I watched this Canyon Treefrog, Hyla arenicolor, crawl out of a stream and climb a rock to do as they do, and take on the approximate color of the rock for an afternoon snooze. It takes awhile to take effect, it seems, as this little guy was not at all hidden at first. I set up on a rock and had lunch while I watched it gradually get darker and darker, but left before the change was complete.
