text: I'm offended by the "Ostrich like behavior remark".  This is supposed to be a scientific paper, not a social rag.  His Ostrich remark is curry to the popular but incorrect belief that Ostrich  stick their head in a hole in the ground when afraid.  When at a "nest" a standing father (they do the care taking) puts his head to the ground, it's to count heads or give specific care.  Original white settlers saw their head go to the ground and incorrectly thought they were putting their head in a hole in the ground and it became a very popular story.    I think using an incorrect statement to bolster a scientific thesis is counterintuitive. And ignorant.
