Ecotourism in the Ibera Marshes


Depending on the season, different animal species can be observed (some of them migratory) as well as plants and flowers in full bloom.

Summer in Iberá (Dec – Mar): Generally, there is little rain and the weather is warm. The majority of the birds are making nests or already with young. Migratory birds are often found passing the summer and playing their annual role here in the wetlands before migrating north again. Aquatic plants such as AMAPOLAS DE AGUA and JACINTOS DE AGUA give plenty of color to the lagoons, while the ORQUIDEA BLANCA and the CARAGUATÁ bloom in the forested spots. Many of the plants are in full splendor due to the excellent combination of heat and humidity. The newly born capybaras follow their mother closely, and she often stops to feed them milk. The caiman alligators, meanwhile, are building nests on the floating islands.

Autumn in Iberá (Mar – June): Temperatures are cooler, and some rains fall. This is a time of little tourist activity, and for this reason the animals are even more approachable than normal. The marsh deer is in its rut (reproduction period), for which it is common to see them up close in groups, the males ramming each other, clashing their horns. The rest of the year they prefer a tranquil and solitary life. The observation of fauna becomes easier as the trees shed their leaves.

Winter in Iberá (June – Sep): Touristic high season, due to the month-long holidays in Argentina. Average temperature of approximately 15° C, but it can fall to some 5° C in the morning. This aids in the sighting of caiman alligator, which being cold-blooded, takes advantage of the available hours for sunbathing: a daily, indispensable activity. They are seen in groups of as many as 20, one beside the other. Some migratory birds come up from Patagonia, fleeing the south´s bitter cold. It is also an ideal time to see rare animals such as the CURIYÚ or the ANACONDA AMARILLA, which climb dried trees and the lie on the rocks of the coast to sleep and sunbathe, maximizing their soaking in of the sun´s rays. The neotropical river otters go out to fish early in the morning, taking advantage of the fishes’ inactivity.

Spring in Iberá (Sep – Dec): Pleasant temperatures, but it can be rainy at times. Take heed of the mosquitoes, and don´t forget your repellant. It is a breeding period for most animals, provoking an explosion of activity. Many migratory bird species arrive and announce their presence. The blossoming and/or flowering of some plant species attract a multitude of butterflies and birds.
