What is the significance of an ostrich burying its head in the sand?

The idea that ostriches bury their heads in the sand is a myth. Ostriches do not actually bury their heads in the sand. This misconception may have originated from the fact that ostriches sometimes lower their heads to the ground to eat or to check their eggs in nests. The myth of ostriches burying their heads in the sand is often used as a metaphor for avoiding problems or ignoring reality.
