Signs of the Season Signs of the Season On-Line Forum Spring and autumn are seasons of great change in the natural world.
Migrations take place, plants flower or fruit, courting, nesting, mating, and new births take place.
The changes that signal the new season are very familiar to each of us, but they are often quite different depending on where you live. The study of seasonal changes is called phenology . If you want to share artwork, photographs, or sound clips, be sure to check out the submission guidelines . Your contributions will appear here, along with those of other members from around the world. The yellow and purple crocuses come up just after the snowdrops, then the hyacinths.
