The Physics of Peacock Tail Feathers Is Even More Dazzling Than We Realized
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.

Be sure to check out the video in the article. It has examples of train-rattling shown in slow motion so you can really see the effect of the feathers vibrating while the eye of the feather is seemingly still.
Random thought - I'm often amused or sometimes just puzzled as to the suggested tribes when creating a snap. I think sometimes the software picks up on something on the page which leads to a suggestion that has nothing to do with the article. Sometimes, though, I just don't see where it's coming from. A couple of the top suggested tribes for this snap were /t/swingdancing and /t/spiders.
