Unlike their cold-weather relatives, Humboldt penguins live only in South America, along the rocky Pacific coast of Chile and Peru.
The Saint Louis Zoo’s Michael Macek has been monitoring the penguins there, tracking their health and numbers.
Macek is back in Peru again, in a coastal reserve called Punta San Juan, where Humboldt penguins nest by the thousands.
Before he left, he told St. Louis Public Radio's Véronique LaCapra that this time he’s helping to lead a sustainable guano harvest.
In the weird and wacky news category today, at least one penguin at the St. Louis Zoo appears to be a feisty opponent of Newt Gingrich - or at least one of his fingers.
The Republican presidential candidate is sporting a small bandage on his finger after getting nipped by a small penguin during his tour of the zoo on Friday. Gingrich was in St. Louis to speak during the National Rifle Association's annual meeting.
