Conservationists working to alleviate a rat problem in a Galapagos Island have turned to drones to help with their efforts.
The drones have been used to drop poison on more than half of the North Seymour Island in an attempt to wipe out the invasive species which is causing a threat to indigenous birds.
According to a report from the BBC, the drones work much faster and more cheaply than helicopters which have been used in similar rat eradication projects elsewhere.
It went on to describe how, Karl Campbell, South American regional director for Island Conservation, said that drones can deliver poison much more precisely than is possible via helicopter.
Each drone was flown for a number of 15-minute journeys, during which time it is believed they dispensed around 20kg of poison.
