At Orly airport, Colyne Plessis ensures that no bird disturbs the take-off of planes with its fireworks, sounds and ornithological knowledge. The profession of bird scarer, little known, is essential in airports for the safety of aircraft.
"The animal collision is the second major accident risk for an aircraft," Sylvain Lejal, Orly's biodiversity referent, told AFP. At Orly, the number of incidents requiring take-offs to stop or return to the airport has even halved since 2014.
