How to Beat an Ostrich
          
          Use a long weapon:
          •if you are forced to defend yourself against an Ostrich, avoid close quarters combat.
          •use the closest, longest object that can be used as a weapon 
          •if you have a gun, aim for the Ostrich's main body
          
          Keep to the Side:
          •consider yourself at the most risk when the two of you are face to face
          •stay behind or to the side of the bird as much as possible, to stay clear of its most deadly weapon
          
          Aim for the Neck:
          • consider this to be the Ostrich's weakest body part
          •strike it where it is most vulnerable and least protected, to defeat it quickly
          
          Go for the Legs:
          •if you find yourself behind or to the side of the bird with an easy shot to one of its legs, take it.
          •if given the chance, deliver one or both a blow to upset its speed, balance, and striking power
          
          Dive Into a Thorn Bush:
          •if all else fails and / or the Ostrich is immortal, hope that it forgets about you after you dive into the thorn bush
          •do not leave until you know it is 100% safe
