Wind vanes can be made with many different animals. This weather vane is made with a rooster. Below the rooster is an arrow. The arrow is moved by the wind. When the wind blows it moves the arrow and points to the direction the wind is coming from. In the picture the wind has moved the arrow to point to the letter, S.. This means that the wind is blowing south. Each letter on the weather vane is the start of a different word.
