Made up of Brazilian-born mother Juruna and her two cubs Sasgua'a and Saso, this is the second jaguar family to be rewilded in this area. The species had been driven to extinction in this area of Argentina some 70 years ago.
According to conservationists, the return of these jaguars will help the park's ecosystem.
"The jaguar is a prime predator, the top predator in an ecosystem," says Sebastian di Martino, Director of Conservation of Fundacion Rewilding Argentina. "When this species is not present then the ecosystem starts to behave badly."
Officials report that some 200 to 300 jaguars remain in Argentina. The main threats to their species are man-made, such as hunting and the destruction of their natural habitat.
