A Nest Conserve Bird's LIFE   Natural Pest Control-Sparrows eat insects that harm crops—like aphids, caterpillars, grasshoppers, beetles, and rice pests (e.g., planthoppers, leaf folders).During breeding season, each sparrow can eat up to 300 insects per day, effectively reducing pest populations and the need for chemical pesticides.

2. Weed Seed Cleanup-They also consume weed seeds, helping to naturally control weeds without chemicals.
3. Soil Health (Gentle Tilling)-By pecking and scratching at the soil while foraging, sparrows help mix soil, improving water absorption and root growth.
4. Seed Dispersal & Biodiversity-As they move, sparrows unintentionally spread seeds—either stuck to them or from their droppings—helping plants grow in new places and boosting biodiversity.
5. Environmental Monitoring-Sparrows serve as "eco‑health sensors." A healthy sparrow population often signals a farm with fewer pesticides and better habitat. A drop in their numbers can warn farmers of harmful changes .
