Mourning dove

Systematic position and description: The Mourning dove (Zenaida macroura) belongs to the order Columbiformes and the family Columbidae. It is a medium-sized bird recognized by its slender build, long pointed tail, and soft, muted plumage. It thrives in diverse habitats, including agricultural fields, where it interacts frequently with human cultivation practices.

Crops affected: This species is known to cause significant damage to a wide range of agricultural crops. Its primary food sources include seeds of wheat, corn, millet, sorghum, and barley. Additionally, Mourning doves are known to forage on sunflower seeds and various other oilseed crops, often targeting fields shortly after sowing or during the grain maturation phase.

Biology and development: Mourning doves are prolific breeders, capable of producing multiple broods per season, which sustains high local populations. They are highly adaptable regarding nesting sites, utilizing both arboreal and ground locations. This adaptability, combined with their ability to forage in large flocks, allows them to exploit agricultural resources efficiently and consistently.

Damage patterns and economic impact: The primary economic damage occurs when the birds consume seeds from the soil surface, leading to reduced plant stand density and the necessity for reseeding. During the grain-filling stage, doves perch on stalks, potentially breaking them, and consume grains directly from the head or ear. This feeding behavior results in significant yield loss and provides entry points for pests and pathogens.

Protection measures: Managing the Mourning dove requires an integrated pest management approach to minimize crop loss while considering local wildlife regulations:

• Installing propane cannons or sonic deterrent devices to discourage foraging.
• Utilizing visual deterrents such as reflective tapes or predatory bird decoys.
• Ensuring deep planting and proper soil cover to make seeds less accessible to ground feeders.
• Applying seed treatments or repellents that are specifically formulated to discourage consumption by avian pests.
