Although this duck’s rufous-red is one of its most striking field marks, the male Canvasback is not the only duck in North America with this pattern of coloration. In many parts of its range, this species occurs side by side with the closely-related Redhead (Aythya americana), and a couple field marks must be noted in order to distinguish the two. The Canvasback is slightly larger (20-24 inches), has a longer bill, and is much lighter on the back and flanks. Males have a red head and white body (resembling a sheet of blank canvas from a distance), while females are mostly light grayish-brown. The Canvasback breeds primarily in the northern Great Plains, the northern Rockies, western Canada, and Alaska. Most Canvasback populations migrate south in winter to the southern two-thirds of the United States and into Mexico. In its wintering range, this species is more common inland than the Redhead. Canvasbacks breed in lakes, ponds, marshes and bays. In winter, this species utilizes similar habitats as it does during the breeding season. In summer, Canvasbacks eat both aquatic plants and animals, such as small insects and mollusks; in winter, they feed primarily on plant matter, particul

Il moriglione dorsotelato (Aythya valisineria) è una grande anatra tuffatrice, lunga 48–60 cm e pesante 1270 g. Il maschio adulto ha il becco nero, la testa e il collo rossi, il petto nero, gli occhi rossi e il corpo biancastro. La femmina adulta ha la testa e il corpo bruni e il becco nero. Il loro habitat di nidificazione sono gli acquitrini delle praterie nordamericane. Il nido voluminoso viene costruito con vegetazione in una palude e foderato di piumino. La perdita dell'habitat di nidificazione ha causato il declino della popolazione. I moriglioni dorsotelato si accoppiano solitamente con un nuovo compagno ogni anno, formando la coppia alla fine dell'inverno. I moriglioni dorsotelato sono grandi migratori e trascorrono l'inverno sulle coste degli Stati Uniti, sui Grandi Laghi e in Columbia Britannica in baie d'acqua salata, estuari o laghi. Questa specie è un raro visitatore dell'Europa occidentale. I moriglioni dorsotelato si nutrono soprattutto immergendosi, a volte stando in superficie, cibandosi per la maggior parte di piante acquatiche e di alcuni molluschi, insetti acquatici e piccoli pesci. Il sedano selvatico, Valisneria americana, è il loro cibo preferito ed è all'origine del nome specifico di questa specie. I moriglioni dorsotelato qualche volta depongono le uova nei nidi di altri moriglioni dorsotelato.
