Editing Adélie penguin (section)

===Threats===
Adult Adélie penguins are regularly preyed upon by [[leopard seal]]s. [[South polar skua]]s, in particular, and [[giant petrel]]s kill many chicks and eat eggs as well. Giant petrels and [[orca]]s will occasionally kill adult Adelie penguins. [[Kelp gull]]s and [[snowy sheathbill]]s also prey on chicks and eggs.<ref>{{Cite web|url=https://www.britannica.com/animal/Adelie-penguin|title=Adélie penguin {{!}} bird|website=Encyclopedia Britannica|language=en|access-date=2019-02-25|archive-date=25 February 2019|archive-url=https://web.archive.org/web/20190225104715/https://www.britannica.com/animal/Adelie-penguin|url-status=live}}</ref>

In 2024, researchers from [[Federation University Australia]] reported more than 532 dead Adélie penguins on Antarctica's [[Heroína Island]], with the [[Influenza A virus subtype H5N1|H5N1]] bird flu suspected as the cause. The virus, having arrived in [[South America]] in 2022, poses a risk to Antarctic wildlife. Samples from the deceased penguins are under analysis, and the H5 strain has been detected in local [[skua]] seabirds, potentially facilitating further spread. This situation is particularly concerning for the wildlife of the region, which includes an estimated 20 million pairs of penguins and the already climate-threatened [[emperor penguin]]s.<ref>{{Cite news |last1=Spring |first1=Jake |date=2024-04-04 |title=Scientists investigate thousands of dead Antarctic penguins for bird flu |url=https://www.reuters.com/business/healthcare-pharmaceuticals/scientists-investigate-thousands-dead-antarctic-penguins-bird-flu-2024-04-04/ |access-date=2024-04-07 |work=Reuters |language=en}}</ref>
