A way to describe this kind of mutation the best. The general body colour verges slightly on aqua.

It is easy to remember because it is the same spelling as “crossing-over” which is composed as two words linked with a hyphen. The mutation inherits sex-linked recessive. There is a yellow mutation, which first appeared in France. Simply “cinnamon-ino” will do. Naked bangla. In combinations with turquoise or aqua one refers to it as edged diluted turquoise or edged diluted aqua. The colour of the rump is white.Because the psittacine is unaffected by this mutation, the red of the mask stays unaltered. One addressed these birds formerly erroneously as “American silver cherry” or even “silver”. The mask is unaffected. If we combine a turquoise and an aqua, the result will not be a green bird split for turquoise and aqua, but a bird with an apple green phenotype. The basic type is called pallid green.These birds have red eyes at hatching that darken into deep dark brown after a day or eight. There are turquoise and aqua mutants. As previously mentioned we can expect colour mutations by alterations of eumelanin, psittacine, distribution of pigments (eumelanin or psittacine) and feather structure. Verbreitung: Afrika. Pale headed lutino. The basic type is the cinnamon green.Cinnamon green, cinnamon D green, cinnamon DD greenCinnamon turquoise, cinnamon dark turquoise, cinnamon double dark turquoise Cinnamon aqua, cinnamon dark aqua, cinnamon double dark aqua(top)In this mutant this is also an alteration of the colour of the eumelanin. The chance on crossing-over between cinnamon and ino is 3%. The inheritance is also recessive. What do you think about it?

The ten lateral rectrices, are green with a red central region, which gradually gets narrow, from the exterior to the interior; there is a black band by the third quarter of its length, the apex is azure.

Although these birds have a dominant inheritance, it is hard to say whether there is a clear difference between SF and DF birds or not.The basic type is pied green.Pied turquoise, pied dark turquoise, pied double dark turquoisePied aqua, pied dark aqua, pied double dark aqua (top)The recessive pied mutation originated in Australia and shows an almost completely yellow bird. When we mate such ‘pallidino’ cock to a green hen we can expect pallid hens, ino hens, green/ino cocks and green/pallid cocks. Not only the clear red eyes are typical for this type of fallow but also the greenish shade at the lower abdomen. The mask stays unaltered because the mutation does not affect psittacin. Eumelanin is almost absent in the legs, toes and eyes and therefore these birds have pink legs and red eyes. These are colours that verges on blue but it is not pure blue.Other psittacine mutations are orange face and pale head altering the colour of the psittacine and also opaline extending the psittacine on the head.

(top)In an aqua bird the yellow psittacin is reduced by approximately 50%. The DF birds are the most wanted for shows. In roseicollis this mutation is sex-linked and we refer to it as SL ino.

Only the wing coverts and flight feathers show the edged effect. When the first lacewings arose, one did not know nor understood that it was the result of crossing-over. Capital letters are used to indicate the start of the mutation: Aqua and Turquoise) The AquaTurquoise type is not in demand in the BVA (Belgian Lovebird Society) nomenclature because it is a combo, however, it is an excellent bird for breeding turquoise and aqua birds. These names should be abandoned as much as possible. Combined with a green bird this will result in a pure yellow bird, the legs are pink coloured and, typical for this mutation, red eyes. Until recently the name isabel was used for this mutation, however, it turned out to be unsuitable for this species. The The basic type is the lightgreen bronze fallow.Bronze fallow green, bronze fallow D green, bronze fallow DD greenBronze fallow aqua, bronze fallow dark aqua, bronze fallow double dark aqua (top) Almost equal to the bronze fallow but there is some difference. RobertAnictRobertAnict If the reduction is about 90%, like in dilutes, the colour will be pale blue. Split birds can be recognized in most cases by a pied spot at the inner side of the thighbone. If we mate such bird to a wild type bird, all offspring will be SF dominant pied split recessive pied. In such bird the yellow psittacin is completely absent. The young leave the nest when five or six weeks old and still go on in being nourished by the male, while the female starts a new hatching. Erstbeschreibung durch VIEILLOT als Psittacus roseicollis, 1818.

However, in roseicollis the matter is different because a genuine blue mutant does not (yet) excist in that species.

(top)The best known psittacin mutant is the blue coloured bird. A blue mutation occurs in both the wild and in captivity, although it is not particularly common. Please try again.
