Penguin dives with onboard camera
The feeding habits of penguins have been captured on camera by the birds themselves.
Japanese scientists fitted head- and back-mounted cameras to Adelie penguins in the Antarctic to record natural behaviour below the waves.
In addition to seeing how the birds feed, researchers recorded short, non-foraging dives.
In this clip, a penguin makes a series of short dives and films its fellow birds underwater. You then see footage of a penguin hunting krill and then a penguin captures a fish under ice.
The footage of the fast moving birds was slowed down to a quarter of its real speed so scientists could analyse penguin foraging behaviour.
