Seventh, Peacocks were a delicacy in medieval times. The birds were plucked, roasted and then re-dressed in their feathers to appear in their original The birds may have looked beautiful, but they reportedly tasted terrible. “It was tough and coarse, and was criticized by physicians for being difficult to digest and for generating bad humors,” writes Melitta Weiss Adamson in her book Food in Medieval Times.
Eighth, They can fake it. These birds aren’t just nice to look at, they’re also clever, according to one recent study. When peafowl mate with peahens, they give out a loud “copulatory call.” Canadian researchers Roslyn Dakin and Robert Montgomerie discovered that the birds can “fake” this call to attract more females. As the BBC’s Ella Davies put it, “By pretending they are mating when they are not, the birds could convince females they are more sexually active—and therefore genetically fitter—than their rivals.” Infact, one-third of the calls heard by researchers were fake, and the birds that made them scored the most hookups. Sneaky, sneaky.
Ninth, Their feathers are covered in tiny crystal-like structures.
What makes the peacock’s feathers so brilliant? Microscopic “crystal-like structures” that reflect different wavelengths of light depending on how they’re spaced, resulting in bright fluorescent colors. Hummingbirds and shimmering butterflies have mastered a similar visual effect on their own wings.
