Like all of the Elephant & Piggie books, There is a bird on your head! has the feeling of a comedy skit. The background for every page is left completely blank--white, leaving the reader to focus entirely on the two main characters, Gerald and Piggie, and their frantic exchanges after a bird happens to land on Gerald’s head. Whether you’re talking about movies or books, this Willems title is a reminder that what’s most important for a good story is the idea, the writing. That’s why there’s no special effects here. They aren't needed, and there aren’t any shortcomings to hide. 57 pages.
