We spent a couple of days mostly trying to see some of the big interesting mammals at Yala National Park, such as leopards (saw one, but not a great look) and sloth bears (missed 'em). But one can only look for mammals for so long before one must go out and find some herps. That's just the way it is. So my guide Udaya Chanaka and I snuck away from Yala one afternoon and drove a few hours to a particular hillside cave system which he knew was occupied by two excellent gecko species. This one is a social gecko, which hangs out in groups of 3-11 individuals. They also lay eggs communally, with a number of females returning to the same spots year after year.
