Emperor Penguin Colony In Antarctic Disappearing

London: The world’s second largest emperor penguin colony is disappearing in the Antarctic, a recent study showed. The colony at Halley Bay has suffered three years of almost total breeding failure, according to the study published in the journal Antarctic Science. In 2016 and 2017, low sea ice extent and early breakout of sea ice in spring resulted in complete breeding failure, reports Xinhua news agency. In 2018, the colony reformed, but with only a few hundred adults present at the breeding site, the study said.

Meanwhile, during the same three-year period, the nearby Dawson-Lambton colony, 55 km to the south, has seen a more than 10-fold increase in penguin numbers. The study said many of the birds from Halley Bay have relocated to Dawson-Lambton, with the rest remaining at Halley Bay, but not breeding successfully. The breeding failure and reasons for relocation are almost certainly linked to the early break-up of sea ice at the Halley Bay site, but the reasons remains unknown, the study said. However, scientists blame the sharp decline on climate and weather conditions for breaking apart the sea ice that’s connected to the land where the emperor penguins stay to breed. (IANS)
