To each their own when it comes to how they define relaxing. For me, it is sitting in the backyard on a sunny day with my 400mm lens glued to the spot where I know our Hummingbirds will fly in to feed. The goal is a couple of good shots.

Hummingbirds only fly in for about 15 seconds to feed. They are about one inch long and blazingly fast, so there are a lot more missed shots than keepers. I did get a couple I like today. Here is the first.
