 rustling noise by a violent beating of its wings against 

 bushes and shrubs, while the other remains in ambush

The whole length of an adult male Golden Eagle is 

 nearly three feet ; the adult female is still larger. The 

 beak is bluish horn colour, darkest at the tip ; the cere 

 yellow ; the skin of the lore tinged with blue ; the irides

 dark brown, the chin and throat particularly so ; the

 each toe, which is covered with three broad scales ; the 

 claws are black, the outer claw of each foot the smallest
