Effects of diet on rate of body mass gain by wintering canvasbacks

Article Abstract:

Wintering canvasbacks have shifted their plant diets from American wildcelery to an animal diet of Baltic clams in response to habitat degradation in Chesapeake Bay. Using data gathered between 1990 and 1992, studies were conducted to determine the effect of the diet change on mass recovery rates among canvasbacks. The results indicated that the diet change has a incremental effect on the mass recovery rates of canvasbacks. Consequently, it has suggested that aquatic plant foods should be restored and maintained to increase the survivability of canvasbacks during winter and periods of prolonged deprivation.
