And cholla spines are particularly nasty little things, so this wouldn't be my choice
of where to build a home, but I guess they don't call them cactus wrens for nothing.

It was scurrying about this cactus without an apparent care in the world and hardly gave
me a second look, although I was approaching it quite slowly and moved toward it only
when it was looking the other way.

Before it eventually had enough of me (7 minutes) and flew off, it let me get close enough
I was surprised the 20D's shutter noise didn't scare it off, but I've yet to see a wild
bird bothered by it. Movement, on the other hand, will always get them taking flight.
