Researcher Aliza le Roux records the vocalizations of gelada bachelors foraging in the tall grasses of Ethiopia's Simien Mountains National Park. These males spend years gaining strength, waiting for an opportunity to take over a group of females for themselves.

Here a gelada baboon shows off his coarse, fluffy pelage, dark brown face and pale eyelids. Like other geladas, this one has a relatively short tail with a tuft at its tipo.

Gelada baboons make several communication calls, including a two-phase bark (deep, loud call repeated every few seconds), rhythmic grunts and shrill barks, which are single, explosive calls that serve as alarm calls.
