Hawky

Hawky is Sokka's pet Messenger Hawk. In "The Runaway", Sokka bought Hawky with the money Toph had won by cheating at a dice-like game and a test-your-strength game. He had hoped of sending messages to Gran Gran and other far-off friends and relatives; the bird simply shook his head at the suggestion of flying to the south pole. Although Sokka referred to him as a lazy bird, we see no evidence of that; he seems to be a fine specimen of his breed and willing to deliver any message attached to him, within reason. Hawky had something of a short-lived rivalry with Momo and the two frequently got into fights. Though a new addition to the group, he seemed quite loyal to Sokka and apparently understood his speech. Toph and Katara used Hawky to send a letter to Toph's parents and that was his last appearance.
