Regional Differences
Horned Grebes of North America (subspecies cornutus) are paler above than the Old World subspecies, often called "Slavonian Grebe" (auritus). Slavonian Grebes have chestnut, rather than buffy, “horns” (the plumes at the sides of the crown in breeding plumage); and in winter, their crown color is glossy black, unlike the flat gray color of North America's cornutus.
