Sandy Sorkin saw a Sora (albeit a distant one, second from left) this morning on a Phrag island near the beginning of the Marsh Discovery Trail at DeKorte Park.

Below is a map to give you an idea of where it was. They have also been seen at Phrag's edge near the start of the trail. Your results may differ. (Orange line is the MDT, black dot is the trail entrance.)  (Thanks, Sandy!)
