Scarecrows are often associated with Halloween and are used for the holiday's decoration. This is most likely because autumn is a time of harvest and scarecrows would be used to detract birds from the ready-to-eat crops. A scarecrow could be used in a book with a Halloween or autumn theme. A book about Halloween and scarecrows should include around what year the scarecrow became a popular Halloween decoration and different types of "Halloween" scarecrows.
Scarecrows are often depicted as happy, silly beings and would make a good main character for a children's book. Like the popular tale of the Wizard of Oz, the scarecrow was used as a lesson for friendship and intelligence. You can use multiple themes such as a children's book about a scarecrow during Halloween night.
People are often interested in the history of such popular icons such as the scarecrow. Scarecrows have been a tool for farmers almost as long as farming has been around. The oldest recorded use of scarecrows were by Egyptian farmers who wanted to protect their stocks of wheat from birds like quail. Unlike the human-esque scarecrow we know today, these were wooden pegs covered in netting.The birds would become entangled and the farmers would take them home to cook.
Today, scarecrows are used for many different purposes: they are decoration during the holidays, gimmicks for businesses, and of course, to detract birds from crops. Create a book on how to make different types of scarecrows for different applications. Traditional scarecrows, animal scarecrows and children-friendly scarecrows are all possibilities. An instructional scarecrow book should include materials needed and practical applications of each type of scarecrow.
