Parrots mimic human speech as a form of communication and social interaction. In the wild, parrots use vocalizations to communicate with each other, establish their territory, and bond with their flock. When parrots are kept as pets, they can learn to mimic human speech by observing and interacting with their human caregivers. Mimicking human speech allows parrots to feel more connected to their human companions and can also be a form of entertainment for both the parrot and the human.
