Easily identified by their “bleeding hearts” Gelada baboons are endemic to the Ethiopian highlands and can be found in large troops foraging the grasslands of the Simien Mountains. Here a group of three young males had infiltrated a group of females and begun grooming them. On detecting this intrusion the alpha male charged the interlopers, reasserting his dominance over them and protecting his harem.
