Millions of birds are being vacuumed up and killed during nocturnal suction olive harvesting in Spain and Portugal.
In Spain, 2.6 million birds die every year from being vacuumed, and in Portugal, 96,000 birds die per year.
Birds from northern Europe winter in these countries, and are at risk while roosting at night, according to BirdGuides.
The noise and light of the machines dazzle the birds, which are then sucked into suction olive harvesting machines and killed.
