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, between Common Loon and the European name, Great Northern Diver. It sounds a little more important than a mere Common Loon, so I guess I’ll go with it.
I was reminded again how difficult feather down is to depict, as are reflections. I sometimes wonder why I torture myself so, but I was pleased with the result, so it was well worth it.
