If any bird control people could reposed. (I assume they are allowed to contribute to this forum, even under the proposed 'show me your ATPL’ rules...)
Bird Control is (in the EU) primarily within airport boundaries. Airports may have local agreements to operate outside boundaries, and will also plot hazard areas, and liase with local planners and environment agencies to try to minimise habitat impact on operations whilst maintaining a sensible ecological balance. For example netting waste disposal sites, lagoons and making areas immediately adjacent to the airfield less attractive to birds. Schipol is unfortunately in an area frequented by birds as the whole area is a natural habitat, and we are just getting to the start of many species migratory season.
I've been fortunate enough to spend time a few years ago with the AMS bird control unit and they are a highly professional, motivated and innovative unit.
