Time flies when you’re having fun or when you are in the accelerated time zone of Bird Island



I realise that February has come and gone without a single post on the blog. I haven’t really got an excuse for that, I thought that nothing much had happened. However when I started thinking about it I came up with a fair list of stuff. With these things the longer you put them off the more monumental the task becomes, but as it is a rainy Saturday morning I thought it was about time I got something written. 

Towards the start of the month Jen showed me the final task that I hadn’t yet done, diet sampling. Every two weeks for around 3 months I have to take diet samples from 5 Black-browed albatross chicks and 5 Grey-headed albatross chicks. This is a very smelly job and you tend to end up very dirty. All the other base members know when you’ve been out sampling as the boot room ends up stinking. We definitely aren’t the only culprits for stinks in the boot room, seals and penguins have their own aromas. 

Once the samples are collected Jen and I have to sort through them and estimate the percentages of types of food in the samples. Some parts including squid beaks, fish otoliths (tiny round bones from fish ears), and krill are retained for me to attempt to identify in the winter. 

I’ve found it quite enjoyable doing some lab work, as it’s been a pretty long time since I’ve been in a lab! It makes a change from being out in the field every day, and it’s always good to learn some new skills. 

February has been a month of changes.  Since arriving on the island in November we had seen no sign of outside life, this month we have had two ship calls from the James Clark Ross. A ship call is a day of great excitement! The first one called in to collect Jaume (seal biologist) who had been on the island for four months. It also brought us a sack of potatoes and some eggs (a source of great excitement) and post! I received a parcel from one of my best friends Zara, which I really appreciated. I’d say post day is much better than Christmas at home, as no matter what it is, it’s great to hear from the outside world and to know people haven’t forgotten about the few of us living on this little rock in the middle of no-where. 
Jon's leg after the seal incident

The ship’s doctor came ashore to take a look at Jon’s leg which had been subjected to an unfortunate run in with a male Antarctic fur seal. We’d done our best to patch him up by administering some local anaesthetic then giving it a good clean out with a toothbrush and a lot of disinfectant. With bites, especially seal bites, you wouldn’t normally sew them up because of the amount of bacteria in the wounds. However in this case as it was a fairly big gash and just below the knee, the doctor decided it needed stitching. We had only been practicing our stitching a few days previously so the doctor let a couple of base members have a go including Jon himself!

Just 10 days later it was another ship day! This time we lost Jerry who had been having some tooth issues and so has been sent back to the Falklands to see the dentist, he should be back in about 2 and a half weeks. From 9 original base members we were down to 7, but Iain, another seal biologist arrived to help out Hannah and Jon, so we were back to 8. Iain has a lot of experience of Bird Island as he wintered here some years ago when he was doing the same job as I’m doing, and he has been back on and off over the years.
The ship also brought us our first load of “freshies”- including lettuce, peppers, aubergine, bananas, oranges, grapes, avocados...... I won’t list everything but we were all thrilled after having no fresh veg for the last 3 months. It’s hard to imagine with the availability of whatever fruit or veg you could wish for in the UK, just how happy a few lettuces came make you. We also got four bags of post! I got a parcel from my grandparents and two parcels from Luke. I was very pleased with the high percentage of chocolate the parcels contained as well as photographs from home, and new music and films.

Last month it was the Gentoo chick weighing and census, this month it was the Macaroni penguins turn. It’s a bit different for the Macs as it would be impossible to count all of the chicks because of Big Mac- the largest colony on the island which has 40,000 pairs of Macaroni penguins. Instead Jerry and Ruth walk a transect through the colony counting chicks as they go.  For the chick weighing session everyone from base trudged over to Little Mac (the main study colony- of a much more manageable size),  apart from Jon who was looking after the base and his leg! We had to catch and weigh 100 chicks, and also issue them with a pit tag, which is the same as a microchip you would give to your cat or dog. The reason for the tags is that to access Little Mac colony the birds come through a narrow passage and have to cross the penguin weighbridge, that weighs them and scans their chips. To get the maximise use of the data we need as many penguins as possible to be chipped. 

February has been particularly exciting for me as the first Wandering albatross chick hatched on the 26th, after being incubated for 76 days. Of all the species on the island I have most been looking forward to the hatching of the Wanderers as I am going to get to spend the whole winter watching them grow up and finally fledge around December time.

Every day I have to go and check the nests to see which chicks have hatched, hopefully they should all have hatched in the next three weeks. For new born birds they are fairly big. They just about fit in my hand but won’t for much longer.

This month we did a search and rescue exercise to make sure that we all know what we are doing over the winter. At first I didn’t realise it was an exercise, so when Jen radioed to say she had fallen and thought she had broken her ankle, I thought she meant it! After a couple of minutes I remembered that we were supposed to be doing an exercise that week and relaxed a bit. Craig and Hannah were sent to assess the casualty, whilst Ruth and I got together the stretcher and splints. We then headed over to the far end of Main Bay with the stretcher, which is extremely awkward and heavy to carry. We made it eventually after both nearly falling over on the rocks and managed to get a splint on Jen’s leg and her onto the stretcher. We practiced carrying the stretcher with just three people, as in winter that will be all we have. We managed it, but Jen is pretty light. If one of the guys is the casualty I don’t think we are going to be able to carry them back to base and will probably have to pitch a tent and await help..... which might take a few days.

I’ve had a bit of spare time this month to do a bit of adventuring, and as we’ve had a few nice days I thought it would be worth getting up some of the peaks on the island. The first one was Tonk which I walk along the base of regularly. From the top you can see most of the island, apart from the bit behind La Roche (the highest peak). It was glorious being up there in the sun shine and with relatively little wind. I sat up there for a while watching the Wanderers and Light Mantled Sooty albatrosses wheeling past. I then decided to go and find a sooty chick as I hadn’t seen one before as they nest in fairly inaccessible places. Eventually I managed to find one. Sooty’s are renowned for being terrible are raising chicks. The vast majority of nests fail, so it’s a good job that they are so long lived otherwise I don’t think that they would last very long as a species. It was worth the look as the chick was very different to the other albatross chicks around the island, and looks as though it’s wearing a mask across its eyes.

The second adventure was a trip up La Roche, the islands highest peak. It isn’t all that high by mountain standards at 356m but you get great views of the whole island and South Georgia. Craig and I hiked up in increasingly worsening weather, it started off fairly nice but was snowing before long. At one point we thought about turning back as it was really windy and there are some narrow parts to traverse with big drops below. We found a ridge to hunker down behind, had some snacks and decided to go for it. Fairly close to the top I spotted an Antarctic Tern chick, which was very exciting as they are not common things to find. I suspected there might be a chick around as the adults had been screeching at us most of the way up, but I hadn’t expected to find it! We made it up to the top and had fairly good views and a lot of wind. We took a short cut on the way back down, straight down the scree slopes which was fun but I wouldn’t have wanted to go up that way.

I guess more things have happened in February that I thought......
