My patronus would be a bird; a Water Ouzel (/American Dipper). These birds are quite small (like me), and are usually calm, but are a lot stronger than they look, and will attack if they are provoked, in order to protect their flocks. They are even know to eat larger fish (such as salmon), which shows how strong they can be. They also walk along the bottoms of streams and can see underwater, which is a little unusual, but is very useful :)
