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).
