Sometimes Cracker remembers when she was younger, and her previous owner would feed her hot dogs and let her sleep in his bed. That was nice, too. Rick Hanski is headed to Vietnam. There, he's going to whip the world and prove to his family and his sergeant -- and everyone else who didn't think he was cut out for war -- wrong. But sometimes Rick can't help but wonder that maybe everyone else is right. Maybe he should have just stayed at home and worked in his dad's hardware store. When Cracker is paired with Rick, she isn't so sure about this new owner. He's going to have to prove himself to her before she's going to prove herself to him.

    Since that time he has answered thousands of questions about birds, both at his store and while walking down the aisles of the supermarket. The questions have ranged from inquiries about individual species ("Are flamingos really real?") to what and when to feed birds ("Should I bring in my feeders for the summer?") to the down-and-dirty specifics of backyard birding ("Why are the birds dropping poop in my pool?"). Answering the questions has been easy; keeping a straight face has been hard.Why Don't Woodpeckers Get Headaches? is the solution for the beginning birder who already has a book that explains the slight variation between Common Ground-Doves and Ruddy Ground-Doves but who is really much more interested in why birds sing at 4:30 A.M. instead of 7:00 A.M., or whether it's okay to feed bread to birds, or how birds rediscover your feeders so quickly when you've just filled them after a long vacation.

    They did such a good job that, by 1926, no gray wolf packs were left in the park. Over the following decades, virtually every other part of the park's ecosystem was affected by the loss of the wolves --- from the animals who were their prey, to the plants that were the food for that prey, to the streams that were sheltered by those plants --- and the landscape was in distress. So, starting in 1995, in an attempt to reverse course, the government reintroduced gray wolves to the park. Over time, animal populations stabilized, waterways were restored and a healthy ecosystem was recreated across the land. It's a striking transformation, and a fascinating tale of life's complicated interdependencies.Jude Isabella's thoroughly researched, expert-reviewed text and Kim Smith's beautiful nature art bring science to life in this captivating story of renewal. Readers will recognize just how complex an ecosystem is and learn about the surprising interconnectedness of its members. Biodiversity, ecosystems, the food chain, habitats, needs of living things and the importance of human stewardship of the environment are all covered through this real-life example, offering direct links to earth and life science curriculums. Food web infographics help reinforce the information. A glossary and index add to the book's usefulness.

    The planet is full of millions of species of plants, birds, animals, and microbes, and every single one -- including us -- is part of a big, beautiful, complicated pattern. When humans interfere with parts of the pattern, by polluting the air and oceans, taking too much from the sea, and cutting down too many forests, animals and plants begin to disappear. What sort of world would it be if it went from having many types of living things to having just one? In a beautiful follow-up, the creators of the award-winning Tiny Creatures: The World of Microbes deliver an inspiring look at the extraordinary diversity of Earth's inhabitants -- and the importance of their preservation.
