Ronaldsway Airport says it's killed almost 650 birds and more than 180 rabbits and hares since 2019.
A Freedom of Information request asked for the figures - the airport culls birds and animals that can present a threat to aircraft.
The data shows a drastic reduction in 2021 during Covid, when 58 birds were culled compared to well over 100 in other years.
Herring gulls are most commonly killed, along with pheasants, crows and rooks.
