3. Not all Parrots can fly well, not because they have colorful feathers
In some places it is common to clip the flight feathers on Parrots right about the time the bird would first attempt flight. If this happens (or you keep them on a cage that is too small to allow flight) during that time in development when flight should be happening, it can lead to a loss in flight for the rest of that bird's life. Teach them to fly.
