Hello again from Cape Shirreff. Here's the weekly update (you may also be
receiving the
SitRep which is a weekly report we have to send to the government
in DC so they know what is going on and that their money is going to good use.
You may or may not be interested in reading them since they're a little on
the dry side.) Today I got home from the field early. It's only 4:30pm
and I have the whole house to myself - ahh, solitude. Actually, while the 4 of
us are somewhat on top of each other in our living quarters, I spend the
bulk of my day out in the field wandering alone amongst the squawking
penguins. Mike and I spent most of yesterday gathering data on adult
penguin weights at laying, and getting egg measurements. This involved
first lifting up hundreds of penguin butts to find birds who had only laid their
first egg, stealing their egg to weigh and measure it and then sneaking the
egg back on the nest and successively catching each adult to toss them in a
stuff sack and weigh them. The whole process is pretty quick and while a
few birds freak out, most of them seem to get over it quickly and get right
back on their nest. It is exhausting catching and being thrashed by 50+
penguins (we each did 50 birds). Mike got some good video footage of me
getting brutally flippered and bitten by one particularly uncooperative
bird, granted he only weighed 4 kg, but he was fierce nonetheless. Never
underestimate the power of a small flightless bird. We have also started
monitoring our skua nests to get lay dates. I check 10 skua territories.
It's great work because they choose the highest, most inhospitable points
on the island to nest on, so I have to scramble up snow and scree slopes in
the howling wind (the weather has taken a turn for the worse with very strong
winds from the east hammering us) and search for scrapes (skua nests aren't
much, just a divet scratched in the soil.) While skuas are normally pretty
fierce, when they are on eggs, they are very docile. They will screech a
little and call in their mate, but you can reach under them and take their
egg without getting your eyes gouged out. Apparently this isn't the case
when their chicks hatch and we have to band and measure them. They are
strong birds and can brutalize you, so that's a 2 person job.
We had a vagrant king penguin wash onto the island 2 days ago. Their
range is much farther north than Livingston Island and it is very rare to
see them down here. He seems a bit confused, but he did find the chinstrap
colonies. Sadly, he's twice the size of all the other penguins and just
doesn't quite fit in here. While Mike and I were searching for the king
penguin we got to observe a mama fur seal give birth. That was amazing to
see. The beaches are literally covered with fur seal pups and the cries of
mothers and their pups can be heard all night long. I'll get to help the
seal biologists when they start to do pup captures next week. Should be
exciting.
In response to a couple of questions... how did I end up down here and
what exactly am I doing... I actually found out about this research
position on the internet and applied for it. My boss Wayne
hired me over the phone as I was headed out in the field on a Yukon hiking
course. This research position is perfect for me because it is short term
(4 mo.) and I was looking for something to provide some variety and
intellectual stimulation as a break from NOLS work - which I'll continue
when I return to the states. Now one may argue the true quality of
intellectual stimulation that I am getting as I slog through penguin dung,
but it's nice to be immersed in a scientific community again. The work we
are doing is part of a long term monitoring project required by the
Antarctic Marine Living Resource conservation treaty. They basically need
to know population sizes, reproductive success, etc. of larger marine
predators and seabirds. NOAA also contracts a boat to do transects to
measure krill density and other oceanographic variables. Most of the
penguin and skua work we do is gathering basic ecological data. Wayne has
been studying penguins for over 24 years, so he's somewhat of an expert in
the field. He'll be joining us in January for our final 2 months.
Well...I'm starting to hit my e-mail size limit, so I'll sign off. I
also have to go shovel some snow. We're worried that our fresh water
supply might run out if we don't get some precipitation soon. We have 10 50gallon
barrels full of water/ice, but the snow is melting fast, so I need to fill
up some more barrels.
Lots of love, Iris
