Seriously? We talking about the same bird here? This is gonna sound critical no matter how nicely I put it, so take it with a grain of salt as im not out to attack or criticize. But budgies are BIG TIME night fright prone. Be hard pressed to find someone on any budgie forum who hasnt either experienced it with their birds, been scared being woken by it or witnessing it and not being able to calm them (all you can do is turn lights on and wait), or by losing much loved or prized breeding/showing birds with broken necks and other injuries from a night fright crash.
