Sky High,
now you mention the real reason for your request I can understand the reason for your request.
Many airports have far more practical ways of dispersing and discouraging birds, not least of which is the deployment of trained birds of prey in precisely the circumstances which you describe.
Given the maritime environment at BHD, it would be impossible to rid the area entirely of birdlife around the airport and it's vital that they are dispersed for obvious safety reasons, but you may like to suggest the above.
