This Week in Nature: March 28 – April 3

“It was one of those March days when the sun shines hot and the wind blows cold:
when it is summer in the light, and winter in the shade.”

— Charles Dickens

Here’s what’s happening this week in nature.

Rapid Migration:

Spring migration is urgent. For each species there is a specific optimal time when birds need to be at their breeding grounds to start the birth cycle. In many wetlands throughout the country (big or small), you’ll find larger than normal flocks coming and going. They can create such a spectacle that several state and national parks schedule their tours to coincide with these peak migration times.


Green Leaf:

Chlorophyll reacts to the sunlight from longer days in the spring and transforms carbon dioxide and water into carbohydrates and oxygen through photosynthesis, producing new leaf buds.


Aphid Generations:

Aphid eggs are hatching now and could already be pregnant. Sometimes mother aphids carry embryos that carry their own embryos. This telescoping reproduction strategy results in quick population growth.

About ‘This Week in Nature’

To illustrate the widest range of natural events, I depict the seasonal activities found in the Northern Hemisphere, and I have chosen to present the most intense expressions of each season. My “This Week in Nature” posts are not meant to be specific to any one geographical area. They are intended to evoke the essence of the seasons and to emphasize the cycles of nature. The goal is to simply offer a glimpse of the natural phenomena that make each day an amazing event.

My hope is that your appreciation for nature grows and that you share this appreciation with others. If you enjoyed this post, please subscribe to this blog (at the top) for more. Thank you for reading!
