In my experience, parrots usually begin swearing because doing so usually stimulates a response from a human auditor; usually laughter or perhaps the utterance of a statement such as "woah - you are a naughty bird." Responses like this signal the bird that his signal is getting through to human members of "his flock." If you want your bird to stop swearing, the best thing to do is just to bite your tongue and display a poker face.
