Exactly

It isnt a hard and fast rule... but since the bird is as old as he is, and still doesnt have one something he is masking like recessive pied must be showing

I do have males split for it that still have iris rings The bird you mentioned Susan has a spot on the back of his head... thats another example of how being split for something can show through even though the bird is not visually a recessive pied

This is true for some of my budgies.

thank you all for all this information. I am sorry I have not replied before, but I thought this thread had died a while back and haven't been paying attention. If he is split for rec pied then I must breed him to another with the rec pied gene to get rec pied to show in the outcome right?
Trying to learn genetics, surely doesn't happen overnight.

thats right, you need a rec pied gene from each parent.
