The Superb Bird-of-Paradise (Lophorina superba) is a small passerine bird of the Birds-of-Paradise family. The species has an unusually low population of females, and competition amongst males for mates is intensely fierce. This has led the species to have one of the most bizarre and elaborate courtship displays in the avian world.
You've probably seen the weird mating display of the Superb Bird-of-Paradise, but now you can see how he does it. This video is part of the Birds-of-Paradise Project from the Cornell Lab of Ornithology.
