Corrected entry: Just after Ron says, 'Mails here!', we see the owls dropping various packages to Hogwarts students. The very first owl closeup we see is a brown one and s/he is flying to the right. It's carrying a green package. When the owl drops the package and a student catches it, however, the package has turned blue. (00:53:50)

Correction: They are not meant to be the same package. We are shown two tight close-ups of owls - among many other owls, who are delivering/dropping the mail, which merely serve to illustrate this event. The package the first owl releases is green and rectangle, with string tied around the smaller side, and a student catches a larger, blue, square package with string tied around all of its sides. Two shots later we see another owl drop a tan, rectangle package, with a single string and it cuts to yet another student catching an entirely different smaller package. Neither of these are mistakes.
