Three experiments were conducted to determine if reduced consumption of foods with elevated Al levels by black ducks ( Anas rubripes ) was due to taste aversion, conditioned taste aversion or malaise. Black ducks preferred a diet with 1,000 ppm Al over a control diet but ate less of a diet with 5,000 ppm Al. Prior experience with the high Al diet enhanced preference for the control diet. Changes in body weight and food consumption through time suggested that aversion to the high Al diet was a conditioned response to mild malaise.
