World's 2nd largest emperor penguin colony disappeared overnight
April 25, 2019 16:38
The world's second largest emperor penguin colony is believed to have been effectively wiped out overnight, with thousands of chicks drowning when an ice shelf in Antarctica collapsed.
Since the catastrophic collapse of the ice sheet at Halley Bay in 2016, no breeding has been detected in the area, scientists say.
Usually 15,000 to 24,000 breeding pairs of emperor penguins flock each year to the breeding site -- around 5-9 per cent of the entire global emperor penguin population.
The bay in the Weddell Sea was previously considered a refuge for penguins in one of the coldest parts of the continent and which was expected to remain suitable for penguins this century despite climate change affecting Antarctic sea ice.
But almost no emperor penguins have been there since 2016, according to a team from the British Antarctic Survey, who used high-resolution satellite photographs of the birds' guano over time, to reveal the findings.
