In 2019, researchers used Sentinel-2 satellite images to find eight unreported emperor-penguin breeding colonies, lifting the known total to 61

Eight new emperor penguin colonies have been identified in Antarctica, increasing the total to 61 active populations. The British Antarctic Survey made this discovery using satellite imagery to detect guano stains on sea ice. This finding raises the estimated population to over 500,000 birds, but the new colonies are small and vulnerable. Most colonies are located in areas predicted to lose ice early due to climate change.
