Scarecrow building is a traditional agricultural practice aimed at protecting crops from birds and other pests. A scarecrow is typically made from materials like old clothes, straw, and wooden poles, designed to resemble a human figure. Farmers place these figures in fields to deter birds from eating seeds and fruits. The process of creating a scarecrow involves gathering materials, such as straw for stuffing and old clothes for the outer layer. Once assembled, scarecrows can be customized with various features, like hats or painted faces, to enhance their effectiveness in keeping pests away from the crops.
