A Potpourri of Herrings: Chicago

I had an hour to "kill" on Sunday and so got out to one of my favorite sites on the Chicago lakefront, Calumet Park, for some Herring flight shots. Every age was recorded with a few neat sub-adults.

By far my most interesting HERG was this 2nd/3rd cycle type. Most of the flight feathers (secondaries, outer primaries and rectrices) are okay for a 2nd cycle, but the inner primaries are adult-like, and likely 3rd basic.
