Penguins are bringing forward their breeding season at record rates as Antarctica rapidly warms due to climate change, according to research published by a global team of scientists.<\/p>\n
The unprecedented shift observed over a decade in penguin breeding patterns was “highly correlated” with rising temperatures on the frozen continent, said the study’s lead author Ignacio Juarez Martinez.<\/p>\n
Penguin breeding is closely linked to food availability, and less sea ice has meant hunting grounds and nesting sites are more available during the year.<\/p>\n
Scientists observing penguin populations in Antarctica had expected breeding to occur a little earlier but were “very surprised both by the scale and the speed of the advance”, Mr Martinez, a scientist from the University of Oxford and Oxford Brookes University, said.<\/p>\n
“The scale is so great that penguins in most areas are now breeding earlier than in any historical records,” he said.<\/p>\n
For this study, scientists observed nesting zones of Gentoo, Chinstrap and Adelie penguins between 2012 and 2022 using dozens of timelapse cameras placed at colonies across Antarctica.<\/p>\n
Gentoo penguins demonstrated the greatest change with the timing of their breeding season brought forward 13 days over the decade – and up to 24 days in some colonies.<\/p>\n
This is the fastest change in breeding season observed in any bird – and possibly vertebrate – to date, the scientists said.<\/p>\n
Adelie and Chinstrap penguins also advanced their breeding season by an average of ten days.<\/p>\n
The findings were published in the Journal of Animal Ecology.<\/p>\n
Antarctica is one of the fastest-warming regions in the world and annual average temperatures there reached record highs last year, the EU climate monitor Copernicus said this month.<\/p>\n
The exact mechanisms by which rising temperatures affect penguin behaviour are not yet fully understood by scientists.<\/p>\n

The three species traditionally staggered their breeding seasons but the earlier timing was likely causing an overlap, increasing competition for food and snow-free nesting space.<\/p>\n
This was better news for Gentoos – natural foragers suited to more temperate conditions – and less so for Chinstrap and Adelie penguins.<\/p>\n
“We have already seen Gentoos take nests that were previously occupied by Adelies or Chinstraps,” said Mr Martinez.<\/p>\n
Gentoo numbers are already expanding in a milder Antarctica while Chinstrap and Adelie penguins, more dependent on krill – tiny shrimp-like creatures on which they feed – and specific ice conditions, are declining.<\/p>\n
“As penguins are considered ‘a bellwether of climate change’, the results of this study have implications for species across the planet,” Fiona Jones, a co-author of the study from Oxford University, said in a statement.<\/p>\n
Mr Martinez said it was “too early to tell” if this adaptation was beneficial or if penguins were being forced to make drastic changes that could affect their breeding success.<\/p>\n
“We are now studying their ability to raise chicks of each species. If they maintain a high number of chicks, that will mean this is good news and they are indeed adapting to climate change,” he said.<\/p>\n","protected":false},"excerpt":{"rendered":"Penguins are bringing forward their breeding season at record rates as Antarctica rapidly warms due to climate change,…\n","protected":false},"author":2,"featured_media":254334,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[22],"tags":[246,61,60,82],"class_list":["post-254333","post","type-post","status-publish","format-standard","has-post-thumbnail","category-environment","tag-environment","tag-ie","tag-ireland","tag-science"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/254333","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/comments?post=254333"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/254333\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media\/254334"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media?parent=254333"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/categories?post=254333"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/tags?post=254333"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
