Pigs at Schipol airport in Amsterdam help to keep the skies safe from geese

Schipol Airport in Amsterdam is using pigs to scare away geese and thus increase security.

Considered the third largest in Europe, the airport is built on reclaimed land – below water level – and is located about six miles away from the Dutch capital.

The land around the airport is filled with water-covered fields and attracts the geese that come there to eat.

This started to cause concerns for the safety of the aircraft and it was therefore decided that after the harvest, 20 pigs would be allowed to eat the remains and thus nothing would be left for the geese.

The airport also employs 15 full-time workers who drive around the runways to scare off birds.

In the past airport employees were even hired to shoot at and kill geese.
