They found that several observed behaviours form a personality component, which they labelled "Confidence/Aggressiveness". As is commonly known, individual people behave consistently different from each other and these kinds of consistent differences in behaviour are called personality. Studies on species other than humans, from insects to elephants, have found that personalities are widespread in nature. The team consists of researchers from the Czech University of Life Sciences Prague, the University of South Bohemia, Czech Republic, the University of Vienna, Austria, and the University of Turku, Finland and is led by Bruno Esattore from the Department of Ethology at the Institute of Animal Science in Prague. The team of researchers studied personality of red deer with a newly developed questionnaire, as well as observed their behaviours.
