Last summer I spent a few weeks in Gamboa, Panama. We lived next to some herpetologists studying the red-eyed tree frog, Agalychnis callidryas. A few nights when they had little to do they took me out with them to a pond a few miles from town in the jungle. We saw a lot of these guys out there. The one in the picture is a male, they tend to stay close to the water when they are calling. The females stay in the canopy and only come down to breed. Along with these frogs we saw a basilisk and some other frogs... I don't know they species of any of the others. (Dominique Wagner)
