Parrots mimic human speech as a form of social communication and bonding. In the wild, parrots use vocalizations to establish relationships and communicate with other flock members. When kept as pets, parrots mimic human speech by observing and learning from their human companions as a way to interact and form a connection with them. Mimicking human speech allows parrots to feel more integrated into their human environment and can also serve as a means of seeking attention or expressing their needs.
