During October and November 1995, a bird deterrent device (the Marine Phoenix Wailer) was tested in Miramichi Bay, New Brunswick, Canada, for effectiveness in keeping scoter ducks away from juvenile mussel collector lines. Test results indicated that the Wailer was effective in excluding scoters from a circular open-water area within a 500-meter radius.
