==="Head in the sand" misconception===
[[List of common misconceptions|Contrary to popular assumptions]], ostriches do not bury their heads in sand to avoid danger.<ref name=Gosselin/> This misconception likely began with [[Pliny the Elder]] (23–79&nbsp;CE), who wrote that ostriches "imagine, when they have thrust their head and neck into a bush, that the whole of their body is concealed."<ref name=Kruszelnicki/> This may have been a misunderstanding of their sticking their heads in the sand to swallow sand and pebbles to help digest their fibrous food,<ref name=Kreibich/> or, as [[National Geographic Society|National Geographic]] suggests, of the defensive behavior of lying low, so that they may appear from a distance to have their head buried.<ref name=NationalGeog/> Another possible origin for the assumption 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.<ref name="ScienceWorldHeadSand">{{cite web|title=Do ostriches really bury their heads in the sand?|url=https://www.scienceworld.ca/blog/do-ostriches-really-bury-their-heads-sand|website=Science World British Columbia|access-date=2 January 2017|date=11 December 2015}}</ref>
