Last days of solitude.

With about a week to go until the new staff arrive on Bird Island I thought I'd try and squeeze in a quick blog while our internet isn't too busy. With first call imminent we've been rushing round cleaning and tidying, making space for deliveries and packing up waste and recycling to go off. Rooms and kit have been prepared so the incoming guys can get straight up to speed and we're enjoying the last few days of just the four of us. Craig will have a two-day changeover with the new technician and then head off down to Rothera, so this really is time to enjoy on the island.

Typically this business coincides with my busiest few weeks of the whole year, although I have now managed to get a bit of breathing space. In the last week I have finished off the nesting count of Gentoo penguins – two or more of us have been out to all the different colonies and counted the number of active nests, that is those containing penguins sitting on eggs. There's some small sections which are quite simple, and some areas of several hundred where we've had to agree on imaginary bisecting lines to split them into more manageable chunks. Then repeatedly count the nests within until we agree on a figure.

The other penguins, the Macaronis, are back in full force and can be heard all over that side of the island, arguing away over nesting territories. We've been weighing individuals as they come ashore, a simple test of how well they've been feeding over the winter.

Standard Bird Island weather - a million shades of grey with penguins as far as you can see.

My work with the Giant Petrels continues. The Northerns have all laid and the Southerns, who operate about a month behind them, are in the middle of doing so. I've met a few calm old birds who were ringed as chicks before I was born, which is always a little humbling.

There's two of these rare white-morph Southern Giant Petrels in my study area of around 140 pairs.

Many of the smaller petrels have also started returning and I've started checking their burrows, looking for individuals who have been carrying tiny geolocator devices over the winter. These have been tracking the birds movements and will help identify key feeding areas, hopefully leading to greater protection for them.

While most White-chinned Petrels land and head straight for a burrow, this one sat up on the tussoc, calling away.

Blue-eyed Shags are starting to build their nests so I've started keeping an eye on the small colony near base.

Very smart looking Blue-eyed Shag. Like shags in the UK that crest is only prominent at the beginning of the breeding season.

We've all been out helping Steph with some albatross surveys. First up was the ten-year census of the Grey-heads, which took us all over the island counting some huge and some tiny colonies of these beautiful birds. Soon we'll have to repeat our rounds of the areas counting the far more numerous Black-brows and the much rarer Light-mantled Sooties.

The Wandering Albatross chicks are close to fledging, with the best developed individuals now carrying very few downy chick feathers. I gave Steph a hand finishing off the ringing of them, barring a few left for the new albatross assistant.

Will this be the last time this Wandering Albatross family all see each other together?

The beaches are quickly becoming dangerous places to go as the male fur seals haul their way up and pick a spot where they will try and get a harem of females together. It's still early so there's been no fighting yet, just a few growls. The majority of the big guys are just sleeping, well aware that there are hard times coming up with a few scraps and little time for napping or feeding. Over on Landing Beach the two elephant seal pups are enjoying each others company as their mums head out to sea.
