Spring is officially here, and I’m starting to notice the days feeling longer. For me, the increased daylight is a signal that it’s time to break out the camping gear. I feel ready to hit the trail with each uptick in sunshine hours. Birds, too, are noticing the difference.
Throughout the year, most birds use day length to tell what season it is. When daylight extends, the change triggers physiological transformations. It’s how they know it’s time to breed and nest.
