The main system used the airport to control the bird population within the airport grounds is the use of birds of prey.
Within the ground or its area of influence, Barcelona-El Prat coexists with natural areas included in the Spaces of Natural Interest Plan (Plan de Espacios de Interés Natural), such as La Ricarda-Ca L'Arena, El Remolar-Filipinas and La Murtra Lagoon, and Areas of Special Protection for Birds, which include, apart from the aforementioned, the coastal spaces of El Prat and Els Reguerons.
Reconciling aircraft landing and takeoff operations with the presence of birds on the Delta obliges the airport to put in place protocols and services that guarantee aircraft safety. The main system used by Barcelona-El Prat airport to control the bird population within the airport grounds is the use of birds of prey. This service has a series of advantages: it does not alter the existing ecosystem within the airport grounds, it does not disturb normal airport operations and, above all, it offers optimum reliability as, in contrast to the other methods, the birds never get used to the presence of their natural predators.
