American Alligator

https://kids.nationalgeographic.com/animals/reptiles/facts/american-alligator

American alligators once faced extinction. The United States Fish and Wildlife Service placed them on the endangered species list in 1967. Fortunately, the legal protection worked. Just 20 years later, American alligators were taken off the list. Brought back from the brink of extinction, over a million of these reptiles survive today. Now the main threat to alligators is habitat destruction, caused by such human activities as draining and developing wetlands. American alligators live in the wild in the southeastern United States. You’re most likely to spot them in Florida and Louisiana, where they live in rivers, lakes, ponds, swamps, bayous, and marshes. These reptiles are kind of clumsy on land, but they’re built for life in the water. Great swimmers, they are equipped with webbed feet and strong tails that propel them through the water. An average male American alligator is 10 to 15 feet (three to five meters) long. Half of its length is its massive, strong tail. An alligator can weigh as much as half a ton (1,000 pounds), but an average male weighs between 500 and 600 pounds (227 to 272 kilograms). Females are usually smaller than males. As big and ferocious as the female alligator may look, she is a gentle mother. A mother alligator makes a nest on shore, where she lays her eggs. Then she guards her eggs until they’re ready to hatch. At that point the babies start to make noises, and their mother hears her little ones‘ peeps as they break out of the eggs. She gently carries them—in her mouth—to the water nearby. Newly hatched young are only about six to eight inches (15 to 20 centimeters) long, and very vulnerable. Their mother protects them from predators, which include raccoons, bobcats, birds, and even other alligators. The young alligators stay with their mother for up to two years. After that, they’re able to fend for themselves.

Pig

https://kids.nationalgeographic.com/animals/mammals/facts/pig

Despite their reputation, pigs are not dirty animals. They’re actually quite clean. The pig’s reputation as a filthy animal comes from its habit of rolling in mud to cool off. Pigs that live in cool, covered environments stay very clean. Pigs are also known as hogs or swine. Male pigs of any age are called boars; female pigs are called sows. Pigs are found and raised all over the world, and provide valuable products to humans, including pork, lard, leather, glue, fertilizer, and a variety of medicines. Most pigs raised in the United States are classified as meat-type pigs, as they produce more lean meat than lard, a fat used in cooking. In the wild, pigs eat everything from leaves, roots, and fruit to rodents and small reptiles. In the United States, farm-raised pigs eat commercially made diets of mostly corn. In Europe, pigs eat barley-based diets. Pigs have sharp tusks that help them dig and fight. Farmers often take off the tusks to avoid injury to people and other pigs. Sows give birth to a litter of young called piglets. They usually nurse the piglets for three to five weeks. Piglets weaned off their mother’s milk are not called piglets but are referred to as shoats. Piglets weigh about 2.5 pounds (1.1 kilograms) at birth, and usually double their weight in one week. Fully grown, pigs can grow to between 300 and 700 pounds (140 and 300 kilograms), and sometimes much more. Pigs have poor eyesight, but a great sense of smell. The pig’s nostrils are on its leathery snout, which is very sensitive to touch. The pig uses the snout to search, or root, for food. Pigs are among the smartest of all domesticated animals and are even smarter than dogs.

Mountain Gorilla

https://kids.nationalgeographic.com/animals/mammals/facts/mountain-gorilla

Youngsters tumble, climb, and run playing follow the leader. Another group plays a rowdy game of king of the mountain. Several adults watch the action, relaxing nearby. Is this a playground scene at school? No, guess again. It’s a lush mountain forest high in the Virunga mountains of Africa, and the playmates are young mountain gorillas under the watchful eyes of their mothers. For a long time the image most people had of a gorilla encounter included chest pounding, roaring, charging, and big, bared teeth. But researchers studying gorillas reveal a very different picture of mountain gorillas. The animals are peaceful, gentle, social, and mainly vegetarian creatures. The occasional ferocious-looking, impressive displays are generally from a male gorilla protecting his family group from a threat. A typical group is led by the biggest and strongest mature male gorilla—often the guy doing any chest pounding or charging. He’s called a silverback because the hair on a male’s back turns from black to silvery gray as he matures. This happens when he is between 11 and 13 years old. A silverback’s group normally includes a subadult male or two and a few females and their young. Mountain gorillas wander around a home range of up to 15 square miles (39 square kilometers). Mountain gorillas spend much of their time eating. Their food includes a variety of plants, along with a few insects and worms. At night the animals make a nest to sleep in. Many lightweight gorillas nest in trees, making beds of bent branches. The heavier individuals may nest in grasses on the ground. Babies snuggle with their mothers for the night. Life for mountain gorillas isn’t all peaceful. They are endangered, threatened by civil war in a small area of Africa where they live. Hunters kill them for food or trophies. Their forests are chopped down for farmland, fuel, and housing. But many dedicated scientists, park rangers, and other concerned people are working hard to protect mountain gorillas, their forests, and their way of life in the mountains.

Snowy Owl

https://kids.nationalgeographic.com/animals/birds/facts/snowy-owl

When you see a snowy owl, it’s clear how the bird probably got its name: they’re snow-white. Males are generally whiter than females. As males grow older, they get whiter. The females never become completely white—remaining brownish with darker markings. These large owls mainly live in the Arctic in open, treeless areas called tundra. Snowy owls perch on the ground or on short posts. From there they patiently watch for prey. Their favorite target is lemmings—small mouselike rodents—but they also hunt for other small rodents, rabbits, birds, and fish. Snowy owls have excellent eyesight, but they obviously can’t see their prey when it’s underneath snow or a thick layer of plants. To capture those meals, the owl relies on its other keen sense: hearing. In flight, snowy owls generally cruise low to the ground. Once they spot their prey, they approach it from the air, and snatch it up using the large, sharp talons, or claws, on their feet. Most owls sleep during the day and hunt at night, but the snowy owl is active during the day, especially in the summertime. They tend to be most active at dawn and dusk. Snowy owl pairs usually mate for life. Female snowy owls lay from 3 to 11 eggs at a time, in a nest built on the ground. When there is plenty of food available, snowy owls tend to lay more eggs than when food is scarce. Lemmings make up the main part of the snowy owls‘ diet, and lemming population numbers rise and fall naturally. Sometimes, if there is not enough prey around to feed baby owls, the adult pair won’t lay any eggs at all until the supply of food improves. The female snowy owl sits on her eggs until they hatch. The male feeds her while she keeps their eggs warm and safe. After about one month, the eggs hatch. Babies are covered in soft white down when they hatch. As new feathers replace the down, the birds become light brown. The young leave the nest less than a month after they hatch. By the time they’re about a month and a half old, the young owls can fly well, but their parents take care of them for another ten weeks or more.
