    Here is the incredible story of Elizabeth, a real-life elephant seal who made her home in the Avon River in the city of Christchurch, New Zealand. When Elizabeth decides to stretch out across a two-lane road, the citizens worry she might get hurt or cause traffic accidents, so a group of volunteers tows her out to sea. But Elizabeth swims all the way back to Christchurch. The volunteers catch her again and again—each time towing her farther, even hundreds of miles away—but, still, Elizabeth finds her way back home. Includes back matter with information about elephant seals.From the Hardcover edition.

    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.

    Because she was going to study him, she decided to call him Alex--short for Avian Learning EXperiment. At that time, most scientists thought that the bigger the brain, the smarter the creature; they studied great apes and dolphins. African greys, with their walnut-sized "birdbrains," were pretty much ignored--until Alex. His intelligence surprised everyone, including Irene. He learned to count, add, and subtract; to recognize shapes, sizes, and colors; and to speak, and understand, hundreds of words. These were things no other animal could do. Alex wasn't supposed to have the brainpower to do them, either. But he did them anyway.Accompanied by Meilo So's stunning illustrations, Alex and Irene's story is one of groundbreaking discoveries about animal intelligence, hard work, and the loving bonds of a unique friendship.

His friends and colleagues have included George and Joy Adamson and David Attenborough; he showed Dian Fossey her first mountain gorilla. His wife and long-term collaborator was Joan Root, who was tragically murdered in 2006 in retaliation for her environmental campaigning in Kenya. In "Ivory, Apes & Peacocks," Alan tells the story of his life's work, from his arrival in Kenya as a young boy (furious at having to leave behind Britain's birds) to his game-changing films, which looked at whole ecosystems (baobab trees, termite mounds) rather than the Big Five animals. Along the way we encounter Sally the pet hippo and Emily the house-proud chimp as well leopard and snake bites, ballooning adventures and amphibious cars. In this extraordinary memoir we look at Africa's wonders through the eyes of a visionary, live through hair-raising adventure and personal tragedy and also bear witness to a natural world now largely lost from view.
