The horned grebe or Slavonian grebe is a relatively small waterbird in the family Podicipedidae. There are two known subspecies: P. a. auritus, which breeds in the Palearctic, and P. a. cornutus, which breeds in North America. The Eurasian subspecies is distributed over most of northern Europe and the Palearctic, breeding from Greenland to western China. The North American subspecies spans most of Canada and some of the United States. The species got its name from large patches of yellowish feathers located behind the eyes, called "horns", that the birds can raise and lower at will.
