Yellow Tip Blue Gouldian

[Blue Cuban]

The Blue Gouldian is a favourite of many but when it starts to display less sharper colours like Red & Yellow heads I for one don't find them as attractive but still beautiful in their on right.

Like many I'm always thinking of new combinations with existing colours and one of those combinations is a black head white breast yellow belly blue back.

Considering how the blue mutation reacts with yellow I got it out of my head until I found these pictures which has renewed my faith of it being possible.

The yellow can be seen in the beak (I assume its genetically a yellow head) and 1 small patch in the belly.

Hi Blue Cuban,

I could be wrong but I thought the YTB came in all head colors in the Gouldian...I'm happy to be correct if this is not right. It is also my understanding that the YTB is also recessive so it is plausible it can appear with any combination of recessive colors...I'm surprised it hasn't become more prolific in the blues than is currently the case.

Nice bird

Cheers
Paul

Sorry to throw a spanner in the works but that bird looks like it has been touched up with the yellow as it is not genetically possible and with the amount of yellow on the bill.
Paul,YTB does not apply to red headed gouldians,only BH split to yellow and YH birds. Cheers Craig

Hi Craig, touched up or not, can you explain why it isn't genetically possible?

Cheers Ian

The yellow-tipped birds are both genetically black-headed AND ALSO genetically yellow-headed.

Scientists agree generally that the original Gouldian finch was probably red-headed. In the wild, two mutations have become established as part of the natural population; firstly, a sex-linked mutation that smothered the red head with black produced the black-headed; secondly an autosomal mutation appeared that converted the red head (and Beak tip) to yellow. Hence, there are two pairs of genes (alleles) at play.

The yellow-tipped black-headed bird is a combination of the two wils mutations referred to above.

The blue or parblue mutation reduces the amount of yellows and reds produced therefore a yellow tip, even faint, would be very strange indeed.

Hope I've not produced too much mud in the waters here!

It does look to be a fake. Although, just a thought, but could this be somewhat like the yellow face blue budgie mutation?

Craig a touch up is always possible with out seeing the bird in feather.
I have contacted the owner for more information and waiting on a reply.

As for being split to yellow head it's like being split to blue there is no tell signs. The only reason a black head yellow tip bird exist is because the the recessive yellow gene paired off with the co-dominate black head gene and or the red gene doesn't exist.
The fact any bird has a yellow tip establishes it is genetically a yellow head not split.
From my little experience of breeding for yellow heads this is my take on it and I could be wrong and happy to be proven other wise.

I do hope that the owner of this bird will reply to me with more I formation and pictures that I will share with you all.

Just like Craig it is my understanding that yellow on a blue bird is not possible.

Rich.

Maybe its colouring of a food offered to the birds or something added to the drinking water.... will see what the owner says

[TomDeGraaff]

Perhaps someone else might be able to shed light on the black-headed/yellow-headed relationship. The yellow tip is NOT an indication of either split OR "co-dominance".

Also, if there is any yellow on the bill of this bird then it again indicates the blue mutation to be a parblue.
