A number of weeks back I adopted a yellow-sided GCC, Sunny. He is still in quarantine. He is less bitey now and gets excited when he sees me. He always steps up and is looking good... healthier-looking now he is off seed and loving pellets and chop and takes daily baths. He's a fantastic little fellow. I have a work commitment this month that requires me to be out of the apartment for stretches that are longer than usual. I monitor him through a webcam and my wife is at home. He has toys but (understandably) gets stir crazy. The breeder was unable to sell his previous cage mate and offered him to me very cheaply. I have no more room for quarantine so i decided to re-introduce them out of cage this morning. After a mildly bitey start they are already inseparable. My new addition is a natural GCC, no mutations. My goodness his bite hurts. He is small but almost breaks the skin. Sunny also bites playfully and it is becoming less and less painful. This evening the new guy began acting (as i interpret it as an idiot monkey parent) aggressively towards me. He looked cheesed off, flutters his wings at me and bites. It is possible he is still scared, and i am working to make him feel at home. I know if a parrot has a person they are bonded with they can become jealous if another parrot also begins to form a friendship with the chosen human. My long-winded question is this: Is the converse situation also true? Is the new guy (I may well name him Mako) threatened by Sunny's existing friendship with me, and experiencing jealousy? Could this be a cause of his angry behaviour? Sunny jumps on my hand and the new guy is Sunny's velcro bird so follows suit. I stand calmly and talk softly to them and offer them sunflower seeds. Mako snatches them then immediately spits them out. I have to wear gloves because his bite is too painful to bear. For such a small head it really is a marvel of biological engineering generating such large bite pressure!
