The only bird capable of killing people with one blow, it is difficult for 90 pounds, not afraid of fierce beasts, because it kills dogs and breaks glass.
One of the unusuality of this bird is that the female lays eggs, and the father takes over egg incubation and breeding chickens.
While the female goes in search of a male for a marriage.
This is how their life cycle takes place.
From childhood it is deprived of maternal tenderness and maybe it makes it dangerous and stubborn.
