Some people enjoy spotting rare birds. Well, the birds around here are pretty common. What I get excited about is spotting unusual typographical errors in my reading. I couldn’t believe my luck last night when this incredibly rare example of a double vowelswitch (Vowelswitchus geminus) fluttered into view! Some have argued that such creatures, if they ever existed at all, had long been hunted to extinction by professional editors armed with sophisticated modern software. But here was one in full plumage, effortlessly shifting from one spelling to another as I watched in amazement! I may never be so fortunate again even if I live to be a hundred.

(And no, of course I didn’t highlight in the book. What kind of monster do you think I am? The red and green marks are purely digital additions to the picture I snapped. No rare texts were harmed during the production of this post.)
