Hi,

Last saturday I brought a pair of Cinnamon (or Brown) Double Bars.
In Australia do you have this mutation?
Here some photos:

Ohh fawns! Lol I don't know how to call them in english so I called cinnamon

yes we do have so called fawn boublebar finches in Australia,they were first bred by a freind of mine in SE Queensland.The originals came from wild stock.
They are extremely hard to breed,with fawn cocks proving infertile.The only way i and many others could breed them ,was with a fawn hen and a split fawn cock.the resulting young were all firtile,except for any coloured young cocks.Most breeders purchased a fawn pr and never bred a young one.This mutation is going to disapear in our aviaries,unless breeders use a split cock to their fawn hens.Fawn cocks, in my opinion,are just a pretty bird.

Here we don´t have that problem. Both male and female are fertile just like a normal double bar finch

Hi Luis, i fogot to mention, the fawns we have here are actually cinnamons which makes them sexlinked reccesive.We can put a split cock to a normal hen and produce cinnamon hens straight away the other normal looking young are just that normal. In the nest cinnamon young have deep plum red eyes.
If yours are straight ressive,they are fawns and you want have the problems we have with our sexlinked coloured cocks.Do you know if they are straight reccesive? Cheers Craig [crocnshas]

Hi Craig,

Ours are sex linked too.
I saw few fawns double bars on the nest, and the ones I saw doesn't have red eyes. Probabily are like fawn Zebras, ones have red eyes and others doesn't ... I'm not fully concern about the naming of the mutations in english, but normally the same mutations in diferent species have the same name. For example:
- Fawns - Zebras, long tails, plum headed and double bars - all are sex linked. Here in Portugal we call this mutation "Castanho" (Brown in english). And the Cinnamon Stars, being sex linked recessives, we also called them "Castanhos". Sorry if my english wasn't too good for the explanaition
