THE COBALT CANARY

The Cobalt Mutation in Canaries

Originally, the breeder Karl-Werner Weber from Ulm/Germany was specialized in red bronze canaries. 1994, after his offsprings had finished moulting, one of these birds was darker than the others. The cobalt muation in canaries was discovered. In the next few years Mr. Weber bred with a lot of patience more offsprings and can thus confirm the new mutation. The factor cobalt is a autosomal recessive mutation which enlarge the eumelanin areas throughout the plumage to the edge of the wing feathers. A striking feature is that in the cobalt mutation is no brightness of pigmentation in the lower stomach and vent areas. At the moment the cobalt mutation is sufficiently well known in the black and brown series, but also occurs in the agate and isabel series. The striations are similar to those of all classical series, such as black, agate, brown and isabel. The mutation is classified in the non- classic series and meanwhile recognized from the Confédération Ornithologique Mondiale (C.O.M.). The mutation can be combined with all the ground colors (intensiv & non-intensiv), such as yellow, red and white (dominant & recessive). Likewise, combinations with the mutations ivory (yellow & red) and mosaic are possible.

Which Characteristics must a

perfect Black Cobalt canary also

have?

A maximum oxidation throughout the plumage of the black cobalt canary must be present. The striations of the back and flanks must be well marked, also long, wide and unbroken (similar to the classic black serie). The extension to the melanin throughout the plumage gives a dark grey appearance, as dark as possible through- out the plumage through to the end of the feathers, particularly the vent area, include the wing, tail and flanks (regardless for intensiv & non-intensive black cobalt canaries). Brown (phaeomelanin) is absent. Beak, legs and claws are black.

Which Characteristics must

a perfect Brown Cobalt canary

also have?

A maximum oxidation throughout the plumage of the brown cobalt canary must be present. The striations of the back and flanks must be dark brown, also long, wide and unbroken (similar to the classic brown serie). The extension of the dark brown melanin throughout the plumage right to the end of the feathers, particularly the vent area, include the wing, tail and flanks (regardless for intensiv & non-intensive brown cobalt canaries). The dark brown melanin must be dark as possible. Beak, legs and claws are brown.

Which Characteristics must a

perfect Agate Cobalt canary also

have?

Agate is the dilution of the black eumelanin and must be throughout the plumage of the agate cobalt canary, typical of the factor cobalt but reduced (effect of the factor agate). This is very visible specially through the throat, chest belly areas and in particular throughout the vent area (regardless for intensiv & non-intensive agate cobalt canaries). The black eumelanin is reduced to give a charcoal grey appearance. The ground colour looks thus a bit darker. A special feature is the typical agate mustache. The back and flanks must show exhibit fine, short and broken striations (similar to the classic agate serie). Brown (phaeomelanin) is absent. Beak, legs and claws are flesh coloured.
