While looking for the possible Yellow-legged Gull late this afternoon, we (Willie D'Anna et al) observed a first winter Glaucous Gull and an adult Kumlein's Gull mid-river and a probable Lesser Black-backed x Herring Gull Hybrid on the Breakwall. In fact the probable hybrid did superficially show some similarities to an "atlantis" Yellow-legged Gull (head-streaking and mantle shade) except that since it was asleep the bill or legs were not visible! I have seen Josh's photo since and we were definitely seeing different birds.
The key to finding rarities on the Niagara River is development of extensive experience on the enormous variation in American Herring Gull, Lesser Black-backed Gull and any possible hybrids.
