Two more videos from Boulder Canyon

The first video is a short one of a zebra-tailed lizard demonstrating an "explosive burst of speed". That's why I haven't been able to catch one waving his tail, yet.

Next is a video of the eastern collared lizard. The camera shakes a lot, though, for several reasons. I was trying to sneak up on it, so I was walking very slowly, so I was on one foot a lot of the time. The wind kept blowing me around. Also, I had to keep looking down to see where I could put my feet, and then the camera would point in the wrong direction. At one point in the video I zoom out far enough that you can see how long the lizard's tail is. It's really long. Looks like the tail is about 150% as long as its body.
