Laughing dove

The Laughing dove (Streptopelia senegalensis) is a member of the Columbidae family, classified under the order Columbiformes. In agricultural landscapes, particularly within warm climate zones, this species is frequently identified as a nuisance and a pest due to its habit of feeding on freshly sown crops and ripening grains, leading to measurable yield losses.

The primary crops affected by the laughing dove include wheat, millet, sorghum, and various oilseeds like sunflowers. The species is highly adapted to human-altered environments, frequently exploiting agricultural fields as a primary food source, which leads to dense concentrations of birds in areas undergoing agricultural development.

Regarding its biology, the laughing dove exhibits a high reproductive rate, often breeding year-round if resources are abundant. This rapid proliferation allows populations to remain stable and high, creating a constant pressure on surrounding arable land. Nesting in proximity to agricultural sites reduces the energy expenditure for foraging, leading to intensified damage.

The damage profile is twofold. First, they consume seeds directly from the soil immediately after sowing, causing poor germination and uneven crop stands. Second, during the ripening stage, they feed on mature grain directly from the ear or head. This feeding behavior often causes significant scattering and loss of grain, coupled with the crushing of stems by the weight of large flocks.

Management and protection strategies require an integrated approach. Effective methods include:

• Deploying sonic and ultrasonic bird deterrents at critical crop growth stages.
• Utilizing visual deterrents such as reflective tapes or silhouette decoys of predators.
• Maintaining proper seed depth to prevent easy access to sown materials.
• Implementing habitat modification by reducing weed cover near field margins.
