AHMEDABAD: Researchers from Salim Ali Centre for Ornithology and Natural History have identified 76 species of birds in the 10km radius of the Ahmedabad airport. The bird sightings were recorded from 16,235 encounters. Of the 76 species, 22 were found across all areas of the airport. The researchers found 40 bird species within the airport campus; the figure was 45 in the 2km area from the airport.
The researchers’ recent study is titled ‘Bird hazard in select Indian airfields — Sardar Vallabhbhai Patel International Airport’. Its authors are P Pramod and P V Karunakaran with Anees Khan and Binisha B. Their centre is based in Coimbatore. The report was submitted to the authorities in August 2020.
The researchers had divided the study area in Ahmedabad into various zones: zero km, that is the airport itself; 0-2km; 2-5km; and 5-10km. “High congregation of blue rock pigeon was observed inside the airport area,” the study said. “The building owned and managed by the airport authority is being used as perches and resting sites by these birds.” Pigeon-proofing arrangements are required urgently to control roosting, the study said. It added: “All the unused hangers and buildings in the airport serve as a safe roosting area for these pigeons.” The study suggested that along with pigeon-proofing of buildings, trapping and relocation of the birds be undertaken. It has been suggested that the birds be rehabilitated at least 10km away from the airport.
“There are many solid waste dumping sites and meat or butcher shops located adjacent to one of the landing and take-off quarters of the area,” the study said. “As a result, crows and kites were observed abundantly and frequently in this area.”
Hence the cleanliness of the surrounding landscape is vital to manage these birds and the potential threat from them to aircraft, the study said. “Cleanliness drive and regular surveillance should be conducted specifically in these areas around the airport,” the study said.
The study also suggested that the banks of water bodies be covered with nets to prevent the congregation of water birds.
A focused study on the identified problems about birds has been recommended. The study should cover the birds’ activity pattern and their behavioural aspects such as feeding, roosting, and nesting.
