Amazon.com Review
Another bizarrely humorous book from the delightfully eccentric mind of Burton Silver and company, perhaps best known for their Why Cats Paint series and related books.

The full-color illustrations of splattered bird droppings in this handy glove compartment guide enable the motorist to identify quickly which species created which display on the windshield. The excreta of a wide variety of avian species are fully described with detailed notes on the animal's food, geographic location, and the best methods of starting a collection. An invaluable companion for all those who wish to learn more about birds and what they do. Inhabitants of Europe may wish to search their used bookstores for a copy of The Comprehensive Field Guide to the Ornithological Dejecta of Great Britain and Europe which is, unfortunately, out of print.
