TRAIN WINGS TO FLY
Eagles lay eggs on a cliff or high peak in nest of grass and thorns. When the eggs hatch, the weight of the eaglets exerts pressure and the thorns start pricking the newborns. Then the female pushes the eaglets out of the nest. As the eaglets nearly fall, the male picks them and places them back in the nest.
Meanwhile, the female removes the upper layer of grass, so that the eaglets rest directly on the thorns that prick them. The eaglets are yet to test their wings. Now the male pushes the eaglets out of the nest.
This process continues till such time that the eaglets are able to foresee the danger in falling and start using their wings.
Slowly they realise their ability to use their wings and start flying.
