Why do they bury the falcon in the dirt and spray it with water after catching it?

Strange information, perhaps not much about the falconry world, is the first thing the falcon hunter does after he succeeds in hunting. "It's not the easy process." He is buried in the sand and poured water.
This is because the falcon after hunting feels humiliated and insulted, and this feeling is reflected by the high and rapid heartbeat, which ultimately leads to the heart exploding and dying.
It was also observed that some falcons after the capture of the self-harm, working on plucking feathers, which eventually lead to death also; that is, the falcons in the case of hunting is a "suicide."
For this reason, hawk hunters bury the body of the falcon only in the sand; to calm his heartbeat, and his head forward and mounted.
It is preferable that the hunter of the falcon, who is away from him after hunting; because the falcon recalls who caught him and does not erase from memory that person, who deprived him of his freedom, and grieves everything that looked at this person, and can die from the severity of grief all that he saw.
When the falcon becomes old when his beak becomes weak and his claws rust, and his wing becomes dislodged unable to carry, there is only a solution of two.
Either a bird remains for the maximum height until its strength ends and dies, or it breaks its beak, its beak and its claws, and plucks the feathers of its wing with a feather.
In this case he returns as he was in the first time light and strong and sharp as if he was born again ...
