The vast water bodies of a paddy field attract avian fauna. These water bodies serve as feeding, breeding, nesting and roosting places for the birds. During the winter, migratory birds arrive the water bodies. Since Mundakan (Rhabi) season coincided with the winter season, there was the highest number of birds in the paddy field. Most of the birds were insectivorous and carnivorous. Insectivorous birds consumed insect pests of paddy and as a result, the number of insect pests in the paddy field was less.
