What colour are your green budgie's longest tail feathers?
Looking at his body colour, I think he is a grey green normal budgie and if so his tail feathers should be black in colour. If they are dark blue in colour, then I'd say he is an olive green normal budgie.
Your other budgie I believe is a cobalt violet opaline.
RIP sweet Tito (Summer 2008 - January 17th 2013).
You are missed and never will be forgotten.
