I usually cover the cages between 8 and 9 every night. As I walk over with the cover the budgies jump to their sleeping spots(swings). I uncover around 8 in the morning and the linnie is always awake but the budgies are still sometimes sleeping.
Mine rise and sleep with the sun. Right now it gets dark enough for them to start geting ready for at 7 - 7:30 ish and then they get up around 6 i think. I wouldn't know as i sleep right through all the noise. I did however get to enjoy watching them wake up once as i stay up all night long
My linnies and parrotlets go to bed around 8-9 when it gets dark and wake with the sun. My upstairs birds (goober and moose) are up with me until 11 at the latest and wake up with me around 8-9 am. They're upstairs and quiet to themselves during the day and nap a lot in the afternoon to make up a little extra sleep.
Mine go to sleep when I go to sleep which is about 10-11. I cover them at 10 and if I'm still awake they will make noises and play quietly until I turn off the lights. They wake up at about 7 and take a nap at 12-1pm
My Linnies go to bed around 9 pm and my conures go to bed in their sleep cages at 7 pm. Everyone is up around 6:30-7 am The Linnies get to stay up later because they take naps throughout the day, my conures don't take naps. Zoe is funny because if I try to sleep in a little later like 8 am, she starts calling out by saying peek-a-boo. She starts out softly as if to say, "Is anyone there?"and gets progressively louder as if to say"Hey it's time to get up, I'm hungry!!":lol:
The only fids of mine who have a bed time are the conures, cause they're cranky little so-and-so's when they don't get enough sleep. They're put in their sleep cage in a quiet/dark room at 8:30pm, and wake up around 7:30am most days. The others are in their cages by 10:30pm most nights.
