Gelada: Ethiopia’s Grass-Eating Monkey
High in Ethiopia’s rugged highlands, where cliffs drop into misty valleys and winds sweep across open grasslands, lives one of Africa’s most extraordinary primates: the gelada. Often called the gelada baboon, this animal is not a baboon in the strict sense, but a close relative of baboons and the only living member of the genus Theropithecus. Its scientific name, Theropithecus gelada, marks it as a survivor of an ancient primate lineage that was once far more widespread across Africa and Eurasia.
What makes the gelada so remarkable is its diet. Most monkeys eat fruit, leaves, insects, or a varied mix of plant foods. The gelada, however, is famous for grazing on grass. It is one of the few primates in the world that has become a true grass-eating specialist, spending much of the day sitting upright on Ethiopia’s highland slopes and plucking grass blades with delicate, almost humanlike precision.
To visitors in the Simien Mountains, the sight can feel almost surreal: a large, mane-bearing primate with a bright red chest patch, surrounded by family groups, calmly feeding like a miniature antelope. Yet behind this peaceful image is a complex animal with a sophisticated social system, a dramatic evolutionary history, and an uncertain future. The gelada is not just Ethiopia’s grass-eating monkey; it is a living symbol of the Ethiopian highlands and one of the most fascinating primates on Earth.

A Primate Built for the Ethiopian Highlands
The gelada is an Old World monkey found only in Ethiopia, mainly in the high-altitude grasslands and cliffs of the Ethiopian Highlands. It is among the highest-living nonhuman primates in the world, regularly occupying elevations between about 1,800 and 4,400 meters above sea level. These conditions are harsh: nights can be cold, the sun can be intense, and food quality changes dramatically with the seasons. Geladas have adapted to this environment with thick fur, strong bodies,
