I have three parrots, Sully was clipped for over 7 1/2 years before I got him, and although he is fully flighted now he only flies from his cage to the floor or from the floor to the cage. He does not take flight unless I launch him off when I am holding him. My home is small and he is a big male ekkie so a few flaps are all he gets because he is so large. Louie my BFA, has always been flighted I have been told so he came to me flighted, but he is like a lumbering giant that is top heavy. He takes short flights, but then my home like I said each room is small. Now my TAG, Ana Grey came to me clipped and is a regular little missile after she became flighted after a year and can maneuver and turn corners no problem. She is amazing to watch. She is tiny and very fast. Ana Grey use to quiver before she could really fly. She would test her wings daily, she wanted to fly so much. She would quiver before she launched herself..... like in anticipation. And each time she became better. Now she is a wiz to watch.
