What is the name of Harry Potter's owl?

"Hedwig's Theme" is an orchestral piece composed by John Williams. It serves as the main theme for the Harry Potter film series, based on the series of popular fantasy novels of the same name by author J. K. Rowling. The theme first appears in the opening credits of The Philosopher's Stone in the "Prologue" track, a shortened version of the full five-minute theme, which is not featured entirely until the closing credits. The track is named after Harry Potter's pet owl, Hedwig.
