If you have the right conditions for them, they are unlikely to makemuch noise. However, that means that they have to be in a silent room with no light getting to them. If they have those elements, budgies are unlikely to make much noise at all. Budgies will only make a lot of noise if they are frightened. Other birds such as parrots, will be pretty loud at dawn and dusk, but relatively quiet at night. So, are pet birds loud at night? That all depends on the individual species.
