An international team of scientists from the Max Planck Institute for Animal Behavior in Germany and the Barcelona Museum of Natural Sciences studied the vocal characteristics of monk budgies found in South America and parts of Europe. They concluded that each bird has a unique vocal tone that allows it to accurately identify a particular individual. The study was published in the scientific journal magazine Royal Society Open Science (RSOS).
Humans have a complex and flexible vocal repertoire, but we can still recognize each other from speaking voice alone, thanks to something called vocal signatures. Our vocal system gives our voice its individual sound.
Many social animals also use their voices to help them identify. For example, in birds, bats, and dolphins, individuals have a unique call sign that allows them to be recognized by group members. However, such sounds encode the identity of the carrier in only one type of signal. Until recently, it was believed that animals and birds did not have their own vocal signatures.
Simeon Smil, an expert at the Max Planck Institute for Animal Behavior, and his colleagues recorded more than 5,000 calls of monk budgies in Barcelona parks. The researchers then used a series of patterns to identify individual birds based on their calls. During the analysis, individual features were discovered in the vocal tonality of parrots.
Scientists then used an artificial intelligence-based tool that is used to identify a person based on the timbre of their speech. After training, artificial intelligence learned to distinguish parrots as well as humans.
According to Simeon Smeal, this discovery raises the possibility that other animal species with flexible speech, such as dolphins and bats, may also have individual vocal signatures.
