General Notes
Hedwig is a gift to Harry from Hagrid in the first book of the series, purchased in Diagon Alley while shopping for supplies for Harry's first year at Hogwarts. In the series, owls are used by witches and wizards primarily as message and package couriers, which make owls more useful than the other pets allowed students (rats, toads and cats), so Hedwig is used for messages throughout the series.
