Everything alive is essentially a mystery, and pigeons, with their extraordinary mental and physical powers, are more mysterious than most. They were domesticated thousands of years ago, long before chickens or ducks, which makes them the bird on Earth to which we have the longest close relationship. Pigeons matter.
If you go to my National Geographic page, and scroll through my photos, you will see a few pigeon pics. Also, a couple of previous blog posts concerning pigeons: here and here.
