Natural World - Season 25 - Eps 5: The Falls of Iguacu
The film explores Iguacu National Park on the Brazilian-Argentine border, home to some of the largest waterfalls on Earth. The story follows animals native to this Atlantic rainforest habitat, including kamikaze-like swifts who live behind and fly through the thundering masses of falling water, as well as spotted jaguars and a family of coatis. The film also shows the struggle of park rangers to defend this threatened reserve from opportunistic exploitation.
