Hundreds of farm ducks blocked traffic on a road in Cambodia while heading to a rice field to feed on snails. The footage shows drivers stuck in traffic as the animals surround them. Motorist Ahmom Real said: "The birds knew well what to do and where to go. They are smart, but they were too many, so they caused delays". Ahmom added that her family enjoyed seeing the birds and that some of the riders were entertained by the unusual encounter. The footage was filmed in Cambodia on October 31.
