Hedwig, Harry Potter’s Owl was a Snowy Owl. Hedwig in the J.K. Rowling series was a magical creature, a faithful messenger. (Text can be personalized on this card with a “bubble mail” ~ a Red Bubble email ~ if you so desire)
According to Wikipedia, "*Hedwig* is Harry Potter’s SNOWY OWL, given to him in Harry Potter and the Philosopher’s Stone as an eleventh birthday present by Rubeus Hagrid, who purchases the owl in Diagon Alley. Hedwig is used for delivering messages throughout the series, and also serves as a companion to Harry, especially during the summers he spends living with the Dursleys when he is unable to interact with other wizards. It is implied throughout the books that Hedwig can fully understand Harry, and to some extent vice versa. In the fifth book, Order of the Phoenix, Hedwig is intercepted by Dolores Umbridge and is hurt, but is later healed by Professor Grubbly-Plank. At the start of Deathly Hallows, Hedwig is killed during Harry’s escape from Privet Drive by a stray Killing Curse (in the film version, she is killed while attacking a pursuing Death Eater trying to hurt Harry). According to Rowling, Hedwig’s life represents Harry’s innocence.
Although the character of Hedwig is female, she is played on film by male owls (female snowy owls have dark patches of plumage, while only the males are completely white, as Hedwig is).
The John Williams composition which serves as title music for the entire film series is named “Hedwig’s Theme”
