You may be familiar with the various memes detailing the fact that once you reach middle age, you're automatically sorted, Harry Potter hat-style, into one of a handful of hobbies, such as sourdough bread making, gardening, or bird watching. I can't contradict this, since I'm a middle-aged person who got sorted into bird-watching. But I do know that enjoying birds and their various activities is fun for all ages. Birds are beautiful, interesting, and unpredictable, and it's fascinating to keep a running life list of all the birds you've seen and hope to see in your lifetime.
