Distribution and Habitat
Country distribution from AmphibiaWeb's database: Madagascar
Ankarana, Benavony, Berara forest, Lokobe, Manongarivo, Marojejy, Montagne d’ Ambre, Nosy Be, Nosy Komba, Tsaratanana (Andampy campsite).
It has been recorded from sea level up to 900m (Andreone and Raxworthy 2008).
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.
Trends and Threats
This species is 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 (Andreone and Raxworthy 2008).
