Justification
Listed as Least Concern since, although its Extent of Occurrence is probably less than 20,000 km2, it is common and adaptable with a presumed large population, and it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Life History, Abundance, Activity, and Special Behaviors

Habits: Males call during day and night in primary forest. Most intensive calling has been heard in the very early morning during dawn. Calling specimens sit on the ground or in elevated positions on trees, and are not always aggregated around water. One female laid 12 large yellowish eggs. Tadpoles in streams.

Calls: Typically a rapid series of three notes; several (about three) such note series emitted one after the other, followed by long intervals of silence. Very loud and difficult to locate.
