Oriental turtle dove

The Oriental turtle dove (Streptopelia orientalis) is a member of the Columbiformes order and the Columbidae family. Within agricultural environments, it is recognized as a pest due to its habit of forming large flocks that forage heavily on ripening grain crops.

These birds primarily damage cereal and pulse crops. They cause significant economic losses by consuming seeds during the sowing phase and attacking crops during the milky-wax stage of grain maturity. Common targets include wheat, barley, millet, sunflower, and buckwheat fields.

Their biological behavior is defined by a reliance on nearby woodland or shelterbelts for nesting, from which they undertake daily foraging flights into open fields. Their activity patterns are highly synchronized with the availability of ripening grain, allowing them to rapidly exploit food sources across large areas.

The damage caused by Oriental turtle doves involves not only the consumption of grain from the ear but also the physical trampling of young plants. Their destructiveness is particularly high in fields adjacent to forest fringes. Over time, their presence can lead to patchy crop development and a measurable decrease in net yield.

Effective mitigation strategies focus on non-lethal deterrence and site management. Key measures include the deployment of sound-based deterrents like sonic cannons or bioacoustic devices. Furthermore, using visual scarecrows and raptor imitations helps reduce bird landing frequency. Agronomic practices, such as ensuring deep seed placement during planting and accelerating harvest timing, serve as crucial preventative measures to protect yields.
