King penguins struggling on a treadmill could help to save the planet.
Scientists from Birmingham University have fitted 50 of the birds with special heart-rate monitors in an experiment designed to measure global warming.
They will record how much energy the birds are using in order to feed themselves. If the data shows they are making longer trips further into the oceans to find fish, it may prove waters are warming up and climate change is taking place.
