I saw a budgie like this posted on this forum before. But is there a name for this, "thing"? And a little FYI I think I might buy this budgie, I saw it at Petco.
It has green markings in the back of it's head. Is there a name for that? I'm guessing it's fairly new since I've hardly heard about it.
I believe the green markings you are talking about are because of her being Opaline. Many Opalines (if not almost all of them) have the colour going through the markings at the back of their head as well as the usual colour going through the markings on their wings.
