The eagle in captivity

My niece who has a large farm in the rural area bought an eagle. After a few months she released the eagle so it can be in the wilds. There is a nearby mountain that the bird would certainly love. But lo and behold the eagle was gone for a day and it came back. They were surprised and thought the eagle was tame.

Day by day the eagle would be there to feed. They give it raw fish and meat. After some weeks they decided that the eagle would want to stay. They opened the cage and the eagle came in. Now the cage remains open and the eagle is staying for a couple of years now.
