The current state of knowledge of neotropical shorebird populations in Argentina and Chile is scarce in comparison to the knowledge of neartic species breeding in North America. Neotropical shorebird species breed in the southern hemisphere and connect their reproductive areas with feeding and resting sites using habitats with diverse ecological features and variable climatic conditions. Populations of some species could migrate totally or partially within the same country and/or across one or more countries. Although, many flocks or individuals could undertake local and/or regional displacements. The objective of this presentation is to provide relevant information on seven focal species (Pluvianellus socialis, Oreopholus ruficollis, Charadrius modestus, Charadrius faklandicus, Chionis albus, Haematopus leucopodus, Haematopus ater), all neotropical shorebirds whose life cycle develops in different environments across southern South America, but we will focus in those migratory populations present in Argentina and Chile. We will present available and up-to-date information on distribution ranges, global population size and regional and/or local trends, major migratory flyways, main breeding and feeding areas, IUCN category, and data from monitoring efforts through banding and/or satellite telemetry. Likewise, we will show maps of species occurrence from data observation from platforms such as e-Bird and Ecoregistros. Finally, for all neotropical shorebird species we conclude the need of increase research efforts in new topics such as phylogeography, and improve those less known, such as migratory routes and population trends. For some species, for instance, Oreopholus ruficollis and Charadrius modestus is relevant to enhance the scarce knowledge related to their reproductive, foraging and habitat use ecology. Lastly, conservation strategies and actions in conjunction with local stakeholders are key to protect populations at multiple sites utilized by this migratory shorebird species.
