Greater Coucal

The Greater Coucal (Centropus sinensis) belongs to the family Cuculidae within the order Cuculiformes. Unlike common cuckoos, it is a non-parasitic bird that builds its own nests and thrives in tropical regions of Asia, specifically in scrublands, mangroves, and edges of agricultural landscapes where it finds ample shelter and food.

In agricultural settings, the Greater Coucal is recognized for its foraging habits that can negatively impact crop production. While it primarily consumes insects and small vertebrates, it frequently turns to agricultural produce, particularly grains, legumes, and fleshy fruits, when natural resources are scarce or during peak harvest seasons.

The biological success of the species is attributed to its high adaptability and secretive nesting behavior in dense vegetation. Its breeding cycle, often aligned with the monsoon season, coincides with periods of crop development, leading to increased activity within cultivated lands as parent birds forage to feed themselves and their young.

The damage caused by these birds typically involves consumption of grains, leading to direct yield loss, as well as trampling of seedlings. By foraging on the ground or in low-lying crop structures, the Greater Coucal can cause significant structural damage to young plants, often leading to patchy fields that require replanting.

To mitigate the impact of the Greater Coucal on farm yields, producers should implement integrated control measures:

• Management of field margins by removing dense brush and tall weeds that provide nesting habitats.
• Deployment of motion-activated scarecrows or reflective deterrents to minimize bird entry.
• Installation of bird netting over high-value horticultural or vegetable crops.
• Utilization of ultrasonic or acoustic deterrent systems to deter avian pests during vulnerable growth stages.
