Blood chemistry and hematocrit of captive and wild canvasbacks Blood chemistry and hematocrit of captive and wild canvasbacks
Blood chemistry and packed cell volume (PCV) did not vary among groups of captive canvasbacks (Aythya valisineria) maintained ad libitum on 5 diets varying in metabolizable energy (ME) and protein. Ducks fed low quality diets increased their consumption so that all ducks were obtaining similar amounts of energy and protein. Some variables, including cholesterol, were found to differ...

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...

Seasonal energetics and behavior of captive canvasbacks (Aythia valisineria) Seasonal energetics and behavior of captive canvasbacks (Aythia valisineria)
Dramatic changes in the food habits and distribution of Chesapeake Bay canvasbacks (Aythya valisineria) generated a desire to better understand the energetics and behavior of this species on its wintering grounds. Captive canvasbacks were maintained ad libitum on 5 diets during the winters of 1978-80 to evaluate varying protein and energy levels in the diets. Food consumption, weight...

Food habits of diving ducks in the Carolinas Food habits of diving ducks in the Carolinas
Food habits analyses were conducted on 264 diving ducks (7 species) from North and South Carolina during the 1970'S. The Baltic clam (Macoma balthica) was the predominant food among canvasbacks (Aythya valisineria) from the Pamlico River area, whereas sago pondweed (Potamogeton pectinatus) predominated in birds from impoundments in North and South Carolina. Shoalgrass (Halodule...
