No, they probably have a noisy environment, and are losing their feathers due to nervousness.
A cardinal could lose it's tail for many reasons. one of them could be if it got into a fight with another animal or bird. it could lose it tail from being frozen off in winter...etc...
Because your cat is enticed by the bird. My cat often sits by the window to watch birds and squirrels. Tail twitching is a normal activity.
Usually it is not normal i think you should take it to a bird specialist or vet.

most geckos lose thier tail. thier tail always grows back.
I do not believe that this is normal behavior for a bird. It would seem that it is experiencing some sort of distress, you should contact a veterinarian's office as soon as possible to try to keep your bird healthy.
