I forgot to include the link to the photo of the birds http://www.flickr.com/photos/dobak/112719998/
Above the photo is a little button to get "all sizes" so you can enlarge it a bit. Also, I have no idea why I said that Black Dog doesn't seem like the type of lake to have hybrids. I have been informed that since it doesn't completely freeze during winter it collects many hybrids from all over the Twin Cities. Anyway, thanks for any help you can offer. Derek
