I just checked your website and we should be honored to see her before she is shown on your aviary's site!

Gosh - how unusual! She's beautiful! :wub: I'm not really up in breeding, but just wondered why she is called a Lutino? I thought Lutinos were yellow (thinking about budgies)? Or is it a description of a lack of pigment? :blushing:

Lutino refers to a mutation in which there is a 100% elimination in the production of eumelanin. Because the psittacine is unaffected by this mutation, areas which contain psittacine (red) stays unaltered.

The blue areas on a normal dusky pionus is the result of a lack of psittacine, which creates the blue colration in those areas. With a reduction/elimination of eumelanin as well caused the lutino gene, those areas end up white. In normally green parrots (such as budgies) these green areas contain psittacine, so when you take away the eumelanin, you're still left with the psittacine, which is why you see the yellow.

I see! Thank you very much for taking the time to explain it so clearly. :thumbup1: Very interesting! So when you say you are hoping it is a sex-linked mutation, do you mean that any female off-spring might be Lutino too?

Sex-linked is a mode of inheritance. It means that the gene responsible for this mutation is found on one of the sex chromosomes. For example, in humans each person contains 23 pairs of chromosomes. Of the 23 pairs, one of these pairs determines the sex. (XX for females and XY for males). This is the same with birds (however, the symbols used are different). So when a mutation is said to be sex-linked, it means that the gene for the mutation occurs on one of these sex-chromosomes.

Such mutations are quicker and easier to establish and require minimal (if any) inbreeding in order to establish. A male from a pairing such as mine (a visual female paired to a normal male) will produce all heterozygous male offspring (i.e. "split"). One of these heterozygous males paired to an unrelated normal hen will produce a percentage of visual hens and a percentage of heterozygous ("split") males. While "quicker" to establish, with the larger parrots, the generation time of course makes it a rather long process to establish a mutation.

(Note: In birds, the case is the opposite than it is for humans, a male bird is ZZ and a female bird is ZW (means the same as it does with humans, only the symbols are different for birds)

Hope that helps.

I must say, I feel pretty privelaged! :thumbup1:

In the first picture, can we say that the colorations are pretty close as to how she appears in person? I would be interested in some pictures using natural lighting once you get a chance!


Not to take the light off of Peaches, but a quick question for you Ralph.... do you know anything about a potential pied mutation in nanday conures?


Fuzz, genetically she is a lutino, as Ralph explained. Whiteface cockatiels and whitetailed african greys are genetically blue by the same standards as Peaches is genetically a lutino, regardless of the fact that she does not appear yellow, nor do the whiteface cockatiels or whitetailed greys appear blue. There's also blue galahs, but I don't know where the image is... and it's not one mutation I'm crazy about (although it's not a good image, either).

Have you been successful in getting any more lutinos out of the breedings?

Whoops to that. I definitely spaced out and didn't look at the time stamps.
