The only bird that will peck at an Eagle, is the crow. He sits on his back and bites his neck. The Eagle does not respond or fight with the crow. It doesn't waste time or energy on the crow. It simply opens its wings and begins to rise higher in the sky. The higher the flight, the harder it is for the crow to breathe. Eventually the crow falls due to lack of oxygen. Stop wasting your time with the crows.
Just take them to your heights and they'll fade.
May you fly to new heights....
