King Penguins Adapt to Warming World

A new study published in Science Advances, co-authored by Celine Le Bohec from Institut national de la recherche scientifique and led by Gaël Bardon from Scientific Centre of Monaco, found that king penguins are adapting to a warming world by breeding 19 days earlier than in 2000, increasing their breeding success rate by 40%. This adaptation is considered unprecedented among birds, as most species, particularly in North America, are not keeping pace with phenological changes, according to Casey Youngflesh of Clemson University. The king penguins' flexibility in diet and foraging behavior allows them to cope with changing food webs. However, scientists like Michelle Bachelet from University of Canterbury and Ignacio Juarez Martinez from University of Oxford caution that this may only be a temporary adjustment, and future climate changes could undo these gains.
