Great pics. If you want to get close to them while they are perched, go out early on a cool morning in the summer. They sit very still until the sun comes up and warms them up. Take a flash with a diffuser or a reflector to get some light on them. A bonus is that many times they have dew on them as well that can make the pic interesting. The one I show here was during the day. He just happened to land on a wood stake next to my chair while I was out shooting hummingbirds.
