15 Biggest Unresolved Plot Holes In Harry Potter
7. The Owl Postal Service
In addition to the appetising food, breakfast at Hogwarts also involves the morning post. Owls zoom into the Great Hall and deliver newspapers, letters, and packages to their respective owners. As fun as this may seem, the mechanics of the postal service simply don't make sense.
Are owls in the wizarding world just smarter than ordinary owls? How can they understand human language? Transporting letters from home to Hogwarts and back again is somewhat believable, but the owls in the wizarding world go to many other locations as well. Hedwig even manages to find Sirius Black without an address.
The implication, therefore, is that owls in the wizarding world are highly intelligent. Sadly, the source of their intelligence is never explained.
