Targeted canary breeding requires certain knowledge in genetics. We got the first useable knowledge about hereditary factors from Gregor Johann Mendel (1822-1884). He is considered the person who began genetics and also created the terms still used today. Up to this time, knowledge about genetics was not known. That's one of the reasons why already appeared very early mutations, but then disappeared again. I. e. the mutation agate was already mentioned around 1700. Then the factor Agate was not mentioned again, until 1910 in the Netherlands this mutation was discovered again.

The birth of coloured canaries was around the turn of the 20th century and can be put down to one of the greatest pioneers in the canary breeding, Dr. Hans Dunker  (1881 -1961) from Germany, a persistent bird enthusiast, who tried to be the first to explain “Piebald” canaries by factors. He also discovered that he could mate a South American carduelid Red Siskin male (Carduelis cucullata) with a yellow canary  female to produced a Red Canary.The occasion was the fact that around 1870 an English canary breeder had caused a scandal by feeding Norwich canaries with chilli to turn them orange. Thanks to his perseverance the canary breeding could evolve enormously. In 1962 the textbook “Farbenkanarien” (Coloured Canaries) was published by the German Mr. Julius Henninger.  All previously known hereditary factors for canaries were described. Since then however, further mutations have occurred. Thanks to all the breeders who since then have developed the canary breeding with a lot of endurance and have written down and taught all the new genetic characteristics.
