Black-eyed Yellow Kakariki pairings

Hi, would appreciate some advice...What would be best to pair with a cock-bird Black-eyed Yellow Kakariki? Also is the Black-eyed Yellow the same as the Black-eyed clear and is this a recessive mutation?

Thank you.

Hi Hammer,

I think it would be best that an Aussie replies to this question but at least over here in Europe the blak eyed clear or black eyed yellow is a selection of the recessive pied mutation in which the bird is completely marked.

Thanks for your reply Pablo...

If I understand it correctly, if you want black eyed yellows you would be best to breed a pair of yellows together otherwise if for example I put a black-eyed yellow with a pied I will likely only produce marked pieds?

Hi Hammer,

if the yellow birds you have in Oz are rec. pied then your statement is true (over here in Europe the yellow birds with dark eyes -without visible iris- are called goldcheck).
In this particular case it seems that if you pair yellow birds with birds that aren't yellow, you 'walk backwards' as the offspring may not be completely yellow.
I read something about this at Rob Opbergen's website or maybe it was a post in this forum.

My experience is similar, as most goldchecks I bred came from goldcheck x split or split x split pairings, and most of the 'goldcheck' offspring had green feathers or even patches. Only 1 of them was completely yellow.

One example of 'goldcheck' with green patches is the bird in the background (the one in the foreground is a normal dom. pied).

I'm abit confused by all these mutation -names
BEC
Buttercup
Goldcheeked
Black-eyed Yellow
Lutino
golden yellow
etc.
what are they?

correct me if i'm wrong

-Yellow bird with red eyes = Cinnamon/fallow combo (sometimes incorrect called lutino), buttercup???

-Yellow bird with black eyes = double factor reccesiv pied and single-/ or double factor Dominant pied (BEC, Black-eyed yellow?). Goldcheeked/golden yellow is a selection from this mutation combo that have a more golden coulor (due to double factor Dominant pied or simply a darker shade as u can see in the dark/light fallow mutation???)

If u have a fallow/Black-eyed yellow combo, would it look like normal Black-eyed yellow with black eyes?

Any one who knows?

Hi Freddie,

don't be overwhelmed, because in my opinion this subject of parrot/parakeet mutations and genetics is a bit complicated, and even science is still not very developed. With this I mean that even experts are not completely sure of what we have within hands, there is a lot of research to be done.

From what I have read here on the forums and the little things I know about genetics/mutations...

Yellow birds with black eyes (no iris ring): 100% pied bird, combination of dominant pied + recessive pied = Goldcheck

Yellow bird with red eyes: possibly goldcheck + fallow

I can't tell about combinations of fallow + cinnamon as I have never seen them in flesh, but in photographs my impression is that they have a very light green haze, whereas the goldcheck kakariki is a 'banana yellow' , an intense color.

BEC or DEC is an allele of the autosomal recessive ino (NSL ino):

so I think maybe we should not use BEC or DEC to define 100% pied birds.

Buttercup is another 'tricky' name that I have also seen used to define yellowhead indian ringnecks (fallow), but it's not one of the standard agreed terms.

I hope this helps a little bit.

Cheers / Pablo

Hi, thanks for previous info…

Wanted to check on the likely outcome of Pied split BEC cockbird with Pied split BEC hen

I assume they would produce male and female offspring of the following:

25% BEC
25% Pied
50% Pied Split to BEC ?

Hi,

I had to 'cheat' and check it up with gencalc.com
In case of the pied mutation I used DF for simplicity, although this might not be the case.
This is the outcome
