Hi all. I don't know this birds history other than it came from a deceased collector. I felt sorry for it in a pet shop a few years back. I've suspected its a green singer, though it was sold as a golden song sparrow

I am not sure it's pure as it does not look like the regular GS? It's also been suggested it could be a greater green singer as the necklace etc does not match up to normal green singers. Could it be? Could this be a hybrid?
There was a pair originally. The male had very distinct head markings and was a very rich clear yellow chest much like the regular GS. He had a beautiful song.
This is the hen. I've pretty much established it is a girl and would like to, if I can, get a mate for her, but I want to get the correct one (if she is not a hybrid).
She does sing rather softly, but nothing like the males song.
