Author's Note: Hedwig's death was a big blow for me, though other people insist that she was "just an owl."
In Memory of a Snowy Owl
Lavender
She had seen her several times at breakfast in school, standing out brilliantly against the other owls. The owl's snow-white feathers were more beautiful than any other color, she had always thought, and Parvati had agreed wholeheartedly. For many years after she left school, she had no idea that her favorite owl was no longer. She only learned of her death when she'd bumped into Harry with his wife and children at King's Cross Station, and it somehow entered the conversation. Though she had never even known the creature, she felt a pang of sorrow when she heard that the owl of such pure appearance was dead.
Ron
He had never admitted it to his best friend, but he had always been somewhat jealous of Harry's pet. The beautiful snowy owl was so special, so beautiful, and all he had was a rat, he'd always thought, and he couldn't help feeling slightly annoyed at Hedwig for existing. When the rat turned out to be a man, the very man who'd betrayed Harry's parents, and he finally received an owl of his own, he was disappointed that it was so ugly and useless-looking compared to the grand Hedwig. But when Harry's owl died, he was much sadder than he thought he'd be, and regretted ever harboring any negative feelings toward her.

In her fifth year, Harry was already in the Owlery when she stepped in to send her mother the birthday presents she'd purchased. As she selected one of the school's owls, she felt embarrassed that she was using them, as she knew Harry had an owl of his own, a gorgeous snowy. Harry's owl was one she'd always liked, and when she heard from her friend Padma, a Ravenclaw girl who was a year younger than her (who'd heard from Parvati, her twin, who'd heard from her friend Lavender), that Hedwig had died, she felt a strange feeling inside her that she couldn't identify, a feeling of loss that she couldn't quite place her finger on.
Hagrid
She had been the best present he'd ever given anyone. When he saw her in the owl shop, he had fallen in love with her immediately. He'd asked Harry if she was a good one to buy, and Harry had agreed to it. He was pleased that Harry liked her, because he didn't think he would've wanted to buy any other owl once he'd met the snowy one. He knew that she had been Harry's one companion who stayed with him even when the others couldn't. When she died, he told Harry that she had led a good, long life, but he wasn't fooling himself. It had been all he could do to keep from crying.
Harry
He should've taken a picture of her. Why had he never done that? Now all he had left were memories. He should've known that would happen. Owls didn't live forever. But Hedwig . . . she had seemed so strong, so invincible. That didn't prevent her from dropping dead in her cage when the Killing Curse hit her, though. His one comfort was that he would never forget her, that except for the most recent one, all the memories he had of her were happy ones. He would always remember her as the sweet, strong, happy, beautiful owl that she was.
lost to the world but forever in our hearts
