The Iberá Wetlands, located in Corrientes province in northeastern Argentina, are one of South America’s greatest biodiversity reserves. Covering more than 13,000 km², Iberá is the second-largest wetland system in the world, after the Pantanal in Brazil. Its name comes from the Guaraní word “I-verá”, meaning “shining waters.”
For bird watchers, Iberá is nothing short of paradise. With over 370 bird species recorded, including marsh specialists, raptors, grassland birds, and migratory species, the wetlands offer year-round opportunities for sightings. What makes Iberá truly unique is the blend of ecosystems—open marshes, lagoons, savannas, gallery forests, and palm groves—that create a mosaic of habitats for birds.
