America's Wild Seasons

As plunging temperatures bring nature into winter, some animals flee south to find milder climes. But others are determined to tough out the brutal cold.

In autumn, change sweeps across America. As the trees greet the chill with a blaze of color, it's make or break time for animals. Time to pull up stakes, make last minute preparations, and often find a mate before the cold sets in.

Summer is the time of plenty across America. It's a chance for animals to reap nature's bounty while they can. The year's young begin to explore their world, while new parents make use of the long days to make sure they grow up strong.

Across the continent, the land and its wildlife breathe in warmth and renewal. For some animals, courtship rituals begin to heat up as battles for dominance break out. For others, it's the time to tend to brand new life.
