2022 Antarctica: South Georgia Island, Salisbury Plain (12/11/2022)

Sunday, December 11, 2022
Temperature -5oC/23oF.
Today started with a continental breakfast from 4:30-5:30. We were supposed to have a Zodiac cruise and landing, then return to the ship for brunch at 7:45.
South Georgia Island is part of the British Overseas Territory that includes the South Orkneys, the South Shetlands, South Sandwich Islands, and Graham Land on the Antarctic Peninsula. It was a commercial center for fur seal skins and elephant seal oil from 1786 to 1909. As the seal population neared zero, the whaling industry began 1904, ending in 1966.
Beginning to load the Zodiacs
The Zodiacs took 8-10 passengers, with an expedition
guide at the helm; it was the luck-of-the-draw as
to whether you had a knowledgeable and/or good driver
Lucas Glacier...
...then farther right is Grace Glacier whose shrinkage has provided more land for the
Aptenodytes patagonicus/King Penguins (those tiny white dots on the beach) to breed
We could already hear and smell the King penguin colony! Adults trumpet and chicks whistle, and everybody poops.
Oh! A fur seal who is actually bathing
as he rolls around in the water

Landing at Salisbury Plain, site of the second largest
King penguin colony on South Georgia Island (KSS)
In the world, the King penguin population is estimated to be 1.5-2 million pairs. On South Georgia Island, there are about 450,000 pairs, of which 75,000 pairs breed at Salisbury Plain.
A loving couple?
Arctocephalus gazella/Antarctic Fur Seals are territorial
and ferociously protect their kingdom if you come too close;

King penguin family; the chick in
the foreground is nearing the end
of losing his first downy feathers
Penguin feathers appeared to be just over one-inch
long, and the adult moult each year; the outer layer of
feathers are oiled and waterproof while the
inner layers are downy for insulation
We were to try to stay 5 m/16' from the wildlife,
but often they would approach us and in backing up,
you were in danger of trodding on another animal!

King penguin chicks cannot swim until their waterproof
layer of feathers grow out, so even though they are nearly 
as tall as their parents, they depend on them for food (KSS)

It takes 13 months for a King penguin chick to
be ready to go in the water and feed himself
With early and late breeders, the chicks born closer to
winter often do not survive, and evidence of that is everywhere

ready to fledge/become independent this year

these brown birds to be another species

The parent King penguin leaves to feed on fish in the sea,
then returns calling to his chick whose cry he recognizes,
then he will regurgitate his food to feed the chick (KSS)

The King penguin second from the right has a brood pouch
above his feet; this is where the egg is kept warm for 55 days
while resting on the tops of the feet; both parents share this duty

Tens of thousands of penguins!

A large gathering of King penguin chicks is called a
crèche, and in the winter they huddle togther for warmth

This adult looks fat because he is
preparing to moult when his new
feathers have fully grown in
While moulting, penguins cannot go in the water and must survive on their own fat.

By the time we completed this Zodiac excursion, we had to skip the planned excursion to Hercules Bay, and have lunch.
Next: Grytviken.
