Do cockatiels have vocal cords

Yes, cockatiels do have vocal cords. But usually only males tend to 'show' that sound off by learning to repeat the Words that it often hears or can sing a pretty song that it heard from somewhere. The females seem to be more quieter with Words but can chirp the loudest chirp that you have ever heard! Some of the chirps can be ear peircing! So it depends if you would like a bird that repeats anything you say or a loud chirp every second for at least ten minutes at a time.
