Just to prove that I'm not making this up, here's an interview with me in the Chicago Tribune, and a mention in the New York Times, and an extract in the Huffington Post. It's published by Berkley Penguin. Penguins being biologically from Antarctica, and etymologically from Wales*.
The Newfoundland Auk promptly became extinct. The name would have died with it, were it not for the fact that the auk looks very like the unnamed birds that were pottering around at the south end of the planet. That picture on the left is an auk, so you can see the similarity.
Thus the Welsh for white head managed to make it to the other side of the world. Berkley, on the other hand, means clearing in a birch forest - leah was the old English for clearing, and beorc was birch. So Berkley Penguin is, etymologically speaking, a great auk standing in a birch forest.
I've searched, but can find no illustration for this.
Anyway, run to the shops and order your copy now. Or click on this link and buy it from Amazon.com.
So stylish
