Hi I do not recall much of the movie. It was about a teen age boy perhaps a runaway. He ended up on a mountain. He meet an old recluse who taught him how to live in the forest.
I recall one scene when winter came he survived the snowstorm by staying in a tree hole. As in a tree trunk/stump that was almost hollowed out.
I think he also trained a bird in the movie perhaps a falcon?
I recall that I loved this movie as a child and would like to share it with my
Wife and other younger relatives as from what I remember is that it was a good wholesome movie.
Strange that I can not recall the name! Thanks so much!

You're thinking of 1969's "My Side of the Mountain".
