The Birder's Guide to Everything (2013)

This is an entirely enjoyable indy movie about a 15 year old boy, David (played so naturally by Kodi Smit-McPhee) who has lost his mother 18 months before.  He is struggling mightily with his grief and add onto that the anger he has at his father, who is getting remarried, and to one of the nurses who took care of his mother over the course of her illness.

David's mother was an exceptional birder, and she passed the love of the hobby onto her son, who recognizes birds by their GISS (which is pronounced JIZZ,for reasons which escape me because it seems like potty humor and many birders are well above the age where that would be appropriate)--the general impression of their size and shape--as well as by their songs.  He is humble and shy and intense all at the same time.

The movie is about how he uses birding and his peers to find a way to forgive his father, to let go of his anger and see what his father is going through.  It is a sweet story that is told in a soft way.  Very enjoyable.
