gray tree frog, hyla versicolor, hiding on the ledge of the eave. I had to stand on a stool and use the flash to get a good photo. He has his eyes closed more than he normally would probably due to the flash. He's about two inches long.
He makes up for his small size with quite loud call. I don't mind; I feel like I'm living in a jungle tree house. Here's a video of what his call sounds like. Just as I was about to shut down my computer last night I glanced out to see if the frog was still there. I didn't see him.
