Do Ostriches Really Bury Their Heads In Sand?

The Ostrich is the tallest and the heaviest of all birds, but their heads are pretty small

An ostrich can kick with a force mighty enough to kill a lion

When danger approaches, an ostrich will often lie low to hide, stretching its neck along the ground

Its feather colours blend with the soil where it lives. From far away, it looks like the ostrich has buried its head in the sand

Many think that is what ostriches do when they were trying to hide, but that is a myth

It's an optical illusion. Ostriches don't bury their heads in the sand as they wouldn't be able to breathe, according to researchers

They dig holes in the sand to use as nests for their eggs. Several times a day, a bird puts its head in the hole and turns the eggs

So it really does look like the birds are burying their heads in the sand, which lends itself to one of the world's most-used phrases

"Behaving like an ostrich" or "sticking one's head in the sand" are common idiomatic expressions that mean trying to avoid problems or being in denial

Ostriches also stretch their long necks flat on the ground when they sleep, which can also make it look like their heads are buried
