Welcome to the desert

"Why is a hummingbird visiting a spiky cactus? How does a Gila woodpecker help a huge saguaro cactus stay healthy? When a prairie dog family moves to a new house, who takes over their old burrow? And what hairy, eight-legged desert creature uses a hidden trapdoor to catch its meal of beetles? Packed with facts, core-curriculum information, and fantastic photographs that support the text, this title takes readers on a mini safari through a desert. Like piecing together a jigsaw puzzle, readers will discover how the living things that make this habitat their home depend on each other and their environment for survival"--From the publisher's web site.
