a falcon wears them around its ankles

 bird´s nose and mouth

 it makes the bird audible

  a curved pointed nail on each digit of the bird´s foot

 it grows from bird´s skin

 a part of falconry equipment that is worn at bird´s head

 a pair of short leather straps fastened round each leg of a hawk

 a piece of rope tied to the bird in order to control it

 it protects the hand of the falconer

 a bird sits on it
