A quick stop at Hammond Marina produced 2 adult type Thayer's, 1 Glaucous and 1 Great Black-backed among some 80 Herring Gulls.
Today was a big reminder of how terrible photographing gulls on water could be on bright sunny days. As is often the case, there's either too much light or not enough!

| Same individual above - may be an individual seen at Calumet Park in Chicago earlier in the afternoon. |
I missed my target bird here (a reoccurring Kumlien's adult), but was rewarded with an adult type Glaucous and Great Black-backed. Notice the outer primary and central secondary molt on the GBBG. Could this be an indication of a more long-distant migrant?
