My geckos are back! Nature Notes 081210

Last summer I wrote a post about the family of geckos that crawl up our outside wall every evening and this summer they (or new members of their family) are back. They are attracted by the kitchen light and crawl up the outside wall of our house and peer in at me through the kitchen screen. I love watching them. They have tiny suction cups on their feet and they easily crawl up the wall and screen. They seem to appear every evening about 8:00, as soon as it is dark and they disappear by midnight. In fact, if I don't see them as they first appear, then I don't see them that night. They make little chirping noises and feed on the insects that are attracted by the light. I've been outside watering my palo verde tree during the daytime and I've disturbed one of them who seems to enjoy living in the cool grass by the tree. Twice now, as I was watering it, I scared him off and he seems to be a darker color. The three that climb up my wall seem to be lighter, like the one in the photo. I love observing them and hope that they will continue to reside in our yard. I do NOT use any pesticides at all, so that may be one reason why they live and propogate in our yard.
