Does an ostrich bury its head in the sand? 

Contrary to popular belief, ostriches do not bury their heads in the sand: the myth probably originates from the bird’s defensive behavior of lying low at the approach of trouble and pressing their long necks to the ground in an attempt to become less visible. Their plumage blends well with sandy soil and, from a distance, gives the appearance that they have buried their heads in the sand.
