Zenaida

The genus Zenaida, in the context of agricultural damage, encompasses specific bird species of the Columbidae family that can cause significant losses to cereal and vegetable crops. In regions with high population densities, these birds are recognized as pests that negatively impact crop establishment and yield quality.

Taxonomic classification: Order Columbiformes, Family Columbidae. These birds are highly adaptable to human-modified landscapes, frequently utilizing agricultural fields as primary feeding grounds. Their ability to exploit both natural and artificial food sources makes them persistent threats to intensive farming operations.

The primary crops affected include wheat, barley, maize, sunflowers, and various vegetables. Damage is most severe during the sowing period, as the birds forage on seeds in the soil, and during the ripening stages, when they consume developing grain and fruits, leading to direct economic losses for farmers.

The biology and lifecycle of Zenaida species are marked by high fecundity and rapid breeding cycles. When abundant food is available on farmland, these birds can produce multiple broods per season, causing local population spikes. This continuous presence requires diligent monitoring throughout the growing season.

Damage symptoms include patchy field emergence, destroyed seedlings, and damaged mature heads. To mitigate these impacts, integrated pest management strategies should be adopted:

• Deployment of bioacoustic bird deterrent systems.
• Use of seeds treated with repellent-containing coatings.
• Implementation of visual deterrents across large-scale fields.
• Deep placement of seeds during mechanical drilling to prevent easy access by birds.
