There are no materials to build nests. Emperor penguins breed and lay their eggs on ice. But, like the eggs of any species, they must be kept warm. Once the female lays her eggs—she leaves the colony to go searching for food, and is often gone for two to four months. Before she does so, she transfers the egg to her male partner who tenderly puts it on his foot and covers it with its skinfold, a warm layer of feathered skin often called a brood pouch.
With the mother gone for an extended period in search of food, how does Emperor penguin egg hatching actually take place? As explained above, the male has custody of the egg in its skinfold—but how is he able to survive? He consumes no food while incubating the egg, but relies on the body fat he has accumulated over the summer period. You can learn more about the survival rates of Emperor penguins in this helpful infographic. Interestingly, thousand-fold rookeries of penguins have devised a sociable way of maintain body heat to protect and keep their eggs warm during the nesting period.
Unlike some other penguin species which are known to bicker and compete for nesting space, Emperor penguins will form a communal huddle—in the hundreds and thousands—to keep warm. They shuffle around so each Emperor penguin takes its turn on the colder outer edges of the huddle and then works his way into the warmer centre, each male taking its turn.
The female arrives back around August in time for the chicks to hatch. She will take over feeding the chicks, allowing the male to head off in search of much-needed food. Both parents rear the chick together. Unlike some other penguin species, the Emperor penguins are known for their communal living habits, both for safety and for heat preservation when males are incubating the eggs.
The team of polar experts at Quark Expeditions—which leads the way in conducting visits to the famous Emperor penguin rookery—has identified October or November as the best month to visit Antarctica to see Emperor penguins on Snow Hill Island.
In , Quark Expeditions scheduled four trips to see Emperor penguins during the period of October to November, which they determined the best times to see Emperor penguins in Antarctica. The timing of these trips is based on a number of factors—including weather and ice conditions.
However, Quark Expeditions has succeeded by bringing into its fleet the legendary Russian vessel Kapitan Khelbnikov , the famous ice-strengthened ship that has circumnavigated Antarctica twice and the Arctic once. This was was the first ship ever to successfully bring travelers on trips to see Emperor penguins in Antarctica.
Quark Expeditions made its first successful landing at the famous Emperor penguin colony in At time of writing, no trips are scheduled — but stay tuned to our Snow Hill Island expedition page for information when trips to see Emperor penguins become available. In meantime, you can fulfill your desire to see penguins in Antarctica by exploring other scheduled trips, such as South Georgia and Antarctic Peninsula: Penguin Safari and Crossing the Circle: Southern Expedition. A love of nature and writing has enabled Doug O'Neill to visit almost 50 countries around the world—and to immerse himself in some of the most incredible nature settings.
Doug's role as Brand Copywriter at Quark Expeditions has been a natural step on a journey that started with a degree in Environmental Studies and later a Certificate in Journalism. During this time he does not eat at all, and survives on fat stored in his body. When the egg hatches, the male begins to feed the chick, before the female returns. She swaps place with the male and takes over caring for the chick.
Then the male penguin heads out to sea to eat for the first time in four months. As penguin chicks grow up, their parents start leaving them to go and feed in the sea. They generate two types of sounds to communicate at different frequencies. The first is short and used for long distances, and the other is long and used when they are only a few meters away. Distress calls consist of repetitive sounds and body movements such as beak lifting, stretching the neck and taking an aggressive posture.
The molting period lasts about 35 days, and during that time they cannot dive into the ocean. When they finally manage to discard all the plumage of birth, they are ready to hunt at sea and continue their life cycle. Fish, squid, and krill provide enough protein and nutrients that emperor penguins need to replenish their energy. During the breeding season, females go as far as miles away from the mainland while males move away only half of that distance.
Normal clutch: One egg. The breeding season starts during the month of April when the march towards the nesting colonies, completely away from the coast, begins. At a walking pace of 1 mph usually, they arrive at their destination on the third day.
One of the riskiest parts of their reproduction process is when the female has to transfer the egg to the male. This procedure has to be done very carefully because any fail in the process, any sudden or wrong movement could cause the egg to fall into the ice, freezing the egg within seconds and killing the offspring.
Once the father has the egg and starts protecting it, the female returns to the sea to feed and returns to the colony almost after two months, but before the hatchling breaks the large and thick shell of its egg. The mothers keep part of the food they got in their stomach, which regurgitate to feed their newborn chick. Once the mother appears, the father finally goes back to the ocean for food after all that time. Parents take turns six times, walking that distance, in search of food that their hungry chicks loudly request.
