Rainforests circle the equator in a band that holds more species than any other habitat on Earth, and this episode follows the animals that depend on the small clearings breaking up that density. At Mbeli Bai in the Congo, a natural clearing works as a meeting ground where troops of lowland gorillas forage in the open alongside African forest elephants, both drawn out of the cover of the trees by mineral-rich plants they cannot get elsewhere. The camera then moves to New Guinea for the birds-of-paradise, where males of different species have each evolved a distinct courtship routine, from shape-shifting feather displays to precise, almost mechanical dance moves, all aimed at a female who rarely seems impressed on the first try. Narration ties these scenes to a wider point about the jungle's fragility, framing the rainforest canopy and its clearings as a system under pressure from climate change and shrinking habitat. The footage carries the argument, showing a world crowded with species that mostly stay hidden until something like a mineral lick forces them into view.
