Your first movie is
The Enchanted Forest from 1945. I wish I had been clever enough to figure this out myself, but someone from imdb.com actually is the one who dredged up the answer for another poster. A plot summary: "A kindly old hermit who has lived in the California redwood forest for so long that he can commune with the birds and animals saves an infant after a train crash. He raises the child in the forest until the day comes when he reunites the boy with his mother and at the same time saves his beloved sylvan glade. An overlooked family gem from a minor studio."
