@delishtreats, Yes, our three parrots do make a great deal of noise, but they can be sweet and silent as well. They definitely have their own cycles of sleep and awake, but we control that to an extent. Birds natural rhythms are usually based on light conditions and sun locations, however, We help our birds have good sleep times by putting them to bed at a set time each night and covering their cages.
Gandi is like a typical 3 year-old in that after everyone is put to bed and settled, he will call out to me in a quiet voice and ask to come out again. I know it's probably not a good practice (just like with children) but I usually get him up again for a while for some one-on-one time with me. This is when he likes to play in the kitchen with Mama.
