The number of Adelie penguins discovered on the Danger Islands represents more than all the recorded populations in the rest of the Antarctic Peninsula region combined.
Scientists from Oxford University were part of an worldwide team searching for images taken by the Landsat satellites to locate possible large numbers of penguin by identifying the mess they leave behind. Is it linked to the extended sea ice condition over there? "Our results validate the use of Landsat medium-resolution satellite imagery for the detection of new or unknown penguin colonies and highlight the utility of combining satellite imagery with ground and UAV surveys".
When the team got to the islands, they found thousands of penguins nesting at the landing site.
The Danger Islands, said the team, has felt the ravages of climate change less than the western peninsula, and knew very little human activity.
The discovery cements the idea that climate change was behind the decline of penguin populations on the western side of the peninsula, Polito said.
The photos were then stitched together to give a comprehensive picture.

Working off evidence from satellite imagery captured by NASA in 2014, scientists from various institutions mounted an expedition to the area to conduct a population survey - which included the use of drones to help count the number of penguins.
In total, the team logged 751,527 different pairs of penguins living on the islands.
"In the past we've looked at this on the West Antarctic Peninsula versus places like Elephant Island (further to the north)".
It would ban all fishing in a vast area of the Weddell Sea and around the Antarctic Peninsula, safeguarding whales, penguins seals and other species that rely on the krill targeted by fishing ships. The researchers also used a software to do the counting.
"Whether they'll be in or out, we don't know but at least now the people making those decisions will understand how important this area is", she told BBC News.
Researchers think climate change and the melting of thick layers of ice have negatively impacted penguin populations, and the finding adds weight to this hypothesis because it "shows how robust penguin populations are where the ice is intact", Dr. Hart said.
"Despite our modern technologically advanced world there are still remote corners that we know very little about - usually because they are extremely hard to get to", he said.
