뉴질랜드에서 죽은 리틀 블루 펭귄이 계속 해변으로 밀려옵니다.. 전문가들은 기후 변화가 책임이 될 수 있다고 말합니다.

The bodies of hundreds of little blue penguins have washed up on the beaches of New Zealand’s northern coast in recent weeks, 환경 보호론자들에 따르면, 기후 변화를 두려워하는 사람들은 새들을 굶어 죽게 만들고 있습니다..

The kororā, also known as little blue penguins, are native to New Zealand but areat-riskof declining, according to the country’s Department of Conservation. They face predatory threats from dogs and ferrets but are also susceptible to road deaths and coastal developments.
Conservationists have been trying to find out why the penguins have been dying en masse since early May, when residents first spotted the dead birds on beaches.
    Graeme Taylor, a principal science adviser who studies sea birds at the New Zealand Department of Conservation, said based on initial lab results malnutrition may be the cause of death of between 200 과 500 of the birds.
      The cause of the mortality event seems to be from failure to find sufficient food at sea and dying from starvation,” Taylor told CNN.
        A marine heatwave in the country’s northern waters coupled with the natural La Niña weather cycle conditions have made it harder for the little blue penguins to find food, 테일러가 말했다.
        The small, noisy birds with pale blue or indigo feathers typically eat anchovies and sardines, usually diving to depths of up to 30 미터 (약 100 피트) to catch their prey. But rising water temperatures mean the small fish are moving to colder waters too deep for the birds to reach, 테일러가 말했다.
          Initial findings from a Ministry of Primary Industries necropsy study showed the birds had lost their abdominal fat pad, so were in poor health before drifting to shore.
          New Zealand experienced its warmest year on record in 2021, with annual temperatures hovering 0.5 ...에 1.2 degrees Celsius higher than normal, according to the National Institute of Water and Atmospheric Research.
          Waters surrounding the countryhave been pulsing up to 3 degrees Celsius recently,” New Zealand Climate Change Research Institute adjunct senior research fellow Nathanael Melia told CNN affiliate Radio New Zealand in January.
          La Niña is a regular oceanic and atmospheric phenomenon that refers to the periodic cooling of ocean temperatures in the central to east-central equatorial Pacific. The current phase of the cycle is bringing warmer water to northern New Zealand which makes it harder for little blue penguins to access food, according to Taylor.

          Not a new problem, but getting worse

          Dave Houston, an ecologist at the Department of Conservation, said this isn’t the first time the birds have died in large numbers.
          Back in the 1970s, 80s and 90s [we had] 까지 5,000 birds in these mass die-off events,” Houston said. “Compared to past events, this is relatively small.
          지금까지, penguin deaths have been reported in the country’s North Islandwhere cases have happened in the pastand none have been flagged in the South Island.
          While Houston said the phenomenon is part of a naturally occurring cycle, he admitted that climate change had exacerbated its negative effects.
          “우리는 알고 있습니다 [little blue penguins] can survive in warmer waters, but it has made life difficult for them,” 그는 말했다.
            Bruce McKinley, president of Birds New Zealand, said climate change and pollution might make things worse in the future.
            The event itself is natural and has happened before, it could be changing in the pattern or the intensity due to warming of oceans because of human-induced climate change. But we just don’t know,” McKinley said.
