This entry is part 1 of 1 in the series Bird Island
Before coming South, whenever someone mentioned the Falklands, I would think of barren and windy islands with not much to offer. However, I was pleasantly surprised with the reality. Many of the guests on board the ship have the same mentality as I once did, seeing the Falklands simply as a convenience stop to stretch their legs before we get down to South Georgia and Antarctica. They most definitely are not anticipating the beauty of sites such as West Point Island and the densities of tame wildlife that these islands offer.
The Falklands are home to 60-70% of the world’s breeding black-browed albatross and host the largest albatross colony in the world at Steeple Jason. Seeing thousands of these birds proudly perched on their nest structures for as far as the eye can see is a breathtaking experience.
Many of the colonies are also home to thousands of rockhopper penguins early in the season and watching the entertaining relationships between these species is endless fun. The sounds that accompany these interspecific relations are also entertaining.
Both the rockhoppers and the black browed albatross tend to pick the most exposed areas of the islands to breed. The albatross are dependent on the wind in order to aid their takeoffs and the penguins use the exposed coasts in order to deter predators.
The islands are also home to magellanic, king and gentoo penguins and if you’re lucky you may also see macaronis hiding within the rockhoppers.
There is also some beautiful, if a little flat, hiking to be had over these islands and you’re never too far away from geese, raptors and songbirds (especially on the rat free islands).
And when you get onto the sea the wildlife doesn’t stop. There’s a healthy population of steamer ducks patrolling the coastline and both Peale’s and Commerson’s dolphins are often around and keen to play.
One final albatross picture, because they are awesome
Few images from St Andrews Bay, South Georgia
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
Next to tick off the bucket list, the world’s top ocean predator – the killer whales. Having never seen these before, I travelled to Antarctica with very high expectations, knowing estimates of these animals in Antarctic waters to be somewhere in the region of 70-80,000.
On just our second day in Antarctic waters, we kept the schedule free and were instructed to get outside and look for big black and white animals. Within a few hours in the Weddell Sea, we were surrounded by several groups of Type B killer whales.
We were lucky to have killer whale scientists on board the ship and within a few minutes of the sighting, they were launching the Zodiac in order to get closer to these animals and collect their data.
The scientists, from the NOAA, were using drones to fly above the animals and take pictures, which give them accurate information about the size and health of the whales. This new technique of observation also allows them to see what the whales are getting up to beneath the water, observe new behaviours and also make more accurate counts of pods.
As you can see, the killer whales in the pictures have very brown colouring where stereotypical killer whales would be white. This is a result of the cold water temperature – the brown is actually diatoms (a type of single cell algae) living on the surface of the whales. Normally, killer whales would have a good blood flow to the skin, which would prevent this diatomaceous growth. However in cold waters, this would involve the loss of too much energy.
If you look closely at the images, you can see round circular scarring on the whales, these are from cookie cutter sharks, which are only found in the tropics, a bit bewildering considering these killer whales are seen in Antarctic waters all year round.
Also, it was strange that the same individuals, photographed on different days, often had high diatom growth followed by clean skin. The NOAA team previously put tags on these whales which showed that they make very rapid journeys to the tropics to get manicures before swimming all the way back south!
Next up were the Type A killer whales, which are much more like the killer whales seen in the northern hemisphere. These are larger and tend to be more black and white than the Bs and they feed on Minke whales and elephant seals.
Using a combination of the saddle patches, markings and fin shape it is possible to identify individuals using photos. We were lucky to see the same group of Type A killer whales near Ciervo Cove on both expeditions, as confirmed by photos.
There are two types of B killer whales. ‘Little’ Bs, which tend to dive deep and feed predominantly on fish, supplemented by the odd penguin! And ‘big’ Bs, which opt for washing seals (especially Weddells) off the ice to feed. Having seen the little Bs several times already, we pushed further into the Weddell sea into the thicker ice and, as we hoped for, we found a group of big Bs, giving us the “full house” for the area we had been.
Since conditions were calm, the ever eager scientists launched the Ribs and returned with some alarming images of the whales. The whales were not in particularly good health, with much of the skeletal features of the animals visible in the pictures. Possibly, this was a result of lower prey scarcity, with very few Weddell seals observed on the ice. However, at this stage the scientists could only hypothesise.
We also had a team from CBS on board who did a piece on these encounters, which you can see by following this link below…
Fortunately, the trip did not end on this low since sightings continued wherever we went. My season culminated with one of my favourite nature experiences ever, as a group of 40 little B’s passed straight across the bow of the vessel in the crystal clear Antarctic waters.

Another blog from my latest amazing trip to Antarctica, focussing on Humpback whales this time. You’ll be glad to know that there is less blood than in the previous post.
Having lived for a year on South Georgia, immersed in the depressing history of Antarctic whaling and the impact of humans on Baleen whales, it was amazing to sail through Antarctic waters and see first-hand how the whales are bouncing back. Sightings of baleen whales were frequent with the most common being humpbacks: these majestic 36 tonne beasts were almost ubiquitous throughout, it was an absolute pleasure.
Almost without fail, by the time breakfast was served on board National Geographic Explorer, there had been a blow, or a sighting of the distinctive hump, or flukes of these animals.
Possibly the best experience of my time on board came as the sun was setting on an already eventful day of killer whales and penguins. Stupidly thinking the excitement was over for the day, I retreated to my room in order to download a few photos, when the call of ‘feeding Humpbacks’ came out over the tannoy.
As a kid, I read about bubble net feeding whales and had seen footage of it numerous times on David Attenborough documentaries. For those others who have seen this footage, you will understand why seeing this activity has been on my bucket list for years. However, travelling to Antarctica, I had no expectations of ticking this off the list, since it was my understanding that such behaviour had only been observed in Alaska!
Bubble net feeding is obviously a foraging method where the humpbacks blow clouds of bubbles around their prey at the surface. This traps the prey between the bubbles and the surface allowing the whales to swim up with their mouths open and take huge mouthfuls of prey.
The video bwlow shows one of these events happening and you can see the bubbles at the surface before the humpbacks lunge through open-mouthed
Humpback whales that spend summers in the Antarctic, exploiting the rich cold waters, migrate north to spend the winters in the tropics around Costa Rica. Here, there is an overlap with the Northern Humpbacks that spend their summers in Alaska and migrate south also to Central American tropics. The hypothesis is that these Northern whales, having learnt and practiced the behaviour in Alaska, migrated south to Central America before continuing through to Antarctica.
As a result, you now have whales practicing bubble net feeding in Antarctic waters. The humpbacks have uniquely marked flukes which allow them to be identified.
Hopefully, the individuals we photographed in Antarctica will have been observed previously in the world and we will get a better understanding of how this behaviour has spread.
And when you get bored of the whales (as if!) the sunset and the ice aren’t too bad substitutes!
NOT FOR THE FAINT-HEARTED.

THIS POST IF YOU ARE AT ALL SQUEAMISH.
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.
