Recently, more than 1,500,000 Adélie penguins a “super-colony” was found on the Danger Islands, a chain of remote, rocky islands off the Antarctic Peninsula’s northern tip has been founded by the researchers. From the past 40 years, the total number of Adélie penguins, one of the most common species of penguins live on the Antarctic Peninsula has been steadily declining or so biologists thought. These penguin super colonies have gone undetected for decades, partly because of the remoteness of the islands themselves, and of the treacherous waters that surround them. During the summer also, the nearby ocean is filled with thick sea ice fills, making it extremely difficult to access. In 2014, scientists discovered telltale guano stains in satellite imagery of the islands, implying at a strangely large number of penguins. Researchers arranged an expedition to the islands in December 2015 to find out it definitely and found hundreds of thousands of birds nesting in the rocky soil. They counted the birds and also used a modified commercial quadcopter drone to take images of the entire island from above. The number of penguins in the Danger Islands could provide insight not just on penguin population dynamics, but also on the effects of changing temperature and sea ice on the region’s ecology. By getting the accurate count of the birds in this super-colony offers a significant benchmark for future change.
