Eagle is a common name for many large birds of prey of the family Accipitridae; it belongs to several groups of genera that are not necessarily closely related to each other.Most of the sixty species of eagles are from Eurasia and Africa.Outside this area, just fourteen species can be found – two in the United States and Canada, nine in Central and South America, and three in Australia.Eagles normally build their nests, called eyries, in tall trees or on high cliffs.

The parents take no action to stop the killing
