Father and son duo build recycling machine operated by magpies
A father and son have created a fully-functional rubbish recycling machine that is completely run by magpies.
Tomas Morsing, 57, and Olof, 20, from Sweden use a 'task and reward' system to harness the Corvid's intelligence to clear rubbish in their neighbourhood.
Video shows the basic principle involves magpies picking up litter and placing it in a compartment where it is sorted.
Seeds are then released as a reward for the hungry birds.
The duo has recorded 5,000 magpies approaching the contraption to give up their offerings - between five and 30-a-day - during the past 10 months.
