Harz Roller 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. Since 2001 there has been a Harz Roller Museum in Sankt Andreasberg.
By patient breeding a breed of canary was able to be produced that had a very pleasant, melodious song, full of variety and delivered with an apparently closed beak.
The breeding and sale of this popular breed of canary was an important secondary occupation for the mining folk as was the making of cages for the birds. Especially in the second half of the 19th century the business for these canaries boomed. In contrast to widespread legend, the birds were not used in the mines to indicate the presence of oxygen, they were too valuable for that. The Harz miners used captured wild birds for that purpose.
