The top picture is of a decorative scarecrow used at this time of year. The stick can be stuck in to a bale of hay or the ground. These scarecrows brighten up a Halloween display and if you don’t want to buy one, you can make one.
The bottom picture us if a scarecrow on the job in a field. These scarecrows keep away crows that would eat the crops. They do work as far as I have been told.
When you see a field with a scarecrow, you won’t see crows.
