Wilson's bird of paradise - BBC Planet Earth II - Episode 2 "Jungles"

Red birds of paradise display in the treetops. Other members of the family dance in the gloom of the forest floor. This is a Wilson's bird of paradise. He's brightly coloured, but about the size of a sparrow. He's lived most of his life alone, but now he's an adult and he too needs to attract a mate. This little patch of light might help him do so. First, he tidies things up. Showing off in this jumble of leaves wouldn't be easy. And his beauty will stand out better against a plain background. He doesn't want bright leaves to divert a visitor's attention. They all need to go. Even the green ones. Especially the green ones. His stage is set. A central pole and a little patch of light. It's perfect. And now he must hope a female hears his call. He can wait here for weeks on end. At last, a female to take up position. She will judge him by the brightness of his feathers. But for the female to see him at his best, he needs her to perch directly above his stage. Under the light. This might be his only chance to shine. Now, when she's looking directly down on him, he reveals her display for her eyes only. In the gloom of the forest floor, he is a dazzling blaze of iridescent green. The brightest leaf in the forest. And that does the trick. Each animal must find its own way of surviving the competition of the jungle.
