Penguin Colony Loses Two-Thirds of Nests
Antarctic chinstrap penguins lost nearly two-thirds of nests since 2011 due to ocean warming.
In brief
Antarctic chinstrap penguins lost nearly two-thirds of nests since 2011 due to ocean warming. Zavodovski Island's chinstrap penguin colony lost 63% of nests since 2011 as ocean warming shifts krill populations. Originally reported by MercoPress.
Zavodovski Island
The world's largest penguin colony lost its title after a study found 63% fewer occupied nests since 2011.
“The island, described that year as the world's largest penguin colony, has lost that title.”
Ocean Warming Cause
Researchers attribute the decline to ocean warming shifting krill populations southwards, preventing penguins from following food.
“With waters warming, the krill the chinstrap penguins eat have moved southwards.”
Penguin Population Shift
Chinstrap penguins may now be officially endangered as macaroni penguins increased due to warmer foraging waters.
“The researchers believe the species may now qualify as officially endangered.”
In short
Zavodovski Island's chinstrap penguin colony lost 63% of nests since 2011 as ocean warming shifts krill populations.
