This entry is part 1 of 1 in the series Bird Island
As I have mentioned before (and you can probably guess from the name) there are a few birds calling this place home!
There may not be a huge amount of diversity here but the species and sheer numbers of birds present are spectacular.
The island is quite large (4km long) but there isn’t a huge number of birds obvious on the ground; that’s because most prefer to nest under it, thanks to the high density of predatory birds above.
To live and work on this island has been my dream for years, but the real pulling factor for coming back to South Georgia wasn’t, believe it or not, the penguins …
Nope. It was the chance of working with Antarctic Fur Seals again. Well, that, and living in a Wandering Albatross colony.
Sadly, I won’t be here for the entire year, which means I won’t get to see the entire breeding cycle of the Wandering Albatross, since they can take 13 months from laying to fledging.
So, unlike most species which were here at the beginning of the breeding season when we arrived, the Wandering Albatross were finishing up. The fledglings were beginning to leave the island, having spent the entire winter on the nest alone, only being visited by their parents to be fed before they disappear back on another several thousand km foraging trip.
Not all birds lay on the same day obviously and thus it follows, just as obviously, that not all were the same age.
When they are approaching the right age, they actually weigh more than their parents and just before fledging, they regurgitate all the hard parts of there diet (squid beaks, fish bones and sometimes plastic) and head for sea.
Wandering albatross breed every other year so, despite the fact that last year’s birds were fledging, the new birds were also beginning to arrive, ready for the present breeding season.
Whilst the wandering albatross can be found over the meadows higher up on the island, the beaches are covered by fur seals (or “furries”).
Considering that a hundred years ago, these animals were hunted to economical extinction on the island, it’s mind-blowing to consider their numbers are now in the region of 4 million.
There aren’t many success stories like this that I can think of but seemingly Humpbacks and Southern Right Whales are on a similar path, based on the quantity of animals being seen from shore this year.
Unfortunately, food was less plentiful this winter and the seals are paying for it. From looking at the diets of the seals throughout the year, we can see how well they are eating and what prey items are available. After poor winters, breeding numbers are often low.
However, even in poor seasons, the beaches are absolutely covered in fur seals. From looking at the diets of those that have bred this year, we can see that the krill have returned and as a result, the pups are fat and doing well.
Nevertheless, I couldn’t write a blog from South Georgia without a penguin picture or two. One of the many great things about Bird Island is how accessible the wildlife is and with a Gentoo Penguin colony just a few hundred metres from base, it’s been easy to keep tabs on how they are doing.
A few weeks after arrival, the eggs were cracking and the gentoo siblings were emerging.
A little further away (but also a little more spectacular) is Big Mac, home to 80,000 Macaroni penguins. These are obligate reducers, meaning they lay two eggs but only one will hatch – and that’s what they are starting to do!
In other news, molliemawks (grey-headed and black-browed albatross) and Giant Petrels have fat chicks.
That’ll have to do for this weeks photo fix… Hope you enjoyed
Its been a long while since I wrote a blog but now that I am back settled in colder climes I think it’s about time that I update this website.
I am back in my favourite part of the world living on a small island 500m North West of South Georgia. It’s aptly named Bird Island since its home to hundreds of thousands of seabirds and penguins. So dense is the wildlife here that there is either a seabird or seal every 1.5m2.
As with all travel in the Southern Ocean, ‘Plan A’ very rarely comes to fruition. I set off from home via RAF flight to the Falklands where I had a couple days to explore the rich wildlife the islands have to offer. Having been to the Falklands several times now I am still amazed by what’s on show here. With it being located north of the subantarctic convergence the species found here are slightly different and there were great opportunities to see Southern Sea Lions, Rockhopper Penguins and Imperial Cormorants.
The Falklands will literally blow you away with wind and rain almost as predictable as beautiful wildlife!
Bull Seal Lions are formidable animals weighing 350kg
I then headed south on board the Naval patrol ship, HMS Clyde. My next destination was Bird Island. 3 days sailing away. As we made our way South on the unusually flat calm seas we were treated to views of fin whales, right whale dolphins, Peale’s dolphins and Humpback whales as well as lots of seabirds.
As I woke up on the 3rdmorning, just north of Shag Rocks, ready for my 5am ice watch on the bridge, we were greeted by a 2 by 3 mile iceberg which had a couple of smaller bergs which had broken off. Fortulately the captain was up on the bridge and suggested we position the ship so that when the sun rises it comes up directly behind the ice berg. And this was carried out to perfection!
Unfortunately the next step of the plan worked out less perfectly as we approached Bird Island which is very exposed to the prevailing winds and swell. The decision was made to not even attempt landing meaning we would reposition to my old home at King Edward Point and wait patiently for a different lift.
There are definitely worst places to be stationed on standby. Read my next blog here
As much as it kills me to have left my work with the British Antarctic Survey, the new job has some pretty amazing perks. Working at King Edward Point allowed me to see a small part of South Georgia over a long period of time working immersed within incredible wildlife. However, life on board National Geographic Explorer has 5 star food every night, a masseuse and most importantly, access to much much more of the island than we were able to visit from base.
One of my favourite new landings to visit this year is Gold Harbour. Not the largest king penguin colony on South Georgia but still spectacular.
One of the many things that make this site stunning is the Bertrab Glacier, which hangs over the colony.
During spring the beaches are covered by harems of Elephant seals which push the colony back into the tussock.
The breeding season is a difficult time for these giants. Beachmasters will spend months on end starving on land, battling to defend their harems from competitors. During this time, the battles can be brutal and so moments of rest and recovery must be taken at every opportunity.
Not all the fights end in blood and gore; youngsters are always practising because they know that at some point it will be their turn to fight for real.
As the elephant seals head out to sea for a much needed foraging trip the beach opens up, allowing other wildlife some space to thrive.
Wherever there are penguins and seal colonies, predators and scavengers are never too far away
Although not in the same abundance, elephant seals can still be found here late in the season since they return to the South Georgia coast in order to moult. This process takes roughly a month. Several animals will lie in the same location for most of this process and the combination of their weight and excrement kills everything beneath them, leaving foul smelling wallows throughout the coastline.
If the wildlife doesn’t quite do it for you, then you can keep your eyes above the seals and penguins and it still ain’t half bad.
Despite the 4 a.m. mornings there is very little that can spoil an experience like this. However, we did find one thing that did just this on our final landing of the season. A young Antarctic Fur Seal with fishing material wrapped around its neck.
Despite South Georgia’s isolated location, there is no escape from marine pollution. Ghost fishing and marine waste are a real problem here. During my time on South Georgia we freed, any number of animals entangled within fishing or packaging waste. And on a landing at King Haakon Bay, we even managed to retrieve a washed-up fridge from the beach, as well as numerous bottles and bags.
If you think about how little activity and fishing there is in sub antarctic waters in comparison to other areas further north then the impacts and effects this will be having is hard to fathom. Over 100,000 marine animals are harmed through pollution such as this every year.
Not to end on a negative note, here are a few time lapses from a day at Gold Harbour
It’s been a while but I thought it was about time that I wrote a blog about a typical day as a Naturalist on board the National Geographic Explorer. And what better location to do so than from Salibury Plain. The second largest king penguin colony on the island, Salisbury Plain lies within the Bay Of Isles towards the North of South Georgia.
After a blustery night anchored in the Bay of Isles, guests awoke expecting poor conditions but were pleasantly surprised to see flat seas and a fresh coat of snow covering the bay. Just five days previously, when we were last in the bay, there was barely any snow on the near mountains.
Its been a hard year for these King Penguin chicks, after the eggs were laid a year ago they have been stuck on this beach through the harsh South Georgia winter. Some of the chicks will have gone months between feeds shrinking up to 50% in weight during these periods.
The landing did not disappoint, a natural path through the colony allowed guests to get their best views of the “Oakum Boys” yet. Despite the cold temperatures, the light was stunning and guests used every second on shore to get their shots.
The cold was obviously too much for this penguin who couldn’t stop sneezing!
By this stage of the breeding season, the weakest chicks will have perished, so those remaining all looked in good health. After more than a year of development these chicks will soon loose this downy coat in favour of their waterproof juvenile coat.
After a long but spectacular morning on the colony we headed back to the ship for hot drinks and tasty food, a luxury which the British Antarctic Survey never provided!
The island is home to millions of birds including ten of thousands of Black Browed Albatross which thrive in these windy conditions.
NOT FOR THE FAINT-HEARTED.

Although not the prettiest birds to grace the planet, if you ever get the chance to see giant petrels in the wild, they will command your respect like few others. There is nothing quite like watching the coming together of hundreds of these majestic giants at a recently deceased corpse.
With piranha-like efficiency, giant petrels can tear hundreds of kilograms of flesh from an elephant seal skeleton in hours, with powerful tube-nosed bills strong enough to crack open a seal skull. Plunging deep into the carcass, the heads and necks of these usually exquisitely preened birds quickly become coated with bright red blood and gore.
Equally as striking is the intraspecific competition for the optimal place at the carcass. The birds posture with wings spread and tails fanned, moving their heads from side to side whilst emitting their best war songs – unforgettable primitive guttural cries – to deter challengers.
If the deterrent is unsuccessful, the birds clash chest to chest, locking bills and slapping wings until one challenger concedes. It’s a spectacular display of carnage from this ultimate scavenger.
Because the males are larger than the females, gatherings such as this are usually between males whilst females tend to forage at sea where competition is less harsh.
I was recently approached by Will Harper-Penrose from Woodmansterne Primary School and Children’s Centre via the wonderful medium of Twitter. His year two pupils were learning about the Antarctic and exploration, and he got in touch to ask about the possibilities of doing a Q&A Skype session.
Unfortunately, South Georgia’s internet connection was not up to a Skype video so, on hearing that, Will came up with a much more imaginative way to ask the questions. Being a music teacher, he composed a song for his pupils to sing, asking questions like ‘Have you seen a penguin sliding on its belly?’ and ‘What do you eat in Antarctica?’
As you can see for yourself, the video, song and dance are awesome and put a smile on everyone’s face on base. Completely aware that this amazing video would outshine any video of mine, I used my surroundings on the island to assist me, featuring penguins, seals, icebergs and boating, here is a compilation of some of my footage from a year on South Georgia.
I hope that this will entertain the kids and hopefully inspire one or two to become polar scientists
Absolutely devastated to leave South Georgia after an incredible and life changing year. If anyone gets the chance to visit I would 150% recommend it! It has everything, landscape, wildlife, glaciers and very occasionally the sun also.
It was an absolute pleasure spending the year with this team. One final BBQ in the snow as well as a final champagne toast and it was time to set sail on board the Shackleton.
As to be expected the scenery on the way out was still magnificent and a few species of wildlife made the effort to come and see us off.
On our way North we passed several, huge icebergs which were obviously floating north from the continent
Once within flying range of the Falklands a Hurricane made a flyby whilst carrying out a training exercise allowing great views for photographs
Technically I have left South Georgia but I am aware that I haven’t posted many blogs over the past few very busy weeks. So I will catch you up on my activities with a few blogs! The beginning of spring brings a series of fresh faced new British Antarctic Survey recruits eager to takeover from the old guard and ready to learn their new job.
First on the long list of Kierans (the new me) new responsibilities was the Giant Petrels. Fortunate for us, these prehistoric birds have the a habit of nesting in areas of especially spectacular backdrops!
Where ever there are Giant Petrels there are glaciers not too far away so its often harder to take pictures without glaciers in the background.
There are colonies of Northern Petrels at Maiviken, Zenker Ridge and the Greene which nest approximately six weeks ahead of the Southerns which nest at Harpon and on the Greene.
The latest trip was to check up on the Southerns which should have all laid by now. The Northerns, are starting to lay and will have chicks by now.
Both sexes are very similar in appearance. However females tend to be smaller in size.
Last month I made the short voyage up the coast of South Georgia to The Bay Of Isles and Prion Island to check up on the Wandering Albatross. These are the world’s largest seabird and they nest in numerous colonies around the South Georgia coastline.
A few years back when I saw my first ever albatross on The Galapagos, I put ‘seeing wanderers on the nest’ top of my bucket list.
I didn’t think for a second that I would be able to cross it off so soon. To be allowed to get up close and personal with such incredible birds was a privilege and a pleasure, but now I need something else to take top spot …. maybe diving with leopard seals!
The trip was a success but with the weather window being very narrow, there was much concern that we may not manage to get the work done. However, after a dawn wake-up, we managed to get landed.
Of the birds present, when I last monitored Prion back in April, 100% had successfully made it through the winter and all should hopefully be fledging before the end of the year.
The island is also home to a number of other species which have been able to thrive without the presence of rats. Two colonies of Gentoo penguins were all sitting on freshly laid eggs, Giant Petrels were courting and laying, Pipit chicks were calling from nests all over the island, Light Mantled Albatross were sitting on nest bowls and White Chin Petrels were singing from their underground burrows. Also, the first few male Fur Seals were taking up residence on the beach.
