The Superb Bird of Paradise, Lophorina superba, is a small bird native to the rainforests of New Guinea. Because the males far outnumber the females, competition for a mate is fierce, and has, over time, resulted in elaborate competitive courtship displays. Apparently, the average female rejects fifteen to twenty of her performing suitors, before finding The One.
This competitive pressure is understandably stressful for the males. Apparently, they've resorted to music videos, in attempt to be perceived as The Coolest Bird on the Planet.
