@Chrishallbeck Happened to me the last time I read a dead-tree book. I swiped the lower right corner to turn the page.
Won't happen again as most books these days are set in smaller font type I have difficulty reading. So it's eBooks from now on. It's also saving on my bookshelf space.

but the theoretical benefits of this would not be enough to identify the bird
