Green series birds can mask a yellow face character,but they can carry both yellow face and blue as a split at the same time.
A green series bird CANNOT carry yellowface and blue at the same time. The yellowface genes are multiple alleles and as such a bird can only carry two genes at the same time. A green bird can be green/yellowface or green/blue. It's that simple. The bird that prompted this thread is a single factor Goldenface.
This is how I understand the YF mutations to be, but might be off the track here though so if someone has a more definitive answer please fill me in!Goldenface = Australian Yellowface - single factor produces strong yellow pigment and after first moult, strong suffusion through the body colour producing an almost green look. Double factor gives same strong yellow pigment with much reduced yellow body suffusion - stunning YF birds.Creamface = English YF - single factor produces light greamy yellow face with some body suffusion which is usually covered by body colour producing a softer slightly aqua colour in skyblues, in albino's, white DF's and white lacewings a soft yellow colour is evident over the entire body. Double factor does not show any yellow face and appears the same as a normal blue.Cosmo appears to be a single factor golden face (or in my book an Aussi Yellowface).
You forgot the the Yellowface Mutant II - The yellow is paler than the Goldenface and is similar to the Yellowface Mutant I. Single factor birds shows suffusion after the moult same as the Goldenfaces but not as heavy. Double factored birds show less suffsuion.
This is a goldenface, note the goldenface has gone into the body and made it even darker.062017.jpgI take back the goldenface. I beleive it to be a yf2 after reading Barrie shutts mutation page.
That photo of the Goldenface I believe has been tweaked to enhance the yellow thereby not making it an accurate representation of the variety and therefore should not be used to evaluate another bird.

Here is a photo of a golden face I once had from Wilma Bunter ( well known for her golden face line ) . This photo has not been enhanced in any way. Hope it helps.

Very nice double factor Goldenface their Kaz. At least that is a photo of what it should look like.

 

The picture I have posted is of a composite Goldenface-yellowface Mutant I

So how can you tell the difference between a YF1 and a YF2? Other than breeding results that is........ what are the visual give aways between the 2. Golden faces (Aussi YF) is pretty easy to determine but I've never been able to spot a difference between birds currently on the bench (unless they are all YF1 I suppose).

Has sonny had his first moult yet?

If not then yes its possible he will moult into all new feathers.

 

I'm not sure but he probably has since he is between 3-5 months old, he is going through a molt right now but I don't know if it's his first of not.. I don't know if this helps but his mask feathers are a brighter yellow than the yellow on his wings.. Here's a picture..

 

My brother says he looks like buttered popcorn lol ..in this picture his beak looks a little more orange than it really it is but all the other colors are pretty accurate.

My first thought when I got him was that he is a YF2 cobalt dominant pied.

Yellowface 2 and goldenface - there isn't a big difference.

 

although in one book they give the name goldenface to a parblueblue - meaning an offspring of a parblue (yellowface) and an blue. they tend to have a deeper yellow in their faces and get more yellow bleeding into the feathers.

:wacko:

 

Whoa... I can see that the answer has been given a number of times, but I am more confused than ever!

 

There are probably so many different things about budgie genetics that I should know first before I try to understand the YF/goldenface thing.

 

But just to even clarify:

 

- Can I even know whether Cosmo is YF2 or goldenface?

- If so, how can I tell which one he is?

- Would everybody agree with this classification?

 

 

Cory - your budgie is gorgeous!

- Can I even know whether Cosmo is YF2 or goldenface? yes

- If so, how can I tell which one he is? with that strength of colour on the face i would say goldenface would suit. the reason people stated only yellowface before was because he was a baby and still had the softer tones of baby feathers.

- Would everybody agree with this classification? do you all?

This was taken from Barries website::

I dont know anything about the goldenface so it was not me who said that. I'm just going off of barries website. That picture is also from barries website. Maybe you should email Barrie and ask him to correct it.

I agree that Cosmo is a goldenface...... sorry to confuse the issue ;)

 

I get the goldenface v's YF as the goldenface is a much stronger yellow and strong suffusion makes the bird look almost green but i've always been a bit stuffed with the mutant 1, mutant 2 thing with the YF's - there is so much conflicting information when you do research on yellowfaces........ sigh.

Thanks krosp, Cosmo is gorgeous too, way gorgeous ^_^ And I'm with you.. I'm more confused than ever as well lol

Wow that is all so confusing! so what is Sonny a yellow face type 2?

Sonny is the YF dom pied pictured earlier right???

 

If so I would definitely say goldenface. The cobalt on his body is turning that sea green colour and the yellow on his mask is really deepening as he moults.

he is a yf2

cosmo is

he is just a par par blue not just a par blue ask rip budgies for explanation on that one its due to the genetics of breeding i understand it now took me 3 months though and can not explain it i just reconize the diffrents now its helped me heaps with my yf breeding and i have golden face and yf2

ask rip he may like to extend your confushion lol

This is sonny:

Sonny1.jpg

As you can see in this picture the yellow on his mask is way brighter than the yellow on the rest of his body and he has random patches of green on the cobalt part of his body as well.

 

I got really confused because I have a Yellowface type 2 hen, here are some pictures:

Cielito1-1.jpg

 

Cielito2-1.jpg

The yellow on her mask is the same shade as the yellow on her body and it also looks way different than Sonny's..

 

So would Sonny be a goldenface then or just a very bright YF2?
