"The Emperor penguins which won the hearts of millions of children in the film Happy Feet have suffered a devastating population slump in the last 50 years, according to a report.
Many colonies have fallen in size by 50 per cent as the penguins have been squeezed by the effects of climate change and overfishing, the WWF said
Emperor penguins are one of four species of penguin which breed on the Antarctic ice and are increasingly being driven from their traditional territories.
