Every year, along with the warm and longer days of Spring, the penguins arrive at the Patagonia coasts in the Chubut province.
Every September, Magellanic penguins return to the bleak shores near Punta Tombo to mate and raise their chicks.
The New York-based Wildlife Conservation Society has sponsored a penguin study for 16 years. Through banding, measuring and weighing the Punta Tombo penguins, and tracking their movements by satellite, researchers are learning how the penguins survive -- and how they die.
Fresh out of the nest, they are easy prey for foxes, armadillos and gulls.
Even if they make it out of the nest and enter the sea, most young penguins starve to death during their first year. Some conservationists blame overfishing by trawler fleets in the areas where penguins feed.
Another serious threat cited by conservationists is pollution from oil tankers, which repeatedly kills thousands of penguins along Argentina's coast.
While the law protects the penguins from being hunted by man, only international conservation measures can prevent them from being wiped out by other human activity, some experts say.
