These geese have mastered the art of base jumping. As a baby, they were born to take this tremendous risk to meet their parents. Within a few days of hatching, goslings must jump off of high cliff faces, where their mother built the nest to avoid predation and plunge below. This is so they can finally meet their parents who are foraging on the grass below the nest, waiting for their arrival. Because of the extreme risk they take, only about a third of chicks survive the first couple of days. They can survive the fall because of their soft bones which cushion their crash (WWT).
