David Gessner keenly observes how humans have altered the cycle of the changing seasons and how animals and bird are coping, partly by migration.

After you’ve known a place for a while, you can see one season in another. It’s not mystical or even that hard. I find it reassuring, or at least it was reassuring. These comings and goings of birds and other animals feel like rituals, but that is not really an accurate description since they are the thing itself, not a reenactment, their lives depending on getting the timing right. These timetables have been fine-tuned over millions of years. In the cocoons of our virtual and electronic worlds, it is easy to ignore these primal timetables, but we lose something when we do.
