I always wondered about it.
Ostrich , it is always referred as a bird . But it can not fly.
As the ages of Dinosaurs came to an end , some flying birds ( such as ostrich which was flying then ) , swooped in and took up the newly available niches , preferred to stay on ground , growing larger over the generations , eventually losing the ability to fly .
