I have just recently gotten An African Grey Congo, Igor. This bird is 1 1/2 years old, a real sweetheart, I got her from a breeder, knowing that she was a nervous one, with a tendency to pluck a little off her chest, she did pluck a little the first few days home, but my husband and I did everything we could to help her feel as loved and secure as we could, and she seems to have stopped and to be adjusting quite fine. I have been trying to read as much as I can on parrot training, and "people" training, lol. But I haven't come across beak banging in any of my books, Should I be concerned? The first time my Igor did this she was playing ontop of her cage, I heard this banging, and looked to see it was Igor, so I put her on her playgym, and it stopped, this morning I noticed the same, but I gave it a few mins, and Igor stopped and then moved to play with something, Is this just playing? boredom or something I should be concerned with, I wouldn't want my sweetie to hurt herself, but I also do not want to interrupt something that is natural for her to be doing.
