An eagle is a really big and strong bird that lives up in the sky. It has really sharp eyes that can see things that are really far away and it uses its strong wings to fly really high up in the sky and glide around. Eagles are really good hunters and they mostly eat fish and small animals. They also have really big nests that they build high up in trees or on rocky cliffs where they can keep their babies safe. Eagles are really important because they help keep the environment balanced by eating animals that might otherwise overpopulate.
