I saw a pair of these yesterday. This is the best frame I got. Spotted in northern Illinois, near a large pond, small river, and 5 miles from Lake Michigan. I also posted this to the local forum, but with 45 views, no takers yet. Thought I would try the larger audience here. I've been birding for about a year, and have guess what it is, but it's FAR fetched. Suggestions?
