The Washington Post, of all places, takes on the topic of squirrel linguistics, breaking the rodents’ chatter down into four sounds. It turns out the quiet “muk muk,” which “resembles a stifled sneeze,” is both the sound baby squirrels make when they require a feeding and the syllables male squirrels utter when they want to bang. It must be exceedingly awkward if anyone ever gets the meaning confused. [WP]
