Dylan Dreyer takes a journey to South America's dense and crowded Amazon Rainforest; red howler monkeys, harpy eagles and sloths live in the canopy, while army ants march on the forest floor along with wasps, tadpoles, flies and stick ticks.

Dylan Dreyer explores South America's Pantanal region, the biggest wetland on Earth; parakeets and parrots make their nests in cliffs and trees; a jaguar and a crocodile engage in an epic showdown; ranchers and their cattle play an important role.
