Life History, Abundance, Activity, and Special Behaviors

Habits: Found along streams and in swamps. Males call from hidden positions during the day and often from more open sites on the stream border or in the stream at night. Eggs are deposited in the leaf litter or on rocks next to the water, tadpoles are flushed into the stream after hatching and develop there.

Calls: A series of 4-5 pulsed notes of low intensity.

Breeding takes place in slow-flowing streams (Nussbaum and Vences 2008).

Threats

Major Threats
It is generally not seriously threatened, since it is very adaptable. However, some of the cryptic species within the complex might prove to be threatened, especially by pollution of streams, and extreme opening up of the habitat.
