Nature in Autumn

Fall is one of the best times of the year. I love the Fall. I think it is my favorite season of the year. Where I live in the mid-Atlantic region, the trees put on a spectacular foliage display. The days are clear, crisp and cool. I take long walks and breathe deeply.

Autumn is a season of change from summer to winter. It is known as Fall in some parts of North America because of the falling leaves of deciduous trees.

Autumn begins with the Autumnal equinox. As the earth tilts closer to the sun, days become shorter and nights grow longer.

September, October, and November are the autumn months in the Northern Hemisphere. In the Southern Hemisphere, autumn is from March until June.

Autumn ends with the winter solstice and the beginning of the winter season.

This is harvest time. Gardeners and farmers gather apples, pears, pumpkins, squash, and corn. The first killing frosts signal the end to the big harvest.

Animals in Autumn

Many animals begin their migration to milder temperatures and steadier food supply. Birds migrate along the flyways of North America. Birds of prey migrate south to find more abundant food sources.

Some animals hibernate including bats, chipmunks, and woodchucks. Bears go into a deep hibernation-like sleep.

Many insects die as the colder weather of winter approaches. Some insects migrate deeper into the ground. But there are other insects that hibernate in the egg, larval or pupal stage. Several species of butterflies migrate to warmer climates.
