The freezing temperatures and strong snow storms that are expected during the bitter Antarctic winter, are not the most likely place you would expect to find animals breeding. However, when the temperatures begin to turn, hundreds of the world's largest penguins begin to come together to breed.
The emperor penguin, which is the only animal capable of withstanding the Antarctic winter on the open ice, can walk up to 120 km to get to its breeding grounds. There can often be thousands of emperor penguins in one place, which serves a useful purpose when the females leave the males to look after the eggs while they go out to sea to gather food.
Winter is now well and truly under-way and as the snow settles on the ground animals all over the world are preparing themselves for the cold days ahead. Animals often change their behaviour during the winter in order to more successfully survive the bitter cold.
A number of animal species particularly birds, migrate (travel) to warmer climates to escape the northern chills. Numerous birds including geese and cranes fly south to South America and Africa to get some winter sun before returning north when the weather begins to warm in the spring.
