Millions of birds vacuumed to death annually in Mediterranean

New research has discovered that millions of birds are being vacuumed up as part of nocturnal suction olive harvesting in the Mediterranean. Huge numbers of birds from central and northern Europe winter in the Mediterranean, and while they are roosting at night the olive picking machines begin their work. A separate study found that nearly 100,000 birds die annually in Portugal as a result of suction olive harvesting.
