England - Scientists have located dozens of colonies of emperor penguins in Antarctica, through the identification of large clusters of dung left behind by these birds, with images taken from space.

Satellite images show tasks giant red-brown on the pristine white ice, indicating the presence of thousands of penguins. This means that for the first time, researchers at the research center British Antarctic Survey (BAS) are able to locate each colony on the continent. The images have identified 38 settlements, 200,000 to 400,000 breeding pairs of emperor penguins.

Emperor penguins spend much of their lives in the sea during the winter, when temperatures drop below - 50 ° C, they return to their colony to breed on the ice. Until now it was difficult to follow and scientists could not precisely estimate their population, nor about the distribution of the different colonies.

Now they have a way to monitor them, researchers hope to monitor the impact of climate change threatens extinction of 95% of the population of penguins. Peter Fretwell, ABS, co-author of the study, said: "This is the first part of our ongoing study. Now that we can locate the colonies, we will be able to go further and precisely count the population.

Mr. Fretwell mapping an area near the research station Halley of BAS, on the platform Brunt in October 2008, when he noticed this on the ice through satellite imagery. "There is no other birds that breed on the ice and each colony of penguins can count tens of thousands of birds," he says.
