Abstract
SUMMARYThe 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.
