They form huge colonies that can number in the hundreds of thousands and are located on hillsides as well as rocky cliffs. In South Georgia, macaroni penguins arrive to breed in late October and lay their eggs two weeks later. Females lay two eggs, the first much smaller than the second, and the smaller egg rarely hatches.
Both parents share incubating duties, but it comes at a great energy expense: Adult macaronis lose up to half their body weight in the process. The young macaroni chick fledges for two months after hatching, with just one parent staying at home to look after it. This focus on raising one chick means that the macaroni penguin population doesn't have the boom-bust population cycle like some other penguin species.
Macaroni chicks grow enough within 10 weeks to leave their parents behind and integrate into the adult penguin population. They live about 15 years in the wild. Because there's contention as to what distinguishes a rockhopper penguin , the species has been divided into three fairly distinct subspecies by reproductive behavior and breeding location: northern, southern, and eastern rockhopper penguin.
Rockhoppers are one of the smallest penguin species, and the smallest of the crested penguins, with an average height of 50 cm They usually stick to shallow water but can dive up to meters feet in pursuit of prey, which consists mostly of fish, krill, and small crustaceans. Rockhopper penguins get their name from their preferred habitat of rocky, windswept shorelines on the islands north of Antarctica.
During their annual breeding times, rockhoppers gather in chatty colonies that often number in the hundreds of thousands. They construct burrows in tall tussock grasses near shore, returning each year to the same breeding site, nest, and sometimes, the same mate. Magellanic penguins stand between 60 to 75 cm They tend to be shy around humans, running for cover in their nesting burrows if people are near. And if it gets too hot, they will shed beak feathers, pant, and stretch their flippers to catch a breeze and release excess heat.
Magellanic penguins are primarily found around the Falkland Islands and South America, where they are numerous, but scant vagrant populations have been recorded in South Georgia and the South Shetlands.
The Falklands population, in fact, is over , breeding pairs, but this is small compared to South America, where Magellanic penguins number around , breeding pairs in Argentina and , pairs in Chile. Magellanics like islands with dense vegetation and deep layers of soil for burrowing, which offers protection from aerial predators. Opportunistic feeders, Magellanics take equal proportions of fish, squid, and crustaceans. While out to sea, they usually forage at depths of less than 50 meters feet , but may at times dive up to meters feet.
King penguins are the second-largest penguin species after emperors: Once they reach full maturity, they weigh about 16 kg 35 pounds and stand 94 cm 37 inches tall. The estimated 2. They are the most marine of all penguins - and indeed all birds, spending more time at sea than any other. King penguins can dive to depths of more than meters feet to pursue prey, staying underwater for up to nine minutes.
They are highly social birds that gather in massive colonies like the St. Andrews Bay rookery of over , members to breed. King penguins have an unusual breeding timeframe that lasts approximately 14 months from courtship to the fledging of the chick. Not natural nest builders, king penguins instead lay one green-white egg that they incubate on their webbed feet and below a fold of skin.
King penguins are known by scientists to have mid-afternoon naps, sleeping more deeply after lunch than during the morning. They live to be about 25 years old in the wild. Ultimately, you just need to experience it in person. But if you still need convincing before you book an Antarctica cruise , check out the video below for some great shots and sounds of both species and scenery.
A riveting cosmic event only fully experienced along a narrow terrestrial pathway. PLA This Antarctic Peninsula and South Shetland Islands cruise delivers you into a landscape of dark rugged rock, pure white snow, and a fantastic variety of wildlife.
Come say hello to whales, seals, and thousands of penguins. HDS This cruise delivers you to wondrous landscapes found in one of the harshest environments on Earth. Meet the great stars of the Antarctic, the penguins, found in the thousands in a variety of curious species. This expedition allows you to hike, snowshoe, kayak, go mountaineering, and even camp out under the Southern Polar skies.
This species of penguin is found all around the South Pacific and Antarctic Ocean. The Emperor Penguin is breathtaking the first time you see one up close. These stunning creatures are both the tallest and heaviest of all penguin species, and are endemic to the Antarctic continent.
Emperor Penguins can thermoregulate their bodies - a convenient talent when you breed in the coldest environment of any bird species on the planet. Snow Hill Island on the east coast and the Dion Islands on the west coast are the most popular breeding areas to see the Emperor Penguins in Antarctica. Heading to South Georgia? The third largest penguin species can be found on many sub-Antarctic islands - the Falklands, South Georgia and the South Shetland Islands being the most popular for breeding colonies.
The Gentoo is another penguin species that is easy to identify by its distinctive white head markings. Fun fact: Gentoo penguins can spend their entire day hunting and can remain below water for an impressive seven minutes. With a name like Macaroni, you know this species of penguin has to be an interesting sort. These penguins have a very distinctive golden crest, making them easy to identify from the other Antarctic penguin species. The Macaroni is a great traveller and can be found everywhere from the sub-Antarctic islands to as far North as South Africa when foraging for food.
They also have established colonies on South Georgia and in Southern Chile. Last, but certainly not least, the Rockhopper penguin is the smallest species in the world and mostly lives on the islands of the sub-Antarctic peninsula. The main breeding colonies can be found in areas such as the Prince Edward and Crozet Islands, but the Rockhopper also frequents southern Chile, Argentina, and the Falklands.
A DNA test of a feather is the only sure way to know whether you have a male or female penguin. Another 4 species live on sub-Antarctic islands. Why live in Antarctica? How many people? Chinstrap penguins are named for the narrow black band under their heads. The largest of the penguin species, emperor penguins breed during the worst weather conditions on earth. King penguins are the second largest penguin and are close relatives of the emperor penguin.
Macaroni penguins have a circumpolar distribution, generally on sub-Antarctic islands. Southern rockhopper penguins. Southern rockhopper penguins are the smallest of the crested penguins.
