Lesser Black-backed Gull (Larus fuscus)
Above two: Adult Lesser Black-backed Gull at the Salisbury Landfill, Wicomico Co., Maryland (2/24/2006).
Below two: Perhaps the strangest near-adult Lesser Black-backed Gull I've seen. It might fall somewhere within the expected range of variability for a bird going into its third winter, but I've never seen this combination of field marks before. In second image, it is seen with a very different third-winter Lesser Black-backed Gull (Assateague Island, Maryland, 11/16/2008).
Above and all but last two photos: Several of the then-unprecedented 16 Lesser Black-backed Gulls discovered
on Assateague Island's ORV zone on 6/5/2005. Various summer plumages shown.
Above and below: Nice comparison of juvenile Great and Lesser Black-backed Gulls.
Below: One of many Lesser Black-backed Gull that followed us off Maryland (2/5/2011).
Below: Photographed at North East Town Park, Cecil Co., Maryland (3/6/2005).
Below: A presumed adult Lesser Black-backed x Herring hybrid at the Charles Co. Landfill, Maryland (1/29/2011).
