A scarecrow is a special type of decoy in the shape of a human placed in fields to keep birds from disturbing and feeding on seed and crops. Modern scarecrows, though remaining decoys, sometimes take other shapes. Reflective aluminum ribbons are tied to plants to shimmer in the sun. In Japan, kakashi is the modern Japanese word for a scarecrow, though there are references in Shinto mythology of the Kuebiko god of agriculture, represented as a scarecrow. These days scarecrow events and festivals are popular around the world in Autumn. They are held in Scotland, Canada, Japan, the USA and the United Kingdom.
