History of Nero Perla :

In 2015 a new appearance in canaries – currently named NERO PERLA was discovered by the breeder Carlo Maria Nobili in Monza/Italy. From the pairing of a White Dominant Onyx canary & a White Dominant Black canary the breeder C. M. Nobili noticed a phenomenal result in the first clutch.
One of the hatched chicks had a light-skinned appearance. After the first feathers grew, this nestling pointed as a new colour variant in canaries. At this time, it was not yet clear whether it was a real new mutation or just a modification. At the second breeding round, three light-coloured, same to the first appearance, and one still a white black onyx canary were the result. And in the third and last round of the season 2015 C. M. Nobili got four white black canaries and one black onyx canary as result. In total 13 offsprings, of which 4 were black onyx blacks, 5 white blacks and 4 same offsprings (2 males & 2 females) with an unknown appearance, later named as NERO PERLA CANARY

Another phenomenon was that both parents are from in the ground colour white dominant, but in this case a Lethal-Factor was not discovered. All offsprings are White dominant in ground colour with a good health, the best preconditions to start a controlled breeding in the next breeding season. And finally after the following breeding seasons 2016 & 2017 C. M. Nobili was able to prove that “Nero Perla” is a real mutation with an autosomal recessive inheritance.
After the breeding season 2017, a proud stock of 58 mutations can be counted. Also some darker specimens occured, which are currently named as “Pearl Type 2”. The Pearl Type 2 shows a more marked pattern. Currently there are two colour variants:
° Pearl Type 1, with a lighter melanisation (first occur in 2015)
° Pearl Type 2, with a darker melanisation (first occur in 2017) In fact, these results were not expected.


What are the Characteristics of the mutation Nero Perla so far?
1. Currently the Nero Perla mutation occurs in the black serie. The markings and striations are reduced to a minimum but are still perceptible in the reduced and dispersed melanin areas lying between the striations. This creates an all in all pearl-grey colour, except the tips of the flight feathers (wings and tail) which have normal dark melanin appearance.
2. A great difference by far from all known melanin mutations and thus a unique feature is the distinctive phenotype of the mutation Nero Perla. The nestlings have blue eyes, but darken with age. This mean as adult the eyes appear dark.
3. The oxidation of beak and legs are clearly black.
4. The underflue appears grey.

5. A further feature is melanin colouration around the beak, like a mask, yet not determined by sexual dimorphism, such as in mosaic canaries.
6. In newborn nestlings occurs a depigmentation, making them similar to lipochrome canaries with a white birth plumage and skin. Currently (2018) the mutation is not yet recognized from the Confederation Ornithologique Mondiale (C. O. M.)

Because of the autosomal recessive inheritance, the following results are to be expected in the following mating:

1. pearl x pearl = all pearl
2. pearl x non-pearl = all non-pearl
3. pearl x non-pearl/split for pearl (male or female) = pearl and non-pearl/split for pearl (male or female)
4. non-pearl/split for pearl (male or female) x non-pearl/split for pearl (male or female) = pearl and non-pearl

Currently it is known that there are no intermediates between the Pearl Type 1 and Typ 2. So, the Pearl Type 1 can reproduce a Pearl Type 2. But about the whole inheritance of the Nero Perla mutation further facts and experience must be collected, especially about new the Pearl Type 2. Also the transfer of the mutation is in progress and maybe already in the next breeding season we will see four classic pearl types. As a matter of fact, there is a lot of excitement present and we waiting further reports about the new canary mutation “Nero Perla”.

Udseende:

Undersætsig og kraftig, noget større end en gråspurv. Det sorte, kegleformede næb, den sorte kalot og den, i flugt ofte synlige hvide gump er iøjnefaldende selv på lang afstand. Hannen har en lysende rød underside, mens hunnen er blegt rødgrå.

Stemme:
Dompappens kald er nemme at efterligne, ofte hører man et melodisk, blødt »djy« eller »vyp«, eller et lavt »byt-byt«, idet dompappen letter. Sangen er derimod sjælden at høre, da den er meget dæmpet. Det, man hører, er en fløjtende og kvidrende strofe, der i højere grad minder om en bugtaler end om en sangfugl. Disse sange kan høres hele året, og kan have betydning for både par- og floksammenhold.

Tilholdssted:
Træffes i nåle- og blandskove, undertiden også i parker og haver, i skovbryn og på kirkegårde.

Adfærd:
Dompappen er ikke særlig sky og lader sig derfor nemt studere. Som oftest lever dompappen parvis, om vinteren slår flere par sig sammen til en lille flok og strejfer omkring. Fuglene ernærer sig især af knopper, og er derfor ikke afhængige af foderpladser. På mange fodersteder viser de sig regelmæssigt, men er ikke så begejstrede for andre. De lader sig ikke lokke til foderbrættet af andre fuglearter, men reagerer først, når en af deres egne har opdaget en velforsynet foderkilde. Dompappen er, i modsætning til mange andre fuglearter, udpræget fredelig, men på foderbrættet kan der alligevel blive en del kamp mellem fuglene. Hunnen har da den højeste rang.

Foder:
Dompappen ernærer sig først og fremmest af frø fra træer og urter; den har en særlig forkærlighed for blad- og blomsterknopper. Den bør fodres med solsikkefrø, tørrede bær, hakkede nødder, grovmalet korn og færdigblandet fuglefoder.

EU melanin er den sorte melanin og PHÆO melanin er den brune melanin og de sider forskellige steder på fuglens fjer som kan ses på billedet. Når man kombinerer dette billede med farven på fuglens øje og farven af dunfjer, kan man hurtig bestemme hvilken slags farvekanarie er der tale om.

3 guld medaljer og 1 sølv blev det til. Jeg er meget tilfreds, med hensyn til at jeg har mistet næsten alle unger fra kuld 1 pga sort punkt.
Fik en del fugle sent på året (august) og der var ikke tid til at farve dem godt nok og udstille. Håber næste avlesæson vil blive bedre.

Brun pastel elfenben rød mosaik T1 (3 bedste rød mosaik hun – 92 points og guld).

Brun pastel elfenben rød mosaik T1 (3 bedste rød mosaik hun – 91 points og sølv).

Sort pastel rød mosaik T1 (7. bedste rød mosaik hun – 91 points og guld)

Brun rød mosaik T2 ( 91 points og guld).

Udover dem fik 2 fugle til 90 points.
