text: This myth may stem from the fact that ostriches dig nests in the ground using their beaks.
text: Another possible origin for the myth lies with the fact that ostriches keep their eggs in holes in the sand instead of nests, and must rotate them using their beaks during incubation; digging the hole, placing the eggs, and rotating them might each be mistaken for an attempt to bury their heads in the sand.
