Owl from Winnie the Pooh vs Hedwig from Harry Potter

Vote here for Hedwig

Hedwig (d. 27 July 1997) was Harry Potter's pet female snowy owl. Hedwig was an eleventh birthday gift from Rubeus Hagrid to Harry. Hagrid purchased her at the Eeylops Owl Emporium.

In addition to delivering mail, the typical use owls are put to, Hedwig was also a close companion to Harry. She remained one of his closest friends right up to her death during the Battle of the Seven Potters at the height of the Second Wizarding War.
