Bird Strike Risk in India
Bird strikes are a significant and growing aviation safety concern in India. Annual incidents rose from 378 in 2010 to a record 1,782 in 2025, with government data showing 309 (2020), 354 (2021), 588 (2022), a peak of 709 (2023), 609 (2024), and 238 in the first half of 2025.[^c1][^c12] Delhi's Indira Gandhi International Airport recorded 695 bird hits since 2020, the highest of any Indian airport, followed by Mumbai (407), Bengaluru (343), and Ahmedabad (337).[^c2][^c3] For detailed statistics, see [[incidents/bird-strike-statistics-and-trends]]; for the regulatory framework, see [[regulations/dgca-bird-strike-directives]]; for airport-level programs, see [[airports/major-airport-programs]].
The ecological drivers of bird strike risk are closely tied to waste management. [[ecology/black-kite|Black kites]], which account for 62% of damaging strikes and have the highest probability of causing damage (61.17%) when struck, thrive on food scraps from open landfills.[^c13] India sits along the [[ecology/central-asian-flyway|Central Asian Flyway]], a major migratory route, and generates over 1,60,000 tonnes of municipal solid waste daily — much of it unprocessed — creating persistent feeding grounds near airports. Research on long-term population changes at Indian airfields found that Agra recorded a 10.3-fold increase in Black Kite activity over forty years, directly linked to the absence of scientific waste management, while Sirsa and Jodhpur — which adopted solid waste processing plants in 2006 — kept kite populations under control.[^c8][^c9] Overall, 55% of bird strike incidents in Indian civil and air force airfields have been attributed to black kites, bats, and lapwings.[^c5]
The regulatory framework is centred on the Directorate General of Civil Aviation, which mandates Wildlife Hazard Management Plans at all licensed airports, prohibits bird-attracting activities within 10 kilometres of aerodromes under [[regulations/rule-91-10-kilometre-restriction-zone|Rule 91 of the Aircraft Rules 1937]], and requires monthly reporting of strike data. The Bharatiya Vayuyan Adhiniyam 2024 enhanced penalties, raising the maximum fine to ₹1 crore. Wildlife strikes have been designated as a National High-Risk Category under India's [[regulations/national-aviation-safety-plan-2024-2028|National Aviation Safety Plan 2024–2028]]. The bird strike rate per 10,000 flights rose from 4.26 in September 2022 to 9.68 in September 2024, closely tracking the NASP 2024 target of 9.86.
A 2025 study across seven Indian civil airfields recorded 137 bird species and developed the [[methodology/bird-hazard-value|Bird Hazard Value (BHV)]] methodology for ranking species by risk.[^c14] The highest-risk species were the rock pigeon (BHV 144.47), black kite (98.23), house crow (85.55), common myna (54.05), and red-wattled lapwing (32.47).[^c4] Despite this, bird species were identified in only 24% of strike incidents — a gap the DGCA has addressed through a revised reporting form mandating detailed species identification. The Indian Air Force's Ornithology Cell, established in 2010, has achieved over 80% species identification through DNA barcoding, accounting for 1 million birds across 18 airfields.
Historical context: BNHS and species identification
The [[organizations/bombay-natural-history-society|Bombay Natural History Society]] has been central to bird strike prevention in India since 1966, when it began identifying bird remains from aircraft strikes for civil and military aviation.[^c6] Between 1966 and 1991, the BNHS analysed 460 strike incidents, finding that soaring birds (vultures, kites, harriers) caused 52.83% of strikes, with the Black Kite alone responsible for 25% and the Whitebacked Vulture for 11%.[^c7] By 1991, 73 bird species had been identified from strike remains. The BNHS Bird Hazard Research Cell, funded by the Ministry of Defence since 1980, also prepared India's national bird-strike reporting form based on the ICAO standard.
Waste management success stories
Waste management interventions have produced substantial reductions in bird strikes at several airports. [[technologies/waste-management|Kolkata's Netaji Subhas Chandra Bose International Airport]] reduced confirmed bird strikes from 26 (2024) to 4 (January–April 2025) — an 85% decline — through coordinated removal of open garbage dumps, introduction of covered waste containers, and sonic deterrents deployed through the Aerodrome Environment Management Committee.[^c10] [[airports/major-airport-programs|Thiruvananthapuram International Airport]] deployed 24/7 special squads of health inspectors across 10 wards within 4 kilometres of the airport, capturing video evidence of violations and lodging FIRs under the Aircraft Rules. The bird strike rate fell from above 11 to under 4 per 10,000 aircraft movements.[^c11] Ahmedabad airport shut down 18 bird-feeding sites and translocated nearly 1,000 giant fruit bats alongside multiple bird species after the AI-171 crash. In Bhubaneswar, the municipal corporation mandated strict waste management for non-vegetarian vendors in January 2026, requiring biodegradable bags and leak-proof bins under penalty of trade licence suspension.[^c17]
Detection, deterrents, and testing
Indian airports employ a range of technologies — including pyrotechnics, bioacoustic systems, ultrasonic deterrents, anti-perching devices, and plant growth regulators for vegetation management — with varying effectiveness. The [[organizations/research-and-training-institutes|National Aerospace Laboratories]] in Bangalore operates one of the world's largest bird strike airguns, capable of testing aircraft components to international certification standards.[^c15] The [[organizations/research-and-training-institutes|Centre for Cellular and Molecular Biology]] has deployed DNA barcoding at Hyderabad and Noida airports to identify bird-attracting food sources, enabling targeted habitat management.
Institutional framework
Bird strikes are investigated by the [[organizations/dgca-and-aaib-roles|Aircraft Accident Investigation Bureau]] under the Aircraft (Investigation of Accidents and Incidents) Rules, with safety recommendations forwarded to the DGCA for enforcement.[^c16] This investigative pipeline — AAIB evidence collection, BNHS species identification, safety recommendations, DGCA enforcement — forms the institutional backbone of bird strike investigation in India. The National Wildlife Hazard Management Committee, chaired by the DGCA Director General, convened for the first time in 2025 to coordinate nationwide efforts.
