Parrots are flock animals by nature, and once they feel neglected, they usually resort to squawking as a tool of communication, which often triggers constant screaming if not done in the right way. Different cries can have different meanings:

A little whimper means a good mood.

A croaking yelp means it indicates a fright.?

Gurgling means something like murmuring.?

Chattering means anxious.?

Methods to make parrots stop screaming

Distractions, more toys that parrots like, other such as movies, radio and so on, can be timed every day to let the bird to listen to the radio habit.

Set a fixed time to play with him. Pets are meant to be "pampered", and if they are always left alone, relative bad behavioral problems will arise. Of course, pampering is not the same as spoiling, so don't allow your parrot to spend too much time with you or to go out of the cage freely unless you are sure that you will be able to spend that much time with him every day.

Try to translate his calls, and if he can talk, have a parrot that can learn to talk use his name or other simple greetings instead. If it's harder to learn to talk, such as a golden sun, replace it with a whistling sound.

Enticing with food. When screaming continuously, don't look at him or respond to him, or the next time the parrot will know that this way to elicit a response from the owner. Instead, give a verbal or food reward when the screaming stops.

Don't resort to yelling or hitting, which usually only results in a small period of calm or a larger echo. Unlike people, parrots don't understand punishment.

Covering with a black cloth or turning off the lights can be used, but it doesn't always work for every bird, and should be limited to no more than ten minutes at a time.

Some parrots' continuous screaming is just a way to know if their owner is okay; try training to establish contact with him before he gets into the habit.
