Park rangers monitoring the placement of rat poison on North Seymour Island in the Galapagos Archipelago.
Ecuador used drones to scatter rat poison on one of the Galapagos Islands in a bid to protect species including the world's only nocturnal seagull from the pests, the archipelago's national parks authority, PNG, shared.
The experiment, in which 3,000kg of poison was distributed, was the first using drones, although some poison was also spread by rangers.
