Penguin poop spotted from space reveals hidden Antarctic colonies

the colonies are small and so only take the overall population count up by 5-10% to just over half a million penguins or around 265,500 – 278,500 breeding pairs,” Fretwell added.The majority of the newfound colonies are located at the “margins” of the species’ breeding range, meaning they are key locations likely to be lost as climate change worsens.”Whilst it’s good news that we’ve found these new colonies, the breeding sites are all in locations where recent model projections suggest emperors will decline,” said Dr. The new satellite images of Antarctica’s coastline have enabled us to find these new colonies,” lead author Dr. Emperor penguins (Aptenodytes forsteri) on sea ice at the Brunt ice shelf near BAS Halley Research Station.

Even in the best-case scenario based on current climate change trends, the population will decrease by at least 31% over the next three generations. The addition of 11 new colonies brings the global tally to 61 across Antarctica. Phil Trathan, the head of conservation biology at BAS. Get Breaking News Delivered to Your Inbox

Penguin colonies are notoriously difficult to study because they tend to be in highly remote and inaccessible regions with temperatures as low as minus 58 degrees Fahrenheit. A new study, published this week in the journal Remote Sensing Ecology and Conservation, reveals that a satellite spotted 11 new colonies of emperor penguins — nearly 20% more than previously thought. But it’s not all good news — the colonies are located in a region that is at a high risk of disappearing due to climate change. According to BAS, studies suggest that 80% of colonies will decrease by more than 90% by the end of the century if Antarctic sea ice diminishes by half.

Peter Fretwell, a geographer at the British Antarctic Survey (BAS), said in a press release.While the discovery is good news, the colonies are also extremely vulnerable to melting sea ice — their preferred breeding habitat.

“… Scientists said the findings help paint a clearer picture of the impact of climate change on the iconic bird.Images from the European Commission’s Copernicus Sentinel-2 satellite mission revealed penguin excrement stains on ice not previously seen, allowing researchers to find the new colonies. Aerial photographs and satellite imagery have long been used to locate colonies. Several were located far offshore, in shallow water, shifting scientists’ knowledge of the species’ behavior. The smudges on the ice show the existence of an emperor penguin colony. Climate Change
