”The loss of Hedwig represented a loss of innocence and security. She has been almost like a cuddly toy to Harry at times. Voldemort killing her marked the end of [Harry’s] childhood. I’m sorry… I know that death upset a LOT of people!
Hedwig was a gift to Harry on his eleventh birthday from Rubeus Hagrid and was purchased from Eeylops Owl Emporium. Owls are used by wizards to deliver mail, but Hedwig was also an important companion as Harry was initiated into the wizarding world.
