In Australia budgerigars are found in flocks. Of course cause it's their native land, but I've heard there are flocks of budgerigars in US, particularly Pheonix, Arizona. Can anyone confirm this? Any other cities with flocks of budgerigars?
We have flocks of feral parrots. Quakers and Amazon's from the top of my head. Feral budgies also live in Florida but don't seem to be a problem with the native birds.
