Riding the waves; tough weather for penguins


The Macaroni Penguins are hanging round the colonies in smaller and smaller numbers - today only 115 in Little Mac where at peak breeding there would be 350+ pairs. There's still birds coming in and out of the colony mind, and with a stiff northerly wind creating some big waves it's not easy.

Here's some photos of these tough little buggers getting in and out of the water:

When the swell drops it looks a long way down. Rest assured 2 seconds later these penguins will be trading places. 
This isn't the best photo but is worth looking at to see the penguin that has most mistimed its leap out the sea.


Amongst the penguin action a group of Fur Seals headed past, leaping high over the crashing waves.
Up on dry land the Macs did a bit of nest building. Why? They'll be gone in a few weeks, headed out to sea until October. Perhaps inbuilt territorial behaviour, perhaps trying to impress a potential mate.

Although they are incredibly noisy and violent I'll really miss these little guys. They're so charismatic and how can you not be impressed by those eyebrows.

An intimate moment as one has a scratch, lifting a foot to the scratch the side of it's head, wobbling endearingly as it does so.

Winter arrives.


In the last week we've had an early taste of what winter promises. An icy wind has blown up from the continent, covering the island in a layer of snow, making skating rinks of the ponds and making the streams a lot more interesting to climb.
We have managed a few clear days through which to appreciate this weather so here are a few photos:

The view from Gazella, looking down to the base and the cove. Tonk and Molly Hill make up the ridge on this side of the island.
Another blizzard approaching across the sea. It's nice to see them coming so you can check you've got hat, goggles, shelter etc.
Fur Seals love the snow, sliding around and rolling over and over in it.
The view from Tonk, looking down toward base and across to the South Georgia mainland.
More seals enjoying the snow. These were pretty far up the slopes, I suspect planning on sliding all the way down to the sea on their bellies.
Macaroni Penguins, not particularly bothered by the snow. In fact they were raising their beaks skyward to catch flakes, then scooping mouthfuls off their backs when it built up.
Wandering Albatross with small chick, enjoying a respite from the constant wind.
The dangerous and reckless sport of danger walking. Not quite so reckless when you know the pond in question is only 6 inches deep. 
Cold days can mean clear nights, though with a bright moon about we're still waiting for the best star-spotting nights.

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.

Wading through mud and crap to count Gentoos at Square Pond.

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.

Observations being made by both parties.

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.

Return of the Macs

While the Gentoo Penguins have been around all winter, although in much larger numbers recently, the Macaronis have been out at sea since April.

I've been out preparing for their return - painting and measuring transect lines within the colony that we'll use to estimate numbers and setting up the gateway that weighs them as they return to feed young.

The return date of the Macs is pretty consistent year to year so I knew that when I was out doing some measuring there was a good chance I'd see the first one back. And so I did. There it was, standing half way up the colony looking nice and clean with big impressive eyebrows.

Numbers seemed to double each day for the next week until the colony was swarming and bustling with birds. These will be the males, returning first to establish sites and build nests. The females are out at sea still, feeding up so they've got the energy reserves to lay their eggs. They'll be back in the next fortnight though.

It's been pretty rough the last few days with some big swell and waves smashing over the rocks. That hasn't stopped the tough little Macs though. Neither has the Leopard Seal patrolling at the bottom of Big Mac. You have to admire their resilience as they ride the waves up the rocks, struggling to get a foothold before it ebbs back and drags them down past the kelp and into the danger zone.

Once up on the rocks they have a shake and a preen. Check their feathers are still in order and they're looking good and then start walking up the narrow route onto the wider 'motorway' up through the colony and back to their nest site where they can start shifting rocks around and arguing with the neighbours.

Made it!
