Carpentersville Dam – 12/24/2016


    We started out again at the Otto parking lot finding twenty Eagles. Then, we drove up to the Dam where we spent a longer time scanning through the Gulls then last time. We were rewarded with six Thayer’s Gull, a Lesser Black-backed Gull, and the second winter Iceland Gull. After we scanned the Gulls thoroughly, we walked down the path finding about ninety Goldeneye, fifteen Mergansers, and some more Eagles. We went back  to our car and drove down to the Fox River in West Dundee. At the first stop (northern most parking lot on Lincoln Avenue between Otto and Washington St.), we saw just some Gulls. As we drove down Lincoln Avenue, we also saw some Gulls. I did a quick scan of them and found a third winter GREAT BLACK-BACKED GULL. We watched it for about fifteen minutes to make sure that it was not something else. While we were watching it, we saw it steal a large fish from a Herring Gull.

UPDATE : The 2nd year Iceland Gull was Identified as a Herring x Glaucous Gull Hybrid
