    Since then, animals have evolved an amazing variety of eyes, along with often surprising ways to use them.

    Each fall, while the city's inhabitants dine on steaks, salads, and sandwiches, the great white sharks return to California's Farallon Islands to hunt their favorite meal: the seals that live on the island's rocky coasts. Massive, fast, and perfectly adapted to hunting after 11 million years of evolution, the great whites are among the planet's most fearsome, fascinating, and least understood animals. In the fall of 2012, Katherine Roy visited the Farallons with the scientists who study the islands' shark population. She witnessed seal attacks, observed sharks being tagged in the wild, and got an up close look at the dramatic Farallons—a wildlife refuge that is strictly off-limits to all but the scientsts who work there. Neighborhood Sharks is an intimate portrait of the life cycle, biology, and habitat of the great white shark, based on the latest research and an up-close visit with these amazing animals.

    Bugs, of all kinds, were considered to be “born of mud” and to be “beasts of the devil.”  Why would anyone, let alone a girl, want to study and observe them? One of the first naturalists to observe live insects directly, Maria Sibylla Merian was also one of the first to document the metamorphosis of the butterfly. In this nonfiction biography, illustrated throughout with full-color original paintings by Merian herself, author Joyce Sidman paints her own picture of one of the first female entomologists and a woman who flouted convention in the pursuit of knowledge and her passion for insects.

    But by 1844, not a single one of these magnificent birds was alive.In this stunningly illustrated non-fiction picture book, award-winning author and illustrator Jan Thornhill tells the tragic story of these birds that “weighed as much as a sack of potatoes and stood as tall as a preteen’s waist.” Their demise came about in part because of their anatomy. They could swim swiftly underwater, but their small wings meant they couldn’t fly and their feet were so far back on their bodies, they couldn’t walk very well. Still the birds managed to escape their predators much of the time … until humans became seafarers.Great Auks were pursued first by Vikings, then by Inuit, Beothuk and finally European hunters. Their numbers rapidly dwindled. They became collectors’ items — their skins were stuffed for museums, to be displayed along with their beautiful eggs. (There are some amazing stories about these stuffed auks — one was stolen from a German museum during WWII by Russian soldiers; another was flown to Iceland and given a red-carpet welcome at the airport.)Although undeniably tragic, the final demise of the Great Auk led to the birth of the conservation movement. Laws were eventually passed to prevent the killing of birds during the nesting season, and similar laws were later extended to other wildlife species.
