Forget Happy Feet - these criminal penguins have Sticky Hands ... er, make that Sticky Beaks:
A "criminal" stone-stealing Adelie penguin has been captured on camera by a BBC film crew.
The team, filming for the documentary Frozen Planet, spent four months with the penguin colony on Ross Island, Antarctica.
The footage they captured shows a male penguin stealing stones from its neighbour's nest.
The birds build their stone nests to elevate and protect their eggs from run-off when the Antarctic ice melts.
Males with the best nests are more likely to attract a mate, so, in a colony of half a million penguins, the best stones are highly prized.
