Emperor penguins spend their entire lives on Antarctic ice and in its waters. They survive—breeding, raising young, and eating—by relying on a number of clever adaptations. These flightless birds breed in the winter. After a courtship of several weeks, a female emperor penguin lays one single egg then leaves! Each penguin egg’s father balances it on his feet and covers it with his brood pouch, a very warm layer of feathered skin designed to keep the egg cozy. There the males stand, for about 65 days, through icy temperatures, cruel winds, and blinding storms. Finally, after about two months, the females return from the sea, bringing food they regurgitate, or bring up, to feed the now hatched chicks. The males eagerly leave for their own fishing session at sea, and the mothers take over care of the chicks for a while. As the young penguins grow, adults leave them in groups of chicks called crèches while they leave to fish. There is a reason for the timing of emperor penguins‘ hatching. By December, when the Antarctic weather has warmed somewhat, the ice the penguins occupy begins to break up, bringing open waters closer to the nesting sites. Now the chicks are old enough to take to the seas and fish for their own food. Check out the book Penguins vs. Puffins for more about these amazing birds! Watch a YouTube playlist all about penguins.

Giraffes grow about 4 feet (1.2 meters) in their first year of life. A newborn giraffe is about 6 feet (1.9 meters) tall at birth and weighs about 150 pounds (68 kilograms). Many young giraffes, called calves, die from lion attacks during their first year of life. Once a giraffe reaches adulthood its height is often enough to protect it from lions. Adult giraffes, however, must still be careful of lions when they are bending down to drink water or rest. Usually giraffes will drink or rest in shifts so that at least one giraffe is always on the lookout for approaching predators. The giraffes‘ height and excellent vision give them a wide view of the grasslands where they live, making it easy to spot predators from a distance. Some scientists believe that other animals—such as zebras, antelope, and wildebeests—often congregate near giraffes to take advantage of their ability to see danger from a distance. The giraffe could be considered the early warning system of the African grasslands.

Snowy white tundra swans breed in the Arctic. Young swans have fluffy gray feathers in their first winter. The tundra swan call is higher and more like that of a Canada goose. Tundra swans mate for life and pair up for nearly a year before breeding. They breed in solitary pairs spread out across the Arctic tundra. They can be nasty protectors and are able to fend off predators like foxes. They prefer to nest near wetlands containing pondweed. They line their large, stick nests with moss and grasses. Females lay about four eggs and incubate them for 32 days. These large birds feed by dipping their heads underwater to pluck aquatic plants, roots, and tubers. Their diet consists of mainly submerged plants and roots, but they will also eat some cereal grains, corn, and mollusks, which are a kind of shellfish. The majestic tundra swan is a strong swimmer and can take off from the water with a running start and beat their wings until airborne. Their flapping wings produce a sound that earned them the name „whistling swan.“ They migrate thousands of miles to enjoy a milder winter in North America’s Atlantic and Pacific coastlines, bays, and lakes. Twice a year, they fly 3,725 miles (6,000 kilometers) round-trip between the breeding and wintering locations.

Rattlesnakes live in many places and habitats in the Western Hemisphere, from mountains to deserts and plains. There are more than 24 rattlesnake species and all of them have that most-famous feature: the rattle! The rattle is found at the tip of the rattlesnake’s tail. The snake uses the rattle to warn potential aggressors to back off or to distract prey. The famous rattle noise comes from the sound created when hollow and bony doughnutlike segments in the rattle bang together. As rattlesnakes age, segments on the end of the rattle wear out and break off. New segments grow when the rattlesnake sheds its skin, or molts. Like other snakes, rattlesnakes don’t have ears and can’t hear most sounds. They detect movement by sensing vibrations in the ground. Their eyes see well even in low light. The rattlesnake’s triangular head contains a hollow spot between the eyes and nostrils called a pit. This pit is actually a sensory organ that helps the rattlesnake hunt in darkness by detecting body heat.

Duck-billed platypuses are small, shy animals. They have a flattened head and body to help them glide through the water. Their fur, dark brown on top and tan on their bellies, is thick and repels water to keep them warm and dry even after hours of swimming. Their head and body grow to about 15 inches (38 centimeters) and their tail about 5 inches long (13 centimeters). Their most remarkable feature is their amazing snout. It looks like a duck’s bill, but is actually quite soft and covered with thousands of receptors that help the platypus detect prey. Males are also venomous. They have sharp stingers on the heels of their rear feet and can use them to deliver a strong toxic blow to any foe. Platypuses spend most of their time alone, sleeping or eating. These mammals are bottom feeders. They scoop up insects and larvae, shellfish, and worms in their bill along with bits of gravel and mud from the bottom. All this material is stored in cheek pouches and, at the surface, mashed for consumption. Platypuses do not have teeth, so the bits of gravel help them to „chew“ their meal. Platypuses are long-lived, surviving 20 years or more in captivity and up to 12 years in the wild. Scientists think these fascinating creatures are the earliest relatives of modern mammals. Recent studies show that they first evolved more than 112 million years ago, well before the extinction of the dinosaurs.

Slowly stalking down the snowy hillside, the Amur leopard watches its prey through the trees. In the clearing below, a sika deer munches on tree bark, one of its few remaining food sources during the cold Russian winter. The leopard crouches, its body so low to the ground that its belly fur brushes the snow. Suddenly it bounds and springs forward, tackling the deer from 10 feet away. It’s dinnertime.

Swoosh! A peregrine falcon can dive up to 200 miles (323 kilometers) an hour to capture prey in flight, striking in midair with its outstretched talons, or claws. Peregrines usually hunt with either a swift chase or a fast dive. Starlings, pigeons, and doves are among their favorite meals. A common bird of prey (a group of hunting birds that includes such birds as hawks and eagles), the peregrine is an adaptable falcon that can be found in almost any habitat. Peregrines live from cold tundra to hot deserts, from sea level to high in the mountains. Their adaptability even allows them to thrive in cities. They live in a greater variety of habitats than almost any other bird of prey. Some peregrine falcons migrate in the winter from their nesting grounds in the Arctic all the way to South America—a round-trip distance of up to 15,500 miles (24,945 kilometers). They make the return trip north when it’s time to mate and lay eggs. Peregrines don’t build nests. They usually just find a shallow dip in some rocks or scrape a depression in the soil on the ledge of a cliff, or even use the ledge of a building. Female peregrines lay two to four eggs at a time. Parents incubate the eggs for about a month until the eggs hatch. Peregrine chicks stay in the nest for up to six weeks, by which time they’ve learned to fly. Peregrine falcons in the United States were listed as an endangered species after their numbers dropped dangerously low between the 1950s and the 1970s. Certain pesticides used by farmers—including DDT—harmed the peregrines by causing their eggshells to be dangerously thin—so fragile that they broke when the parents tried to incubate them. Laws were enacted to ban DDT and, fortunately the ban, along with other conservation efforts, led to the recovery of the species. In fact, scientists think there now may be more peregrines in some parts of their range than there ever used to be!
