Great article from Gizmodo discussing the research article “Biomechanics of the Peacock’s Display: How Feather Structure and Resonance Influence Multimodal Signaling“:
Male peacocks shake their brilliantly-hued, long tail feathers to attract females in a courtship display known as “train-rattling.” But scientists had never closely examined the biomechanics behind this behavior—until now. A new paper in PLOS One concludes that the frequency at which those feathers vibrate can enhance this iridescent display—even as the eyespots remain almost perfectly still.
