Recent studies reveal that birds of paradise, primarily found in Papua New Guinea, Indonesia, and Eastern Australia, glow in the dark due to biofluorescence. Research led by biologist Rene Martin uncovered that 37 of the 45 known species possess glow-in-the-dark feathers, which are crucial for mating displays as well as potential communication and camouflage. These unique feathers absorb high-energy light and re-emit it as lower-energy wavelengths. Despite this fascinating discovery, the study of biofluorescence in birds remains limited, indicating a need for more research in this area.
Many species of birds of paradise not only have flamboyant feathers for mating displays but also possess the rare ability to glow in the dark.
37 out of 45 known species of birds of paradise exhibit biofluorescent feathers which may play a role in mating displays and communication.
Biofluorescence occurs when shorter wavelengths of light are absorbed, causing emissions at longer wavelengths, with birds of paradise being an intriguing example.
The current very limited number of studies reporting fluorescence in birds suggests this phenomenon has not been thoroughly investigated.
