Animal Life: A Dream

When a tiny animal is born, the parents will take care of it until it can become independent. When they become old, it's their time to die. In the animal world, only parents take care of their offspring, and the young ones never take care of the old ones. The only exception is the crow, which will take care of its parents when they are old. The young crows will pick up food from nature and feed their elderly parents.
Animal life can be cruel, with only the strong surviving and the weak being eaten. This is the rule of the animal world. One minute, an animal may be very strong, but the next minute, it could become food for a larger animal.
However, in this world, there is a small bird that eats only snake meat, no matter how big the snake is. First, the bird will blind the snake's eyes, and then it will eat the meat slowly afterward.
