Easily recognized by their ski-slope profiles, canvasbacks are common on both coasts of North America during the winter (they breed inland). Both sexes congregate in winter feeding flocks, diving for mussels, clams, and other shelfish. These males (with the species' trademark white backs, rusty heads, and brilliant red eyes) and females (subtle browns) were feeding on clams in a small recreational lake between Mountain View and Palo Alto; another was in Monterey, all in California. |
