Calilegua, tucked into the eastern slopes of the Andes in Jujuy Province, harbors an estimated 500 species -- 270 confirmed and perhaps 230 more awaiting identification. But the birds are only the most visible residents. Jaguars still hunt in these forests. Tapirs leave footprints in the mud along riverbanks. Ocelots, pumas, and jaguarundis slip through the understory. Created in 1979 to preserve the Yungas -- the subtropical cloud forest that ranks as one of Argentina's two most biologically diverse ecosystems, alongside the Misiones rainforest -- Calilegua is where the country's tropical wildness reaches its densest concentration.

Photo credit CC BY-SA 2.0. The jaguar is the largest predator in the Americas, and Calilegua is one of its last strongholds in Argentina.
