Birds will have mood swings just like a human will--in response to something that bothers or ails them. It is a barometer by which to gauge your bird's health. In this same way your bird may be trying express a want or need. But. what are the signs and what do they mean?

Feather Plucking.
Birds will pluck their feathers or chew their own legs for reasons such as: stress and mites. Stress can cause the bird, if it persists to disturb, to pluck until it bleeds. The way to soothe the bird is to remove the loud noises and create a more serene environment for the bird.
Mites should be treated by the veterinarian.

Biting can be a sign that your bird feels neglected. The bird is expressing to that it feels left out of your life. If you play with the bird more, in a couple of days it will be back to normal.
There is also the possibility that they perceive a threat to you. Your bird has likely chosen you as its mate. Therefore, anything that the bird perceives as a threat to you and your well-being he will want to attack.
Most times it will only be hormone change. It should pass, and everything will go back to normal.

Vomiting is a little more serious sign that there's a problem. Vomiting can be sign of distress, disease, or extreme stress. Now remember that regurgitation is a natural behavior in birds. They bring up any food that is not entirely digested. Vomiting on the other hand is when the bird may vomit on itself or across it cases. It will be more sloppy and projecting.
