Cockatoo (Cacatuidae)

Host crops: Cockatoos are highly opportunistic feeders that damage a wide range of crops. They frequently attack cereal crops like wheat, maize, sorghum, and sunflower. Additionally, they cause significant harm to nut orchards, vineyards, and various horticultural fruit crops, targeting both the ripening produce and the seeds.

Biology and life cycle: Cockatoos are long-lived, intelligent birds that maintain complex social structures within flocks. Their breeding depends on cavity availability in mature trees. They exhibit high adaptability to human-altered landscapes, allowing them to exploit agricultural resources efficiently throughout the year or during specific growth stages of the crops.

Nature of damage and harmfulness: The damage is twofold: direct consumption of seeds, grains, and fruits, and secondary mechanical damage. Large flocks can trample crops upon landing and cause breakage of branches in orchards. Furthermore, cockatoos are known to destroy plastic irrigation pipes and electrical infrastructure in fields, adding maintenance costs to the crop losses.

Control measures: Management of cockatoo populations requires a multi-faceted approach. This includes the use of visual deterrents (balloons, raptor kites) and auditory scare devices. High-value crops are often protected using physical netting. Integrated pest management strategies suggest alternating deterrent methods to prevent habituation, combined with habitat management around field boundaries.
