Really interesting to read your posts. I am feeling a bit desperate because my tiny black capped conure is so aggressive with my husband that I am afraid to have them in the same room. He jumped on him yesterday and bit his face. So I have to leave them (we have 2 birds) in their cages in my office when my husband is home. I really don't know what to do. Jade will puff up and start grumbling the minute he sees my husband now, even across the room. Do you have any suggestions?
I've had the best initial success when Beaker is just distracted enough with my wife that he won't try to hunt me down (otherwise I fear I will reinforce bad behavior). Then I'll clicker a click and give him a treat. At first I had to get creative to give him the treat by either dropping it a short distance out of reach or protecting my hand (hence the glove-in-sock hand protection), but now I can use my bare fingers.
After the clicker sound was associated with treats, the very first thing I started with was "Beaker, touch my hand!" (with glove). Now I can ask him and he gently comes up to my hand and will tongue my fingers a little bit. I've added "touch your wing" to our repertoire, but he's still not used to sharing that space with me. I also have the added benefit of using the clicker method to get him to calm down when he is on his cage. His feathers will flatten and his neck would stretch out so fast that he looks like he belongs in the loony bin.
Now that I've done some more reading about bird behavior, it makes sense that Beaker would want to fight me. I've learned that most birds will only show this kind of aggression after they know the person. I think it's because he feels safe enough with me to express his feelings ("MINE" or "MY SPACE") with his beak. We might have our squabbles, but when it comes down to it, he actually feels safer with me than any stranger (we almost had a horrible toddler - fid encounter, he stepped up so obediently and hastily to my arm you'd think it was the best thing since shelled pecans!), so progress made!
Unfortunately I've been quite sick this weekend and I have no energy to do anything except hold him for a minute so progress might have just stepped back a step or two.
So to get back to your problem, Ambermai, I saw another thread in which an amazon (I think?) was just being foul (fowl?) towards the guy who posted the topic and mainly him. A major theme in all the replies was that he should have a clicker and click it and leave a treat in an accessible spot for the bird on the cage every time he entered the room. After two days of doing this often, the bird was more interested to hear the next click than to take his face off. - If only I could find the original thread!
