Puna plover is a small shorebird of high Andean wetlands and saline lakes notable for its restricted Andes distribution and specialized ecology. It occupies montane habitats across nations such as Peru, Bolivia, Chile, and Argentina, and has been the subject of regional conservation efforts by organizations like the World Wildlife Fund and national park administrations. Its study intersects with research institutions including the Smithsonian Institution, Natural History Museum, London, and regional universities in Cusco and La Paz.
The species is placed in the genus Charadrius, which also contains relatives studied by ornithologists at the American Museum of Natural History and the Royal Society. Taxonomic treatments have been influenced by molecular analyses from laboratories associated with Harvard University, University of Oxford, and the Max Planck Society. Historical specimen collections at the Natural History Museum, London and the Field Museum informed early systematic work alongside revisions published in journals such as those by the Linnean Society of London and the American Ornithological Society. Debates over subspecies boundaries have involved researchers connected to the University of Buenos Aires, Pontifical Catholic University of Peru, and the National University of San Marcos.
Adults show a compact body typical of Charadrius plovers, with plumage described in regional field guides used by the Cornell Lab of Ornithology and the Royal Ontario Museum. Morphological measurements reported in studies from the Smithsonian Institution and the American Museum of Natural History include bill length and wing chord compared with other high Andean shorebirds cataloged at the Muséum National d'Histoire Naturelle. Photographic records contributed to citizen science platforms run by organizations like eBird and the Global Biodiversity Information Facility assist museums including the Natural History Museum of Los Angeles County and the Museo de Historia Natural de Lima.
The species is resident or locally migratory in puna grasslands, saline lagoons, and shorelines of the Andes within political regions administered by Peru, Bolivia, Chile, and Argentina. Its range overlaps protected areas managed by agencies such as the National Service of Natural Protected Areas and parks like Sajama National Park and Eduardo Avaroa Andean Fauna National Reserve. Habitat surveys coordinated with universities such as the University of Chile and international programs like the Convention on Biological Diversity map occurrences alongside other Andean taxa documented by the IUCN and regional NGOs including Conservación Amazónica.
Foraging behavior mirrors that of other Charadriidae documented in comparative studies from the British Ornithologists' Club and the Wilson Ornithological Society. Diet analyses by researchers affiliated with the Institute of Arctic and Alpine Research and universities in Lima and La Paz indicate consumption of aquatic invertebrates shared with co-occurring species cataloged by the International Union for Conservation of Nature. Movement ecology research collaborates with programs like BirdLife International and tracking projects supported by the European Research Council and the National Geographic Society. Interactions with predators and competitors are described in regional faunal surveys produced by institutions such as the Museum of New Zealand Te Papa Tongarewa and the Royal Belgian Institute of Natural Sciences.
Breeding phenology has been documented in studies conducted by field teams from the Pontifical Catholic University of Chile and the National University of San Marcos, with nest descriptions compared in monographs published by the British Trust for Ornithology and the Royal Society for the Protection of Birds. Clutch size and incubation observations are referenced in works by the American Ornithologists' Union and captured in datasets curated by the Global Biodiversity Information Facility and the Atlas of Neotropical Birds. Nest predation and chick survival analyses have involved collaborations with conservation organizations such as the Wildlife Conservation Society and academic departments at the University of Cambridge.
Conservation assessments have been undertaken by entities including BirdLife International, the IUCN, and national ministries of environment in Peru and Bolivia. Threats identified by environmental agencies such as the Ministry of Environment, Chile and NGOs like Conservación Patagónica include habitat alteration, water extraction, and disturbance from mining operations overseen by corporations that operate in the Altiplano region. Management actions recommended by specialists from the World Wildlife Fund and research groups at the Smithsonian Institution and University of California, Berkeley emphasize protected area designation, water regulation policies discussed at meetings of the United Nations Environment Programme, and monitoring programs led by regional universities and community organizations.
