Ok, I stand corrected.
What I have been calling a Major Mitchel is actually a Sulpher crested.
There are hundreds of Sulphers in the parks around here and they graze with hundreds of pink and gray Galahs. I Could walk up to within a metre of them all before they will fly off in a group. Its quite a site to see. I cant believe those prices. When we were kids and and wanted a bird, we just climbed up a tree in the outer suburbs and took one. Pink and grays and Sulphers mainly. Every kid had one at home. When the babies fall out of the nest you can just scoop them up and take them home (if your afraid of climbing) or the ants will get them. Its funny what you take for granted. People would laugh till rolling on the floor If I suggest a Major Mitchel cost $21,000 Australin dollars (7000 English pounds) in Australia. We just go for a drive in the country, find a flock, climb a tree and get what we want. God, if I lived in Africa, or the Amazon rain forest, Imagine what we could grab in our back yards there.
I will see if I can get some video of The flocks around the city here. If you use "Google Earth" look up Adelaide, South Australia, see how our city is laid out. The CBD is surrounded 100% by park lands. So I have to drive through the park to get into work each day. Flocks of too's mingle and feed with each other all day long.
