Real life duck army helps farmers clean paddies

In this footage, an army of ducks (previously) helps a farmer in Thailand clean out the paddies.

After the rice crop was harvested on a farm in Nakhon Pathom province in Thailand, a flock of around 10,000 ducks was released from a pen – and instinctively streamed towards the flooded fields to devour pests such as snails hiding in the rice stubble. Drone footage, capturing the spectacle that resembles naturally-occurring animal migration, shows the birds zig-zagging across the fields as they headed towards the nutrient-rich rice paddies.
