During the five centuries that have been bred in captivity, many varieties are obtained and several options for selecting this family of birds. The most prominent are those related to the pigment in their plumage and song, but also takes into account the peak, its position, the curl and shape. There are four basic colors: green, cinnamon, white and yellow. It was in Holland where he led one of the fundamental colors canaricultura melanin today: the agate. Ash Gray was called, and apparently were the first examples of a group of cows born green canary. With the appropriate crosses were set mutation and that achievement encouraged breeders to multiply experiences. More info: Sam Less UPenn. Currently, eight basic colors are considered in the classification of the color of canaries: Agate, bromine, Isabella, black and green (between melanistic color), yellow, white and red (between lipochromes).
With these base colors are almost endless varieties of color and drawing currently showing canaries, both in pigmented (brown or black based) and non-pigmented (lipocromaticos) or which, in its basic characteristic of pigmented lipocromatico add some color, ie hue other than black and brown. Due to the number of crossings that are practiced in this species is abundant chromatic diversity. In 1908, New Zealand, appeared 'white', born of yellow snow, so they are called "recessive." They are birds that are coupled to the color of their feathers, the characteristic that can not synthesize vitamin A. In 1926, hybrids were obtained by canaries red background as the original canary does not have that color in their genetic code. Infertile hybrids were obtained copper-colored, yellow canary crossing with males of Tallinn, lacking the yellow factor in their genetic code. Different crosses over ten years allowed to obtain a factor canaries 'red', which with adequate food, nestlings of canaries have a very bright red color. Already between 1950 and 1960 he performed three new mutations present today in all the color selections, "ivory", "cake" and "Opal." Already in 1963, this time in Brussels, got a new mutation, called factor 'ino.
" His eyes were bright red and although its general appearance was that of a factor canary "pie-Elizabeth 'with some brown. In 1966, in Italy, obtained the first factor canaries with "gray wings," a variation of the cake factor. In 1967 and in Argentina, a new mutation, factor canary "satin", with red eyes. In the eighties of last century, the first specimens were obtained with factor canaries 'Amethyst', called 'central melanin', a variety that is considered official after 1939. Currently, there are both among canaries topaz the "black-brown" as among the "agate." This diversity has made the canary color as the most sought after and valued by bird lovers.
