The Gelada Baboon is native to the mountain grasslands of Ethiopia and is unusual in eating almost only grass. It is the only baboon or monkey in its genus. (Some authorities do not class it as a baboon.)

Like other baboons, the male (above left) is significantly larger than the female (above right); he has a "cape" or mantle of longer fur around the head and upper body.

The seance: Gelada Baboons spend much of their time sitting grazing and, since they don't need to climb trees, have shorter fingers than other monkeys and hard pads to cushion their bottoms.

Since they spend so much time sitting, females are not able to signal readiness to mate by a red rump like the typical baboons in the "Papio" genus, so both male and female have a couple of triangles of bare, red skin on their chests. It looks as if triangles of fur have been cut away. The females' patches glow bright red and have blistered lumps when they are ready to mate.
