Lol!! Sounds Macho... When I was in high school, my bestfriend had an Umbrella Cockatoo named Macho.
I love birds, and most birds loved me. I grew up with all sorts of animals, my mom and dad bred birds when I was young, so we had a couple hundred...
But Macho was the stuff of pure evil. He would creep closer to me along the back of the couch if we were on the couch, he would flair up his crest and run chase me around the house going "I'm Macho, I'm Macho, I'm Macho" so loudly. That A-hole bird. lol Yes I KNOW WHO YOU ARE MACHO. Thats all he said... "Hi, I'm Macho."
I have a picture somewhere of when he bit me on the lips... it pierced right through both my lips.
