You are 'not so sure'? Well, I can tell you that, as far as Paquita is concerned, there is no doubt in her mind that it was a real BAD idea

Personally, I have learned not to interfere in any way or change my routine at all. It doesn't really work out... I leave it up to them to figure things out and decide what course of action they prefer to follow. In many cases, when you have a bird that is not bonded to a human and the object of this bird's affections shows a marked preference for the human's company, they do get jealous - it's pretty much unavoidable. But parrots are very smart and even if it takes them a while to figure out that, in reality, you cannot possibly be any kind of real threat to their relationship, it does happen. So, if I were you, I would keep on doing what I've been doing with Paquita all along and just give Rajah some time to come to terms with the situation.
