Turtle doves

The genus Streptopelia, commonly referred to as turtle doves, belongs to the order Columbiformes and the family Columbidae. In an agricultural context, these birds are recognized as significant pests that can inflict substantial damage on various field crops, particularly during the critical stages of sowing and germination.

These birds primarily target cereals like wheat, barley, and millet, as well as sunflowers and corn. They are notorious for foraging on freshly sown seeds, digging them up from shallow soil depths, and attacking emerging seedlings. This behavior often leads to significant crop thinning and necessitates expensive reseeding operations.

The biology of Streptopelia is characterized by high reproductive success and adaptability to human-altered environments. With multiple broods per breeding season, their population density can escalate rapidly in agricultural regions, ensuring that there is a constant pressure of avian foraging activity throughout the planting window.

The economic impact of turtle doves is reflected in both direct yield loss and increased production costs. Beyond consuming the seeds, their presence in large flocks leads to soil compaction around the feeding areas and potential sanitary issues, as they may act as vectors for agricultural pathogens and weed seeds via their droppings.

Effective management strategies require an integrated approach to mitigate bird pressure:

• Ensure precise seed placement with optimal planting depth to make seeds less accessible.
• Deploy bioacoustic repelling systems that mimic predator calls.
• Use visual deterrents such as reflective tape, scarecrows, and predatory kite silhouettes.
• Implement crop rotation and field sanitation to reduce attractiveness of the area to flocks.
