Corrected entry: When they are meeting in Hogsmeade to discuss having Harry train them in Defense Against The Dark Arts, Susan Bones asks Harry if it was true he could produce a Patronus Charm.

Corrected entry: In Chapter 17 Harry hands an injured Hedwig to Professor Grubbly-Plank who says "Thestrals will sometimes go for birds, of course."

Corrected entry: At the beginning of the book, Harry is given a gift by Sirius. This is a gift that he does not open until after Sirius is dead, and he finds it to be a communication mirror. Not once in the rest of the entire book is this present mentioned. Even when Harry uses the fireplace and risks everything to talk to Sirius, Sirius does not mention opening his present, and during the weeks of Christmas break, when they are actually face to face, no one mentions it either. This is a valid plot hole because it is highly unbelievable that such a valuable gift would have ended up in Harry's hands and not used. With that mirror in use, most of the miscommunication in the book would have been avoided, making the plot seem suspiciously forced.
