A flock of drunken starlings caused chaos on a motorway in Austria earlier this week when they fell onto a stretch of the A2 road between Inzersdorf and Vösendorf, causing traffic jams several kilometres long.
Witnesses described the scene as like something out of a horror film. Some people commented on the unusual event, joking that the birds ought to have been tested for "air worthiness".
Ornithologists were initially confused as to what had caused the birds to fall into the road but now believe that they had gorged on fermented berries, which contain naturally occurring alcohol, and got drunk on them.
Rain and foggy conditions further confused them, so that they didn’t know where they were going and lost their bearings over the motorway, crashing into cars and trucks.
