Duck

The genus Anas (dabbling ducks) belongs to the family Anatidae, order Anseriformes. While they are not classified as typical agricultural pests like insects, in specific agronomic contexts, wild duck populations can pose significant challenges to farmers when their feeding habits overlap with cultivated crop areas.

They primarily impact cereal crops such as wheat, barley, and rice, especially in regions with extensive irrigation systems. Ducks are known to forage on both newly sown seeds and young green seedlings, leading to reduced plant density and potential yield loss, which is particularly critical in early spring.

The biology of these birds is centered around aquatic habitats. During the growing season, they perform regular flights between nesting sites and feeding grounds. Their migratory patterns often lead large flocks to settle in agricultural fields, where their presence becomes a persistent issue for land management.

The damage is caused by both direct feeding and physical trampling of the field. By concentrating in specific areas, ducks can cause significant soil compaction, which hinders the root development of the remaining plants and negatively affects the overall uniformity of the crop canopy.

To minimize damage, farmers employ various protective strategies:

• Deployment of acoustic bird scarers and bio-acoustic systems.
• Installation of visual deterrents like predator decoys and reflective materials.
• Strategic water management to prevent flooding in vulnerable fields.
• Utilization of netting or perimeter fencing for high-value crops.
