Fratercula arctica

The eminent physicist R.W. Wood is well remembered for his work Physical Optics, published in 1911. I always had a paperback handy and used it well into the 1990’s. In 1907, Wood published How to Tell the Birds from the Flowers, A Manual of Flornithology for Beginners, illustrated by the author. His discussion of the puffin follows:

Upon this cake of ice is perched,

The paddle-footed Puffin

To find his double we have searched,

But have discovered—Nuffin!

The puffin is the only creature in the book that has no double.
