Vomiting is a courtship behaviour: one budgie is showing off how much food it can afford to waste, and a budgie with more wastefood means a budgie with more food it can afford to use on feeding offspring. Thus, a budgie that vomits more is a better mate.
The above answer describes the act of regurgitating food, and it is indeed a courtship behaviour. It is also how the mother birds feeds her young. In regurgitation, the budgie regurgitates food in its crop. When regurgitating food, the budgie bobs its head up and down, stretches out its neck, and opens its beak wide to pass food to another bird.
However, vomiting is another matter. Vomiting is the act of expelling the contents of the bird's intestine, not its crop, and is a sign of illness. You can tell the difference because when budgies vomit, they tend to shake their head from side to side and the vomit sprays as the bird seems to "spit". Vomiting can be a sign of a virus, bacterial infection, fungal infection, parasites or any number of causes. If your bird seems to be vomiting food, rather than regurgitating food, you really should take it to a vet as soon as possible.
This is not vomiting - this is the act of regurgitatingfood. It is a courtship behaviour, and carried out between male and female budgies. It is how the male will feed a sfemale who is sitting on eggs. It is also how the mother birds feeds her young. In regurgitation, the budgie regurgitates food in its crop, and the seed is not properly digested.
