Authorities in New Zealand recently found out the reason for their road cones being oddly placed.
Despite leaving them in specific places they were dumbfounded to find the cones always seemed to have moved by the time they returned.

It wasn't a group of mischievous teenagers or some prankster children though, as you might expect.
Kea parrots were found to be the surprise culprits.
The NZ Transport Agency trawled through camera footage after they were left puzzled by the moving road cones.
The agency has advised people not to feed the endangered kea near the traffic.
They have since said that they will trial heavier road cones to discourage the birds' cheeky behaviour.
