Barcelona has been the scenario of a study conducted with gray breast parrots in which it was analyzed to know how social relationships are of these birds and that Connection exists for that reason when they have to communicate with each other.
An investigation published in Royal Society Open Science And where it was clear that for more socialization through these birds, have more vocabulary. «A greater variety of Graznidos and whistles He talks about the position and the degree of fun that these birds have in their communities, “they confirm in their conclusions.
It is the most important result that this study achieved that scientists from the Max Planck Institute for Animal Behavior (MPI-AP) and the Museum of Natural Sciences of Barcelona will come As well as to record what your social life was and how their vocalizations were all this time.
The most social parrots are those who demonstrate in a wider vocabulary in communicating
Currently, Many European cities have the presence of green and clear tropical birds “Gray breast parrots appeared”, they live in huge colonies of urban parks. The number of this type invading parrots, from South America, Fill the air of natural spaces such as those in Barcelona, where an investigation was conducted to know how social relationships of these birds are and their connection with the way they communicate.
The study, published in Royal Society Open Scienceconfirms that a greater variety of Graznidos and whistles Talk about the position and the degree of fun that these birds have in their community. In fact, according to the research, parrots produce a more changing sound repertoire in larger groups.
It is known that animals of species with more extensive social lives have more complex communication. An example of this can be the clicks of the Dolphins or calls.
Two years of thorough observation of the Cotors
Scientists of Max Planck Institute for Animal Behavior (MPI-A) And the Museum of Natural Sciences of Barcelona devoted two years to the thorough observation of 337 gray breast parrots. They documented their social life and recorded a total record of 5,599 vocalizations.
The team investigated sound records in terms of Diversity of repertoireThat is, depending on the number of different sounds they could broadcast and the type of contact they made. “It seems that some species of calls have been used exclusively in social situations,” says the first author of the German center’s research, Simeon Smele.
Moreover, the way they communicated showed what the role of each in the colony was. “Those who had more central positions in the social structure tend to have to have most diverse vocal repertoires, On the other hand, he claims the person responsible for the research at the MCNB, Joan Carles Senar. The female parrots They were those who produced these kinds of sounds, “how suggested that they were the most social sex,” says Smeele.
Communication and friendship between Cotorras
During the investigation they were able to link what some parrots said based on how well they were performed with other members of the community. “For example, The individuals who were very friends, and who often went together, looked less alike, As if they are trying to distinguish themselves acoustically within their small group, “says the German researcher.
However, there is still much to investigate. “The next big step is to better understand the meaning of every sound, a real titanic task, because most social vocalizations occur in large groups with many people who speak at the same time,” he says. The results offer new ideas about how language could have evolved, including those of people and puts social relationships in the center of the issue.
