Harz Roller (German: Harzer Roller [ˈhaʁtsɐ ˈʁɔlɐ] ) is the name of a breed of domestic canary bred in the Upper Harz mountains of Germany. The birds were bred in the Upper Harz between Lautenthal and Sankt Andreasberg in the middle of the 19th century and achieved European-wide fame. The song of the Harz Roller, like that of the common canary, is clear and consists of alternating beats, trills, and rolls—which is where the Harz Roller gets its name. The special song, which has made this breed a "best-selling export," must be learned. The Harz Roller is also alternatively called the Roller Canary and was also known and spelt as Hartz Mountain Canary in historic American sources.
