Hi All,

Further to thread:
http://talkbudgies.com/showthread.php?t=77480&page=2

It would be good if you can tell me your view on the genetics of "Dusk" (un-related to "RIPBudgie"'s new "dusk"-genetic type in process of being "WBO ratified")...?

I'll first show her "baby pictures", then (next post) parents...
Here is "Dusk":-
Bird Beak Feather Parrot Wing

Bird Beak Nature Organism Adaptation

Questions are:
- Knowing her mom is a YF T2 Dilute Cobalt Greywing ("Cloudy"), and her father is a dark spangle ("King George")....do you see any spangle in her....(given wing-markings are so light)...

- There may be very faint body colour in the wing markings as well (a possible sign of opaline)...while body colour is definitely diluted....

Problem I'm having is what exactly should I (we) be looking for in the bird's feathers, cheek patches, etc to distinguish such:
- Greywings;
- Dilutes;
- "Yellows / Whites" (I understood these being the same as "dilutes", just old naming)?
- Clearwings; and
- Lightly-marked spangles....

...some of my birds with the above "gene-mixes" really all look very much alike?!

Here are another few with such "gene-mixes":
Velvet (greywing, but know spangle parents!)
Bird Eye Parrot Organism Beak

Sunshine (greywing, possibly "dilute" - but look at the bright body colour?!)
Bird Beak Parrot Pet supply Organism

The latter two are actually "sister" & "brother"...only different clutches...

All your help are appreciated!
Thx,
Jaco dk

...here are the parents of the above "Dusk" girl...

Mom "Cloudy" (maybe she's rather YF type 1, not type 2 - although her babies do tend to "flush" randomly with YF-type yellow wing & body feather markings ...with age that is!...but not into the "sea-foam" green body texture, as the type 2 do..!)
Head Bird Eye Beak Parrot

Dad "King George":
Bird Beak Macaw Parrot Feather

Thx for now,
Jacodk

Dusk looks like an opaline greywing but the picture looks like the colour has been enhanced so she could be an opaline dilute

Velvet has white cheek patches which are often a sign of spangle but the markings are very faint so you could have spangle dilute. I don't think it's double factor spangle

Hi - thx to all...

Nev,
1) May I ask (relating to Velvet), given your response on she being possibly "Dilute Spangle"....would it be the dilute that affect the spangle wing-markings to be "less defined"?...and in this context she might be such "dil-gw, opaline and spangle"...(I've added the greywing, as you've indicated such when I posted pics of her as baby!, whilst Opaline could be correct also from fact that her dad, "Rainbow 1", is split opaline-getting it from opaline grand-mom)..

2) Is it also not possible then...given Show-breeder advice about "the important need to have Spangle-birds in your stud to create vibrant body colour"....(as I've myself experienced thus far) ..that the Spangle brightens-up the body colour vs the Dilute then causing the opposite....

...will it then be correct in understanding that the more "dominant Spangle"-gene in such a "combination" bird - is the influencing factor that results in the "body colour" effect of the "dilute"-gene to be "over-shadowed"...thus a brighter body colour (such as "Sunshine"), whilst still having the diluted effect on wing-markings?

Maybe from your and other's experience such (or other) gene-patterns may become "guiding principles"...to look out for?

thx again,
Jacodk
