Smart girl! I have to admit that I am always surprised when people say their birds want to stay up after it gets dark... I've never had a single problem with any of mine. Once they eat their dinner, they immediately go to their roosting perch and get ready to go to sleep. By the time is night and I draw the blinds, cover the cages or whatever, they are all half-asleep (and i say 'half' because some of them respond to me when I give them the usual: "Nite, nite, sweet dreams, I love you" by either saying "I love you" back or making kissy noises -because I also make kissy noises to them).
