A new study has used community science data to reveal species differences in vocal learning by parrots. The study, published in the journal PeerJ, analyzed data from over 1,100 parrot videos collected by citizen scientists from around the world. The videos were analyzed to measure the parrots' ability to imitate human speech, as well as their ability to produce other sounds, such as whistles, clicks, and growls.
The study found that there was a wide range of vocal learning abilities among parrot species. African grey parrots were the most skilled vocal learners, followed by budgerigars, cockatiels, and lovebirds. However, even within these species, there was variation in vocal learning ability. Some African grey parrots were able to learn dozens of words and phrases, while others were only able to learn a few simple sounds.
The study also found that parrots' vocal learning abilities were influenced by their environment. Parrots that were raised in captivity were more likely to learn human speech than parrots that were raised in the wild. This suggests that vocal learning is a skill that can be learned through social interaction.
The findings of this study have implications for our understanding of the evolution of vocal learning in parrots. The study suggests that vocal learning is a complex trait that has evolved independently in different parrot species. The study also provides new insights into the social behavior of parrots and the role that vocal learning plays in their communication.
