Rushy , Ducks have different accents , depending on where the duck was hatched . Hence the different calls . City ducks from say Auckland are loud and talkative ( loud obnoxious caller ) A duck from way down south will roll its RRRRRRsssssss as in QuaRRRRRRRRRRRRRRRRRK (deep raspy caller) Ducks from far north use different again Quack-Churrrrrr . . So Rushy these ducks can move around the country . It takes years of practice to notice there Accents . Hope this helps
