Scientists have documented a dramatic decrease in the storm petrel penguin population on Zavodovski Island, a British island in the South Atlantic Ocean. In 2011, the island hosted 900,000 storm petrel penguins and 90,000 macaroni penguins. A recent study revealed a 63 percent decline in storm petrel penguins over the following fourteen years, while the macaroni penguin population increased. Researchers from the British Antarctic Survey (BAS) attribute this alarming trend to climate change, specifically the warming of the waters which has pushed their primary food source, krill, further south. Unable to follow due to sea ice and lack of nesting sites, the storm petrels are struggling to find sustenance. The resilience of macaroni penguins is likely due to their more diverse diet including fish and shellfish, while other potential causes like volcanic activity on Zavodovski Island and competition from other krill predators were ruled out.
