Adelie's are a true Antarctic species which are suffering as a result of climate change, The Antarctic Peninsular, their only breeding grounds, is one of the fastest warming areas on the planet. This is causing Adelies to migrate south. They are reducing in numbers, they feed almost exclusively on Krill, which is also declining as a result of climate change.
