Deer is the common name for a family of ruminant animals grouped by the fact that the males grow antlers in adulthood. Male deer are called stags, whereas females are called does. One particular species of deer is the Scottish stag. Deer is the preferred food of the Hebridean Black breed of dragon.

It is a possible corporeal form of the Patronus Charm.[1]


The deer was a reoccurring Patronus within the Potter family: James Potter, his wife Lily, and his son Harry all have deer for Patronuses. James Potter was also an Animagus who could take the form of a stag. Severus Snape, as a sign of his undying affection for Lily, also had a doe for a Patronus, which persisted long after her death.[2]

The doe that led Harry Potter to Godric Gryffindor's Sword

In 1998, he cast this Patronus as a guide to lead Harry Potter to Godric Gryffindor's Sword hidden within a frozen lake of the Forest of Dean.

It could be possible that Ginny Weasley's Patronus could have changed from a horse to a doe, for her love for her husband, Harry Potter, whose Patronus is a stag.

Deer live in the Forbidden Forest — in May of 1996, when Rubeus Hagrid was discussing Grawp with Harry and Hermione, he said that he was able to get his own food; "birds an' deer an' stuff."[3]
