Lesser Black-backed Gulls/Drake Lake (and "Chicken" challenge)

[The "Nunn Guy"]

Hi all

This morning had four Bald Eagle (2 ad, 2 imm) at WCR 84/31 marsh and 3 Lesser Black-backed Gull (adults) with 2 Herring Gull and host of Ring-billeds at Drake Lake.  We were in Nebraska last four days ("billions" of Snow Goose-no cranes) and while out one day my wife noticed five "black things" in a corn field.  We stopped and looked at them and my first reaction was "Greater Prairie Chicken" (6 of them) can someone confirm by these photos? ==>
