For many, the image of an ostrich with its head buried in the sand is a familiar one. It’s been used as a metaphor to describe someone avoiding facing reality or refusing to acknowledge a problem. However, contrary to popular belief, ostriches do not bury their heads in the sand when they’re scared or to hide from predators. In this article, we will debunk this enduring myth using scientific evidence and trace its origin.
The Reality of Ostrich Behavior
Ostriches, Struthio camelus, are the largest birds in the world and are native to Africa. They possess strong legs that can deliver powerful kicks to potential threats, and they’re equipped with keen eyesight to spot predators from a distance. When an ostrich senses danger, its primary defense mechanisms are either to flee (they can run up to 45 miles per hour) or to lie flat on the ground to be less noticeable. Their plumage often blends well with the ground, providing a form of camouflage.
It’s worth noting that the ostrich’s brain is larger than its eyes, contrary to another popular but incorrect belief. They are intelligent birds that employ various strategies for survival, and sticking their heads in the sand is simply not one of them.
However, from a distance, when ostriches are foraging and eating, they often bend down, and their head and neck can be hard to distinguish from the ground due to their coloration. This might give the illusion of a “buried head” to an observer, especially amidst tall grasses.
Origin of the Myth
So, where did this myth come from?
The idea can be traced back to the Ancient Roman writer Pliny the Elder. In his encyclopedic work, Natural History, written in the first century AD, he stated:
“Ostriches… imagining, when they have thrust their head and neck into a bush, that the whole of their body is concealed.”
This observation, combined with the distant observations of the bird’s feeding behavior, might have led to the belief that ostriches bury their heads in the sand.
Over time, as tales do, the story evolved and took a life of its own. The ostrich became an emblem of denial and avoidance, perpetuating the falsehood further.
Scientific Evidence Debunking the Myth
- Adaptive Behavior: In evolutionary terms, burying one’s head in the sand would be a highly maladaptive behavior. Any ostrich behaving in this manner would be easy prey for predators, which means such a trait would quickly be selected against in the wild.
- Physical Limitation: Burying their heads in the sand would also mean that ostriches are effectively cutting off their air supply, which would be counterintuitive and harmful.
- Studies and Observations: Field studies and observations of ostriches in their natural habitats have never documented such behavior. Researchers studying ostrich behavior, like Dr. Clive Elliott, who has extensively studied wild ostriches in Africa, have never reported any instances of ostriches burying their heads in the sand.
Conclusion
Despite being a popular cultural image, there’s no scientific basis for the belief that ostriches bury their heads in the sand when confronted with danger. Instead, these majestic birds rely on their speed, strength, and camouflaging abilities to evade threats. As with many myths, it’s essential to delve into the science and evidence to discern the truth from fiction.

Remember, just because a belief is widespread doesn’t make it factual. It’s always worthwhile to question, research, and understand the true nature of things before accepting them at face value.
