The peacock makes eye contact with its tail
The peacock shakes its feathers but somehow keeps eye-spots still.
In an experiment using high-speed video analysis, she and her colleagues determined that the peacock vibrates those feathers at a speed of 25 times per second, yet the eyespots remain stationary. Further analysis revealed the eyespot barbs are locked together with microhooks.
This gives each eyespot greater density, which keeps it in place, as the loose barbs around it shimmer in response to the vibrating background. The peahen is attracted by the mesmerizing quality of this display.
