Documentary makers have filmed vampire bats preying on Humboldt penguin chicks.
The team travelled to the outskirts of the Atacama Desert in southern Peru to record how the penguins interacted with other species.
Despite anecdotal evidence of the bats attacking penguins, the behaviour had never been recorded before.
The extraordinary footage features in the BBC One series Penguins: Spy in the huddle.
Humboldt penguins breed in coastal South America where they hunt fish in the cold waters of the current also named after the German naturalist Alexander von Humboldt.
