Neither ostriches, or flamingos bury their head in the sand.
Yes

Answer 1: yes when they sleep Answer 2: Answer #1 is a myth. Ostriches have never been documented to ever stick their heads in the sand either when sleeping or when frightened. How are they going to breathe if their heads are in the sand when they sleep? Let alone be able to hear any predators sneaking up on them. You can't hear very well when you have your head in the sand in comparison with having it tucked under your wing. So the answer to the original question is: they don't.
yes
They can only eat with their heads upside down.

Ostriches and Emus supposedly bury their heads in the sand when frightened, but it is not actually true.

they are horns! :)

grains of sand will stick together when wet because of the property of water known as cohesion. cohesion occurs because the water molecule will become attracted to the sand because water will become polarized
