What does exactly "wave" mean in the above sentence? I would be grateful if you make a reference to one of the Oxford, Longman, Webster, or Cambridge dictionaries as well with regard to its sense. Here is the context:
The owl then fluttered onto the floor and began to attack Hagrid's coat. "Don't do that". Harry tried to wave the owl out of the way, but it snapped its beak fiercely at him and carried on savaging the coat.
