The Puerto Rican Breeding Bird Survey
The Puerto Rican Breeding Bird Survey (PRBBS) is a long-term avian monitoring program that was begun in 1997 with the purpose of monitoring the status and trends of Puerto Rican breeding bird populations over time.  The survey consists of 8-kilometer (5-mile) routes randomly located along local roads.  There are currently 44 routes dispersed among the three major ecological life zones (dry, moist, and wet) of Puerto Rico (Figure 1).  Stops are located at 0.8 km (0.5 mi.) intervals along these routes (totaling 11 stops), where the observer records every bird seen or heard within 0.4 km (0.25 mi.) during a five minute period.  Routes are run once per year between 15 April and 15 May.  Requirements for participation are the availability of suitable transportation to complete a survey, good hearing and the ability to identify all breeding birds in the area by sight and sound.

We are always looking for skilled observers to participate in the PRBBS.  If you are interested in conducting a survey between April 15 and May 15 or would just like more information about the program, please contact one of our island coordinators or the USGS office directly.
