yellow backs take two

[gomer]

Aussies or Euros ?????

Euros or yellows they are very spectacular.
I especially like the bird in the second to last pic.
The last pic it looks like there is yellow and red on the head.
Will have to do some GGF work.

Edit
got the pics mixed, favourite is the third to last, second to last is the one that looks red and yellow on the head

I would say on quick inspection they are Aussie Yellowbacks but you got me wondering with those last few photos showing blue around the head. Do Aussie Yellows have this? I thought they are meant to be devoid of any dark pigment leaving only red and yellow. So if I had to say I would say most likely Aussie Yellows but possibly DF Euro Yellow White Chested Cocks and Euro Yellow White Chested Hens.

What's even more weird (to me) is that I have 2 Cock birds that were sold to me as Aussie Yellows but 1 of them has the blue around the head. I would like to get this cleared up too!

See the last pic on this page: http://users.skynet.be/fa398872/engoulm41.htm

This bird is classified as a Red Head White Breast Single Factor Pastel Green which looks exactly like the 4th last photo you posted. All very confusing!

Ive just got a poster from the USA that has all the gouldian mutations on it and the one that looks like the pic I like says
"green suffusion, white chested yellow head"
The poster comes from Belgium originally I think.

Dunno poop from clay when it comes to Gouldians but I do know they are awesome looking birds .

Top Six photos possibly Australian yellow (recessive) First photo looks like bird carrying fowling on the back which is found in some birds. The rest of the photos I would say European yellow (sex linked). That would be my guess!

The top six birds can you tell me anything about their breeding. Because Australian yellow paired to normal bird will give you splits. Normal looking bird with possibly a white bib or spot on back of head but not always. European yellow D/F paired to normal should throw all SF birds in the white chest variety as shown in photos

When I got them approximately 4 years ago.I put yellow to yellow the first season to get yellows w/b I only had maybe 3 pr they were from different sources.Then the next year i started putting some yellows (mainly all DF cocks or yellow hens) to green back w/b.And got both green backs and yellows no dilute backs.I turn over the breeders every few years keeping the offspring.So the young from the previous year are now the breeders.This year out of the breeding prs Yellows and greenbacks w/b.I have only yellow backs.Still being either single or double factor cocks and yellow hens.A couple of hens are lemon yellow shown picture one.And the rest are a deep richer yellow.Still no dilute green backs have been breed I have never in 4 yrs breed a dilute backed cock bird.

Maybe my greenback w/b are now all splits ?
I will have a closer look at the green back w/b later next week when i have time.

I am with cranberry, if i have Euro Yellow gomer my hens are a dirty yellow back yours definately look like poorly coloured Aussie yellows with the slight fleck of green feathers. Gomer mine i would say look like almost a mustard colour on the back not dark but yours still has a crisp yellow.

8th and 9th photo looks like sf cocks ( dilutes) but because the white breast is present the back feathers appear yellow. So if u paired yellows to purple chest normals u would get dilutes with a green back since the white chest mutation does not come into play. Hope that kinda makes sense.

[Bgould]

Fully agree with Misso. Dilute (s/f cocks) will show if you breed back with purple chested birds.
