Owls- Hedwig (Harry Potter's owl)

In Harry Potter, owls' role is to hand out the wizards' post. Hedwig is Harry Potter's snowy owl. In the story, Hedwig is a gift to Harry from Hagrid in the first book of the series, purchased in Diagon Alley while shopping for supplies for Harry's first year at Hogwarts. The name Hedwig is a name Harry found in his schoolbook, A History of Magic. Hedwig is used for messages throughout the series. In the fifth book, Harry Potter and the Order of the Phoenix, Hedwig is intercepted by Professor Dolores Umbridge and is hurt. Harry pretends he feels unwell in History of Magic lesson and sets off to find Professor Grubbly-Plank, Hedwig behind his back. Keeping Hedwig at home during the summer holiday continues to be just one more area of conflict between Harry and the Dursleys. Unfortunately, Hedwig dies in Harry Potter and the Deathly Hallows during the chase and that causes a lot of pain on Harry.

J.K Rowling says that Hedwig is the most beautiful owl of all.

Hedwig dies, oh poor owl
