Ostriches do not bury their heads in the sand. This is a common misconception that likely originated from a combination of misunderstandings and exaggerations. When faced with a threat, ostriches often squat down and lay their necks flat against the ground, which can give the illusion of burying their heads. This behavior is likely a defensive mechanism designed to make them appear smaller and less threatening to predators. They symbolize speed, independence, agility, and self-reliance.
