What name is given to Native American feathered headgear made of eagle feathers?

War bonnets are feathered headgear traditionally worn by male leaders of the American Plains Indians Nations who have earned a place of great respect in their tribe. Originally they were sometimes worn into battle, but they are now primarily used for ceremonial occasions. In the Native American and First Nations communities that traditionally have these items of regalia, they are seen as items of great spiritual and political importance, only to be worn by those who have earned the right and honour through formal recognition by their people.

Many Native American tribes consider the presentation of an eagle feather to be one of the highest marks of respect. An honored person must have earned their feather through selfless acts of courage and honour, or been gifted them in gratitude for their work or service to their community or Nation. Traditional deeds that bring honour can include acts of valor in battle (including contemporary military service), but also political and diplomatic gains, or acts that helped their community survive and prosper. The esteem attached to eagle feathers is traditionally so high that in many cases, such as a warrior (e.g. Dog Soldiers of the Cheyenne), only two or three honour feathers might be awarded in a person's whole lifetime.
