Meet the new mascot “Opal” the peacock. She is an opal white eyed peacock. Did you know that A female peacock has special sensors in her crest that allow her to feel the vibrations of mate who may be located far away. The feathers are "tuned to vibrate at the exact same frequencies at which a displaying peacock rattles his tail." Whenever a male peacock fans his tail, he shakes it at a rate of 26 times a second, creating a pressure-wave that literally rattles the female's head for attention. Crazy.
