Pygmy of the Amazon

After staring at this tree for 15 minutes, the little buggers finally showed themselves to me. I could hear them, but they do not make them selves very visible to those with cameras waiting to photograph them..That is until you hum to them, or whistle, or sing. That seems to be the thing they could not resist. Even got them to tilt their little heads like dogs do when they are trying to figure something out.
