How to see a penguin in Antarctica? Play it cool

hose who come to McMurdo Station, the biggest U.S. science base in Antarctica, often dream of seeing the regal Emperor penguins or the smaller Adelies, but environmental policies require humans let the birds make the first move, and keep their distance in any case.

"If the animals are reacting to you, you're too close," is the general rule.

But sometimes penguins' curiosity brings them into close proximity with humans who are out in the penguin stomping ground, foraging for scientific data while the birds are foraging for food.
