The Ethiopian Highlands hold two animals found nowhere else: geladas, the world’s only grass-eating monkey, and Ethiopian wolves, the rarest canid on Earth with fewer than 500 individuals left. Geladas spend the nights sleeping sheer cliffs where they are safe from predators, climbing up to the grasslands above each morning to socialise and feed in herds of several hundred animals. The wolves live on afroalpine plateaus. In the mornings, having slept out in the grassland overnight, they greet their fellow pack members before setting off to patrol the borders of their territory. The rest of the day is largely spent hunting rodents.
