Walia ibex are brilliant climbers. They can stand on tiny rock ledges no wider than a brick. Their hooves have a soft, grippy pad underneath that works like a climbing shoe. Mums teach their kids to climb almost from the day they are born.
The males' horns are the showy part. They can curve back over the head, sometimes reaching a metre or more. The males use them to bash heads in friendly contests with each other to show who is strongest - the sound of horns clashing echoes through the canyons.
Living on a cliff sounds dangerous, but for the Walia it is the safest place. Almost no predator can follow them up onto those ledges. They eat tough little plants that grow in cracks in the rock - food other animals can't reach.
Walia ibex used to be very rare - just a few hundred left in the 1960s. Thanks to Ethiopia's Simien Mountains National Park and a lot of careful conservation work, their numbers have slowly grown again. Visitors today often spot whole groups of them, including bouncy kids learning to climb.
