This question already has an answer here:
I do not remember much detail about this book my mother once read to me when I was little. What I do remember is that the protagonist was a boy surviving in a forest. He made his home out of a big tree which he hollowed out. There was a long winter. He had a bunch of animal friends, and I think one was a hawk or a falcon. I think he grew up in the woods if I remember correctly. I think he saved the forest from hunters or something.
I'm not sure; it was like 13 years ago that I heard it, but it has been on my mind. Any suggestions would help. I very vaguely remember the book cover; if I were to see it again, I could tell that it was the book.
