Hey Teresa, sorry for the delayed response. Yes I know of Sergio. He no longer breeds gouldians though, he specializes in rarer cockatoos and macaws these days.... He was once talked about here on this forum for advertizing "orange backed" gouldians. There was a light that cast a orange/red glowed and it was the concenses that maybe they were a "lighting tricks" with the birds??? He swore they were authenic but that the lighting did make them look more orange. I have a yellow backed gouldian that has developed an orange/red neck so I do believe it is possible. Nothing like seeing it with your own eyes to be a believer
Anyway here are a couple of my pied birds...sorry for the awful pics...still haven't mastered photography 101 and most of the birds are on nest and were a little freaked out by my photo op
Yellow Pied hen born Jan. 2009 and has retained all green spots through moults
Different hen, sister of the above, same age
Different pair, this is a new mate for her this year...hopping for heavier pieds
Last year she birthed normals, sf yellows and sf light pieds
This is one of her youngsters from her last clutch of 2010 (February I believe it was without lokkin at the records) I kept him because he is unique...we will see how he turns out with the next molt
He's the first I have gotten with a mottled chest, this line usually has very nice lilac breast, he has some dark purple, lilac and white feathers...will be interesting to see what happens with his next molt
Here he is with some other youngsters...he's the one with the mottled chest
Here is a link to my first nicely marked hen at a young age, unforyunately I lost her soon after that photo was taken. The topic was given some additional information so I have included the link.
