blue and gold sporadic squawking

hey guys, So i have a blue and gold female macaw who is about 4 and a half years old. Since i took her in around june, her squawking has gotten a lot better (she was a loudddddd bird when i first got her) but lately she seems really random in her squawking. She can go days without barely saying a peep, yet last night and this morning she hasnt stopped constantly screaming (either that or she talks and squawks). Now, even when i cover her she still talks and makes low noises, but i just dont get what triggers her (i think she is towards the end of molting because she has a lot of pin feathers on her neck). These long squawking periods happen every couple days where she will squawk for a constant hour or more and i have no clue what to do to stop this behavior. i cover her around eleven and uncover her at 10 before i go to class and sometimes she'll be quiet when i leave yet sometimes she wont shutup (my roommates let me know if she gets loud). Is she not sleeping enough? should i uncover her later in the day or put her to sleep earlier? she used to squawk at 8:30 in the morning for a while last month but i have stopped that thankfully.


i could use some advice on this

thanks guys

remington gets a little crazy when he sees a vaccum, mop or broom, if i cover the cage with a sheet he doesnt make a sound...so that's how i have to clean..is there anything "new" around that could be upsetting?

Birds will often call out in the morning and in the evening, in the wild it is their natural way of staying in contact with the flock, before roosting at dusk, and re-establishing contact in the morning, you'll just have to remember, you are now her flock, a proper sleeping schedule would also follow the solor cycle of dusk to dawn, though many people aren't up quite that early leaving them covered till a little later would be fine, 12+ hours of uninteruped sleep is the norm.
