January 29th 2007.  Turner's Falls Power Canal, MA.
Unidentified Gull. Larus sp. 1st cycle.

This large, tricky, first-winter gull flew into the power canal towards dusk to rest and bath for a while. Mark Taylor and I also saw the same bird on January 30th. First impressions were quite Thayer's like, but I'm wondering if it may be a  smallish, dark smithsonianus x hyperboreus hybrid - Nelson's Gull?  Comments are always welcome.
