But have you ever heard of a butterfly farm? How do you raise a butterfly? On a farm in Costa Rica, workers care for these delicate, winged creatures as they change from eggs to caterpillars to pupae. Like any other crop, the butterflies will eventually leave the farm. But where will they go? And just how do you ship a butterfly? Very carefully! To discover how it works, follow these butterflies on a remarkable journey!

    Frogs are astonishing in their variety and crucial to ecosystems. Onomatopoeic text and stunning illustrations introduce young readers to these fascinating and important creatures, from Chile to Nepal to Australia.

    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.

    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.

    And how animals lay, protect, and even use each other's eggs as a food source help reveal the life cycle of the natural world. Eggs come in all shapes and sizes. The ostrich’s is the largest, but some are so small, you need a microscope to spot them. Animals hide them and disguise them in smart and surprising ways, too. Some abandon their eggs, while others protect them fiercely and carry them wherever they go. There are as many kinds of eggs as there are animals that depend on them, because in the animal kingdom, the fight for survival begins with the simple, but extraordinary, egg.

    It’s time. Today is the day he will once again cast himself into the air, spiral upward into the clouds, and bank into the wind.He wears a black band on his lower right leg and an orange flag on his upper left, bearing the laser inscription B95. Scientists call him the Moonbird because, in the course of his astoundingly long lifetime, this gritty, four-ounce marathoner has flown the distance to the moon—and halfway back! B95 is a robin-sized shorebird, a red knot of the subspecies rufa. Each February he joins a flock that lifts off from Tierra del Fuego, headed for breeding grounds in the Canadian Arctic, nine thousand miles away.  Late in the summer, he begins the return journey. B95 can fly for days without eating or sleeping, but eventually he must descend to refuel and rest. However, recent changes at ancient refueling stations along his migratory circuit—changes caused mostly by human activity—have reduced the food available and made it harder for the birds to reach. And so, since 1995, when B95 was first captured and banded, the worldwide rufa population has collapsed by nearly 80 percent. Most perish somewhere along the great hemispheric circuit, but the Moonbird wings on. He has been seen as recently as November 2011, which makes him nearly twenty years old. Shaking their heads, scientists ask themselves: How can this one bird make it year after year when so many others fall?  National Book Award–winning author Phillip Hoose takes us around the hemisphere with the world’s most celebrated shorebird, showing the obstacles rufa red knots face, introducing a worldwide team of scientists and conservationists trying to save them, and offering insights about what we can do to help shorebirds before it’s too late. Through prose, research, and images, Hoose explores the tragedy of extinction through the triumph of a single bird.

    A fluffy, sparkly, princess-y color. But it's so much more. Sure, pink is the color of princesses and bubblegum, but it's also the color of monster slugs and poisonous insects. Not to mention ultra-intelligent dolphins, naked mole rats and bizarre, bloated blobfish. Isn't it about time to rethink pink? Slip on your rose-colored glasses and take a walk on the wild side with zoologist Jess Keating, author of How to Outrun a Crocodile When Your Shoes Are Untied, and cartoonist David DeGrand. A New York Public Library Best Book for Kids, 2016 "The 2016 Ambassador to Young People's Science and Nature books is unquestionably the blobfish." --Shelftalker "Readers will never look at pink the same way." --Publishers Weekly

    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.

    Why do crows have this ability? What does the crow know and what does it tell us about brain size, the evolution of intelligence, and just who is the smartest creature on the planet? In the latest addition to the Scientists in the Field series, the creators of The Frog Scientist take us to a beautiful Pacific island, where a lively cast of both crows and scientists is waiting to amuse and enlighten us.

    Using sunlight, landmarks, and scents to remember the path, she goes in search of pollen and nectar to share with the thousands of other bees in her hive.

(Because its wings mutated and hardened). How did the gecko survive 160 million years? (By becoming nocturnal and developing sticky toe pads.) How did the shark and the crow and the tiny ant survive millions and millions of years? When 99 percent of all life forms on earth have become extinct, why do some survive? And survive not just in one place, but in many places: in deserts, in ice, in lakes and puddles, inside houses and forest and farmland? Just how do they become ubiquitous?
