Sorry to bring this up yet again, but I have another question about Yellowface/Goldenface....

 

 

"If Australia has no yf2..then a bright yellow faced bird with yellow all through the wings markings, head, and body (making it a sea green colour) is what exactly? A single factor gf?

So, let me see if I got this right. We (australia) have no yf2. So we only have yf1 (double factor, causing a white face bird, and single factor, which is a cream faced bird with little to no yellow in the body) and gf (double factor, which is as the picture above, and single factor, which is like a yf2, a sea green coloured bird as all the yellow goes throughout the entire body)??"

 

This is correct, according to the genetic experts here. Now, this bird:

 

Was said to be a DF Goldenface. I am not certain but a DF Goldenface when mated to a Normal will have all SF Goldenfaces right? Well, she had a clutch (only one baby survived unfortunately) and the baby was not a single factor Goldenface..it wasn't GF at all. How does this work? She does not fit the description of YF1, single factor or double factor..nor does she match the description of SF GF. But that is the only thing I can think she would be, as her face is definetly a bright yellow and could not be described at cream-coloured at all..and apparently the amount of yellow is different between birds, and she had only a few feathers that were green, so is it possible she is a SF Goldenface with very little yellow? If not, what is she?

Sorry again for bringing the Yellowface/Goldenface up again, but that mutation in particular confuses me lol..

Thanks for any help.

Well a Double Factor yellow face or golden face is a white face bird. Unless it's a green series and then the yellow face is masking the double factor.

 

We do have Yellowface Series 2 birds here in Australia but what we have lost is the Australian Yellowface which is a more buttercup yellow.

 

The photo appears to me to be a Yellowface Series I hen and quiet cute at that.

 

The Yellowface series II has the yellow bleeding into the body causing the sea green effect in the blue series and a yellowy grey in the grey.

 

If you google ParBlue and ParParBlue it should give you the YFII and GFII birds.

Yellow Face type one produces a bird with a light yellow (creamy coloured) face and little if any spillage. Double factor yellow face ones technically dont exist, but i wont go into that arguement right now.

 

Yellow Face type two gives you a yellowfaced bird with yellow running smoothly through the wings, body and tail. It is usually pale, although with any mutations there are some brighter than others due to genetic variance. You can get single and double factor yellowfaces. (You can also get composites, but for simplicities sake i wont go into that either).

 

Goldenface is exactly the same in breeding and appearance (including composite varieties) as yellow face type 2, except it is MUCH brighter.

 

Having said that, your bird does appear to be a goldenface. I would need more pictures to be more sure, but im fairly certain it is a single factor goldenface, probably a b^gyb¹. So breeding it with a standard b¹b¹ blue bird, will only give you 50% goldenfaces like the above bird - b^gyb¹ and the rest of the chicks will be b¹b¹

 

Edit: That bird doesnt look seafoam green? Looks blue in the body?

Jen114 when you understand the yellowface/goldenface genetics let me know... From what I have read there are a few different thoughts on the subject, and all in all I get extremely confused with the whole thing...

Well a Double Factor yellow face or golden face is a white face bird. Unless it's a green series and then the yellow face is masking the double factor. Double factored Goldenfaces are NOT white faced. They are blue with almost no suffusion and an extremely golden face.

We do have Yellowface Series 2 birds here in Australia but what we have lost is the Australian Yellowface which is a more buttercup yellow. We have not lost the Australian Yellowface at all. What do you base that statement on Daz?

The Yellowface series II has the yellow bleeding into the body causing the sea green effect in the blue series and a yellowy grey in the grey.

 

If you google ParBlue and ParParBlue it should give you the YFII and GFII birds.

 

All yellow-faced birds have suffusion of varying degrees, even double factored visual ones and a lot of it comes down to family genetics and variability of the mutation. The problems of identification happen because people wish to pigeon hole the suffusion. You can't do that because of the nature of the genetics of this variety.

 

There is the possibility that the bird is a Goldenface/Yellowface composite. If that is so she will produce a a normal blue offspring. Breeding result can quite often show us what the bird's genotype actually is. Visual interpretation can only go so far.

 

Goldenface single factor

 

 

Goldenface double factor

So then, basically, there is no definite way to tell what mutation they are until you breed them, because it varies so much, correct? Though with yellowface, the yellow is a cream colour and goldenface it is very bright..though that too can change if they are yellowface and goldenface both, and with the single factor and double factor of those...

Yikes. I agree with you JB, the more I hear about it the more confusing it gets..

Even when you test breed them you will still have differing opinions...

I get very confused with all the parblue parpar blue and goldenface mutant stuff. I just go by yf1, yf2 and gf.

I think the bird is a goldenface. I am far from an expert its just my opinion,

Dont worry guys, it not just you. I think its like RIP said, it confuses most everyone and most people just wanna box it in and not go into depth to figure it out.

 

I've done a heap of thinking and re-re-reading and im fairly sure i understand it all now. Its just down to test breeding to see if im right about my understanding.

Cool, I would like to understand that eventually..At the moment I just call them yf1 or yf2, though they probably are Goldenfaces and composites etc. Makes it simpler, though doesn't really help with knowing what chicks they will have if bred..

Well a Double Factor yellow face or golden face is a white face bird. Unless it's a green series and then the yellow face is masking the double factor. Double factored Goldenfaces are NOT white faced. They are blue with almost no suffusion and an extremely golden face. Are you say that all Double factor Yellowfaces and Golden Faces are not White faces?

We do have Yellowface Series 2 birds here in Australia but what we have lost is the Australian Yellowface which is a more buttercup yellow. We have not lost the Australian Yellowface at all. What do you base that statement on Daz? Information from other breeders. Simalar to the Australian Dominant pied. Rarely seen these days and hard to breed.

RIP I have seen many good Yellowfaced Blues and Greys that don't have suffusion at all.
