Antarctic penguin colonies decline by as much as 77% in last 50 years

Ushuaia, Argentina – Scientists surveying chinstrap penguin colonies in the Antarctic have found drastic reductions in many colonies, with some declining by as much as 77% since they were last surveyed almost 50 years ago. 

The
independent researchers, on a Greenpeace expedition to the region, found that
every single colony surveyed on Elephant Island, an important habitat northeast
of the Antarctic Peninsula, had declined. The number of chinstrap penguins on
Elephant Island has dropped almost 60% since the last survey in 1971, with a
total count of only 52,786 breeding pairs of chinstrap penguins, plummeting
from previous survey estimates of around 122,550 pairs.

Campaigners
this week have been installing ‘disappearing’ penguin ice sculptures in
capitals around the world, from Seoul to London, Buenos Aires to Cape Town, to
demand urgent action to protect ocean wildlife with a Global Ocean Treaty. [See images

Dr Heather J. Lynch, Associate Professor of Ecology & Evolution at Stony Brook University, one of the expedition’s leads, said: “Such significant declines suggest that the Southern Ocean’s ecosystem is fundamentally changed from 50 years ago, and that the impacts of this are rippling up the food web to species like chinstrap penguins. While several factors may have a role to play, all the evidence we have points to climate change as being responsible for the changes we are seeing.”

Frida Bengtsson of Greenpeace’s Protect the Oceans campaign, said: “ A world with fewer penguins is a less happy place. As wildlife struggles, we urgently need sanctuaries free from harmful human activity not only in the Antarctic, but across the world’s oceans, so marine life like penguins have the space to recover from human activity and adapt to our rapidly changing climate. To do that, it’s imperative that governments agree on a Global Ocean Treaty this year.” 

The team
of scientists, from Stony Brook and Northeastern University, has also been
surveying a series of large but relatively unknown chinstrap penguin colonies
on Low Island, using manual and drone surveying techniques. This will be the
first time the island, thought to have around 100,000 breeding pairs of
chinstrap penguins, has been properly surveyed from land, with results to
follow.

Greenpeace has been campaigning for the establishment of three Antarctic
sanctuary proposals, which after being rejected in 2019, are due to be
discussed again at this year’s Antarctic Ocean Commission (CCAMLR) meeting in
October. These sanctuaries would offer protection for many of the colonies
being surveyed.
