Country distribution from AmphibiaWeb's database: Puerto Rico


View distribution map in BerkeleyMapper.
This species is found in the Sierra de Luquillo and the Cordillera Central of Puerto Rico. It is found above 450m of elevation (Schwartz & Henderson, 1991).

Life History, Abundance, Activity, and Special Behaviors
The males usually call from bromeliads, rarely from less than 1.5m from the ground. The call is a high chip (Rivero 1998). The calling activity is highest at dawn (Villanueva-Rivera, pers obs).

Trends and Threats
A recent study suggested a decline, but it was limited to one site (Burrowes et al., 2004). The species is abundant where it is found (Villanueva-Rivera, pers obs).
