Just in case anyone's interested in this, a Ross's Gull was found this
morning off the Swimming Beach at Lake Yankton along the Nebraska/South
Dakota state line, not far from Sioux City, IA.
The Denver Ross's Gull was also still present this morning as well.
That makes two Ross's Gulls within a week of each other! Might want to
double-check all Bonaparte's Gulls.......
Happy Birding! --Chris W, Madison, WI
