Summary
| Description |
English: Real-time and high-speed video of a peacock eyespot feather vibrated by a mechanical shaker. https://www.youtube.com/watch?v=yTfk5Izepfo When peacock eyespot feathers are vibrated at 25.6 Hz using a mechanical shaker, the eyespot remains relatively stationary compared to the rapidly moving and flickering loose green barbs. This motion mimics what is observed during natural courtship displays. The 25.6 Hz frequency used in this example is the average frequency of peacock train-rattling displays. |
