  Harry, Ron, and Hermione were all in the Owl Tower, as Harry liked to call it, because Hedwig wasn't allowed to leave. It seemed that some owls had run away which caused Hogwarts to decide that they should all stay cooped up in the tower. Half the owls looked ready to murder the other half and Harry was about to take Hedwig away. Not for Hedwig's safety but for the others, the snowy owl was a force to be reckoned with.
