Western gull hybrid camp. Also note how most of the grey is still focused on the mantle, with little on the wings, and the bill is still rather dark and the tail shows substantial dark. Due to these features I would also put it into the 2nd winter age class rather than 3d, by their third winter they look mainly like adults with some brownish smudging here and there, but not so much brown, particularly on those wings. I spent the morning digiscoping gulls here on the coast, there were some real weirdos out there, I will be sure to put some of these up on the Internet soon. regards Al Alvaro Jaramillo Biologist San Francisco Bay Bird Observatory P.O.
