One way to keep track of changes in the environment around you is by starting a naturalist journal. All you need is a blank notebook and something to write with. Every time you notice something unique about animals and their behaviour outside, write the date and your observation. For example, you may record the first day you see geese flying south in a V-formation in the fall, the first time you see birds building a nest, or the first time you see bees pollinating in the spring. You could also record the first time it freezes overnight, the first snow of the winter, or the first time you see specific flowers bloom in the spring. If you add to this journal every year, over time you will gain a better understanding of the rhythms of nature where you live — and how those rhythms might be changing.
