Fit for the Wild

When the last summer rains have fallen in the Serengeti, 1.3 million blue wildebeest set out from the exhausted southern grasslands, pursuing fresh pastures and tropical rainfall in the north. Their 1600km annual journey is the most spectacular animal migration on earth.

Where the ocean meets the African continent, the Cape fur seal leads a double life, depending on both land and sea to feed, breed and survive. As spring arrives, the pregnant females haul themselves onto the rocky shoreline to give birth and, almost immediately, mate again.

The barren Kalahari landscape offers little protection to its animal inhabitants. Masters of survival, they must overcome drought, dust, wind and heat to survive. Clans of resourceful Meerkats resort to burrowing in the ground to avoid the many predators that await them in the 'land of the big thirst.'

The creatures of the Okavango occupy a mosaic of land and water. Throngs of birds and animals arrive with the seasonal floods, only to recede along with the waters. Permanent residents of this emerald oasis are specially adapted to survive its often unpredictable patterns. At the head of this food chain is the fearsome Nile crocodile.

Three great oceans meet at the southern tip of Africa and three distinct marine ecosystems extend their mingled currents thousands of miles around the continent, creating one of the most complex and varied marine environments on earth. The creatures here have developed unique body shapes, hunting methods and courting rituals to ensure they are adapted to survival in the deep.

Burrowed beneath the African bushveld, animals like the hyena, aardvark, and pangolin shelter in these retreats to sleep and breed. As the winter dry season sets in, wild dogs - the most endangered mammal in Africa - abandon their nomadic existence to give birth in these underground dens.

The towering 60ft canopy of Africa's rain-forests creates a hot, humid habitat where time seems to stand still and seasons never change. Where humans rarely venture, our closest animal relative, the chimpanzee, thrives in the trees. The forest floor is the domain of the largest and most powerful of the great apes, the gorilla.

A reef is an incredible living organism. To survive and flourish, water conditions have to be perfect, only then can tiny coral polyps form thriving colonies. Algae attach themselves to the corals and reef fish soon follow to feed on both and make their home in every crack and crevice. This profusion of life soon attracts a fearsome visitor- Sharks.

Fluctuation between fresh and salt-water, alternating immersion and exposure, temperature extremes, and powerful currents make for extremely demanding conditions in southern Africa's coastal estuaries. Nonetheless, fish, birds, and reptiles thrive here and each year female loggerhead and leatherback turtles travel hundreds of miles to return to their traditional nesting sites.

For long periods, even years on end, the salt pans of Africa are barren and lifeless. When the rains finally come, water sweeps over the salt-encrusted clay, creating vast inland seas just a few inches deep. Thousands of kilometers away, massive flocks of flamingos sense that the drought is breaking and set course for the flood plain.

The Drakensberg is a mighty chain of peaks spanning South Africa, Swaziland and Lesotho. Black eagles and cape griffon vultures rule the air, nesting on perilous cliff faces to avoid predators. However, agile baboons still find their way to the precariously placed nests. The rugged terrain demands carefully adapted behavior of nature's mountaineers.
