In a remote part of Antarctica, there are emperor penguins wandering around with GPS trackers like fit bits so researchers can learn more about their feeding patterns and protect them from environmental threats. Physiological and behavioural ecologist Dr Birgitte McDonald from San Jose University is part of the five year US-NZ study. She's heading back to the ice and says the GPS technology is giving researchers valuable new insights into the penguins' behaviour and they can tell us a lot about the impact of climate change.
