Bird Strike Risk in India
Bird strikes are a significant and growing aviation safety concern in India. Annual incidents tracked by the Directorate General of Civil Aviation rose from 775 in 2021 to a record 1,782 in 2025, bringing the five-year total to 6,337 confirmed bird-hit incidents across Indian airports.[^c18][^c34][^c39] The DGCA confirmed in an RTI reply that 1,278 bird strikes were recorded in 2024 alone — roughly three per day — more than double the 528 recorded in 2019.[^c28][^c29][^c33] A separate Rajya Sabha dataset confirmed 1,278 bird strikes and 20 animal strikes in 2024, with 198 aircraft damaged, and zero fatalities from wildlife strikes over the preceding five years.[^c44][^c45] Another Rajya Sabha dataset covering 2020 to June 2025 recorded 5,740 bird strike cases, of which 804 aircraft were damaged.[^c20] 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] Preliminary data for the first half of 2025 showed a sharp decline at several major airports, with Delhi dropping from 130 in all of 2024 to 41 in January–June 2025, suggesting that intensified mitigation measures may be producing measurable results at some locations.[^c43]
India's aviation infrastructure has expanded rapidly — the number of operational airports doubled from 80 in 2015 to 163 by October 2025[^c41] — but regulatory capacity has not kept pace. Nearly half of the DGCA's sanctioned posts (787 out of 1,630) remain vacant, and the Airports Authority of India has 1,279 vacant air traffic controller positions out of 5,537 sanctioned posts.[^c40] These staffing shortfalls complicate enforcement of wildlife hazard management regulations, including the monitoring and closure of Rule 91 violations — garbage dumps, slaughterhouses, and other bird-attracting activities within the 10-kilometre aerodrome restriction zone. Bird strikes have been described as "often the final manifestation of broader failures in civic governance, including poor urban planning, weak municipal enforcement, unmanaged waste, and ecological neglect beyond the aerodrome perimeter."[^c25]
The ecological drivers of bird strike risk are closely tied to waste management and urban governance. [[ecology/black-kite|Black kites]], which account for 62% of damaging strikes, thrive on food scraps from open landfills.[^c13] India lies 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 and managed through open dumps that lie within the 10-kilometre restriction zone. Safety advocacy organisations have argued that wildlife hazard mitigation "cannot succeed through airside action alone."[^c19]
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]]. India reported to the ICAO APAC Wildlife Hazard Management Working Group in May 2025 that the rate of total wildlife strikes per 10,000 movements showed a decreasing trend in 2024 compared to 2023, with new Safety Performance Indicators tracking strikes by height band (0–100 feet at the airport boundary; 101–2,500 feet within 13 km of the Aerodrome Reference Point). The first meeting of the National Wildlife Hazard Management Committee was convened at DGCA headquarters in July 2025 under Director General Faiz Ahmed Kidwai, where a critical gap was identified: bird species were identified in only 24% of strike incidents.[^c46] However, implementation on the ground remains inconsistent: Airfield Environment Management Committees at many airports function mostly on paper, and Rule 91 violations persist across major cities.
In a significant enforcement development, the Jammu and Kashmir government became one of the first Indian states to establish dedicated divisional-level committees in December 2025 to monitor and regulate bird-attracting activities near Srinagar International Airport, with quarterly compliance reports to the DGCA.[^c36] The Divisional Commissioner of Jammu also ordered a ban on open garbage dumping and dead animal carcass disposal near Jammu Airport. Other enforcement actions in 2025–2026 include the Indian Air Force considering police complaints against garbage dumpers near Pune's Lohegaon airbase, the AAI blocking a garbage processing plant near Chandigarh Airport, and waste removal at Kolapakkam near Chennai airport under Rule 91.[^c30][^c31] Mumbai launched a startup innovation challenge to develop technology-driven deterrent solutions for the Versova waste transfer centre.[^c32] Patna's Airport Environment Management Committee, chaired by the Divisional Commissioner, ordered strict enforcement of DGCA norms including a crackdown on open meat and fish shops near the airport and infrastructure upgrades including CAT-I lighting and DVOR navigation systems.
Success stories in mitigation
Several Indian airports have demonstrated that coordinated action can significantly reduce bird strike rates. Ahmedabad's Sardar Vallabhbhai Patel International Airport reduced bird strikes from 53 in the first 10 months of 2023 to 32 in the first 10 months of 2024 — a 40% decline — through a comprehensive programme including targeted vegetation management using plant growth regulators (a first-of-its-kind approach in India), advanced light traps for insect control, customised anti-perching devices, bioacoustic deterrents, and one of India's first wildlife relocation programmes.[^c35] [[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 and introduction of covered waste containers.[^c10] Thiruvananthapuram International Airport deployed 24/7 special squads that reduced bird strikes from above 11 to under 4 per 10,000 movements.[^c11] Delhi IGI Airport recorded 41 bird strikes in the first half of 2025, down from 130 in all of 2024, with the decline attributed to sustained implementation of Wildlife Hazard Management Plan measures.[^c43]
Historical context: BNHS and species identification
The Bombay Natural History Society has been identifying bird remains from aircraft strikes since 1966 for both civil and military aviation.[^c6] The BNHS Bird Hazard Research Cell, funded by the Ministry of Defence since 1980, analysed 460 strike incidents between 1966 and 1991, 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 also prepared India's national bird-strike reporting form based on the ICAO standard. More recently, BNHS conducted extensive studies for the Navi Mumbai International Airport, documenting 266 bird species in a baseline survey and later finding that local bird movements are restricted to altitudes below 50 metres — well below aircraft flight paths.[^c37]
Off-airport hazards
Despite Rule 91's prohibition on garbage dumping within 10 km of aerodromes, violations remain widespread. In March 2025, untreated waste from Delhi's IGI Airport was found to be illegally dumped at Rangpuri Pahari, a site that "falls under the line of sight of aircraft landing."[^c21] The [[organizations/international-collaborations|Wildlife Institute of India]] assessed the proposed Puri airport near Chilika Lake and recommended rejection, warning that 95% of bird strikes occur below 2,000 feet — the exact altitude aircraft would occupy near the site.[^c26][^c27] 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]
Institutional and technological developments
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.[^c46] Bird strikes are investigated by the [[organizations/dgca-and-aaib-roles|Aircraft Accident Investigation Bureau]] with safety recommendations forwarded to the DGCA for enforcement.[^c16]
India has developed several indigenous technologies for bird strike mitigation. OIS Advanced Technology launched the industry's first true 3D avian radar system with an 11 km detection range and 360-degree coverage, though no Indian civil airport or IAF base has confirmed deployment as of 2026 after four failed IAF procurement attempts between 2010 and 2021.[^c23] Researchers from Amrita Vishwa Vidyapeetham developed a YOLOv8-based AI system using standard webcam technology for real-time bird detection and distance estimation, offering a low-cost alternative to radar. The E-Raptor, a biomimetic falcon-inspired drone developed by AXISCADES Aerospace and France's Electronic Bird Control, was introduced to the Indian market in November 2025 for bird control operations at airports.[^c38] A Bangalore-based team developed AEROSHIELD, a predictive AI wildlife strike prevention network that uses multi-sensor detection (radar, thermal, acoustic) to forecast wildlife movement trajectories and autonomously activate deterrent drones and acoustic systems before incursions occur.[^c42] The Centre for Cellular and Molecular Biology has commercialized a DNA-based method for species identification in bird hit cases, listed as "Already Commercialised" on the CSIR technology portal.[^c24] National Aerospace Laboratories operates one of the world's largest bird strike airguns for component testing.[^c15]
