Alarm/distress calls of Canada geese (Branta canadensis) were evaluated by themselves and in combination with racket bombs to determine their effectiveness in frightening Canada geese from nuisance situations at 2 Corps of Engineers campgrounds in Tennessee. Results based on goose censuses showed a significant (P<0.05) reduction in goose numbers from nontreatment to treatment periods at both sites. Goose numbers were reduced an average of 71% when the calls alone were used. The combination of the calls and the racket bombs produced a 96% reduction in goose observations. Although a reduction in geese was observed during the treatment periods, continual harassment would appear to be necessary as reinvasion was noted after treatment was stopped. The scarcity of alternate feeding and loafing sites may have contributed to this lack of long-term control.
