I doubt it. Neurological problems in birds don't manifest that way - at least, I've never seen, heard or read about any bird showing that behavior as a sign of neurological problems. There are three reasons why birds have neurological 'problems': trauma, a cardiovascular event that deprived the brain of enough oxygen or severe dietary deficiencies. If he had had trauma, you would know about it because you would have seen the external damage to his head. Same thing with the cardiovascular event - if he had had a stroke, an aneurism, a brain hemorrhage, etc, you would have seen him down and showing ample and more severe symptoms than this. And I doubt it's dietary because it takes a lot of feeding wrong to get this.
My guess is that you think he is calling and looking for the jardine but, in reality, he is doing something different.
