With the 2012 Olympics fast approaching, penguins at London Zoo have been getting into the spirit of the games.

A new diving board has been installed in the penguin enclosure, so the zoo's 64 birds can perfect their flips in time for the summer.

Head bird keeper Adrian Walls said: "We have installed it at the deepest point of their pool, right above the underwater viewing areas, so we should be able to see them giving Tom Daley a run for his money."

In the video clip below, Adrian explains why diving is a 'natural' activity for penguins.
