Glaucous-winged x Herring Gull
adult
Fig 1) Based on the dark in the bill, this bird is probably a fourth year bird (but we'll put it on the adult page anyway). It seems much like a Herring Gull, but look at the underside of the folded primary: it's basically white. This bird would seem quite white-winged in flight from below. The very pale eye, bill shape and rather light mantle shade point away from Gl-W x Western and toward Gl-W x Herring. The head and neck streaking are also Herring-like, though washed out in the photo. 27 November, Palo Alto Baylands, CA; Mike Rogers. Copyright 2000.
