Removal of multiple open garbage dumpsites and introduction of covered containers around the airport have played a key role the number of bird strike and near-miss incidents at Kolkata airport in recent times. Open garbage dumps were a problem as they attracted scavengers which posed a threat to flight operations. Between January and April 2025, there were only four confirmed bird strike incidents reported. This is a considerable improvement when compared to 26 incidents the previous year and 18 in 2023.
The measures taken by airport authorities, including a comprehensive bird and wildlife hazard assessment and the deployment of bird-scaring devices that emit sonic and ultrasonic waves to deter birds during aircraft landing and take-off have also paid dividends. Airport officials noted that pigeons, kites, and lapwings spotted near the airport posed serious safety hazards. While most bird strikes result in minor damage, collisions with windshields or bird ingestion into engines can be extremely dangerous.
Garbage collection sites and uncovered meat shops along the runway approach path needed immediate attention. Additional problematic locations mentioned in the report included open dumps near and behind the airport perimeter wall — many of which lacked proper waste disposal infrastructure. According to Rule 91 of the Aircraft Rules, 1937, it is illegal to slaughter animals, dispose garbage or engage in any activities likely to attract birds or animals within a 10-km radius of an airport. Violations are punishable by up to three years in prison, a fine of up to Rs10 lakhs, or both.
