Scientists use satellite imagery to discover new colony of emperor penguins in Antarctica. This is the 66th known colony on the Antarctic coast, nearly half of which have been found by satellite, according to the British Antarctic Survey..

The study used images obtained by the Copernicus Sentinel-2 and Maxar WorldView-3 system.. Droppings that stood out against the background of ice and rocks helped identify traces of the movement of penguins..

Emperor penguins need sea ice to breed. These birds are quite difficult to study, as they are often found in hard-to-reach regions where temperatures drop to -60 degrees Celsius.. Over the past 15 years, scientists from the British Antarctic Survey have been discovering new colonies using litter marks visible on satellite images..

" New satellite imagery of Antarctica's coastline reveals many new colonies.

And while this is good news, like many of the newly discovered locations, this colony is small and located in a region that has been hit hard by the recent disappearance of sea ice,” said study lead author Peter Fretwell..

Emperor penguins are suffering from the loss of sea ice they need during their breeding season. With current climate change projections, this habitat is likely to shrink. According to the latest models, with current warming trends, 80% of the colonies will actually become extinct by the end of the century..

Previously, scientists said that the deer of Svalbard were able to adapt to climate change. They eat grass 'like a popsicle'.
