Study finds 37 bird-of-paradise species biofluoresce, aiding mating displays and camouflage.

A new study reveals that 37 out of 45 species of birds-of-paradise exhibit biofluorescence, a trait where they absorb light and emit it as a different color. This phenomenon is more pronounced in males, enhancing their vibrant plumage during mating displays. Researchers from the American Museum of Natural History and the University of Nebraska-Lincoln found that this ability to glow may play a crucial role in hierarchy and courtship among these birds. The study, published in the journal Royal Society Open Science, suggests that biofluorescence could also serve as camouflage for females.
