Seasonal influence of nutrients on the physiology and behavior of captive canvasbacks (Aythya valisineria) Seasonal influence of nutrients on the physiology and behavior of captive canvasbacks (Aythya valisineria)
Captive canvasbacks (Aythya valisineria) were maintained ad libitum on five diets during the winters of 1978-79 and 1979-80 to evaluate the effects of varying protein and energy levels on feed intake and condition. Diets were formulated to simulate either a natural diet high in invertebrates or one high in vegetation. Two diets low in protein and energy simulated stress diets. Feed...
