Series 1: 4. The Amazon

The Amazon, where extraordinary animal behaviours reveal the rainforest’s hidden stories. \n\nIn southern Brazil, over a million turtle hatchlings make a perilous dash to the river as black caiman prey on them – a newly filmed behaviour. In Venezuela, a young harpy eagle that has been watched from its earliest days endures intense storms while awaiting its father’s return with food, providing new understanding of life high in the canopy. Also in Brazil, giant river otters hunt together in a coordinated effort, displaying unique social bonds as they corral fish in the shallows.\n\nArmy ants in Ecuador break down their bivouac and march through the forest with a level of precision and cooperation seldom seen. \n\nIn the Pantanal, caiman engage in an elaborate courtship display, their movements sending ripples across the water – a striking look at an ancient ritual.
