Gwaihir in the Hobbit?

[the real findorfin]

It seems that throughout all the works there are 'spirits' that dont seem to be Maia or valar, such as Ungoliant, Bombadil, dragons spirits, etc. I believe that the eagles, ents and huan, etc are of the same type.

And if this spirit group is not a group by itself, then I would think that they are a very low order of maia, perhaps the least powerful. But or course, that means Bombadil cannot be involved.

I will have to go with 'another order' of spirits.
