Down to Earth- Flightless Birds

birds that, through evolution, lost the ability to fly.
The concept of flight is intimately connected to birds, but some birds, called flightless birds, don't fly. Instead, some birds develop other ways to get around and no longer need their wings. These birds often develop better plumage camouflage, more muscular legs for running, specialized feet for swimming, or other adaptations that help them survive on the ground in their native habitat.
