An Australian study saw that, in birds, personality is reflected in singing. The most “explorers” individuals perform songs with multiple different elements, the “aggressive” instead have less complex motifs.
Animals also have a personality, as several studies have now highlighted. A research led by Diane Colombelli-Négrel, of the Australian Flinders University, showed that, in an Australian bird, the personality is also reflected in singing. At the study we dedicate an in -depth analysis on Evidence Network n ° 392.
More aggressive, less complex. Scientists followed males and superb blue wren females (Malurus Cyaneus), which have a marked sexual dwelling: brilliant blue, black and blue the male, gray-brown the female. First of all, they determined the personality of individuals. As? “We measured their tendency to explore them in a new environment and observing how they moved and if they tended to explore it. For aggression we have instead used a mirror: these birds see their reflected image as a rival and respond accordingly”, explains Diane Colombelli-Négrel. Then the animals were freed and their recorded songs. It has thus emerged that the most “explorers” individuals had singing with more types of elements than companions as a lesser trend in exploration; The aggressive had less complex songs, with less syllables (combinations of elements).
The song for birds has a key role both in the choice of the partner (it can be an indicator of the physical form and the good nutrition of the individual) and in the territorial defense, therefore also the personality that emerges from singing could be an information that other individuals perceive.
