Dendropsophus marmoratus
(Laurenti, 1768)
Madre Selva field station, Depto Loreto, Peru. January 12, 2011.
Many of these frogs look like a splat of bird poop, or a bump on the bark of a tree, or both in some cases. They are about the same size as the gray treefrogs (Hyla versicolor and H. chrysoscelis) around my home back in the United States.
