The Emerald Glass Frog (Espadarana prosoblepon) is a small Centrolenid frog found in Central America and northwestern South America (west of the Andes).

We found a number of these frogs calling in a wet forested areas by a large waterfall. The frogs were calling from high in the trees, well above the water. While we heard quite a number of them, we were only able to find a single individual we could reach.
The call is a high pitched, rapid series of "dik, dik, dik, dik" or "pip, pip, pip, pip" notes usually repeated three times in succession. For the following recording, I had to edit out some of the intervening space as well as filtering heavily so they could be heard over the waterfall.
Here's a longer recording with a bit more of the background noise but accentuating the spacing between the calls of different individuals.
