Wildlife in Antarctica

A series of short stories by Mark Stratton

Antarctica is an IMAX experience of biodiversity on an epic scale, where the battle for survival in mighty seas and surreally beautiful glacial landscapes can be visceral, comical, and most certainly for all who experience it, life changing. I recently boarded Polar LatitudesIsland Sky, an elegant and small ice-strengthened vessel for my fourth expedition to the 7th continent. Nineteen days at sea on a 3747 nautical-mile odyssey through the Falkland Islands, South Georgia, and Antarctica. This is my wildlife journey told through short stories.

Why do seabirds follow cruise vessels?

It wasn’t long after slipping out the Beagle Channel from Ushuaia into the Southern Ocean before an entourage of seabirds began following our vessel. It often begins with black-browed albatrosses and the region’s persistent scavenger, giant petrels. During onboard seabird surveys, we would count fifteen species swirling around Island Sky, rising and falling effortlessly on the ocean currents. Tiny Wilson’s storm petrels dance above the waves while flocks of dappled cape petrels flutter delicately like a light snow flurry. But why exactly do so many seabirds follow the vessels?

“It’s not known for sure,” says Lisa Lapointe, our onboard naturalist. “It could be seabirds are attracted by the smell of dimethyl sulphide (DMS), which is present in phytoplankton and released into the air when our ship passes over it. This brings them to food sources of krill,” she said. “Or perhaps, they’re just curious about our presence”.

How many penguin species will I see?      

Penguins are what travellers to the Antarctic region crave. Depending on who you ask, and even penguinologists are divided, there are globally sixteen to eighteen species. With certainty you’re sure to meet plucky gentoo, chinstrap, and macaroni, in Antarctica, and even further south in latitude, you’ll meet Adelie, their all-black heads faintly reminiscent of a medieval executioner. Our voyage offered extra possibilities to boost that tally. Our Falkland stopover at Gypsy Point, revealed burrowing magellanics, while southern rockhoppers, which look quaintly mad with yellow-and-black mohawks, bounce around the clifftops. But it’s the king penguins most want to see. There are Falklands colonies, but two-days further sail to South Georgia presented one of the great wildlife spectacles on earth. in control of its ecological destiny, left me humbled.

What’s it like to see a million penguins?

Speeding into St Andrews Bay in eastern South Georgia Island on an inflatable zodiac, first it’s the acrid pong of guano that assailed my senses before, what another guest described as hearing ‘an orchestra of kazoos’, the volume of the colony became deafening. The sound of one million king penguins – tall and elegant with golden patches along their beaks and heads. We splashlanded onto the gravel shoreline where for kilometres along the cold ocean front the kings either entered the sea to fish or were returning, bellies full of krill to feed their squeaking chicks who loiter in brown downy coats.  The beach wriggled with fur seal pups during my short walk to a tussoc grass mound where the full majesty of the colony was revealed. Hundreds of thousands of kings. The collective power of feeling nature is so in control of its ecological destiny, left me humbled.
