Each November, roughly one-fifth of the world’s Adélie Penguins collect to nest on seven craggy outcrops close to the tip of the Antarctic Peninsula. The Hazard Islands cowl simply 1.7 sq. miles however present breeding grounds for the world’s largest identified Adélie inhabitants—solely found a few decade in the past—plus no less than 9 different chicken species, together with Gentoo Penguins.
To guard them, Germany and the USA efficiently campaigned in 2024 to designate the Hazard Islands as an Antarctic Specifically Professionaltected Space. In late 2025, as a part of Germany’s new responsibility to handle the conservation zone, scientists there spearheaded a scientific expedition to the islands to check the penguins and rising threats—and attempt to get forward of them in order that the birds proceed to thrive.
Circumstances for penguins are altering quick.
Circumstances for penguins are altering quick: The Antarctic Peninsula is warming 5 occasions quicker than the worldwide common. As sea ice has dwindled, so have the shrimplike krill that anchor the Southern Ocean meals chain, together with for penguins. In flip, scientists have noticed Adélie Penguins declining in components of the peninsula. To guesster perceive how penguins could also be responding to those modifications, the expedition got down to acquire a extra exact rely of Adélies breeding on the Hazard Islands.
The staff additionally assessed the risk from avian flu, which reached Antarctic wildlife as early as 2023. Though the disease hasn’t but been detected in penguins, together with on the most recent mission, researchers are watching carefully. “Hundreds of thousands of penguins which can be so shut collectively might actually be heaven for a virus,” says Simeon Lisovski, a biologist on the Alfred Wegener Institute.
For a clearer image of how threats to their meals supply would possibly have an effect on penguins, the staff was additionally wanting to investigate the place the birds forage whereas rearing chicks. Lisovski and biologist Noell Heid glued satellite GPS monitoring gadgets to 22 Adélie Penguins. The gadgets will transmit the penguins’ positions each 10 minutes till they fall off—hopefully not till March, after the breeding season—permitting the staff to trace the birds remotely from Germany.
Alprepared some findings are elevating eyebrows. Of their pursuit of krill, some birds make weeklong journeys as much as 124 miles northward. This can be a surprisingly lengthy distance for penguin mother and father to journey, since their chicks want fixed feeding, says German Setting Company ecologist Fritz Hertel, who initiated the expedition.
Worryingly, it suggests that there’s not sufficient meals accessible close to the colony. For now, solely the Hazard Islands themselves are protected, not the encircling marine surroundings, which might depart penguin foraging areas in danger from overfishing. The staff plans to revisit the archipelago each different yr, and by 2029 Hertel and his colleagues hope to have gathered sufficient information to make a convincing case for expanded protections.
The Hazard Islands earned their identify for being hidden beneath thick pack ice, probably working ships aground. As sea ice has receded, the islands have change into extra accessible—however solely simply. The waters surrounding them are shallow and never nicely mapped. Most massive icebreakers can’t safely get shut, so the staff opted as a substitute for a nimbler sailboat, the Malizia Explorer. This gave them extra flexibility however made the wind and ice better hazards, forcing first mate Marin-Louis Moreau to generally spend hours on the mast looking for a secure pathway.
The scientists hunkered down inside, planning and ready for his or her alternative to climb ashore: In the long run, the circumstances allowed them solely 12 hours on land on the Hazard Islands. However throughout their temporary keep, they gathered important information and had been handled to “stunning climate and probably the most gorgeous surroundings and light-weight,” says photographer Esther Horvath, who focuses on polar exploration. “It was actually an adventurous scientific expedition.”
