The bird of happinnes (story)

I was listening a short story on audio-book and I want to tell you about it.

A long time ago in the north of Russia, there was a family with a little boy called Igor. His father worked as a woodcutter and his mother worked as a clothes designer. They were a very poor family.
One day in winter, Igor became serious ill and the doctor could not do anything. Igor loved birdsong and he wanted to have a bird above his bed to listen to. Because it was winter there weren't  any birds in the forest, so the father decided to make a wooden bird. Upon completion he hang it up above Igor's bed. When Igor saw the bird he was very happy.
He was trying to touch it with his hand but he could not get it. Every night his father made the string a little shorter until that the boy had to stand up to get it. Since then Igor felt better and since that momenthis father called the bird, "the bird of happiness".
