One of the things I've learned over the years of trying to take pictures of critters is that some individuals are easier to approach than others. There are several Road Runners around the refuge but most race into the heavy cover when you get near.
This guy is different.
His curved bill is how I can tell him from all the others; and the fact that he actually seems to like getting his picture taken. Well, maybe not, but he does go about his business like I'm not there.
