These feathers, the researchers found, are linked to smaller feathers that act like sensors.

‘When peacock wing-shaking courtship behavior was simulated in the laboratory, the resulting airflow excited measurable vibrations of crest feathers,’ the researchers wrote in the study, set to be published in a peer-reviewed journal.
