    They're also the national symbol of Panama. But they started to disappear about fifteen years ago. What's killing them? Could it be a change in their habitat? What about pollution? Might it be a result of climate change? Follow a team of scientists working to save these frogs and protect frog populations worldwide in this real-life science mystery.

    In this visually driven volume, kids come face-to-face with some head-to-toe boney comparisons, many of them shown at actual size. Here you'll find the differences between a man's hand and that of a spider monkey; the great weight of an elephant's leg, paired with the feather-light femur of a stork; and rib-tickling info about snakes and sloths. How many bones are in the whole human body?

    All around the world -- in the sea, in the soil, in the air, and in your body -- there are living things so tiny that millions could fit on an ant's antenna. They're busy doing all sorts of things, from giving you a cold and making yogurt to eroding mountains and helping to make the air we breathe. If you could see them with your eye, you'd find that they all look different, and that they're really good at changing things into something else and at making many more microbes like themselves! From Nicola Davies comes a first exploration for young readers of the world's tiniest living organisms.

    From tiny bee hummingbird nests to orangutan nests high in the rainforest canopy, an incredible variety of nests are showcased here in all their splendor.

    The prairie and desert grasslands were home to a variety of animals, from small prairie dogs to huge bison. But in the nineteenth century, ranching and farming took hold in the grasslands, and over time many of the animals and plants vanished.Then, in the late 1980s, scientists discovered a region in Mexico where green and gold grasses still waved and prairie dogs still barked. The scientists understood the importance of this grassland ecosystem and the prairie dogs' key role in it. Could they now preserve the area and bring back its lost animals and plants?This moving nonfiction tale of environmental recovery builds on the success of the acclaimed Parrots Over Puerto Rico and The Mangrove Tree. Cumulative song text plus prose passages combine to celebrate North America s grasslands, their iconic prairie dogs, and the dedicated scientists who work to make the grasslands healthy again. Comprehensive backmatter makes this book perfect for classroom use, with text that hits both Science and Social Studies Common Core Standards. Teacher s Guide available at leeandlow.com."

    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.

    A concise main text highlights how feathers are not just for flying. More curious readers are invited to explore informative sidebars, which underscore specific ways each bird uses its feathers for a variety of practical purposes. A scrapbook design showcases life-size feather illustrations.

    A number of different species and spider behaviors are highlighted in this book, accompanied by clear, labeled illustrations and important vocabulary.This new and updated edition, vetted by an entomologist, includes revised illustrations and the latest in arachnid science. Filled with interesting trivia and information on the history of spiders, as well as an explanation of the difference between spiders and insects, this is a great introduction that takes the fear out of our eight-legged, web-spinning friends.

    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.

    In this fun and fascinating nonfiction picture book, join world-renowned photographers and biologists on their close encounters with the curious creatures that make their own light. Author’s note and bibliography included.

    At the Cheetah Conservation Fund's (CCF) African headquarters in Namibia, Laurie Marker and her team save these stunning, swift, and slender creatures from extinction. Since the organization's start in 1990, they've rescued more than 900 cheetahs, most of whom have been returned to the wild.     But this arduous challenge continues. For most African livestock farmers, cheetahs are the last thing they want to see on their properties. In the 1980s, as many as 19 cheetahs per farmer died each year. Cheetahs were considered vermin--but, in learning more about this magnificent species, we know this is far from true.     Today, CCF acts as a liaison between the farmers and the cheetahs, in order to promote cohabitation in an ecosystem that cannot thrive without the existence of the precious and predatory cheetah. On a wild ride through the African wilderness--sometimes sniffing out scents left in the dirt--Sy Montgomery and Nic Bishop join CCF in studying the cheetah's ecological, genetic, and behavioral patterns in order to chase down the fastest animal on land and save the species--before it is too late.

    Giraffes have eyelashes. Sloths hang from trees for days at a time without going to the bathroom. These are just some of the insights featured in Life-Size Zoo. Acclaimed wildlife photographer Toyofumi Fukuda visited Japan's premier zoos to capture remarkably vivid and detailed close-up photographs of 21 animals, from pandas and meerkats to giraffes, rhinos, and elephants (adult and baby). Each photograph is accompanied by a profile including body length, weight, and natural habitat, as well as fun facts about the animal.

    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.

    But these and many other animals are in danger of disappearing altogether, joining the dodo, the marsupial wolf, the great auk, and countless other animals we will never see again. Using the experiences of a few endangered species as examples, Martin Jenkins highlights the ways human behavior can either threaten or conserve the amazing animals that share our planet. Vicky White’s stunning portraits of rare creatures offer a glimpse of nature’s grace and beauty — and give us a powerful reason to preserve it.
