Some birds are fantastically colorful and some are plain. But what do all birds share? Early nonfiction expert Lizzy Rockwell explains that birds have beaks, wings, and feathers, and hatch from eggs. Other animals might have some of these features in common, but only a bird has them all.Only a bird is a bird!A clear text and beautiful illustrations cover dozens of different birds and their shared characteristics, as well as the unique qualities of unusual birds, such as penguins and peacocks.

    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.

    But there was a time when people hunted the otters almost to extinction. Without sea otters to eat them, an army of hungry sea urchins grew and destroyed entire kelp forests. Fish and other animals that depended on the kelp were lost, too. But when people protected the sea otters with new laws, their numbers began to recover, and so did the kelp forests. Susannah Buhrman-Deever offers a beautifully written account of a trophic cascade, which happens when the removal of a single element affects an entire habitat. Asides that dig deeper are woven throughout Matthew Trueman’s dynamic illustrations, starring a raft of charismatic sea otters. Back matter includes more information about sea otters and kelp forests, including their importance and current status, the effects of the international fur trade on indigenous peoples, and a list of books and websites for readers who wish to continue to explore.

    Following the story of marine biologist and animal advocate at the Humane Society of the US, Naomi Rose, Kirby tells the gripping story of the two-decade fight against PR-savvy SeaWorld, which came to a head with the tragic death of trainer Dawn Brancheau in 2010. Kirby puts that horrific animal-on-human attack in context. Brancheau’s death was the most publicized among several brutal attacks that have occurred at Sea World and other marine mammal theme parks. Death at SeaWorld introduces real people taking part in this debate, from former trainers turned animal rights activists to the men and women that champion SeaWorld and the captivity of whales. In section two the orcas act out. And as the story progresses and orca attacks on trainers become increasingly violent, the warnings of Naomi Rose and other scientists fall on deaf ears, only to be realized with the death of Dawn Brancheau. Finally he covers the media backlash, the eyewitnesses who come forward to challenge SeaWorld’s glossy image, and the groundbreaking OSHA case that challenges the very idea of keeping killer whales in captivity and may spell the end of having trainers in the water with the ocean’s top predators.

    But what if we took these big, hard-to-imagine objects and events and compared them to things we can see, feel and touch? Instantly, we'd see our world in a whole new way." So begins this endlessly intriguing guide to better understanding all those really big ideas and numbers children come across on a regular basis. Author David J. Smith has found clever devices to scale down everything from time lines (the history of Earth compressed into one year), to quantities (all the wealth in the world divided into one hundred coins), to size differences (the planets shown as different types of balls). Accompanying each description is a kid-friendly drawing by illustrator Steve Adams that visually reinforces the concept. By simply reducing everything to human scale, Smith has made the incomprehensible easier to grasp, and therefore more meaningful. The children who just love these kinds of fact-filled, knock-your-socks-off books will want to read this one from cover to cover. It will find the most use, however, as an excellent classroom reference that can be reached for again and again when studying scale and measurement in math, and also for any number of applications in social studies, science and language arts. For those who want to delve a little deeper, Smith has included six suggestions for classroom projects. There is also a full page of resource information at the back of the book.
