The Muscovy duck (Cairina moschata, Anatidae) is a waterbird with a wide distribution in America, reaching Argentina at its southernmost limit, where the species is threatened. In this study, we develop a species distribution model to analyze habitat suitability for the species in Argentina and assess its potential for geographic conservation in the country. Results show that northern Argentina offers environmentally suitable habitats for the species. At present, the Muscovy duck is not adequately protected in Argentina and a quarter of its suitable habitat has already been lost due to human induced changes in land-cover. In contrast to these threats, Argentina still has conservation potential; we detected suitable habitats in protected areas, where the species was not previously recorded, and its dependence on water lines, which offer conservation opportunities. We suggest carrying out conservation actions outside the current system of protected areas, in areas with high habitat suitability, and along water lines, involving private owners in conservation actions. There is also a need for further field research to confirm the duck?s presence in the potential areas and to reveal more detailed ecological information about its habitat needs.
