The penguins of Punta Tomba, Argentina have been declining, not because they are suffering but because penguins are "“marine sentinels,” their decline is a message that their marine environment is in trouble, chiefly from over fishing and pollution from offshore oil operations and shipping". Dr. Boersma says. Their breeding pairs have declined 22 percent since 1987. These penguins can swim up to 100 miles a day, but now just to get enough food they have to swim more than 40 miles farther from their nests.
Dr. Boersma says that these birds lay up to 2 eggs, but if there is a food shortage than the parents usually favor the first hatched and often the other chick doesn't survive. Climate change dangers than more because about half nest in burrows that are vulnerable to flooding. Dr. Boersma wrote “we have entered a new era of unprecedented challenges for marine systems.”
