Identification

Large duck with a sleek body and thin red bill. Breeding males have a dark green head and mostly white body with peachy blush on underparts. Females and immature males have rusty brown head and gray bodies with a cleanly demarcated white throat. Feeds in rivers, lakes, and large ponds by diving to catch fish. Hardy in winter, often staying as far north as open water permits.
