Abstract
In 1997 we began investigating the use of roadside point counts to monitor the long-term status and trends of Puerto Rican bird populations. If such a methodology proves feasible it may provide the empirical data needed for the development of sound conservation plans for the island's avifauna in much the same way that North American Breeding Bird Survey data are used by the avian conservation prioritization process of Partners in Flight, the U.S. Fish and Wildlife Service, and the Canadian Wildlife Service. By the end of the 2003 field season, we will have the data needed to quantitatively evaluate the utility of the program for tracking the population trends of Puerto Rican avifauna. Here we present data from the 2001 and 2002 field seasons to demonstrate the potential utility of these data for quantifying and portraying avian distributions, abundances, and population trend estimates. In 2001, 27 of the 44 available 5-mile roadside routes (11 stops/route) were sampled between 15 April and 15 May. At each stop a 5-minute point count was conducted. The surveys detected 5,471 individuals representing 70 species. Distribution and abundance maps are depicted for seven endemic species. In 2002, 29 routes were sampled. A total of 6,252 individuals was detected representing 79 species. Significantly fewer species and individuals were detected on wet zone routes as compared to moist and dry zone routes.
