I recently saw that my cockatiel has somewhat like a dark circle around one of her nose. I am worried that it might be that she hit herself. Down below I posted first the picture of her black nose and the other is the other nostril where there is no black near it.

It doesn't look like anything to be concerned about. If it's a bruise from banging into something it will heal on its own. Don't put anything on it or you can cause a problem. It's good you are observant of things going on with her
