The Puerto Rico Breeding Bird Atlas (PRBBA) project collected and summarized information on the timing of breeding and geographic distribution of 130 breeding bird species on Puerto Rico, and its associated satellite islands and cays. Fieldwork coordinated by the Puerto Rican Ornithological Society (SOPI) involved 344 volunteer observers who contributed to more than 45,500 individual observations of birds from 2004 through 2009. Following standard breeding bird atlas protocol, observers searched for breeding evidence in 479 hexagons while recording bird behavior. Each observed behavior was classified within a hierarchy of behaviors indicating increased likelihood of breeding from simply “observed” (i.e., no evidence for breeding), to “possible,” “probable,” or “confirmed” breeding evidence. Bird observations and breeding status were plotted in a geographic information system (GIS) layer with 479 hexagons (each 24 km 2 ) covering Puerto Rico and its satellite islands and cays. For each species, the highest ranked breeding likelihood category (i.e., observed, possible, probable, or confirmed) was plotted for each hexagon to depict the species’ breeding distribution and probability of breeding in an area covered by the hexagon. In addition, breeding distribution and timing of breeding for each species were related to ecological life zones (or Holdridge life zones) on the islands and the protected areas to estimate the level of protection of the hexagons where the species breeds. Breeding distribution maps are depicted for terrestrial and aquatic birds including 73 native residents, 26 nonnative residents, 16 endemic species, 13 endemic subspecies, and 2 native migrant breeding species. The breeding distributions summarized in this atlas facilitate comparisons with earlier published descriptions of distribution for each species and will serve as a baseline for future studies of avian distributions and their responses to land use and climate change on Puerto Rico, satellite islands, and cays.
