There is a swan walking with three young children, the goose mother intends to take her child to the lake to play and swim, when it comes to the lake, suddenly the swan mother sees a wolf that is eyeing them for a meal.

Knowing that, the mother of the goose tells her children to hurry up to the cave, while the goose mum stays silent and puts a wing to the ground, with the intention that the goose mother looks like she is hurt, in the hope that the wolf will prey on her and not the child because the goose mother thinks that wolves prefer to prey on swans who are injured, because it will be easier to catch.

Apparently the goose mother's bait was successful, the wolf seemed to chase after her, while still pretending to be hurt, soon the goose mother ran into the forest, she intended to keep the wolf away from her children who were running towards the canyon, when the mother swan forest stopped , seeing it then the wolf instantly attacked him.

But soon the mother of the goose immediately flew away, so that escaped from the wolves, and went straight to the sanctuary where her children were. But apparently the wolf was still chasing her, as soon as she arrived she was soon the goose mother joined her children, while the wolf only can be silent to see him, because wolves can not swim to catch those who have been in the middle of the lake.

According to the fact there is a bird named killdeer who is often encountered in Mexico who has a technique to protect his son in a way, if there is a predator that approaches the nest then the parent will move away while dragging one wing as if injured, most predators will chase the mother, and without it is realized that the predator will move away from the killdeer bird's nest, and when it feels safe the parent will fly, while the children will flee when the predator is diverted by the parent.
