Manvell spoke of an interesting theory in which he states that wild budgerigars could have been the same size as a rosella, if only there had been a constant and rich food supply, and they would not have had to fly the long distances they do today. If only the climate had been less hostile. However, it's only a theory, but it makes sense.

Nowadays, it is thought that the closest relations of the budgerigar are the Neophema species.
The Neophema consist of 6-7 parrot species:
1) The blue-winged parrot (aww, it looks like a little fat budgie!)

7) Depending on the author, the Bourke's Parrot may also be considered part of the Neophema, but unlike the Neophema, the Bourke's Parrot is not related to the Budgerigar.
