In general, sparrows don't like flashy colors, such as yellow. Therefore, farmers can ward off this pest attack by planting sunflowers or chicken dung flowers. These flowers can be planted in rice fields as borders. That way, birds will be reluctant to approach the rice plants.
Just like flashy colors, sparrows also don't like shiny things. Therefore, bird pests can be driven away by using shiny objects, such as plastic or used discs (audio/video CDs).
Usually, farmers embed wood every 5 meters or according to site conditions. Shiny plastic will be attached to the wood which will reflect the incoming sunlight. Unfortunately, this method has a weakness, namely that when the weather is cloudy, in the morning and evening, the plastic cannot reflect sunlight.
