Gentoo Penguins Discovered On Antarctic Peninsula - Moving South As Ice Melts, Seas Warm

The crew of the M/V Arctic Sunrise, an icebreaker vessel owned by Greenpeace, were sailing through Antarctica’s Weddell Sea this month when they saw something they didn’t expect. “One of the scientists on board, Alex Borowicz … was looking through the binoculars from the bridge of our ship,” Louisa Casson, an ocean campaigner with Greenpeace UK currently on board the Arctic Sunrise, told Mongabay in a video interview. “He spotted what he thought looked like a penguin colony, where we had seen no previous records.”

As the ship drew near, the crew discovered a colony of gentoo penguins (Pygoscelis papua) consisting of about 75 chicks living on Andersson Island on the east side of the Antarctic Peninsula, previously unknown to science. Scientists say this is the furthest south the species has ever been seen in this part of Antarctica, and posit their presence here to the impacts of climate change.

“It’s may be a cliché at this point, but they’re the canary in the coal mine for climate change because they’re so closely tied to those sea ice conditions,” Heather Lynch, an Antarctic penguin expert at Stony Brook University in New York and the remote leader of the expedition, told Mongabay in a video interview. Gentoo penguins are generally found across the sub-Antarctic region, with the largest colonies on the Falkland Islands, South Georgia and parts of the Antarctic Peninsula. Unlike other penguin species that migrate to feed or breed, gentoo penguins will stay in the same place in both summer and winter, so conditions have to be ideal for them to survive year-round in a given location.
