- Abstract
SUMMARY The Pampas shorebird community is comprised of species from diverse taxonomic and faunal origin. Four major groups can be recognized: North American migrants residing in coastal Buenos Aires Province during their non-breeding season, Patagonian species wintering locally but breeding further south, Pampean species breeding locally, and Brazil-Paraguayan species present during their breeding season. Because of differences among these groups in the timing and migration patterns, community composition shows marked seasonal variation. Both nesting and non-breeding birds use a diversity of habitat types ranging from littoral sandy beaches to upland grasslands. Throughout the year, however, and in all habitat types, non-breeders predominate in species number and abundance. Intra- and inter-specific patterns of aggression suggest both that resources are limiting, and that non-breeding migrants may play an important role in determining breeding community composition.
