Eastern jungle crow

The Eastern jungle crow (Corvus levaillantii) belongs to the order Passeriformes and the family Corvidae. This highly intelligent and adaptable species has successfully integrated into agricultural landscapes, often becoming a significant pest in areas where human farming activities provide abundant food resources.

This bird species is known to cause extensive damage to a wide range of agricultural commodities. Its diet includes field crops such as corn, wheat, and rice, as well as various horticultural products like fruits and vegetables. The vulnerability of these crops is particularly high during the germination phase and the pre-harvest period.

The biology and lifecycle of this crow are characterized by high reproductive success and strong foraging instincts. During the breeding season, parents actively hunt for food to support their chicks, leading to concentrated attacks on nearby crops. Their opportunistic behavior allows them to thrive in diverse environments, making them persistent pests.

The damage caused is primarily mechanical: digging up seeds shortly after sowing, plucking out young seedlings, and pecking at ripening fruits. These activities result in significant economic loss, reduced crop density, and lower quality of agricultural produce, often necessitating additional labor for field management and replanting.

Management and control strategies include the following:

• Implementation of bioacoustic devices that mimic distress calls to frighten the birds.
• Use of physical barriers such as netting to cover high-value crops and seedlings.
• Strategic placement of visual deterrents like motion-activated sprinklers or reflective objects.
• Application of non-toxic taste-based repellents on seeds and plant surfaces to discourage feeding.
