Parrots may do more than simply mimic human speech. A new study suggests the birds could be using names to identify specific people, animals and even themselves, much like humans do in everyday communication. The research, published in the journal PLOS ONE, examined hundreds of recordings of captive parrots and found evidence that some birds use names in meaningful ways rather than just repeating words they hear. The study was led by Lauryn Benedict of the University of Northern Colorado, working with longtime collaborator Christine Dahlin and researchers from Austria. Instead of studying parrots in the wild, the team focused on pet parrots living alongside humans. These birds are regularly exposed to human conversations and often hear names being used in daily life. Using data from the ManyParrots Project, researchers analyzed survey responses and audio recordings from more than 880 parrots. Nearly half of the participants provided examples of parrots saying names. Among 413 recordings containing names, researchers identified 88 cases in which birds appeared to use names to refer to specific people or animals. The findings suggest that some parrots associate particular names with individual people rather than using them as general labels for all humans. Researchers say names play an important role in helping humans manage social relationships, and some animals may use similar vocal signals to recognize or address one another. However, Dahlin cautioned that scientists cannot yet say parrot naming behavior is the same as human naming systems because the intentions behind animal communication remain unclear. The recordings also showed that parrots use names in different ways. Some birds repeatedly said their own names to attract attention, indicating that names may serve various social purposes depending on the situation. According to the researchers, the study suggests parrots have both the mental ability and vocal skills needed to use names flexibly. In some cases, they may even refer to individuals who are not present at the time. The findings add to growing evidence that parrots possess sophisticated communication abilities, while also highlighting how much scientists still have to learn about how animals use sounds to identify and communicate about one another.The researchers say further studies are needed to better understand when and why parrots and other animals use name-like vocal signals.
