Widespread biofluorescence in birds-of-paradise suggests enhanced signaling for hierarchy and courtship displays
New research by scientists at the American Museum of Natural History and the University of Nebraska-Lincoln reports, for the first time, the widespread occurrence of biofluorescence in birds-of-paradise. The study, based on Museum specimens collected since the 1800s, finds biofluorescence in 37 of the 45 known birds-of-paradise species and suggests that this special "glow" is important among males for hierarchy and mating displays. The research is published today in the journal Royal Society Open Science.
