Population of Adelie penguins grows

Heather Lynch, an assistant professor at Stony Brook, and another researcher, made an interesting discovery about Adelie penguins in the Antarctic: There are a lot more of them than people thought. Their findings are based on 10 months of reviewing hi-res satellite images looking for penguin excrement, which indicates how many breeding pairs are in an area.
