           The Jaspe Mutation in Canaries

The  jaspe mutation has been recognized in 2014 from the Confederation Ornithologique Mondiale (C.O.M.). It is not a mutation appearance in the canary bird, but another case of gene indroduction from the Hooded Siskin (Spinus magellanica) In [1999] the breeder  José Antonio Abellán Baños from Murcia/Spain succeeded in crossing the factor into the canary. This mutation inherits autosomal and has a semi (co) dominant character. It can occur as single- factor (SF) and also as double-factor (DF). At present, the C.O.M. recognized only the single-factor (SF) and only a combination with the series black, brown and agate.  As a result of the excessive dilution in the isabell series, no standard is currently planned. Despite of the double factor jaspe in birds, no lethal factor is present. In the classical canaries the mutation jaspe exerts a remarkable dilution of the black and brown melanin structure. Between the dark zones, the melanin becomes lighter. The phaeomelanin and the lipochrome are not affected by the presence of the jaspe factor. The down feathers (down of birds) are in the black series grey, in the brown series hazelnut and in the agate series light grey.

The Mutation Jaspe (single-factor) of the Black series

On the back, the shafts of the feathers and the edges are darkgrey. Between the dark zones the tint becomes lighter grey (steel grey). The back shows aligned parallel striations. The flanks show long and wide striations as possible, which converge in the middle of the chest. The striations on the head are well aligned. The mirrors (= visible reduction of melanin in the first flight feathers) are clear but not too extensive (maximum 60% of the visible length of the first flight feathers and 40% of the outer tailfeathers). Absence of visible phaeomelanin. Beak, legs and claws are black. Depending on the lipochrome and the category, following jaspe canaries in the black series are recognized: - Yellow intensive (SF) - Yellow non-intensive (SF) - Yellow mosaic mozaïek (SF) - Yellow ivory intensive (SF) - Yellow ivory non-intensive (SF) - Yellow ivory mosaic (SF) - White Dominant (SF) - White Recessive (SF) - Red intensive (SF) - Red non-intensive (SF) - Red mosaic (SF) - Red ivory intensive (SF) - Red ivory non-intensive (SF) - Red ivory mosaic (SF) (SF) = Single-factor

The Mutation Jaspe (single-factor) of the Brown series

On the back, the shafts of the feathers and the edges are greyish brown. Between these zones the tint becomes lighter greyish brown. The back shows aligned parallel striations. The flanks show long and wide striations as possible. The striations on the head are well aligned. The mirrors (= visible reduction of melanin in the first flight feathers) are clear but not too extensive (maximum 60% of the visible length of the first flight feathers and 40% of the outer tailfeathers). Beak, legs and claws are equal flesh-coloured. Depending on the lipochrome and the category, following jaspe canaries in the brown series are recognized: - Yellow intensive (SF) - Yellow non-intensive (SF) - Yellow mosaic mozaïek (SF) - Yellow ivory intensive (SF) - Yellow ivory non-intensive (SF) - Yellow ivory mosaic (SF) - White Dominant (SF) - White Recessive (SF) - Red intensive (SF) - Red non-intensive (SF) - Red mosaic (SF) - Red ivory intensive (SF) - Red ivory non-intensive (SF) - Red ivory mosaic (SF) = Single-factor

The Mutation Jaspe (single-factor) of the Agate series

On the back, the shafts of the feathers and the edges are grey. Between these grey zones the tint becomes lighter grey. The back shows underbroken fine striations. The flanks show clear and well-aligned striations, which converge in the middle of the chest. The striations on the head are well aligned. Absence of visible phaeomelanin. The mirrors (= visible reduction of melanin in the first flight feathers) are clear but not too extensive (maximum 60% of the visible length of the first flight feathers and 40% of the outer tailfeathers). The beak, legs and claws are lightly but equal melanized. Depending on the lipochrome and the category, following jaspe canaries in the agate series are recognized: - Yellow intensive (SF) - Yellow non-intensive (SF) - Yellow mosaic mozaïek (SF) - Yellow ivory intensive (SF) - Yellow ivory non-intensive (SF) - Yellow ivory mosaic (SF) - White Dominant (SF) - White Recessive (SF) - Red intensive (SF) - Red non-intensive (SF) - Red mosaic (SF) - Red ivory intensive (SF) - Red ivory non-intensive (SF) - Red ivory mosaic (SF) = Single-factor
Special characteristics of the Jaspe mutation: 1. The clear visible reduction of melanin in the first flight feathers, also called "mirrors." This feature is also seen in the central part of the outer tail feathers. 2. The head and flanks are clearly striated. On the chest, the striations approach the middle of the chest. 3. The strong dilution in large areas of the primaries and the contour feathers of the wings (called "patrón alaire"). This particularity does not expand to further mutations of colour canaries. 4. The "patrón alaire" is more visible in male birds than in females. 5. The appearance of the Jaspe mutation can not be confused with other existing mutation. 6. The phaeomelanin is not affected by the change in melanin. 7. The colour of  beak, legs and claws are the same as in the classic series. Regarding the lipochrome we can find the Jaspe in all existing ground colours: - yellow, yellow ivory - red,red ivory - white (recessive or dominant)
