Mar Chiquita is renowned for its exceptional bird diversity, hosting over 250 species of birds, including three species of flamingos (Chilean, Andean, and James's Flamingo). The lake is a crucial stopover point for numerous migratory birds and serves as one of South America's largest waterbird concentrations. Notable species include Wilson's Phalarope, the Andean Avocet, and various species of plovers and sandpipers. The surrounding terrestrial habitat supports mammals such as foxes, armadillos, and capybaras. The lake's waters contain several fish species adapted to high salinity, including silverside (pejerrey) and various crustaceans.
The vegetation around Mar Chiquita is adapted to both saline conditions and semi-arid climate. The dominant plant communities include halophytic (salt-tolerant) species such as Salicornia and various grass species. The surrounding areas feature typical Chaco woodland vegetation with species like algarrobo trees (Prosopis), quebracho trees, and various cacti. Shoreline areas support extensive reed beds and marsh vegetation, particularly in the northern and western sections of the lake. These plant communities play crucial roles in providing habitat for the diverse bird population and helping to prevent soil erosion.
The Mar Chiquita lake basin is a vast endorheic system, meaning it has no outflow to other bodies of water. The lake was formed by tectonic activity and is fed primarily by three rivers: Primero, Segundo, and Dulce. The lake bed consists of sedimentary deposits and salt flats, with the surrounding terrain characterized by alluvial plains and gentle hills. The water is highly saline, with salt concentrations varying depending on water levels and seasonal changes. The lake's shoreline is dynamic, expanding and contracting significantly based on rainfall patterns and climate conditions, which creates unique geological features along its edges.
Mar Chiquita, meaning 'Little Sea' in Spanish, has been a significant geographical feature in central Argentina for thousands of years. The lake was originally formed during the Pleistocene epoch and has played an important role in local indigenous cultures. The area was traditionally inhabited by Sanavirones and Comechingones peoples before Spanish colonization. In 1976, the lake and its surrounding areas were designated as a Multiple Use Reserve, and in 1994, it was recognized as an Important Bird Area (IBA). The lake has experienced significant fluctuations in water levels throughout its history, which has influenced both the local ecosystem and human activities in the region.
The most striking feature of Mar Chiquita is its vast expanse, being South America's largest salt lake and the world's fifth-largest salt lake. The lake's pinkish hue, caused by algae and mineral content, creates spectacular views, especially during sunset. The lake's northern shores feature extensive mudflats and salt pans that create otherworldly landscapes. Several observation points and boardwalks allow visitors to safely view wildlife and the lake's unique ecosystem. The town of Miramar, located on the lake's southern shore, serves as the main access point and offers various tourist facilities, including a museum dedicated to the lake's natural history. The lake's constantly changing water levels create dynamic shoreline features that attract both researchers and photographers.
Mar Chiquita experiences a semi-arid climate with distinct seasonal variations. Summers (December to February) are hot and humid, with temperatures reaching up to 35°C (95°F), while winters (June to August) are mild and dry, with temperatures averaging 10-15°C (50-59°F). The region receives most of its rainfall during the summer months, particularly from December to March. Strong winds are common throughout the year, especially in the afternoon hours, which can affect water activities on the lake. The best time to visit is during spring (September to November) and fall (March to May) when temperatures are moderate and conditions are ideal for birdwatching.

Mar Chiquita National Park protects South America's largest salt lake and surrounding wetlands. The park is a crucial habitat for numerous bird species, including three species of flamingos. It serves as an important stopover for migratory birds and features unique salt-adapted ecosystems.
