I bought a new stainless steel food bowl for Trudy and have been catching her hitting the side of it with her beak, then preening a few seconds, then hitting the bowl again, repeatedly over and over. It has become a sort of obsession so I took the bowl away from her. Now she has this mark on her beak. Does it look like a bruise to you? I imagine it is from the bowl, but I am a worrier and would like your opinions in case it might look like something else to you.
