37 of the 45 known species of birds of paradise have feathers that fluoresce.

The glow factor is apparently important for mating displays.

Biofluorescence is a phenomenon that happens when shorter, high-energy wavelengths of light are absorbed by an organism.

It then gets re-emitted at longer, lower-energy wavelength, meaning UV, violet, and blue.
