Flamingos are famous for their bright pink feathers, stilt-like legs, and S-shaped neck. When a flamingo spots potential dinner—favorite foods include shrimp, snails, and plantlike water organisms called algae—it plunges its head into the water, twists it upside down, and scoops the fish using its upper beak like a shovel. They are able to „run“ on water, thanks to their webbed feet, to gain speed before lifting up into the sky. Flamingos build nests that look like mounds of mud along waterways. At the top of the mound, in a shallow hole, the female lays one egg. The parents take turns sitting on the egg to keep it warm. After about 30 days, the egg hatches. Flamingo young are born white, with soft, downy feathers and a straight bill. The bill gradually curves downward as the flamingo matures. Both parents take care of the newborn flamingo, feeding it a fluid produced in their digestive systems. The young leave the nest after about five days to join other young flamingos in small groups, returning to the parents for food. The parents identify their chick by its voice. After about three weeks, the adults herd young flamingos into large groups called crèches where they start to look for food on their own. Most flamingo species are not endangered, although the Andean flamingo is listed as Vulnerable, and the Chilean, Lesser, and Puna flamingos are Near Threatened.

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.

This is one cat that doesn’t need any help getting down from a tree. The leopard is so comfortable up there that it often stalks prey and even hauls its kills up into the branches. Leopards are powerful big cats closely related to lions, tigers, and jaguars. They live in sub-Saharan Africa, northeast Africa, Central Asia, India, and China. However, many of their populations are endangered, especially outside of Africa. You can identify most leopards by their light color and distinctive dark spots. Those spots are called rosettes, because they resemble the shape of a rose. These patterns camouflage their bodies as they move through the grass and trees. Black leopards, which appear to be almost solid in color because their spots are hard to distinguish, are commonly called black panthers. Unlike lions, leopards are solitary creatures. Males are almost entirely solitary and females only break their solitude when they are raising cubs. But, like lions, leopards roar. Male leopards defend their territory by roaring and scent marking, while females use their roar to attract mates and call their cubs. A leopard roar is a rough rasp, like a handsaw cutting wood. Leopard cubs are born with barely visible spots. The mother hides her cubs and moves them from one safe location to the next until they are old enough to begin playing and learning to hunt. When the cubs are about two years old, they live on their own. But the maternal bonds are strong, and offspring sometimes have reunions with their mothers.

There are more than 200 species of squirrels living all around the world, including kinds of tree, ground, and flying squirrels. You may have seen the eastern gray squirrel in parks, your backyard, or in a forest in the eastern half of the United States. Eastern gray squirrels forage for nuts, seeds, buds, and flowers of trees. Like other tree squirrels, the eastern gray squirrel plays an important role in what’s known as seed dispersal. As winter approaches, squirrels carry their food and bury it in several locations. They hide more food than they will recover or eat. The buried seeds and nuts sprout and begin to grow in these locations the following spring. Eastern gray squirrels have an excellent sense of smell, which they use to help locate food that they’ve hidden away. They can also pick up information about their fellow squirrels by smelling them. They communicate with each other by making sounds and body movements, such as tail flicking. When predators such as red foxes and red-tailed hawks are nearby, eastern gray squirrels will sound warning calls to alert other squirrels. Female eastern gray squirrels may start having babies at as young as five and a half months old. Females can have litters twice a year, each usually consisting of two to four babies. They gather leaves and twigs and build nests high in the trees to house their young offspring, or use tree cavities as dens. Newborn eastern gray squirrels don’t have fur when they are born and are not able to see. They often weigh as little as half an ounce (14 grams). They leave the nest by around ten to twelve weeks old and they become fully grown by around nine months.

Mallard ducks are the most common and recognizable wild ducks in the Northern Hemisphere. You’ll find them near ponds, marshes, streams, and lakes, where they feed on plants, invertebrates, fish, and insects. Mallards are dabbling, or surface-feeding, ducks because they eat by tipping underwater for food—head down, feet and tail in the air—rather than diving. Mallards also forage and graze for food on land. The male mallard duck, called a drake, sports a glossy green head, a white ring around its neck and a rich, chestnut-brown breast. The mottled brown female mallard looks downright dull next to the male’s showy feathers. The mallard duck’s outer feathers are waterproof, thanks to oil that’s secreted from a gland near the tail. Beneath this tightly packed waterproof layer of feathers lies a soft, warm layer of feathers called down. Twice a year, mallards molt, or shed, their flight feathers, temporarily grounding the birds for several weeks until the feathers grow back. Mallards fly in groups called flocks. Like most migratory birds, mallards fly in the famous V formation. During winter migration, mallards fly south in search of warm weather, often resting at the same spots year after year. Migrating mallards can travel great distances, relying on rivers, coasts, and valleys to find their way. A female mallard lays up to a dozen eggs in nests on the ground near water, often in a small depression or tree hole. She lines the nest with warm down plucked from her undercoat. Soon after birth, baby ducks, called ducklings, open their eyes. A little more than a day after hatching, ducklings can run, swim, and forage for food on their own. They stay in the nest for less than a month. A group of ducklings is called a brood. Outside the nest, the brood sticks close by the mother for safety, often following behind her in a neat, single-file line.

Fastest mammal on land, the cheetah can reach speeds of 60 or perhaps even 70 miles (97 or 113 kilometers) an hour over short distances. It usually chases its prey at only about half that speed, however. After a chase, a cheetah needs half an hour to catch its breath before it can eat. The cheetah’s excellent eyesight helps it find prey during the day. The cheetah is hard to see because its spotted coat blends with the tall, dry grass of the plains. Suddenly, the cheetah makes a lightning dash. It knocks its prey to the ground and then bites its throat. Once found throughout Asia and Africa, cheetahs today are racing toward extinction. Loss of habitat and declining numbers of their prey combine to threaten the future of these cats. Cheetahs live and hunt mainly in open grasslands and bushy areas in parts of Africa and the Middle East. Cheetahs eat small- to medium-size animals, such as hares, impalas, wildebeest calves, and gazelles. Because of their size, strength, and predatory skills, cheetahs are considered one of the “big cats.” Tigers, lions, leopards, jaguars, and cougars are also part of this grouping. Take the big cat quiz to see how much you know about these fierce felines. Then, just for fun, see which wild cat you’re most like with our personality quiz.

Female black widows are shiny black, with a red-orange hourglass pattern on their abdomen. Male black widows are not black, but brown or gray with small red spots. Black widows are poisonous arachnids—animals that have a skeleton outside their body, a segmented body, and eight jointed legs. They are not insects. Their deadly poison is said to be 15 times stronger than rattlesnake venom. Black widows use a silk-like substance to weave tangled-looking webs, typically close to the ground in covered or dark places, such as near drain pipes or under logs. The female hangs upside down in the web to await her prey, exposing her bright markings as a warning to potential predators. The black widow senses vibrations to the web. When an unlucky intruder gets trapped, the spider immediately begins weaving its glue-like webbing around it. Insects such as flies, mosquitoes, or even larger prey like grasshoppers are typically caught. Once captured, the black widow injects its victims with poison, paralyzing them. The tips of the black widow’s legs are coated with an oily substance that prevents the black widow from getting caught in its own web. Adult male and female black widows live solitary lives, meeting only to breed. The female black widow lays approximately 200 eggs. The eggs incubate for some 20 days in a small, round papery sac that’s attached to the mother’s web. After hatching, the baby spiders stay in the cocoon for up to one month. Three species of poisonous North American spiders carry the common name black widow under the genus Latrodectus. Each species occupies a distinct region of North America, as their names suggest: Eastern black widows (L. mactans), northern black widows (L. variolus), and western black widows (L. hesperus). These three species have very similar physical and behavioral characteristics. The name “black widow” comes from the female’s habit of eating the male after mating.

 The female black widow is approximately 1.5 inches (38 millimeters) long. The male is about half the female’s size.

 The black widow is prey for birds and other spiders. Although poisonous, the black widow is not considered aggressive unless threatened. In fact, the male black widow is reclusive and hardly ever seen by humans. While the black widow’s poison is rarely fatal to humans, it can cause severe pain and nausea.

It’s a quiet, warm summer evening with no human in sight for miles in the woods. As the sun sets, tiny flashes of light start to flicker throughout the trees. At first there’s just a few, but soon hundreds of blinking lights are floating in the forest. Fireflies have come out for the evening.

The mountain lion goes by many names, including cougar, catamount, panther, red tiger, deer tiger, and puma. This cat can be found throughout much of South and North America. The mountain lion used to be found all over the United States, but now is primarily seen in the western U.S. An endangered subspecies of mountain lion also remains in Florida. These felines are comfortable in many different habitats and, aside from humans, have the widest geographic range of any land mammal in the Western Hemisphere. In North America, mountain lions eat mainly deer, but they also eat smaller animals, such as mice and rabbits. These cats have a poor sense of smell, but have excellent vision and hearing that help them hunt in the early morning and evening hours. Their powerful hind legs enable them to jump as far as 40 to 45 feet (12 to 13 meters). This carnivore stalks its prey until an opportunity arises to pounce. Mountain lions “cache” their prey, or hide it under leaves and soil, where they can come back and feed on it over the course of several days. Mountain lions don’t roar, but females have a loud scream, which is believed to attract males. Females have an average of two to four cubs per litter and give birth in a den. The cubs are born with spots, which usually disappear by the time they are roughly nine months old. Their eyes also change from blue to yellow by the time they reach 16 months old. By 18 months, the young cats leave their mom to go fend for themselves. Because of their size, strength, and predatory skills, mountain lions are considered one of the “big cats.” Tigers, leopards, cheetahs, and jaguars are also part of this grouping.
