Great Northern Loon ~ Gavia immer
Apparently what I grew up knowing as the Common Loon has now been renamed the Great Northern Loon (though Gavia immer remains its scientific name). A compromise, I believe, with the European name Great Northern Diver. It sounds a little more important than the mere Common Loon, so I guess I'll go with it.

I was reminded again how difficult down is to depict, as are reflections. I sometimes wonder why I torture myself so, but I was pleased with the result, so I guess it was worth it.
