"Play dead. In a 1918 article in The Atlantic magazine, former President Theodore Roosevelt wrote, "If, when assailed by the ostrich, the man stands erect, he is in great danger. But by the simple expedient of lying down, he escapes all danger." The experience of ostrich farmers, naturalists, and adventurers has largely confirmed Roosevelt's observation. Since ostriches kick forward and downward, the chance of injury is much lower if you lie face down on the ground and cover your head and neck with your arms. Your back will still be exposed, but this is much safer than if your front were open to attack. Additionally, the ostrich is not able to kick very effectively at an object on the ground, and eventually it will lose interest if you play dead. The bird will still likely stand on you--it's been described as dancing by some who've gone through the experience--and it may even sit on you for a while, but it will most likely not rip you open if you do this equivalent of burying your head in the sand."
