The reading today in my daily Christian devotional, Our Daily Bread, mentioned that ostriches don't bury their heads in the sand to hide from danger.  I looked it up, and sure enough, that's true.  This website says, "Contrary to popular belief, ostriches do not bury their heads in the sand.  If a predator threatens their nest, ostriches will lay their head against the sand to try to blend in with it."  Ostriches have no need to bury their head in fear, seeing that they can grow to be 10 feet tall, weigh 400 pounds, run 40 mph, and kick and peck violently with their large talons and beaks.
