In canaricoltura color canaries blacks until recently known as brown-black, are those from both the phenotype and genotype both in terms closer to the ancestral Serinus. This similarity should be taken with caution because the selection process took place over the years has moved away from the canary black cousin of the Canary Islands in a net and obvious. In this respect, particular importance is the decision of our Technical Committee, if I am going back to 1997 from Standard to eliminate the presence of pheomelanin canary giving rise to today's monomelanici, that canaries with only eumelanin. Hence the official name change from black-brown to black, I do not agree that name because the total depletion of phaeomelanin in the canary seems utopian undertaking. In this paper, aimed primarily at beginners, I will speak of the canary black detailing the Standard and selective techniques designed to create a strain value. According to their variety the blacks are divided into:
- Canary yellow, black and canary yellow ivory black
- Canary Canary black red black red and ivory
- Canary Black Canary Black and white dominant recessive white
The distinctive feature of these canaries is represented by oxidation dell'eumelanina black will need to speak to the best interest of feathers, feet, nails and beak. The melanins affecting the plumage (EU black and brown traces of EU) contribute to the formation of the so-called design that takes different names depending on the part of the mantle involved, standing in: streaking, vergature, markings and mustache.
Although all parts of the design of a canary black are important for its authenticity, particular importance are the streaks that affect the head, back, chest and hips.
streaks
leave from the front and back stretch for all the initially thin on the head, but it became considerably wider on the back. To be fit for the standard to be long, without interruption, and as large as possible. With regard to the thickness of the stripes should be pointed out the interference of the type category, in fact, blacks and especially the mosaic frosted streaks show clearly larger than the blacks, who owned a banner closer rarely can show very large designs.
The vergature
instead represent the design of medium and coverts are similar to the comma facing the back.
Markings
cover the flight feathers, coverts the helmsman and the primary interest almost entirely, except for a thin peripheral edge affected by lipochrome.
The mustache
typical Serinus whiskers are similar to present at the jaws and is particularly evident in males.
These four forms of drawing as described above will give the maximum oxidation, which will show a very heavy black and brilliant, moving away from a ground which is evident traces pheomelanins. In this regard the presence of pheomelanin is easy to identify in a frosted or in a mosaic, this being brown in color, the same argument you can not do because of the intense mixing with the relatively lipochrome makes it difficult to visual perception. To overcome this problem the novice should pay lipochrome much attention to the canary in question, making sure it is a very bright color and lit, warm colors in black and straw-yellow as they are unwrapped unwrapped those canaries that have a lipochrome tending to brick red in black. To underline in this respect is the sexual dimorphism, as females usually show signs of difficult pheomelanins grubbing, consequently when we are faced with a female black canary necessarily looked at with some tolerance.
To switch to selective techniques, which could be a useful strain of blacks, we must highlight the major flaws that morphologically this canary away from the standard expected from the National Technical Committee.
To this end, we begin to not take all those farm animals which may be broken or too thin design. In relation to this rule must be extremely selective hard fact that draft too fragmented a player will inevitably be reflected in almost all the children and then will be hard to eliminate this defect. Then keep only those that have the long and wide stripes.
A different but should be done for the oxidation, in fact, if the standard provides paws, claws and beak very steeped in black must take account of the phenomenon known as "Black Leather". This event occurs when phenotypic a selection pressure is applied disproportionately in favor of those most blacks, but in addition to affecting the morphology excess of the hormone responsible for the formation dell'eumelanina black canaries usually produces sterile and constantly changes. To not run into that problem is always wise to apply the principle of compensation, matching a person with a highly oxidized making the skin and corneas share a little 'clearer. Last, but not when it 's important is the choice by the breeder, the subjects without pheomelanin except for females as described above must be observed with some tolerance because they show evidence pheomelanins difficult to eradicate.
