What I remember of the film
An old big (tall) wooden? Farmhouse. Located I think in the USA.
The family had European connections.
The boy was bad or evil or misunderstood (not sure)
He could either turn into or see through the eyes of a flying bird. This is something I think that was passed down to him by his grandmother (they discuss it.
There is a scene where a baby or small child is found dead in a wooden bucket I think he is or is believed to be responsible.

I've done imdb searches and I'm flummoxed please help
