Brown or Antarctic Skua

A heavyweight skua that muscles in on other species' food!

Information about Brown or Antarctic Skua

Our Expert Says… "Like many opportunistic species, skuas show intelligence in their behaviors. They look out for inexperienced penguin parents who may be squabbling over nesting stones and grab eggs while they are distracted. Although creching helps protect the older penguin chicks, again skuas have been seen deliberately chasing the creche, looking for any chicks that are weak or injured that they can pick off."

The Brown Skua is also known as the Antarctic Skua, Subantarctic skua, or Falklands Skua! There is some controversy among naturalists about whether these are distinct species or not, but as the debate is very technical and rather scientific we will just leave them to it and talk about this commonly-encountered Antarctic bird.

Although not particularly large in terms of length or wingspan, the Antarctic skua is a heavy bird, weighing in on average at more than 1.8kg (4lb). They use this weight to good effect, often stealing food from other species. Rather like gulls, they have a varied diet that includes fish, scavenged carrion, eggs, and most infamously, penguin chicks (as well as chicks of other seabirds).

Undoubtedly intelligent (a study in 2016 showed they could recognize different individual humans, for example) they are opportunistic and very often be seen close by penguin rookeries during the breeding season. They wait for the moment when a nest is left and pounce on the unattended eggs or chicks, using their large muscle mass to fly quickly away with their hapless prey clutched in their powerful bill.

One of the reasons penguins may abandon their chicks is due to disturbance (either by predators or by people). It’s for this reason that your expert Antarctic naturalist guides will always ensure that your shore excursions don’t disturb any nesting species.

You’ll find good populations of brown or Antarctic skuas on South Georgia Island, the Falklands, and throughout the subantarctic islands and antarctic peninsula.

Interesting facts about Brown or Antarctic Skua

It is very important to keep to the right distance from penguin colonies - 5 to 10m according to the location, and slow down on your approach

If a penguin is nervous of your approach it might site up quickly and a skua nearby can pounce and grab an egg in less than two seconds, or grab a chick. You do not want to be responsible for that outcome.

Curiously, on Port Lockroy, the most visited location in Antarctica, breeding Gentoo Penguins do slight better where guest are allowed, compared to off limit areas. Some even nest right next to the entrance. It is thought penguins are awake and inquisitive when guests are around, but sitting tight on the nest. At other times, if they are sleeping, there might be times when an egg or chick is partially exposed, a potential target for the skuas!

Highlights where the Brown or Antarctic Skua can be seen

Bleaker Island

Bleaker Island (known as Isla Maria in Spanish) has had at least 3 changes of the name since the Falkland Islands were first discovered and colonized.

It was first named Long Island - a rather unimaginative title because that’s what it is, long and thin. Its name was changed to Breaker Island and it appeared like this on maps and charts until 1859, when a new chart was published with the name changed to Bleaker. What was probably a printing error has stuck ever since!

There was evidence that sealers had been using Bleaker Island as a base, but there was no permanent settlement attempted until 1880 when a house was built and a sheep farm set up. The island has been used for rearing ship ever since, and now has some cattle as well. It’s run as an organic farm and tourist destination, with stewardship of the land to allow both commercial farming and wildlife preservation at its heart.

A formally-designated Important Bird Area (or IBA), Bleaker Island is home to a large breeding colony of Imperial Cormorants more than 16,000 strong. Other species to be found here include Gentoo penguins who nest on the appropriately-named Penguin Hill above Sandy Bay. There are also Southern Rockhopper penguins to be found near Long Gulch and Magellanic penguin burrows are widespread.

There are also many smaller bird species here, including Falklands grass wrens and pipits, black-chinned siskins, and dark-faced ground-tyrants. There are also some birds of prey including southern caracaras.

Elephant Island

Elephant Island is one of the outermost of the South Shetland Islands. The roots of its name are argued to be one of two reasons. Either the fact that Elephant seals were seen hauled out here in large numbers by the first person to discover and map the island, Captain George Powell in 1821, or that the island’s shape is uncannily like that of a baby elephant’s head with trunk extended!

The island remained unexplored for many years thanks in part to its lack of resources (just small numbers of seals and penguins and no native plants) and partly because of its steep volcanic rocks, presenting few landing points.

However, in 1916 Elephant Island became immortalized as the scene of the beyond-all-odds survival story that was Ernest Shackleton’s ill-fated Antarctic expedition.

After their ship Endurance was lost to the treacherous ice in the Weddell Sea, the 28 crew were forced to make a perilous escape attempt. After months in open boats and stuck on drifting ice sheets, the team arrived at Elephant Island. Here they set up a base to stay at Point Wild while Shackleton and five members of his crew set sail in an open lifeboat for South Georgia - a journey of over 800 miles - to seek a rescue ship.

This stunning tale of endurance, determination, and the human spirit is brought home to visitors to Elephant Island by the Endurance Memorial at Point Wild. You can also see breathtaking views of the Endurance Glacier - named after Shackleton’s lost ship - as well as the stunning rocky terrain and its Chinstrap Penguins and seals.

Half Moon Island

Half Moon Island is rugged and rocky and lies just off the Bergas Peninsula in the South Shetland Islands and it is a very popular spot as the either the first or last landing on an Antarctic Peninsula cruise. One side of Half Moon Island has steep, scree-covered slopes and cliffs down to the water, an ideal home to many Antarctic sea birds. The other parts of the island are characterized by pebble and boulder beaches leading to shallower slopes.

Visitor numbers are strictly controlled to ensure that the resident terns, gulls, and penguins aren’t disturbed, especially during their breeding seasons.

Your landing site is a cobbled beach where the remains of a whaling dory (a type of shallow, planked boat) can be seen.

As well as penguin colonies close to the shore, your Antarctic exploration guides will show you the Half Moon Island chinstrap penguin nesting sites near a navigation tower at the top of the hill, as well as the amazing Wilson’s Storm Petrel burrows that have been dug into the scree slopes here. Half Moon has also had a lone Macaroni penguin for a number of years, and others occasionally turn up here.

Your guides will also show you the areas where you can roam freely, always keeping an eye out for Fur Seals whose colors camouflage themselves against the rocks.

Half Moon Island is also home to the Argentinian Summer Antarctic Research Station. You may well spot scientists undertaking important surveys and research work during your visit.

The is also the stunning backdrop of the snow covered and rugged Livingstone Island with the tumbling glaciers.

Paulet Island

Paulet Island is a striking sight. This circular rock is only 1 mile in diameter, yet it has a volcanic cone that rises to over 1100 feet at its center. It’s found about 3 miles from Dundee Island at the northern end of the Antarctic Peninsula.

First mapped in 1839, Paulet Island is home to a huge penguin colony. Some 100,000 breeding pairs of Adelie penguins live here, a truly remarkable sight and sound! You will also see other sea birds on your visit, including shags, snow petrels, and kelp gulls.

Another fascinating aspect of Paulet Island is the historic shelter that dates back to 1903. The expedition ship on the Nordenskjöld expedition - the Antarctica (after which the Antarctic Sound is named) - was crushed by the ice pack, and survivors of the wreck reached Paulet built a stone hut to shelter them from the harsh winter conditions. There is also a cairn built on the highest point of the island that they used to attract attention for any rescue. There is also a grave marker for one expedition member who sadly did not survive.

Because Paulet Island is so densely packed with wildlife, visitors will be escorted in small groups by experienced Antarctic guides. This ensures that the breeding birds are disturbed as little as possible and that the shelter site is protected.

Fur seals are often also seen on the shores here. In the peak breeding season, you may find that some of the walking trails around the island are closed due to the sheer numbers of wonderful creatures that choose to raise their young here.

Port Charcot, Booth Island

Port Charcot is a small bay at the north end of Booth Island. Booth Island is a rocky and rugged Y-shaped island off the Kiev Peninsula in Graham Land. It was first mapped in 1904 when the French Antarctic expedition led by Jean-Baptise Charcot over-wintered here.

After building a few rudimentary shelters and the cairn that can still be seen at the top of the hill, the expedition used Port Charcot as its base for exploring the area, that is close to the Lemaire Channel and the division between the NW and the SW peninsula . There is the remains of a stone hut used for astronomical observations and a wooden pillar with a plaque here where you can still make out the names of the first expedition members who wrote them almost 120 years ago.

In the bay where the Français was anchored (but difficult to reach with the ice) the letter 'F' was carved onto the rocks and can still be seen.

The walk to the cairn is delightful, although you’ll be carefully led by guides as wandering off the path can be treacherous, with loose rocks and crevasses. Visitors can also walk to the east where there is a noisy Gentoo penguin colony. Chinstraps and Adelies can also be seen on the beaches here. If you are lucky, you might get all three together!

From the top the views are stunning, especially the view to the SW, towards Pléneau Island Island, overlooking 'the iceberg graveyard'. This iceberg graveyard can be explored on a spectacular Zodiac cruise, either from ships anchored off Port Charcot to the 'NW' of the Lemaire Channel, or from ships anchored off Pléneau Island and Booth Island that had sailed through through the Lemaire Channel. For full details of this Zodiac cruise refer to the details under Pléneau Island.

Prion Island

Prion Island, like many places in the Antarctic, was named after what was first seen there. In this case, during an expedition of 1912, the island was named because the naturalist Robert Cushman Murphy noted the large numbers of prions he found here.

The prion is a small petrel also sometimes known as a whalebird, and they get their unusual name because of their saw-tooth bill - the word prion in greek means “saw”.

Prion Island sits in the 9-mile-wide Bay of Isles off the northern coast of South Georgia. It is only 1.5 miles in length but it has been designated a Specially Protected Area in its entirety. Because it has always been rat-free, birds can raise their young here without fear of their nests being raided by non-native scavengers. Because of the need to protect the wildlife, there are strict restrictions on visitor numbers, and only 50 people per day are allowed ashore during the season when Prion Island is open to visitors, so guests are often split between going ashore, doing a really good Zodiac cruise, and sometimes with being onboard ship. You’ll also find that your naturalist guides will ensure that no one is carrying anything on to the island that could harbor an invasive species.

To protect the native flora and to avoid damage to petrel and prion burrows, the South Georgia authorities have built a boardwalk, and you will be required to stay on it at all times during your visit. Don’t worry, though, as the animals seem to have decided that they enjoy using it too and nest and feed right up to its edge, so you’ll have plenty of close encounters!

Another important species that breeds here is the wandering albatross. Indeed, Prion Island is such an important breeding center for them that the whole island is closed to visitors between 20th November and 7th January each year to allow them to pair off without disturbance. This time also coincides with the breeding season for Antarctic fur seals who also benefit from the seclusion.

Other species you can find on Prion Island include South Georgia Pipits and South Georgia Pintails, snowy sheathbills, skuas, Antarctic terns, and gentoo penguins.

Saunders Island

Saunders Island (known in Spanish as Isla Trinidad) is in the northwest of the Falkland Islands group and is the 4th largest individual island with 50 square miles of land.

Saunders Island is geographically stunning, as well as rich with remarkable wildlife. The island is made up of three peninsulas that are joined by narrow necks of land. The three uplands towner over the necks, with the tallest, Mount Richards, being 1,500ft above the waves below. The views from the headlands are astonishing.

Saunders Island has been designated an Important Bird Area (or IBA) thanks to the large numbers of breeding species that make their homes here. The beaches and cliffs are home to four species of penguin with thousands of Gentoo, Rockhopper, Magellanic, King penguins - you can’t avoid hearing their raucous cries from all over the island! There also tend to be a few Macaroni Penguins and if you are lucky to see then you will have had a five penguin species day!

Other significant species to be found on Saunders include Falkland Steamer Duck, King Shag, Black-browed Albatross, the Striated Caracara (can be very inquisitive), Turkey Vulture, and a range of shorebirds, like the Magellanic Oystercatcher, to terrestrial birds from land birds from Dark-faced Ground Tyrants to the white-bridled finch. There are rats on the island so you do not tend to see the Blackish Cincloides or Tussacbird.

In the waters off the sandy shoreline, you can see the delightful Commerson’s dolphins - their black and white markings making them seem like miniature orcas - and even South American Sea Lions. Visiting Elephant Point will bring you face-to-face with the small colony of elephant seals that live here and gave their name to the beach. At the right time of year, if you are lucky, you might find southern right whales in the sheltered bays here feeding and resting before moving on.

Snow Hill Hut

Snow Hill Island is very well named! This large island is 21 miles long and over 7 miles wide and is almost completely covered in snow all year round.

It was first discovered by a British expedition in 1843 and named “Snow Hill” because it wasn’t clear at first if it was connected to its neighbor, Seymour Island. Subsequent surveys by a Swedish Expedition in 1901 found that it was, indeed, a separate outcrop, and “Island” was added to its name. The high ground on Snow Hill Island rises to approximately 560ft above sea level.

Snow Hill is important geologically. There have been many marine fossils found in its rocks, and huge dikes of had-wearing basalt rock have withstood erosion to become important and striking features.

The 1901 Swedish expedition spent three winters on Snow Hill Island, using it as a base to explore the wider area. They built a wooden hut in 1902 which still stands and is now a designated Historic Monument.

Snow Hill Hut is a 20ft by 26ft wooden building that is preserved as a time capsule and consists of a central living room, a kitchen, and 3 double bunks. You can still see furniture, bedding, lamps, plates, food packages, and more everyday items that were simply left when the hut was abandoned. The contents of Snow Hill Hut were then preserved in remarkable condition by the Antarctic cold.

There is the very slight chance of encountering an Emperor Penguin on an ice floe here since there is the Emperor Penguin colony on the permanent ice just to the south of Snow Hill Island. The actual colony is very inaccessible and only a few cruise ships manage to reach the location in the early season with all the additional ice (and when the Emperor Penguins are completing their breeding cycle throughout the winter!). In most cases a helicopter is also required to get closer, then a trek across the ice.

Stonington Island

For such a tiny, rock island (it’s less than half a mile by a quarter of a mile), Stonington holds a lot of the human history of Antarctica. It’s found in Marguerite Bay off the west of Graham Land, and it is one of the most southerly historic sites on the peninsula.

It was home to not one, but two winter expeditions. In 1939, the US Antarctic Service chose it as the location to build what became known as East Base. The buildings and artifacts here are now protected as a monument. Visitors can enter the main hut to experience something of what it would have been like to spend the dark and frozen winters on Stonington.

Later in the 1940s, the British chose the same small island for the location of their “Base E”. Again, visitors can enter the main hut and also the generator shed. Like the American base, there are other ancillary buildings that can’t be entered due to their status as protected monuments. There are permanent shutters on the windows of Base E, so your guide should provide you with torches if you venture inside.

In a solemn reminder of the harshness of the continent, there is also a gravesite where two expedition members are buried in coffins covered by simple stone cairns.

Stonington Island supports a colony of over 130 pairs of Antarctic Shags, as well as nesting sites for skuas and terns. As well as the landing there is a good Zodiac cruise around the island with the head of the nearby glaciers coming down from the polar plateau and to look out for seals and Adelie Penguins on the ice floes.

Later in the season fur seals and Humpback Whales can turn up at this southerly destination.

Torgersen Island

Torgersen Island is a very small, circular island only 450yds across. It’s part of the Palmer Archipelago and is at the entrance to Arthur Harbour on the southwest coast of Anvers Island.

It’s a popular site for breeding seabirds and Adelie penguins, but this small rock has a much larger, and more depressing, importance.

Although the current colony size of 3,000 breeding pairs seems large, since 1974 the Adelie population has reduced by over 60% due to the impact of climate change on the sea ice and snowfall patterns. An Adelie colony that was based on the neighboring Litchfield Island has disappeared completely in this time. Archeological surveys showed that penguins had been nesting there for over 600 years continuously, with up to 15,000 pairs in residence at a time. By 2007 they had all gone.

The island is very close to the American Palmer Station and it is divided into a Visitor Zone and a Restricted Zone. The Visitor Zone is for general access, whilst the Restricted Zone serves as a control site for scientific research related to human impacts. The Restricted Zone should not be entered, except in an emergency to access the emergency cache located on slopes opposite the landing site. Use the cache only in a genuine emergency and notify Palmer Station if anything is used.

Your expert Antarctic guides will show you the walking routes to take that will minimize any impact to the Adelie colony on Torgersen Island, as well as outlining the concerns that Antarctic scientists have about the continuing impact of climate change on the region’s wildlife.

This is a timely reminder of the necessity for change in the way humans live and use fossil fuels if we are to preserve the unique species and landscapes of the Antarctic. At Polartours we are playing our part in this story by carbon offsetting every polar cruise package we sell.

Whalers Bay

A very popular destination, Whalers Bay is a small natural harbor on Deception Island, one of the South Shetland Islands. An active volcano, the crater forms a natural sheltered inlet that was historically used by sealers and then whalers from the 1820s. The geography makes it a perfect place for ships to shelter in rough weather, and Whaler’s Bay contains some of the most significant whaling artifacts and remains to be found in the whole of Antarctica.

As your ship sails through the narrow “break” in the volcanic caldera known as Neptune's Bellows, the wide, circular beach of Whaler’s Bay is found to the right. The beach runs uninterrupted for one and a quarter miles and was used as a runway in the 1950s and 1960s when the site was the main hub of British Antarctic air movements. The hangar that was built in 1960 can be visited at the northern end of the beach where you can also see a roller that was used to maintain the runway.

At the southern end of the beach are large, rusted oil tanks, and behind them are buildings from the period 1906 to 1931. There was a significant whaling industry here, with the sheltered and shallow beach making it an ideal place to land whale carcasses and process them.

While you explore all this remarkable human history, please remember that you are standing on an active volcano! The instruments you may see around the beach in the Whalers Bay area are seismic monitors, and the island is monitored for activity 24 hours a day. The last eruption was in 1969, and this was responsible for some of the mudflows and damage to the buildings and metal tanks that you see here. It creates a very eerie derelict industrial landscape, in Antarctica, even bleaker with the black volcanic cinder.

No penguins breed, but small numbers of Gentoo and Chinstrap Penguins turn up on the beach and they can be surprisingly inquisitive. Later in the season you might encounter fur seals who have hauled out to rest and watch the humans. Other birds to look out for include Cape Petrels, giant petrels, skuas, Antarctic terns, and Kelp Gulls, that take the chance to feed on the krill and other prey stunned in the hot waters.

Guests often take the polar plunge here with the warmer layer of water with the heat from the steaming volcanic sands. There is also the walk up to the viewpoint at Neptune's window.

Wordie House, Winter Island

Nestled onto the only flat part of Winter Island, Wordie House is a hut built in 1947. It was named by a British Antarctic expedition of the time after James Wordie, who was the chief scientist on Shackleton’s famous 1914 Antarctic exploration. Winter Island is less than 1,000 yards long and is one of the Argentine Islands off the coast of Graham Land.

Before it closed in 1954, the hut was used to take meteorological readings using instruments stored inside special screens, one of which still stands today. These readings were among the most important and longest set of weather data ever recorded about the Antarctic and helped scientists gain a greater understanding of the meteorology of the continent.

Wordie House was made a “Historic Site and Monument” in 1995 and has been looked after by the UK Antarctic Heritage Trust since 2009. There are almost 500 original artifacts still on the site, including original cans of coffee, records, pots and pans, plates, and many more £everyday” items. This makes Wordie House a true time capsule from the golden age of Antarctic exploration and scientific research. The hut is now fully weathertight, and work continues on preserving this unique station.

Close to Wordie House there used to be the British Faraday base, the place where researcher's discovered the expanding Ozone hole. When the base was going to close, rather than dismantling this important and historic base (and one of the best bars in Antarctica!), it was given to the Ukraine for one pound!

Visits to Winter Island and Wordie House are managed by the nearby Ukrainian station Vernadsky, and you may well be briefed by the Base Commander or other official before you board your boats for the landing. The visit to Wordie House is often in conjunction with a visit to the base, and the chance to have a vodka and the impressive wooden bar.

The short Zodiac cruise between the two locations passes through some interesting gullies and the chance to check out seals and penguins on small ice floes.

Uniquely for such a historic site, visitors are allowed to roam freely under the supervision of their expert Antarctic guides. They will answer all your questions about the history of the hut, as well as the artifacts that you can find here.

Visitors to Winter Island can also expect to see seabirds such as skuas and kelp gulls, as well as seals and penguins. Humpback Whales are often seen in the more open waters close to the anchorage.
