On a long night hike with Emerson, one of the local guides, and Raul, the caretaker of the Madre Selva property, we heard a distinctive frog call that Emerson and Raul recognized as the call of this species. Emerson told me that the frog usually calls from water-filled tree holes a few feet off the ground, and the three of us spread out to try to pinpoint the origin of the sound we were hearing. In a few minutes, Raul found this frog calling from a tree hole about five feet off the ground. I could see the frog in the hole, but I couldn't maneuver my camera into a position where I both had a good angle on the frog and also could light the frog with my flash. I had to settle for this one super-craptacular partially obscured photo of part of the frog's head.
