The Mburucuyá National Park in the Argentine province of Corrientes is an excellent protected area to see the wildlife of the region. There are several species that are frequently seen, some of which are not so easy to find elsewhere.
Among the mammals, the capybara (Hydrochoerus hydrochaeris) is often found near watercourses or land with water. It is common to find the gray brocket (Mazama gouazoubira) in the vicinity of the campsite or crossing different roads. At night, crab-eating foxes (Cerdocyon thous) and pampas foxes (Lycalopex gymnocercus) cross the main road 86 that crosses the park. The crab-eating raccoon (Procyon cancrivorus), which is not an easy species to spot elsewhere, is also often recorded along this road.
Among the armadillos, the yellow armadillo (Euphractus sexcinctus) is diurnal and usually appears in plain sight. On the other hand, the nine-banded armadillo (Dasypus novemcinctus) is more elusive and is usually found at night.
Of the reptiles in the Portillo Stream, the black yacaré (Caiman yacare) is common, and the broad-snouted caiman (Caiman latirostris) is also seen in the park, although less frequently.
