Of the few birds that can imitate human speech, including mynah birds, crows, and ravens, parrots are clearly the best at it—they give TED talks, speak multiple languages, and even front heavy metal bands. So why can parrots talk when our closer primate relatives cannot? Parrots are vocal learners, meaning they grasp sounds by hearing and then imitating them. Although several other bird species can discern and repeat sounds, parrots are the pros. Erich Jarvis, a Duke University neuroscientist and vocal learning expert, recently published a study in Plos One explaining why. Any bird that’s a vocal learner has a part of the brain devoted to this, called the ‘song system.’ But in parrots, the song system has two layers—an inner ‘core,’ common to all avian vocal learners, and an outer ‘shell,’ which is unique to parrots. Jarvis thinks that th...
