Here we are on the Serengeti Plain in Africa, where an ostrich has abandoned an egg and a hungry jackal means to make a meal out of it.
现在我们在非洲大草原上，一只鸵鸟刚刚下了一个蛋，一只饥饿的豺狼瞄准了这只蛋，决定美餐一顿。

但是，这只兴致勃勃的动物打错了算盘。
It's just a little too big, a little too slippery, a little too everything for the jackal.

Whatever it is, it works. The vulture finally cracks a hole big enough for its beak.

The vulture is one step closer to mealtime than the jackal, but it's not home free yet.
秃鹰的美餐比豺狼快了一步，但是还不能放松警惕。
