In the first complete survey of chinstrap penguins' breeding across Deception Island in the Antarctic, scientists have found a significant number of the chic birds have disappeared from the breeding grounds since the 1980s.
The largest colony, called Baily Head on Deception Island, which is located in the Antarctic's South Shetland Islands, saw a drop of more than 50 percent over the past two decades, the researchers added.
The culprit? The scientists point to climate change.
The study, detailed this week in the journal Polar Biology, complements another recent tally of chinstrap penguins on Deception Island. That survey focused on just one chinstrap colony on Deception, showing that more than one-third of the Vapour Col colony had vanished in the past 20 years.
