The gelada (Theropithecus gelada, Amharic: ጭላዳ, romanized: č̣əlada, Oromo: Jaldeessa daabee), sometimes called the bleeding-heart monkey or the gelada baboon, is a species of Old World monkey found only in the Ethiopian Highlands, living at elevations of 1,800–4,400 m (5,900–14,400 ft) above sea level.
Dunbar then went on to the Department of Psychology of the University of Bristol and completed his PhD in 1974 on the social organisation of the gelada, Theropithecus gelada, a monkey that is a close relative to baboons. [22] He spent two years as a freelance science writer. [10]
For instance, the females in hamadryas baboon harems are not usually genetically related because their harems are formed by "kidnapping" females from other harems and subsequent herding. [1] In contrast, gelada harems are based on kinship ties to genetically related females. [7] Multiple harems may assemble into larger groups known as "clans ...
Old World monkey genera include baboons (genus Papio), red colobus (genus Piliocolobus), and macaques (genus Macaca). Common names for other Old World monkeys include the talapoin, guenon, colobus, douc (douc langur, genus Pygathrix), vervet, gelada, mangabey (a group of genera), langur, mandrill, drill, surili , patas, and proboscis monkey.
Baboon mating behavior varies greatly depending on the social structure of the troop. In the mixed groups of savanna baboons, each male can mate with any female. The mating order among the males depends partially on their social ranking, and fights between males are not unusual.
A new study looked at how the behaviour of bonobos, chimpanzees, western lowland gorillas and olive baboons changed as people started to return to zoos. As visitors returned, bonobos and gorillas ...
In the wild, locomotor behavior of these baboons vary as a result of their need to find food and to avoid predators. [17] Gelada baboons use what is known as a "shuffle gait", where they squat bipedally and move their feet in a shuffling motion. They tend to use bipedal locomotion when traveling short distances.
Robin Dunbar originally studied gelada baboons in the wild in Ethiopia, and has done much to synthesise modern primatological knowledge with Darwinian theory into a comprehensive overall picture. The components of primate social systems 'are essentially alliances of a political nature aimed at enabling the animals concerned to achieve more ...
