It has been about two months since I have updated this blog
so it is time to catch up!
The reason for the big delay between posts has been
how busy the work has been in this time. In early April we had Last Call when
the RRS Ernest Shackleton dropped off our last bits of cargo and food for the 7
month winter ahead whilst also taking Al and Siân back home, it was amazing to
work with you both and you are greatly missed on the island! Of course, not
only did we have to prepare for the Shack but I also had to prepare for taking
on the albatross ZFA role as well.
As previously mentioned Lucy is staying on
here for a second winter which means going on a well-earned holiday for a time
first, so Lucy has trained me in her role to cover the workload for April and
May.... but there will be more on that in the next blog!
So what has happened in the past two months? Well the main
change has been winter has come (but thankfully no white-walkers are yet to terrorize our shores)!

The changing seasons has made a big difference to the
species we see around as the northern geeps have now all fledged and the
macaroni penguins have all left the island until they come back in October. The
southern giant petrels are about to fledge as well whilst the mollies will also
be gone by the end of May.

But that doesn’t mean we are deserted for the winter, far
from it! In this season numbers of other birds greatly increases. Pipits and
pintails are pushed out of the islands interior, where ponds freeze and tussock
gets covered in snow, down into the bays where they can forage in the shallows
or strand line.

Pintails are actually one of two species, alongside
sheathbills, that I will be counting twice a month from May to August. But when
you get over 200 of them in one go it is worth counting them a few weeks early!
 |
| 211 pintails in one location! |
Gulls and shags can still be seen around the coast in good
numbers as well but the greatest difference is in the smaller petrels. Cape
petrels have made their way in to our bays in large numbers to feed on small
critters in the seaweed and we are occasionally treated to a glimpse of
storm-petrels as well!
 |
| Cape petrels rivaling the pintails for numbers, 170 is the biggest count in one location so far! |

Not only has the bird world changed but so has the mammal
world. Winter marks the arrival of leopard seals. Whilst we had an
unseasonal visitor back in February it is May to October when these massive creatures
normally come ashore. That being said, they have arrived early and we have
already had over 15 sightings in April alone!

But whilst all the wildlife has been great to watch in
transition when talking about the arrival of winter on a sub-Antarctic island there
is only one element of change that gets the prize for most dramatic – snow/ice!

Not long after Last Call in early April we got the first
flurries of snow. This was followed by a day when the wind gusts topped 50
knots and the base was literally shaking around us (it’s built to withstand
that though, so it’s normal in bad weather!). Waking up after a night when the
50 knot winds were dying down was an interesting sight for us all..... ice! And
lots of it!
 |
| Ice filling the bay and altering the coastline |
Not only had ice been blown in to the bay outside base but
it had arrived in such large quantities that it covered the shoreline quite
spectacularly and pretty much drowned our jetty from view. There was so much in
fact that much of it is still here two weeks later.
 |

After all the ice came in we had regular snow falls which
has now left the island covered in snow ranging from 2 inches thick to waist
deep depending on the topography of where we are. This had made traversing the island to complete our ongoing
fieldwork more of a challenge, chains on our boots help combat the slippery
ice, but when walking across tussock or part-frozen bogs it is near impossible
to see where the big gaps or weak spots are. This has resulted in numerous
falls for us all and occasional wet feet as we go through the ice layer up to
our knees, or even our waists on occasion!
But despite the difficulties it poses having the whole
island covered in snow is absolutely breathtaking and at least makes going
downhill much more fun and a lot quicker!
