They huddle together to escape wind and conserve warmth. Individuals take turns moving to the group's protected and relatively toasty interior. Once a penguin has warmed a bit it will move to the perimeter of the group so that others can enjoy protection from the icy elements. Emperor penguins spend the long winter on the open ice—and even breed during this harsh season.
Females lay a single egg and then promptly leave it behind. They undertake an extended hunting trip that lasts some two months! Depending on the extent of the ice pack, females may need to travel some 50 miles just to reach the open ocean, where they will feed on fish, squid, and krill. At sea, emperor penguins can dive to 1, feet—deeper than any other bird—and stay under for more than 20 minutes.
Male emperors keep the newly laid eggs warm, but they do not sit on them, as many other birds do. Males stand and protect their eggs from the elements by balancing them on their feet and covering them with feathered skin known as a brood pouch. During this two-month bout of babysitting the males eat nothing and are at the mercy of the Antarctic elements.
When female penguins return to the breeding site, they bring a belly full of food that they regurgitate for the newly hatched chicks. Meanwhile, their duty done, male emperors take to the sea in search of food for themselves. Mothers care for their young chicks and protect them with the warmth of their own brood pouches.
Outside of this warm cocoon, a chick could die in just a few minutes. In December, Antarctic summer, the pack ice begins to break up and open water appears near the breeding site, just as young emperor penguins are ready to swim and fish on their own.

How many emperor penguins are there today? Do emperor penguins have any predators? Seven essential emperor penguin facts Emperor penguins are the largest penguins in the world. They can dive deeper than any other bird, including other penguins. Emperor penguins do not build nests. Brood patches are flaps of featherless skin some birds have on the underside of their bellies. Like other penguins, emperors leap into the air while swimming, which is called porpoising.
This action coats them in micro air bubbles that help reduce friction underwater. Scientists think they might also just be doing it for fun. Emperors and other penguins have their distinct tuxedo look because, while swimming, their white bellies camouflage them against the light above, and their dark backs camouflage them against the depths below.
These are only penguins that breed during the Antarctic winter. Related cruises. Weddell Sea - In search of the Emperor Penguin, incl. Cruise date: 14 Nov - 24 Nov, Show cruise. Cruise date: 24 Nov - 4 Dec, They not only survive the Antarctic winter, but they breed during the worst weather conditions on earth.
Our research aims to learn more about the penguins how they live, where they go, what they do, and what they need to survive , and how human activities may impact on their lives and survival chances. The emperor is the largest of the 18 penguin species. Adults can weigh up to 40kg at the start of the breeding season.
Historically, there were some penguin species even larger than emperors, weighing perhaps kg! These mega-penguins became extinct several tens of thousands of years ago. Some emperors live to more than 40 years but most do not live that long in the wild. Their closest relatives are king penguins. Emperors have excellent insulation in the form of several layers of scale-like feathers — it takes very strong winds over 60 knots or about kilometres per hour to get them ruffled.
In proportion to their overall size, they have small bills and flippers to conserve heat. Their nasal chambers also recover much of the heat that is normally lost during exhalation. Emperor penguins have large reserves of energy-giving body fat and a relatively low level of activity during winter. They are very social creatures, and one of their survival mechanisms is to huddle together to keep warm.
This huddling instinct means that they do not defend any territory. The emperor penguin is the only species of penguin that is not territorial. Like other animals that live in the polar regions, special fats in their feet prevent them from freezing. Emperors have strong claws for gripping the ice. Emperor penguins breed in colonies scattered around the Antarctic continent. Colonies range in size from a few hundred to over 20, pairs. Most colonies are situated on the fast-ice that is locked between islands or grounded icebergs.
Conservation status: near threatened. Emperor penguin populations are projected to undergo a moderately rapid decline over the next three generations owing to the effects of projected climate change. Researchers are studying the influence of climatic changes on populations and how future environmental change may impact the species.
