Bird strikes rise, CCMB offers DNA based airport solution
HYDERABAD:Â Even a small bird strike during take off can put pilots on alert, regardless of aircraft size. Bird feathers or body parts can get lodged in sensitive equipment, leading to engine failure and potential accidents.
As a result, emergency landings are often required after bird strikes. To prevent this, airport authorities use loudspeakers, fireworks and laser technology to scare birds away. Ahmedabad airport alone spends ₹15–20 lakh every month on fireworks. Despite these measures, results remain temporary.
Bird strike incidents double nationwide
According to data released by the Directorate General of Civil Aviation, birds struck aircraft 1,278 times across India in 2024, compared with 528 incidents in 2019. The number has more than doubled in five years.
Hyderabad recorded 207 bird strike incidents between 2020 and the first half of 2025. The year-wise figures are: 33 in 2020, 29 in 2021, 38 in 2022, 48 in 2023, 43 in 2024, and 16 in the first six months of 2025.
Ahmedabad reported 373 bird strikes over the past five years, the highest among Indian cities.
CCMB’s DNA technology shows promise
The Centre for Cellular and Molecular Biology (CCMB), Hyderabad, has developed a solution using universal primer technology based on DNA barcoding.
Through DNA analysis of bird droppings, feathers and blood samples collected near airports, scientists identified remnants of rodents, grasshoppers and grass seeds. Based on these findings, authorities are focusing on rodent control and removal of specific grass species to reduce bird movement.
The method is currently being implemented at Rajiv Gandhi International Airport, Hyderabad.
Scientists led by Ajay Gaur at CCMB recently trained officials of the upcoming Noida International Airport in Hyderabad on how to collect bird waste samples for testing. Experts said if the method proves effective, it could significantly reduce the risk of bird strikes to aircraft.
