	Penguins in peril as food search turns into marathon http://apocadocs.com/s.pl?1234547127 Penguins from the largest colony on mainland South America are being forced to swim the equivalent of two marathons farther to find food because of the effects of climate change. The survival of the Magellanic penguin colony at Punta Tombo, on the Atlantic coast of Argentina, is being threatened by the increasing distances the birds must travel to feed themselves and their chicks, research has shown. Dee Boersma, of the University of Washington in Seattle, said that Punta Tombo penguins were now routinely swimming 25 miles farther on their foraging expeditions than they did a decade ago... The longer foraging trips have contributed to the colony's decline: penguin numbers have fallen by more than 20 per cent in the past 22 years, leaving only 200,000 breeding pairs today.
