According to the films, Hedwig's killer might have been Selwyn, who was known to be pursuing Harry and Hagrid at the time since Hedwig's death in the film happened quite a while into the fight when there was only a couple death eaters following them, or it might have been Stanley Shunpike under the Imperius Curse.
It is likely the curse that killed Hedwig was intended for Rubeus Hagrid. He or she most likely took part in the Battle of Hogwarts. It is also likely that, after Lord Voldemort's defeat in 1998, this Death Eater was either killed or imprisoned in Azkaban for their crimes as a Death Eater.
Why did the Death Eater stop chasing Harry after killing Hedwig?
Upon witnessing this, the Death Eaters broke off pursuit, realising this was the real Harry as they considered the Disarming Charm Harry's "trademark" spell, and fell back to inform Voldemort.
In the "Harry's Birthday" special event in Harry Potter: Magic Awakened, Harry reminisces about Hedwig with a Muggle-born Hogwarts student and explains to them that she sacrificed herself to protect him from a Killing Curse.
When he spotted Stan Shunpike, who was only acting under the Imperius Curse, Harry did not want to hurt him, and thus tried to disarm him. The Death Eaters considered this Harry's "trademark" spell, and thus broke off pursuit, knowing he was the real Harry.
Answer and Explanation: No, Hagrid does not die in Harry Potter and the Deathly Hallows. He survives the battle at Hogwarts, and he is later mentioned in Harry Potter and the Cursed Child, which takes place over 18 years after the battle.
According to her, Hedwig's death symbolizes the loss of Harry's innocence as he came of age, so it was very fitting for her to die during the Battle of the Seven Potters in the most obscure book of the series.
At the beginning of the Battle of Hogwarts, the Death Eaters invaded the home of the Acromantula and drove them to attack the school. When the spiders attacked, Hagrid ran forwards to protect them. Acromantula are horribly strong, so it is likely that they captured him and took him to Lord Voldemort.
Known uses. Antonin Dolohov used the curse twice during the Battle of the Department of Mysteries, first against Hermione Granger, who was knocked unconscious but survived.
The curse's effects followed the path of the caster's wand movements, hence if the user slips in their movement, it could either miss or cause an unintended target to be struck, as in the case of the aforementioned incident when Snape accidentally cut off George Weasley's left ear due to a slip in his firing.
Although he wasn't turned into a werewolf, he did develop some wolfish tendencies such as a liking for very rare steaks. He married Fleur on 1 August 1997, although their wedding was disrupted by the arrival of Death Eaters following the fall of the Ministry of Magic.
Mundungus' betrayal caught Moody by surprise and gave Voldemort enough time to cast the Avada Kedavra and kill Mad-Eye Moody. After he was brutally killed by Lord Voldemort, Moody's dead body tragically fell from his broom.
Fred was killed in an explosion possibly caused by Augustus Rookwood. One of the last things Fred heard before dying was Percy joking about resigning from the Ministry. Percy wouldn't leave Fred's side until Harry and Ron helped him move the body to somewhere safer, coincidentally behind a suit of armor.
It's easy to understand why really, as, aside from Hagrid, she was his oldest and most loyal friend in the world. According to J.K. Rowling, Hedwig's death was supposed to signify the end of Harry's childhood.
Similarly, a female owl is called an owl hen and a male owl is called owl coco. A baby owl, in general, is called as an owlet. Owls belong to the family of raptors or preying birds.
Hermione, who intended to purchase an owl, instead buys Crookshanks, over Ron's protests that Scabbers will never get any rest with "that cat" around, and takes him to Hogwarts.
This was because Harry had his mother's eyes. Snape's love for Lily persisted even after she chose James, and it continued after her death. While Snape tried to help Harry when he needed to, seeing the boy reminded him of Lily's loss.
Harry describes Umbridge to Sirius Black, saying that she's vile enough to be a Death Eater, despite not being one. Umbridge is also depicted to be a prejudiced person, despising half-breeds and Muggle-born witches and wizards to the point of firing Hagrid due to his half-giant birth status.
