The flying falcon wears:
A hood, which is used in the manning process (acclimatising to humans and the human world) and to keep the raptor in a calm state, both in the early part of its training and throughout its falconry career. Out of all the falconer's aids the hood is the most important piece of equipment. It is essential that the hood fits the raptor in a comfortable way or the raptor will reject the hood outright, making training very difficult.
