The Brother as bird: Somewhere in between?

In consideration of the other stories that we have read, I believe that it can not be definitively said whether the boy from The Juniper Tree is totally anything on a scale between totally human and totally animal. The brothers from other stories were shown to be transformed as a result of some form of curse while the brother from the Juniper Tree transformed from the bare minimal remains of his body. But would that necessarily be considered a transformation? Or would that be a resurrection? In the other stories, the brothers were alive and then became birds, which I believe signifies a transformation. In the Juniper Tree, the brother is alive, then is killed, goes from inanimate to animate in his resurrection from his own bones to a new bird, and then finally transforms back to the brother after an eye for an eye event. Due to the incorporation of the resurrection stage of the brother's cycle in the Juniper Tree, I believe any definitiveness of his being is lost and his being can not be measured in the totality of anything. Thus I propose that the brother is somewhere in between. The bird is personified when he is able to 1) sing, 2) hold a conversation with the people that he encounters, and 3) comprise a plan of 'vengeance' and act it out. At the very least, I would say that the boy is more bird than human. This is due to the fact that the boy re-enters the world of the living or becomes animate, first as a bird and then is transformed to a human boy later. Some may say that birds can sing, but this birds lyrics consist of personal account, showing that he can not be totally bird. The fact that he remembers and sings about the activities that occurred after his death and before his resurrection, implicates that he is something of higher being and not just totally a bird or totally a human.
