Over a few months, the penguins – depending on the size of the colony – can cover an area of several square kilometres with guano! Researchers from the UK, USA and Australia used satellite images to estimate the size of the global population of emperor penguins (Fretwell et al. The colony at Auster has about 12,000 breeding pairs while there are about 3000 breeding pairs at Taylor Glacier.
Taylor Glacier is an Antarctic Specially Protected Area (ASPA) and special permits are required to enter the area. Fretwell and colleagues totted 595,000 penguins, which is almost double the previous estimates of 270,000-350,000 emperors.

Scientists have discovered 9,000 emperor penguins living together in a hidden colony in Antarctica. A hidden colony of emperor penguins in Antarctica has been snapped for the first time by human visitors.
There's as many as 9,000 penguins living together on the frozen continent's Princess Ragnhild Coast.
Scientists from the Britain and the US were able to work out the birds' location after spotting traces of the penguin's poo on satellite images. Now three experts from Belgium's Princess Elisabeth Antarctica polar research have become the first people to visit and photograph the colony.

This is partly because they decided a long time ago to live in one of Earth’s most inhospitable environments. The males take over the egg from their mates, put it on top of their feet and cover with a skin fold of their bellies. Thankfully today’s satellites have a high enough resolution to pick up these patches.
But we in the Australian sector of Antarctica are lucky since two emperor penguin colonies are relatively close to one of our Antarctic bases, Mawson Station. A second one, at the Dion Islands, at the Antarctic Peninsula has probably ceased to exist.
The count is thought to be the first comprehensive census of a species taken from space.Co-author Michelle LaRue from the University of Minnesota said the monitoring method provided "an enormous step forward in Antarctic ecology". Expedition leader Alain Hubert described finding the penguins as 'an unforgettable moment'. Also, the penguins breed throughout the Antarctic winter and most of the colonies we know are situated on fast ice (frozen sea attached to the Antarctic continent). But when the worst weather is over the colony spreads out, shifts location, the huddles reform during the next blizzard. At a number of other colonies where small islands are near their breeding area, emperor penguins often climb ashore in early summer.


Many of the now known 46 colonies have either never been visited by people or have not been visited for a very long time. A few seasons prior to this work, scientists visited some emperor penguin colonies and conducted ground counts of the penguins.
Accurate monitoring of population trends is critical to understanding the ongoing rapid changes in Antarctic ecosystems. However, the remoteness and logistical complexity of operating in Antarctica, especially during winter, can make such an assessment difficult.
That means that the numbers from the ground counts, which are quite accurate, were compared to counts made of the satellite images and compared. Satellite imaging is being increasingly recognized as a valuable method for remote animal population monitoring, yet its accuracy and reliability are still to be fully evaluated.In this study, the authors report on several successive remote surveys in the coastal region of East Antarctica, both before and after sudden local changes.
Additionally, they describe the first ground visit of an emperor penguin colony initially discovered by satellite.The ground survey resulted in the discovery of a second penguin colony not indicated by satellite survey. The researchers found that these two colonies, with a total of ~ 7,400 breeding pairs, are located near the Mertz Glacier in an area that underwent tremendous habitat change after the glacier tongue broke off in February 2010. The authors suggest these penguins have considerable potential for rapid adaptation to sudden habitat loss, as the colony detected in 2009 may have moved and settled in new breeding grounds.
