RIP .

 

could you please please answer the following questions.

 

1. Does my blue budgie have opaline or opalescence or split for opaline???

the pictures above i hope will help

 

Based on the pix you have provided and my own experience I really don't see Opaline or 'opalescence'. The areas of feather that appear to resemble opaline are simly feathers modifed through the action of the particular pied gene involved. The flight feathers being comletely 'pied out' has also removed evidence of the wing mirror typical in Opaline in Psittacine species. The tail also shares this problem. The 'opalescence' look in Dutch Pieds is another action typical of these pieds and is know as 'frosting'. This frosting varies considerably from almost none to 100%. It is quite variable and the mechanisim of inheritence is unknown. In the 90's I was participating in a study of pied markings in Dutch Pieds but I do not know if this study is still active or know of any results.

 

2. Is mortimer a dutch pied or an australian pied, and what does this mean?

 

Based on the marking type (grizzling) area of pied markings (tending towards top of body) and that the cere is blue (recessive is flesh) I belive it to be a Dutch Pied. All I would like to see now is an iris ring. Keep in mind though that there is always a possiblility the bird is a composite of Aussie Pied and Dutch and in colony bred birds with different pied types flying around it is always possible.

 

3. Are both these mutations dominant over normal?

 

Yes they are but have a variable penatrance. It is possible for abird to be a pied and yet show such little penatrence that the bird can appear as a normal.

 

4. What type of YF does he have?

 

As I can only go on the pix provided it looks like he is a Yellowface single factor Mutant I.

 

here are more pictures to help you:

 

 

 

 

 

see i learnt well rip lol

 

it just happens that i realised when talking to rip one day about goldenfaces that i had learnt everything i know from her to do with all mutations of pieds and yf , parblues extra

its such a small world

and such a pitty that sight got shut rip it was a perler and very easily understood and detailed info

thanks RIP !!

so he is a dutch pied with NO opaline! thanks

 

so the pied mutation was playing a trick on me, making me think it was opalescence, but it was just 'frosting'

which is typical in pieds!

 

got it! thanks again. now i know for my genetics when i breed!

AB please read what I wrote carefully. I did not say all pieds have frosting. Only Dutch show this characteristic in the normal version of Dutch Pied. Normal Aussie Dom Pied markings are exactly the same as normal looking birds. I never bred Opaline into my Dutch Pieds because I did not want to lose the uniqueness of that variety plus also not make identification harder due to 'opalesence'.

 

Here are some pix for you.

 

This guy is a double factored Dutch Pied he is also a single factor Violet Mauve.

This photo shows only the back view but you can see a small amount of frosting.

 

 

This picture is a son of the bird above. He is a single factor Dutch Pied Olive.

It does not come up on this picture well but he showed only three pied feathers on the back of his neck. If you look at the barring on the back and side of the neck, down through the V area and the wings you see the amount of alteration and a small amount of frosting evident. This some people confuse with Opaline in these pieds.

 

 

This hen is the sister to the above bird. She is a single factor Dutch Pied and also single factor Violet and a Dark Green. She shows only a small amount of pied markings.

A small amount of pattern disturbance and frosting.

 

 

This bird is a single factor Dutch Pied Cobalt. He is not related to the others above and showed no. From memory he never produced any chicks with it. He was also a hugh bird something like 9 ins long.

 

 

The last bird I had purchased and never bred from. A single factor Dutch Pied Grey. He shows a great deal of frosting. This picture does not do him justice.
