The Great Chaco offers impressive wildlife, with good chance of seeing some of South America’s charismatic big mammals like jaguars, pumas and tapirs. It also hosts reptiles and birds in abundance, many of which are restricted to this ecoregion. You will enjoy a unique landscape with salt lakes that hold great concentrations of water birds and the dunes of Médanos del Chaco National Park (7 days tour) with its arid vegetation and the palm savannahs of the Humid Chaco.This tour will give you a chance to see Chaco endemic birds like Quebracho Crested-Tinamou, Black-legged Seriema, and Black-bodied Woodpecker. Lowland Tapir, Puma, Giant Anteater and Chacoan Peccary are amongst the mammals we may encounter: the last of these was presumed extinct when it was described from fossils in 1930. It came as a surprise when it was rediscovered in 1972, to become the (then) third and largest peccary species known! Today, the Paraguayan Chaco holds the main population of this species.
