Black-bellied sandgrouse

The Black-bellied sandgrouse (Pterocles orientalis) belongs to the Pteroclidae family. While primarily an arid-zone bird, its tendency to forage in agricultural landscapes classifies it as a potential pest in cereal-producing regions. These birds are highly terrestrial, allowing them to traverse large areas of arable land in search of food and water.

This species primarily impacts cereal crops, including wheat and barley, as well as sunflowers. Damage is most significant during the early emergence phase when the birds consume newly sown seeds, and during the grain-filling stage when they feed on the developing kernels. Large flocks can cause substantial local crop losses, significantly reducing the yield potential in affected fields.

The biology of the Black-bellied sandgrouse is uniquely adapted to desert and steppe environments. They nest on the ground, and their survival strategy involves long-distance daily commutes between arid nesting grounds and food sources. This mobility allows them to exploit agricultural fields throughout the growing season, particularly when native seed sources are scarce.

The damage profile is characterized by irregular patches of decimated seedlings or thinned crop stands. By feeding on ripening heads, the birds reduce both the quantity and quality of the grain. Furthermore, their presence on the field can disturb soil structure to a minor degree and, in some cases, encourage the growth of weeds in the cleared patches, which competes with the remaining crop.

Effective management requires non-lethal deterrent strategies to minimize damage without disrupting local ecosystems:

• Deploying visual scare devices such as hawk kites or reflective holographic tapes.
• Using acoustic deterrents like propane cannons or recorded distress calls.
• Ensuring seeds are sown at optimal depths to prevent easy access by ground-feeding birds.
• Managing field borders to reduce the attractiveness of the area for roosting.
