It’s important to note that parrots don’t actually ‘talk’; they’re simply mimicking our speech. However, they’re one of a very small group of animals capable of learning sounds and repeating them. Scientists had long thought that this might be due to the size of the parrots’ brains, but it’s also to do with their structure.
Along with hummingbirds and songbirds, parrots have vocal learning centre in their brains called ‘cores’. Unlike other birds with song-mimicking abilities, however, parrots also have a surrounding shell. This shell is larger in parrots that are especially known for their ability to learn and repeat human speech.
