Of the Ents' beginnings, The Silmarillion states that they were due to arrive when Yavanna's thought would 'summon spirits from afar'. Manwë seems to put them in the same category as the Eagles of the West, as also beings not born in bodies, but with a spiritual entry causing them to 'awake'. It seems to be a catchall explanation for everything from Eagles, to Huan, and maybe even to Tom Bombadil, to say that they are bodies inhabited by Auinur, but that really does seem the likely canon rationalization.
