Need help identifying gouldian

[kheather]

okay...I understand now the df/sf stuff(more or less)!! I like that forcaster for gouldian offspring, thanks

I like that you can see the colors as you pick them.

so if Daynas bird above were a double factor...what visually would be different?

You would see more of a white bib (the area under the beak) and a greater (if not almost total, since he is white breast) suppression of the turquoise behind/around the mask.

This is a DF (though he is Lilac breast)


This is a SF - note the significant difference in color in the blue band both around the mask and under the chin:


Sometimes distinguishing the two is tricky. This is a SF male but the color of his bib is quite light in comparison to the SF above. This is why you really have to look at that color around the neck.


Also - if a male is Purple Breasted and visually a clear yellow you know he is ALWAYS Double Factor. I say clear yellow because some "Dilutes" can be very very light, but they usually have some degree of mottling throughout the back, like a darker feather popped here or there.

Thank you for link, I am still confused...the whole yellow thing...and I have 4 yellow babies LOL!!

One thing here is that yellow females inherit the yellow from their father only (as they also do with black head).

This means that you can never produce a Yellow hen from JUST a Yellow hen. She will only pass the yellow factor onto her sons.

The only way to produce yellow hens (or black head hens) is from a father who is carrying yellow (or likewise, BH).

So in your case, your pastel male can produce yellow hens, and since we know he is split for WB since you produced a WB silver boy, we know he could also produce WB SF Yellow/Blue males.
You'd be able to tell the difference between the two in a nest because SF Yellow boys will have dark heads and dark beaks.. yellow hens will always have pink beaks and light heads (as babies, regardless of adult head color).

These two yellows are both LB SF Yellow/Blue males


This is a nest with two yellow hens, and one SF Yellow male. Can you tell who's who?

You have the best photos and explain things very well.

Another GREAT lesson and pictures as always, thanks Tiffany!

Tiffany you should write a book on gouldian genetics. It would be a #1 seller among gouldian enthusiasts.

[nixity]

Aw shucks.. thanks guys..
I WISH I could write a book that would actually be helpful ;)
I'll stick to NFSS articles for now.. I think I've run out of topics though. LOL

[kheather]

I agree book, plus you have aquired all those hatchling pictures on your site that are so great for learning the skin colors of different color babies....you do have a talent!

Hy guys! I have a white breast male, black head green back male bird. The parentes were also WB but spotless, beatifull birds. This particulary bird after the second molt, shows a very definite purple patch on it's former all white breast! What happened? Whats the genetics to this bird? Can anyone help, please...

[Dayna]

I would say that he is what they call a "dirty" white breast. Lilac breast is dominant over white breast so given that the two parents are white breast he can't be lilac breast.

[marcelo levy]

This bird had initially an all white breast, both parents are WB, what happened, why did it change? Can it be bread? Will its offsprings be WB or spotted as this male?

[duchatinh]

Defenitely a RH WB SFYB male

I have never seen anything like that before. I would say you have one of those "fluke" birds that has a modification. It would be awesome if you could get blue breasted gouldians. If you breed him breed him to another white breast and see what happens

[debbie276]

I've seen that type of breast quite a few times. Sometimes they call it dirty WB and it clears up to all white next molt and others I heard turn to all PB in the following molts. Not sure why it happens though.
