Hawky

Hawky is Sokka's pet Messenger Hawk. He bought Hawky in Fire Fountain City with the money Toph had won by some of her scams. He had hoped to send messages to Gran Gran, as well as other far-off friends and relatives. Instead, 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, willing to deliver any message attached to him, within reason. Hawky had something of a short-lived rivalry with Momo, as 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. It is unknown if Sokka ever saw Hawky again.
