Sleep is important for health

Sleep
Budgies need somewhere quiet, that’s free of draughts, and in winter especially, a blanket over the entire cage. Budgies should get at least 10 hours sleep per night, and up to 14 hours per night if you have a male and female together, as sleep affects breeding. Less sleep and more light means more likelihood to breed.
Male budgies especially, will sing/chirp loudly as a way of saying “all is well”. It is very normal for budgies to get louder and compete with things like TV or lively conversation, especially in the evening when they would normally sleep. They will also have little naps throughout the day, which is quite normal.
