Video Blog: Skomer Stories Ep. 1 - Seal Monitoring

We're very excited to announce a new project we've been working on - introducing Skomer Stories!

Our Visitor Officer, Rob, is filming a series of short videos on the island to give you an insight into the work we carry out and the wildlife we protect - all to give you a taste of Skomer from home.

Look out for plenty more of these in 2025 but for now, please enjoy episode 1, where he'll take you on

a seal round, help you identify males from females and talk about why this work is so vital - the island is closed to the public in autumn, so this is a unique insight into the autumnal sights of Skomer.

Presented as a video blog, this is a new way to keep up with our work on Skomer.

Island update - October

I have just spent six incredible weeks on Skomer Island assisting with their annual grey seal monitoring as part of a collaboration with Swansea University. During those six weeks I watched the lively island bustling with visitors, volunteers and Manx Shearwaters transform into a sleepy refuge for wildlife which I miss terribly.

My main role on the island was to count the seals at the six busiest sites on the island, as well as recording their sex and age category. This role certainly wasn’t glamorous, I spent many hours shuffling on my belly through grass and mud so that I remained hidden from timid groups of seals, but I loved every minute of it! As well as counting the seals, I photographed the distinct scarred seals I spotted and matched them up with photos from the island’s records. This was incredibly interesting work as I was able to identify seals by their scars or markings and see where they had been in previous years.

Hard at Work

With no visitors on the island, autumn is the season for repairs and construction. When I wasn’t counting seals, I got stuck into some tasks around the island and with so few people around an extra pair of hands was greatly appreciated. I assisted Visitor Officer Rob and Assistant Warden Ceris to prepare the Wick for the Winter. This involved removing the surprisingly heavy metal fenceposts, rope and benches from the Wick and taking them to the farm. During this task, I did go head-to-head with Rob in a wheelbarrow race, which I unfairly lost!

Gull Roost Count

Initially, Bird Log sounded like another language, and I would desperately try to understand the meanings of “chiffchaff at Moorey Mere” and “Dunnock at Captain Kites”. OxNav students Layla and Bridget and long-term volunteers Nick and Pete were all admirably patient with me and helped identify the birds I had seen that day from my puzzling descriptions. It didn’t take long for me to get hooked and I began spending hours wandering around the island searching for birds.

This newfound passion for birding meant I was excited to assist with the gull roost count on the island. To do this, Ceris, Will, Rob and I counted the number of gulls at known roost sites around the island as they arrived at dusk. It is important to record the number of gulls roosting for datasets are there has been growing concern over the decline in Great Black-backed gull populations in recent years. Great Black-backed gulls are now a red-listed species as their populations have declined by around 28% in Europe and 68% in North America.

My favourite birdwatching experiences on Skomer had to be watching the owls at dusk. After nights of listening to Rob and Ceris discussing the pellets they’d seen and sounds they’d heard; I finally spotted a stunning barn owl flying above North Valley Willows. I was also exceedingly envious of Nick and Amy who watched four short-eared owls as they flew near the farm, but I was eventually lucky enough to see some myself!

My Last Seal Round

My final seal round was an unforgettable farewell. After almost ten days of dwindling pup numbers at South Haven, I was delighted to see two exceedingly tiny yellow pups laying besides their enormous mothers. The sunny afternoon got even better when I arrived at Castle Bay to see my largest haul out yet, 110 seals on a single beach!

This was the perfect finish to the six extraordinary weeks I spent on Skomer. It was an honour and a privilege to work alongside some of the most devoted, knowledgeable and kind people I’ve ever met. I cannot wait to come back!

Skomer in September - Seabird Spectacular!

Ted and I are once again truly honoured to be asked to write a blog about our most recent visit to the most beautiful place on the planet.

For weeks we had been talking about the weather, hoping for a week of easterlies before we went, then switching to a west or northwest when we arrived as we really wanted to spend lots of time sea-watching. Little did we realise just how much of the latter we would do!

But the weather did exactly what we wanted.

Pretty early in the morning on Sat 7^th September we received a message from the very wonderful Ceris to say that there were no boats for at least five days, except for this afternoon at 3.30. Ted and I had to move so fast, nothing was ready, we hadn’t packed and we hadn’t shopped. We flew around the house (and loft) and an hour and a half later, we were off. We dived into the local supermarket where I’m sure the shoppers thought we were doing ‘Supermarket sweep’. No-one got hurt (we don’t think) as we flew around the aisles filling the trolley, we threw it in the car and drove.

With half an hour to spare we were on the beach at Martins Haven at 3pm having hastily packed the rucksacks at Marloes.

We met one of the young birders and then Beth came over the steps to meet us – amazing ! Soon we were on the Dale Queen with Carl + Co and our stunning destination came into view – emotional? Oh yes!

Onto the island, meeting the rest of the team – Ceris, Pete, Nick, Lisa, Will and more friendly and welcoming faces, it was so good to be back, in paradise with wonderful, warm, human beings 😊

Both Leighton and Rob were off island, with Rob doing the amazing thing of running a marathon for charity – well done Rob. And Leighton was off being Best Man- what a great person to be your best man!

There had apparently been a bit of a ‘fall’ of birds, so very quickly we were up to the Farm and we were birding. Indeed there were lots of birds, the bushes were positively jumping with small birds - warblers and flycatchers in particular.

It didn’t take Ted long to find the Wryneck that Ceris kept on seeing, perched in a bush in North Valley – how we love our Wrynecks.

There were lots and lots of Spotted Flycatchers and a few of the Pied variety too, one at North Valley crossing actually allowed for a pic or two to be taken.

We really didn’t have anywhere near long enough on this day to cover in depth what we wanted, but the Island already had us encapsulated once more 😊

We slept well !

Sunday 8^th was wet, very wet, for much of the day, so we camped out in the hide at North pond for a long while enjoying the 2 Dunlin and some White Wagtails, before helping out with some conservation work in the afternoon. As it dried up the birds popped out once more, with Whinchats being really evident, in fact they were throughout our stay.

We headed to South Plateau in the afternoon and spent some time casually looking out to sea, well it was casual until Ted picked up a BIG white bird flying south, Spoonbill and Egret went through his head until the reality set in, it was far rarer!! A Swan! Panic to try and get the scope on it, it was going south and going fast, luckily we got it. Nope, not an early Whooper but a Mute Swan. I’ve been visiting Skomer for many years and never seen a swan of any kind, this was mega!

We were also watching a pod of Common Dolphin around the Mew Stone, hunting and jumping out of the water – what a truly special place Skomer is 😊

Monday 9^th saw us casually walking past Green Pond in the day where we both glanced at a dark bird on the water, we looked a bit harder as we both realized it was a Coot, another great bird, Coots are unusual out here and neither of us had ever seen one here.

There were also 6 Teal on North Pond from dawn which were great to see up close.

We did some more work and then in the evening went sea watching at the Garland Stone as the wind had really got up, blowing from the northwest.

Things really started to kick off here, and were the start of the next few days of magical sea watching, making memories and brilliant life experiences!

There were terns going past, including Common, Sandwich and Arctic – more unusual birds, Arctic Skua and Scoters. Then a ghostly white tern came along, close in near the Garland Stone, surely not? Surely yes - a Roseate Tern. It even did the decent thing and flew alongside Common Terns, what a beauty.

This spurred us on for the next morning, the wind was increasing and so surely was our chances of decent seabirds.

The wind was due west and seriously strong, we knew we couldn’t sea watch at Skomer Head, way too exposed, so with Pete and Nick we tried at the Garland Stone, it was pretty bad here.

It was obvious pretty quickly that birds were passing to our west and there was little in the bay, so we moved further west between Pigstone Bay and Bull Hole and tried to hide behind some rocks, it was so difficult to get out of the wind. But birds were moving south and soon Ted picked up a lovely pale phase Pomarine Skua. Pete and Nick had to go, but despite being hammered by the wind we knew we had to stick it out.

It wasn’t too long before Ted pulled another rabbit out of the hat, well a Shearwater out of the sea to be more accurate, and one of the Balearic variety at that, a fantastic bird.  

Not long after, I picked up a bird sitting on the sea, initially my brain just couldn’t work it out, then it finally clicked it was a Shearwater, but it looked massive, then a Manxie flew over it, the bird was huge, indeed it was - Boom !!!  – A Great Shearwater, and it was sitting on the sea, not too far out. Total adrenalin rush at this point. Between us we made sure that one of us was always locked on it, as the other tried to get photos. I then somehow managed to ring Ceris whilst keeping my eye in my scope eyepiece, it was a brief conversation! I didn’t hear what happened at Ceris’s end, but Ceris told us later - Ceris was briefing the volunteers when she took my call, then she said something like – CHANGE OF PLAN – Run !

It didn’t take long until the first footsteps were running up behind us and soon nearly everyone on the island was looking at the Great Shearwater. We later found out that this was the first Skomer record for 30 years.

The morning of the 11^th was going to be our extended seawatch day, and with Ceris, Will, Beth and Lisa we camped out at Skomer Head – it was exciting. Skuas, ducks, auks, waders, all going past in spectacular seas. Then Ted ………. did it again !!!!!!

Somehow Ted found and then stayed locked onto a juvenile Sabines Gull – Wow, just wow, but none of us could get on it. Then it settled on the sea, we still couldn’t get on it.  I simply can’t describe the pain and frustration as 5 good birders tried and tried and tried - it just shows how difficult sea watching is. But in the end we managed it with Ted's considerable help, and it flew around with it’s Kittiwake chums, somehow Ted even got some photos – I simply don’t know how.

The young birders arrived, they were happy, everyone was happy.

It wasn’t a difficult decision where to be at dawn on the 12^th - Skomer Head of course!

We enjoyed lots more seabird passage including more Skuas, some really close, lots and lots of terns, significant numbers for Skomer. Also divers going south and a Bar-tailed Godwit going north-west.

We watched as a huge passage of Kittiwakes came past us out of Broad Sound, with an estimated 4000 in only 90 minutes.

Other exciting news - Rob returned 😊It was great to see him!

Fri 13^th dawned clear, bright and beautiful, the wind had dropped to virtually nothing, we had less than 2 hours to the boat.

We bashed around as quickly as we could, watching a Water Rail run down the length of North Pond and a Grasshopper Warbler pop up in the vegetation there, this was our parting gift.

All too soon (it’s always too soon) we were saying our goodbyes with heavy hearts, to our little bit of paradise on Planet Earth, and to the most amazing, wonderful people 😊

It’ll soon be May …………😊😊😊

Island Update - Late September

 As we pass the equinox, it’s officially autumn. The nights are drawing in and the temperatures are dropping. Skomer is transitioning in to end of season jobs and warm sunny days are now a mere memory.

September jobs

Autumn on Skomer is the time to do repairs and construction. Benches, fences, signs, dams, and more which have survived the previous year are in need of some touching up before the winter.

With there only being one boat per day, if there are any at all with the weather, the weekly volunteers are giving helping hands around the island fixing up paths, clearing vegetation, and other general DIY. Wooden doors, signs, walls, fences, and benches have all been treated with preserver, along with the sales point and landing. Paths at the Wick have been widened as the grass had grown over, rotting benches have been replaced, and brambles around the farm have been cleared, to name just a few tasks.

The volunteers aren’t the only people learning new skills this month; our assistant warden Ceris has been hard at work getting street savvy with some gen-z lingo. She described the application of wood preserver at the sales point as “That fence is giving, you guys ate and left no crumbs. Slay” (translating to “That fence looks amazing, you guys did an amazing job, well done”).

Ceris and some weekly volunteers inspecting Nick and Pete’s painting work. It’s definitely slay.

Sunrise barge day

In preparation for all the construction and repair work going on in the last few weeks, we had our second barge day of the season. With the early high tide, this meant being ready at 6am for a long day of hauling and organising the components of a new kitchen, two new bathrooms, a dam repair, and so much more. The rest of the barge load comprised of several tonnes of sand, aggregate, concrete, large stacks of wood, and over a dozen full gas bottles. There was also plenty of old construction waste, empty gas bottles and more to leave the island.

Work party and building work

All this material was brought on for several construction and repair jobs, with the refitting of the hostel kitchen and bathrooms being the main project. Six volunteers have come to the week as a work party to prepare the hostel for builders to come, amongst other jobs across the island. For the last week, the farm has been a bustling construction site.

North Valley Willows Improvements

On the topic of construction projects, our LTVs Nick and Pete have recently finished a project putting in two new sections of boardwalk at North Valley Willows near Green Pond. Along with the boardwalks, paths were cleared and a falling branch was propped back up.

The ground was so clay-like whilst digging the supports in, we were able to make “Clayton” the warden in mud form.

Sunrise Spoonbills

Autumn migrants are still passing through, with conspiracies of Ravens and charms of Goldfinch gracing Skomer with their presence. We were delighted to have Dave Astins of West Coast Birdwatching lead a bird watching group for three days. Plenty of birding highlights were enjoyed with the regular array of Spotted Flycatchers, Chiffchaff, Willow Warblers, Greenland Wheatear, Snipe, Dunlin, Whinchat, Blackcaps, and plenty more. Some of the special sightings were Hobby, Common Rosefinch, and an amazing display of seven Spoonbill which flew over the island and circled back four times.

More Skomer yoga!

As our events season comes to a close, we finished the programme with our final yoga retreat, lead by Ady. With moonrise sessions at the garland stone, and sunrise at the trig point, the group enjoyed a wide range of breathing and mindfulness exercises across the island. Booking for events next year will soon be advertised on our website.

Colossal cumulonimbi and Stunning sun dogs

Clouds have been something I have always loved, and here on Skomer, we’ve had some beautiful skies. My brother has a good quote “clouds are the most under appreciated form of natural beauty in my opinion” which I completely agree with. You can always look up at the sky and know something about what’s going on up there. Even a grey featureless blanket, or an empty blue sky, tells you so much about the weather and how the atmosphere is acting, which is fascinating.

Autumn is a great time for cloud and weather watching. With storms mixed in with fair weather, you can see a great variety of cloud types and have a wonderful array of sunrises and sunsets.

Harvest time at the farm!

Rob’s veg patch at the farm has had a magnificent crop this year. Thanks to his hard work and the fertile soils of Skomer, several collections of courgettes, beetroots, and salads have been made over the last few months. Last week, Rob had his largest single harvest with 10kg of rhubarb, salad, potatoes, carrots, courgettes, beetroots and parsnips. However, the crowning glory and winner of “Largest Skomer vegetable of the season (and probably all seasons prior and to come)” was his 2kg marrow. This is a particularly impressive vegetable as it has been a bumper year for slugs, with the mild and moist season forming a perfect slug-fest with one pumpkin and several potatoes already succumbed to the hordes of gastropods. When Rob noticed a particularly large courgette one morning, he decided to see how large it could grow. Either, it would grow large and act as a decoy veggie so all the slugs and snails would target one individual instead of lightly grazing upon the entire garden, or the courgette would evolve into a giant prize-winning marrow and Rob would have a delicious dinner, win-win!

Investigating the strength of Nettles

Many of Skomer’s visitors and residents have commented on the high strength of the Common Nettles (Urtica dioica) found on Skomer, with some people still in pain days after being stung. In 2022, when Sir David Attenborough visited for the filming of Wild Isles, he sat at the sales point and got stung, saying “You have very strong nettles here”. To try and answer the question of how much stronger they are, Nick carried out a short and highly simplified investigation in their free time.

The stinging needles of the Nettle

The literature doesn’t have much on the varying strengths of Nettles, but Kato et al. (2008) from Nara Women’s University in Japan published a paper on “The evolution of nettle resistance to heavy deer browsing”. In the paper, it was found that the nettles in Nara Park had a much higher needle density as they were being subjected to high intensity grazing by the Sika Deer. This could also be the reason why the nettles on Skomer might be stronger than the ‘average’ nettle due to the high grazing Rabbit population. This paper was used as a rough guide to form a small study on how needle density varies on Skomer, compared to other locations.

Three locations had samples taken; Martin’s Haven on the mainland (as a rough off-island comparison), the farm at the centre of Skomer (one of the highest grazing densities on the island), and the sales point in North Haven (more specifically, the very bush which stung Sir David to get the quote mentioned above). The results were far from significant, but had a measurable difference

Average needle density shown at the three different sites with both the upper side (a) and under side (b) counts shown. 

It showed that Skomer’s nettles had a slightly higher needle density compared to the mainland, but not by a considerable margin. A reliably sourced figure for the average needle density of U. dioica was not found, so a comparison to needle density further afield than the far West of Pembrokeshire could not be calculated. A more reliable figure and distribution of needle density on Skomer could be carried through a much more thorough investigation, but it’s interesting to see what could be found through a little looking!

Autumn tides

As we passed the equinox, doubled with a full supermoon, the tides have been extra strong recently. On the 20th September, the tidal range on Skomer was an amazing 7m. On particularly low tides, when you’ve finished swimming the water will sometimes be considerably below the bottom step.

Emma arrives on Skomer

We’re excited to welcome Emma to the island until mid October. She will be helping with the seal research that’s taking place, mainly on the Neck. She will be helping with the regular counts of hauled out pups and adults, along with looking at individual Seal’s scars and patterns to match up with database images. This information will allow us to know where these seals have been seen in previous years to look at site fidelity (the tendency for an animal to return to previously visited locations).

Emma photographing seals from the Isthmus

At around 100 or so Seal pups already, the pupping season is well underway. The Seals haunting sounds of “AwooOOooOoooo” and “WfuuuguaaaahhHHH” amongst a wide variety of others can be heard from across the entire island. On still mornings you can often hear them from the farm drifting across the fields. Extra atmospheric if it’s a heavy mist or low cloud! The Seal pups make a much more toddler-like sounds which can be very disconcerting when you hear it echoing amongst the sea caves. Haul outs across the island are continuing to rise in numbers with Castle Bay regularly having over 30 Seals.

Departing LTVs

As we come to end of September, this sadly means the departure of our two long-term volunteers Nick and Pete, who have been with us since the start of July. As a thank you, Rob our Visitor Officer, and Ceris our Assistant Warden, took both of them, along with Emma our Seal Researcher, out for a boat trip around the island. It was amazing to see the island from a completely different perspective and gave a whole new appreciation for the island. Wildlife highlights included great views of Razorbills and a Guillemot in winter plumage, and plenty of Gannets passing right past us, with some going overhead.

As we say goodbye to our long-term volunteers, weekly volunteers, and day visitors until next spring, Skomer is wrapping up the season and preparing for the winter.
