The book Wild & Wacky Birdhouses and Feeders by Paul Meisel incorporates plans for whimsically styled squirrel feeders — a player piano, anyone? — and birdhouses ranging from a football helmet that can be customized to your favorite team to a crowing rooster or cartoon kids. (The author encourages real kids to get involved in the projects.) The book also includes hints on squirrel control, birdseed, perches and more.
