Pretending to have fun is absolutely draining, but watching birds can be fun, depending on the bird. Once I saw a blue heron intently focused on a squirrel hole ready to catch its breakfast, but I had to get to work so I couldn’t stick around. Another time I saw a peregrine falcon eating a freshly killed pigeon, not far from where I saw the heron. And another time I saw an osprey catch a small fish in the river by my building. So certain birds that are interesting to watch.
