The openness, vastness and tranquillity of the airports coupled with the availability of food, nesting, roosting and breeding habitats attract birds especially raptors to newly created habitats like the aerodromes (Satheesan, 1996). An ecological study of bird hazard at 30 Indian aerodromes was conducted between 1980 and 1993 (Grubh, 1989). Based on the analysis from 522 remains of the aircraft strikes between 1966 and 1993, it was concluded that 55.4% of the incidents involved 18 species of raptors. Vultures (Gyps and Neophron spp.) and kites (Milers spp.) the commonest of the raptors on the Indian subcontinent were involved in 48.4% of them.

Since the above aspect does not form the part of the scope of work agreed upon for the present study, no observations were made in this respect. Based on the results of studies conducted elsewhere, the possibility of incidences of bird strikes in the proposed airport cannot be completely ruled out. The data provided by the Indian Air force and Indian Airlines from various airports in the North Eastern region however suggests that the incidence of bird hit is quite low.
