Signs of an unhappy parrot:

1. Bite the owner. One telltale sign when a parrot is angry is to bite its owner. Even if the owner does not approach them, parrots will fly to the owner and bite the owner.

2. Pecking feathers. When parrots are in a very angry mood, they will continue to peck at their own feathers, sometimes ripping out many of them.

3. Shouting loudly. Parrots are very noisy when they are angry, and their cries are very harsh, which is very different from their usual happy cries.

4. Emotional. When parrots are angry, they have obvious mood swings, and we can tell from their emotions that they are angry.

Methods to soothe a parrot:

1. Play with it. Give it a little more security, then feed it some food, drink some water, etc. That's it.

2. Play some light music. This can alleviate the parrot's fear, but don't make too loud a sound, otherwise it will still scare the parrot.

3. Send to a doctor for examination. Sometimes it may have mental problems, and no amount of comfort will be useful, so at this time it must be sent to the hospital for treatment.
