What's the use of a falcon hat? When will you bring it?

It mainly plays the role of protecting and controlling the eagle, blocking the light with a hat to make the eagle's mood stable, and usually the eagle won't move when the line of sight is bad, which can avoid the eagle's feathers (especially its wings and tail hair) from being hurt. Hawks are usually capped during the day, especially when unattended. The capping technique must be fast and accurate. The size of the hat must be determined according to the eye distance of the eagle.
