Makes sense to me two variations of pastels.Good pick up Tino Anyway nice looking bird Amca.

Sounds good to me, you never stop learning and when you do you may as well give it away.

People get confused between pastel appearance and Pastel genes. The Pastel gene causes dilution of any back colour, so all SF and DF Euro Yellows, pale Blues and Silvers are genetically 'Pastel' birds.

There's a good summary explanation here: http://www.finchstuff.com/GouldianFinch ... tions.aspx" onclick="window.open(this.href);return false; - see the part under Pastel, sex-linked.

have to disagree with the last post.
Double factor is not referred to as pastel around here, it's mainly an American term and that is a yankie website.
Pastel = blue plus sf yellow, purple or white chest.
My two bobs worth

It's an Australian web site and the genetic terms are those recommended by four of Australia's most well known Gouldian Finch experts and avian vets, Ron Tristram, Milton Lewis, Rob Marshall and Terry Martin.

The point is that how a mutation appears and is therefore understandably described causes great confusion when people are trying to get their heads around the reproduction of the various colours. It helps a lot to understand that all of these colours are being created by a single sex-linked gene - the 'Pastel' gene.

(What made you think it was an American site? Americans actually confuse themselves even more by calling SF Pastel Green birds "Dilutes"! What a head scratching time they must have.)

I guess just because of no .au at the end of the URL, plus the fact most people that I know in the west call them dilutes as I have grown to call them, still knowing there is a dilute as a separate gene. Shouldn't it be a sf european yellow back gene then? I never heard of a df pastel before.

OK use lot ive had enough off this all blue back silvers and pastel blue talk use have made me want to get back into breeding these lovely birds now whos up to restocking lol ill post in the wanted section

Well that worked well.

it sure has worked
