Several previously unknown colonies of the emperor penguin have been discovered by scientists on fresh satellite images. This is an important discovery, given that this bird species is threatened with extinction.
Emperor penguins breed on isolated patches of sea ice. If the ice melts before the chicks fledge, most of the offspring will die. Global warming is exacerbating the melting of the ice, and many penguins are forced to migrate to other areas. In particular, a colony near Hallie Bay has moved about 30 kilometers to the east.
