You spot a small bird with bright yellow feathers on your back porch. which one of the following books might be a good place to find out what kind of bird you've seen?

If the options are: 

A. Bird Feeders for Fun
B. How Geese Find Their Way 
C. North American Birds Illustrated 
D. The Anatomy of Birds

The answer is C. North American Birds Illustrated. As you don't know what is the bird called, you can find it by the picture, and see what kind it is. You don't need a humorous account of bird feeders, nor is this bird a goose (obviously). There's no need to take a book on birds anatomy either.
