A POLAR BEARS SUMMER

A dual effort helps many parents face the challenge of raising their young in a short growing season, before the hardship of winter arrives. Exhausted from his swim, the bear must regain his strength. The next day, a sea fog shrouds the island. The wallases sense that they're in danger. Using the fog as cover, the bear approaches the herd. The adults close ranks around their young, presenting a wall of blubber and hide. He tests the bear, but it stands firm. It appears that the world's largest lamb carnivore has met his match. There must be a chink in the armour somewhere. Not here. This female walrus is shielding her pup, if he can just prise her off. The bear's claws and teeth can't penetrate her thick hide. With the herd retreating to water, the bear must move quickly. Having failed with one, he heads straight for another. The chance of his first meal in months is slipping away. He seems increasingly desperate. It's now or never. He must avoid the stabbing tusks if he's to win. The flailing walrus is immensely powerful and drags the bear away from the shallows towards the safety of the herd. It slips from his grasp. And it's not just that fabulous fur the fox has got. They have incredible senses, particularly their hearing. Despite having these fairly small ears, this fox will be able to detect its prey with pinpoint accuracy, even when it's hidden underneath the snow. In the depths of the Canadian winter, a young arctic fox is searching for food. He's still a hunting novice. It's not easy when you can't see your prey. With his acute senses, he can hear a faint sound under the snow. Lemmings. To catch one, he uses a special pouncing technique known as mousing. He has to judge its exact distance as well as the depth of snow. To help them find the right spot, foxes actually align their pounds to the earth's magnetic field. An extraordinary skill. But mousing isn't always easy. Especially for a beginner. you
