Wildlife and travel photography and blog
Something that surprised me about my recent visit to the Antarctic Peninsula was that the ice was equally as impressive as the Killer Whales, Leopard Seals and the Humpbacks.
Nothing can prepare you for the different shades of blue captured within these floating structures and the size of the slabs is simply staggering!
Fortunately conditions allowed us to make it south past the Antarctic circle!
And if the Ice isn’t enough the landscape and mountains ain’t half bad either!
Its been a while since I posted pictures of my penguin friends so here are a few of my favourites from the Peninsula where I was finally able to see the Holy Grail of Penguin species; The Emperor Penguin. As well as all three species of brush tail, magellanic and rockhopper.

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!
Just a quick blog to say that the wildlife is slowly but surely returning to the South Georgian shores. The first few male Elephant Seals are making themselves back at home on the beaches, awaiting the return of the females. Hopefully, we should have the first females very soon, followed by the first pups and that should kick off the big fights between males for harems!
Along with the Elephant Seals have come increased numbers of Antarctic Fur Seals. Although breeding won’t start for these guys for a few months, it’s great to see them again and see them looking so healthy.
Antarctic Terns are increasing every day with a roost beside base reaching numbers of 150+ in the last few days. Birds can constantly be heard courting and seen displaying.
Our wintering residents are still here and I imagine will stick around in order to take advantage of the increased abundance of food! A peak of six leopard seals in a day vied for highlight of the month.
It’s not long now before the Gentoos will stop roosting close to the beaches and push on up to prospect their breeding colony for a year. With such a poor season observed last year, here’s hoping for better luck this time.
Giant Petrels are also increasing in numbers with the first Northern Giant Petrel observed on a nest already. Other seabirds are also increasing in the bay with more and more cape petrels close to base and also the first returning white chins. Hopefully, we should be seeing our first skuas in the next few days.
Male fur seals are already beginning to act territorially, meaning that I need to keep alert whilst patrolling the beaches.
It’s great to see these southern giants back around base, dwarfing the comparatively tiny fur seals on the beaches. They use the proboscis on their noses to project their calls, meaning on a still night, you are able to hear their roars from miles away.
Despite all this incredible fauna, probably the most exciting event in the last few weeks has been the return of bird song to the islands with South Georgia Pipits making themselves heard throughout the coastal areas.
South Georgia is absolutely incredible for rich and diverse wildlife, this is something we all know. What makes it that little bit more special than other places of this nature is the breathtaking scenery all around you wherever you go. With wildlife sightings currently at their lowest around base, I took a bit of time to photograph the landscapes.
Almost as spectacular as the landscape are the skies now that the days are getting lighter again: sunset and sunrise are falling perfectly in time with the beginning and end of work. We have also been witness to some amazing lenticular cloud formations in recent weeks.
Even with wildlife sightings down around base, I am still making the weekly trips to Maiviken to see the few lingering Antarctic Fur Seals. Its very rare that I make the commute and don’t get my camera out, even if only my phone (like the two below). I must have a thousand pictures of my route by now, but it’s not one I ever want to forget!
Our numbers have recently dropped with the loss of our lead boatman, who has headed back to the equally as spectacular Essex. His loss means that there is a much greater demand for the rest of us to take out the boats.
An out of character spell of calm weather has allowed me to rack up some hours of training in recent weeks on board the Jet boats. I have been training at night time navigation – during the day! Our boating officer, Russ, used a very high tech training methodology of putting cardboard on all the windows and making me navigate only using the GPS equipment. When I eventually stepped outside, the day and the view was pretty stunning (see above).
We have also had lots of time training with our Fisheries Patrol vessel, practicing ‘at sea transfers’.
Finally, myself and another team member, took the short commute across to Grytviken, for a night away from base. The weather was too good to stay indoors so we headed out with a flask of mulled wine and watched the almost full moon rise over Mount Duse and the derelict remains of Grytviken whaling station.
After a bitterly cold night, we were woken by a nosy neighbour at the front door, trying to get in to steal our warmth. A snowy sheathbill was wading through the snow in order to check if we had left any scraps. Unfortunately, we disappointed!
I’m often asked how frequently we get let off South Georgia for holidays and to see family. The answer is never!
For an entire year, I am restricted to the island.
But we do get much more freedom than other Antarctic bases and have a very generous travel limit. And we do get ‘holidays’ – kind of – where we get to visit neighbouring peninsulas for a short period with the help of boating support.
After a hard and very long summer, I took a few days off to visit St Andrews Bay. This is somewhere I have always wanted to visit, since watching David Attenborough documentaries as a kid.
St Andrews Bay is a stretch of land lying at the foot of Mount Skittle on the Barff Peninsula. It stretches 3km from the mountain ranges at each end and 2km between the ocean and the glaciers located at either side.
More spectacular than the bay itself are its residents. St Andrews Bay is home to the largest breeding colony of King Penguins worldwide. Depending on who you talk to, the numbers of penguins residing here are between 400,000 and 600,000. And having visited the colony, I can now understand why there is such ambiguity.
Literally everywhere you look, there are King Penguins. Along the beaches, there is a constant conveyor belt of birds as adults either return to land to feed their chicks or head to sea to stock up on baby food.
We were incredibly lucky to visit the colony at this time of year. Not only was it covered with a thick layer of snow, but also, amongst the adults, were chicks of all different sizes. Surprisingly, there were even a small number of adults still incubating eggs.
I wish St Andrews was on our doorstep but unfortunately not. In fact, in order to reach this spectacular phenomenom, we had to walk 20km across knee deep mountainous terrain in snow shoes. Upon arrival at our St Andrews Bay hut, myself and Robbie, exhausted from walking, ingested a kilogram of chocolate in seconds, which some philanthropist had kindly left for us in the hut.
Was it worth all the effort and exhaustion …? Well, you decide for yourself. As the saying goes, a picture paints a thousand words, so the rest of this post is silent …
