Every Main Character's Patronus Explained

A few other Patronuses make their appearance in the "Harry Potter" films with some backstory from the books. Seamus Finnigan's Patronus is a fox, Cho Chang has a swan, and Ernie MacMillan has a boar. During the Battle of Hogwarts, "Harry Potter and the Deathly Hallows" reads, "then a silver hare, a boar and a fox soared past Harry, Ron and Hermione's heads: the Dementors fell back before the creatures' approach. Three more people had arrived out of the darkness to stand beside them, their wands outstretched, continuing to cast their Patronuses: Luna, Ernie and Seamus."

Professor Dumbledore's brother Aberforth, owner of the Hog's Head Inn, has a goat, much like the goats he cared for, though that Patronus doesn't make it into the films. Also in "Deathly Hallows," Aberforth convinces a gaggle of Death Eaters looking for Harry after seeing his stag Patronus that they had seen his goat Patronus instead.

Kingsley Shacklebolt also has a pretty cool Patronus — a lynx. The slick, big cat is perfect for Kingsley. The powerful Auror drops his lynx Patronus right in the middle of Bill Weasley and Fleur Delacour's wedding.  "Deathly Hallows" reads, "Graceful and gleaming, the lynx landed lightly in the middle of the astonished dancers. Heads turned, as those nearest it froze, absurdly, in mid-dance. Then the Patronus's mouth opened wide and it spoke in the loud, deep, slow voice of Kingsley Shacklebolt. 'The Ministry has fallen. Scrimgeour is dead. They are coming.'"
