Researchers recently attempted to count all of the Adélie penguins in Antarctica and found, to their own surprise, that the numbers of this white-eyed breed are exploding on the frigid continent, according to the Wall Street Journal. This contradicts claims by activists that the flightless bird is a victim of global warming whose dwindling numbers can be directly linked to dwindling ice caps. Wildlife biologists closely monitor Adélie penguins because their status correlates with annual sea-ice conditions and temperature trends.
But the Adélie population is actually 53 percent larger than previously estimated, having increased globally by 29 percent in two decades.
Heather Lynch of Stony Brook University, in New York, and imaging specialist Michelle LaRue of the University of Minnesota counted the birds by satellite and found that the Adélie penguin population is now 3.79 million breeding pairs, with 251 colonies.
The survey, published online this week by the American Ornithologists’ Union, coincides with another satellite census of Emperor penguins conducted in 2012 by geographers at the British Antarctic Survey that happened upon twice as many Emperor penguins as scientists had previously thought existed.
