Rock dove

The rock dove (lat. Columba livia) is a member of the Columbiformes order and the Columbidae family. In an agricultural context, it is considered a significant pest that poses a threat to various field crops and stored agricultural products throughout the growing season.

These birds primarily damage cereal and legume crops, including wheat, barley, maize, sunflowers, and peas. The most critical period of damage occurs during sowing and emergence, as pigeons consume seeds from the soil surface and pull out young seedlings, leading to reduced plant density and significant yield losses.

The biology of this species is characterized by high reproductive rates and social behavior. Pigeons are highly adaptable and live in colonies, allowing them to detect and exploit food sources effectively. This group behavior results in concentrated attacks on agricultural fields, often causing patchy destruction of crops that requires replanting.

The damage profile includes both direct consumption and contamination. Beyond eating seeds, their droppings contaminate stored grain, leading to severe sanitary issues. This contamination can facilitate the spread of avian-borne pathogens and reduce the market value of the crop due to poor grain quality and hygiene standards.

Effective protection measures involve integrated pest management strategies. Farmers often utilize visual deterrents, such as scarecrows or reflective tape, and acoustic devices like gas cannons or bioacoustic systems. Additionally, precise agronomic practices, such as increasing sowing depth and applying seed coatings with deterrent properties, are essential for minimizing bird-related economic losses.
