Animal of the week fun!


A baby harp seal rests on the Arctic ice. Its mother can distinguish it from hundreds of others by scent alone.
Harp seals spend relatively little time on land and prefer to swim in the North Atlantic and Arctic Oceans. These sleek swimmers cruise the chilly waters and feed on fish and crustaceans. They can remain submerged for up to 15 minutes. Harp seals are sometimes called saddleback seals because of the dark, saddlelike marking on the back and sides of their light yellow or gray bodies.Both sexes return each year to breeding grounds in Newfoundland, the Greenland Sea, and the White Sea. On this turf males fight for their mates, battling with sharp teeth and powerful flippers.When the mating ends, females gather in groups to give birth. Young harp seals are born on the ice, and mothers identify their own offspring from the multitudes by their smell. The young seals are famous for their snowy white coats. This fluffy fur is highly valued and has drawn hunters to the Newfoundland breeding grounds for two centuries. During the past several decades these grounds have become the scene of a human conflict between sealers and outraged environmentalists and animal rights activists. Modern hunts are better regulated than in the past, but the harp seal remains perhaps the most commercially important seal, with hundreds of thousands killed each year.

Wild horses in Montana's Pryor Mountains run through a field of wildflowers.
Horses and humans have an ancient relationship. Asian nomads probably domesticated the first horses some 4,000 years ago, and the animals remained essential to many human societies until the advent of the engine. Horses still hold a place of honor in many cultures, often linked to heroic exploits in war.There is only one species of domestic horse, but around 400 different breeds that specialize in everything from pulling wagons to racing. All horses are grazers.While most horses are domestic, others remain wild. Feral horses are the descendents of once-tame animals that have run free for generations. Groups of such horses can be found in many places around the world. Free-roaming North American mustangs, for example, are the descendents of horses brought by Europeans more than 400 years ago.Wild horses generally gather in groups of 3 to 20 animals. A stallion (mature male) leads the group, which consists of mares (females) and young foals. When young males become colts, at around two years of age, the stallion drives them away. The colts then roam with other young males until they can gather their own band of females.The Przewalski's horse is the only truly wild horse whose ancestors were never domesticated. Ironically, this stocky, sturdy animal exists today only in captivity. The last wild Przewalski's horse was seen in Mongolia in 1968.

No animal has a more distinctive coat than the zebra. Each animal's stripes are as unique as fingerprints—no two are exactly alike—although each of the three species has its own general pattern.Why do zebras have stripes at all? Scientists aren't sure, but many theories center on their utility as some form of camouflage. The patterns may make it difficult for predators to identify a single animal from a running herd and distort distance at dawn and dusk. Or they may dissuade insects that recognize only large areas of single-colored fur or act as a kind of natural sunscreen. Because of their uniqueness, stripes may also help zebras recognize one another.Zebras are social animals that spend time in herds. They graze together, primarily on grass, and even groom one another.Plains (Burchell's) zebras are the most common species. They live in small family groups consisting of a male (stallion), several females, and their young. These units may combine with others to form awe-inspiring herds thousands of head strong, but family members will remain close within the herd.Zebras must be constantly wary of lions and hyenas. A herd has many eyes alert to danger. If an animal is attacked, its family will come to its defense, circling the wounded zebra and attempting to drive off predators.

Giraffes are the world's tallest mammals, thanks to their towering legs and long necks. A giraffe's legs alone are taller than many humans—about 6 feet (1.8 meters). These long legs allow giraffes to run as fast as 35 miles (56 kilometers) an hour over short distances and cruise comfortably at 10 miles (16 kilometers) an hour over longer distances.Typically, these fascinating animals roam the open grasslands in small groups of about half a dozen.Bulls sometimes battle one another by butting their long necks and heads. Such contests aren't usually dangerous and end when one animal submits and walks away.Giraffes use their height to good advantage and browse on leaves and buds in treetops that few other animals can reach (acacias are a favorite). Even the giraffe's tongue is long! The 21-inch (53-centimeter) tongue helps them pluck tasty morsels from branches. Giraffes eat most of the time and, like cows, regurgitate food and chew it as cud. A giraffe eats hundreds of pounds of leaves each week and must travel miles to find enough food.The giraffe's height also helps it to keep a sharp lookout for predators across the wide expanse of the African savanna.The giraffe's stature can be a disadvantage as well—it is difficult and dangerous for a giraffe to drink at a water hole. To do so they must spread their legs and bend down in an awkward position that makes them vulnerable to predators like Africa's big cats. Giraffes only need to drink once every several days; they get most of their water from the luscious plants they eat.Female giraffes give birth standing up. Their young endure a rather rude welcome into the world by falling more than 5 feet (1.5 meters) to the ground at birth. These infants can stand in half an hour and run with their mothers an incredible ten hours after birth.Giraffes have beautiful spotted coats. While no two individuals have exactly the same pattern, giraffes from the same area appear similar.

Animal of the week fun!


Tree squirrels, like this eastern gray squirrel, are seen in many parks, backyards, and forests throughout the world.
Squirrels are familiar to almost everyone. More than 200 squirrel species live all over the world, with the notable exception of Australia.

The tiniest squirrel is the aptly named African pygmy squirrel—only five inches (thirteen centimeters) long from nose to tail. Others reach sizes shocking to those who are only familiar with common tree squirrels. The Indian giant squirrel is three feet (almost a meter) long.

Like other rodents, squirrels have four front teeth that never stop growing so they don't wear down from the constant gnawing. Tree squirrels are the types most commonly recognized, often seen gracefully scampering and leaping from branch to branch. Other species are ground squirrels that live in burrow or tunnel systems, where some hibernate during the winter season.

Ground squirrels eat nuts, leaves, roots, seeds, and other plants. They also catch and eat small animals, such as insects and caterpillars. These small mammals must always be wary of predators because they are tasty morsels with few natural defenses, save flight. Sometimes groups of ground squirrels work together to warn each other of approaching danger with a whistling call.

Tree squirrels are commonly seen everywhere from woodlands to city parks. Though they are terrific climbers, these squirrels do come to the ground in search of fare such as nuts, acorns, berries, and flowers. They also eat bark, eggs, or baby birds. Tree sap is a delicacy to some species.

Flying squirrels are a third, adaptable type of squirrel. They live something like birds do, in nests or tree holes, and although they do not fly, they can really move across the sky. Flying squirrels glide, extending their arms and legs and coasting through the air from one tree to another. Flaps of skin connecting limbs to body provide a winglike surface. These gliding leaps can exceed 150 feet (46 meters). Flying squirrels eat nuts and fruit, but also catch insects and even baby birds.

Whether they dwell high in a tree or in an underground burrow, female squirrels typically give birth to two to eight offspring. Babies are blind and totally dependent on their mothers for two or three months. Mothers may have several litters in a year, so most squirrel populations are robust.
