Welcome back to the final installment of Reindeer Around the World! For the last blog in the series we’re travelling west to look at the four subspecies of Caribou that cover Canada, Greenland and a few northern states and Alaska of the USA. So firstly, are caribou and reindeer the same animal? Short answer, yes. Long answer, no, they’re not.
The caribou: similar in nearly everyway to the Eurasian tundra and forest reindeer.
In North America, the reindeer populations are seen as two difference categories of animals: semi domesticated = reindeer, and wild = caribou. But from an ecological stand point, the caribou are broken down into four subspecies:
You’ll notice the similarity in scientific name with the European subspecies of reindeer we’ve previously looked at, confirming they are the same species, but each have slight differences. So, what makes each subspecies of caribou different to each other, and to the reindeer we know and love here in Scotland.

The Porcupine caribou closely resembles the barren-ground caribou, covering similar landscapes in the northern most territories seen on the above map. They cover a calving ground based on a river system including the Porcupine River – hence the name. They have a darker colouration to them, but their environmental adaptations and ecosystem role are what we’re familiar with throughout the other subspecies of reindeer we’ve been looking into.

The woodland caribou is again very similar to what we imagine when we picture our tundra reindeer here at home. Adaptations for sub arctic habitats, dealing with deep snow and harsh temperatures, keeping on the move and fulfilling the same ecosystem role. The differences we know of with the woodland caribou are more to do with diet, it seems, than anything else. Inhabitating a lot of areas of old growth forest and smaller herds found in different rugid mountain ranges further south than any of the other populations, they have different species of fauna available to them to feed off. The woodland caribou feed almost exclusively from aboreal lichens for the colder half of the year, followed by dried grasses and some tree species throughout the warmer months.
An example of aboreal lichen, growing along the bark of a tree as opposed to carpets of lichen on the ground. These types of lichen are found at a lower altitude than the rocky mountainous ranges we expect to find reindeer, where they typically live above treelines amongst far shorter growing vegetation such as grasses and heathers.
The Peary caribou are the smallest subspecies of caribou and are found in much smaller herds than any other. During winter time you are most likely only going to find up to four of them travelling together and this expands to maybe a dozen during the summer months. They feed on similar plant life to the other subspecies, having limited choice due to their sub arctic and arctic home ranges. But unlike the others, they predominantly feed on purple saxifrage which can stain their noses with a purple tint. Their migratory path is not as large as other subspecies of caribou, moving up to 150km between winter and summer home ranges, sometimes between islands (seen on the map above as number 6). Similarly to the others they are ready for anything winter can throw at them, but do choose to avoid areas of very deep and heavy snow, retreating instead to rocky mountainous outcroppings and beached areas.

Finally, the last animal on our list to discuss… The barren-ground caribou. Maybe the best to last if that’s fair to say. Let’s meet the animal with the largest ground migratory path in the world! You heard that right, a bigger migration even than the wildebeest in the Serengeti. They migrate twice a year between summer and winter ranges with each journey potentially covering more than 1,000 km depending on the location of their calving grounds. They use higher spots for calving grounds, out of reach of predators such as the wolf, then descend to lower ground and migrate in large herds to areas for summer grazing. Their winter diet consits of some grasses, lichen and leaves from low growth trees. They share their other qualities and adaptations with the other subspecies of caribou, making them efficent at moving and feeding through shallow snow and coping with cold temperatures found in arctic regions.

And there we have it – we’ve learnt all about the different subspecies of reindeer all across the globe! Thanks for sticking with me, and I hope you’ve all enjoyed reading this blog series as much as I’ve enjoyed researching it. I feel it’s important to say there are other indivdual named herds that I haven’t covered, but to learn about the different adaptations and qualities, I think we’ve got all bases covered. Reindeer truly are a remarkable and wonderful animal, with clearly a lot more to them as a species than we may first realise.
The bodies of reindeer go through many changes allowing them to cope with huge temperature difference throughout the seasons. In summer reindeer can cope with temperatures above 30 degrees and the lowest recorded temperature that reindeer have been know to survive is -72 degrees Celsius. Reindeer have two different coats, a thick white winter coat as well as a fine, dark summer coat. Their antlers grow in an annual cycle and the different times of growing and shedding them allows different animals to be dominant at different times of year. One of the most interesting, and important, changes to a reindeer though, you can’t see – their metabolism.

Reindeer have adapted to eat vast amounts of food throughout the spring, summer and autumn to gain enough weight to survive the winter, when food is scarce. To cope with these changes in food availability their metabolism changes too. In the summer reindeer will graze around the clock, eating a huge variety (between 200 and 300 different species) of plants which are high in nutrition. This allows each individual to grow a new set of antlers, they start to grow in the spring and are fully grown by the end of august and the heaviest set we have had in our herd, weighed a whopping 8.9 kgs. The summer is also the time that the young reindeer grow in body size. Finally, every reindeer will need to gain body fat which will act as reserves over the winter. All these things require their digestive system to work in overdrive converting the food they are eating into energy that can be used by their body to create protein, bone, fat, and whatever is needed.

On the contrary, winter is all about survival. During the winter most of the plants will have died under the snow and 70% of a reindeer’s diet is made up of lichen. Lichen is a symbiosis of fungi and algae and is very resistant to extreme changes in temperature. Over the winter lichen won’t grow but it will stay dormant, preserved under the snow. Reindeer will then dig down through the snow to reach the lichen. But lichen is relatively low in nutrients, just enough to sustain the reindeer through the winter and their metabolism shifts in line with this. In fact, even if you gave a reindeer a big pile of food, during the winter, they just aren’t as hungry and wouldn’t eat it all.

During the winter reindeer are no longer growing their antlers, they won’t increase their body size at all, a calf will grow lots in the first 6 months of their life and then stay the same size for the next 5 months, until the following spring. They will survive the winter by using their fat reserves. The one important growth that does happen in winter is that of a growing foetus. This is the reason that the females grow antlers and keep them after the males have shed them, as it gives them a physical advantage during the time that they are pregnant and therefore they get first dibs on the food.

But how does a reindeer know that it’s time for spring? Rather than responding to food availability or temperature which may well change year by year, the changes in their metabolism are triggered by the changes in daylight. The increased daylight associated with spring is detected by specialised receptor cells in their eyes which then convert to a hormonal signal using melatonin. Melatonin is synthesised during the dark period each day and then synthesis stops during daylight. This means that the amount of melatonin varies based on the time of year. The concentration of melatonin has many effects. In terms of metabolism, in the spring as melatonin decreases, this increases the appetite of the reindeer. In the autumn, as melatonin increases, this decreases the appetite of the reindeer and increases the breakdown of fat stores. The changing melatonin levels also controls their antler growth and release of sex-hormones but that may be another blog in the future.

For anyone particularly interested in a much more in-depth description of the physiology behind these changes, I would highly recommend reading this article.
If you have made it this far, thanks for reading my very nerdy reindeer biology blog! Hopefully you have learnt something and enjoyed the pictures of the reindeer along the way.

Continuing on from learning about the lovely Svalbard reindeer (we all remember how cute those guys are!), this time we’ll look at the two other European subspecies of reindeer, the forest and tundra reindeer. Starting with the tundra reindeer…
Our very own tundra reindeer, Chickpea and Morven roaming the Cairngorm mountains.
Found across Northern Scandinavia and across Northern Russia with a large population in Siberia. They are also found here in the Highlands of Scotland roaming the Cairngorm mountain plateau. The southern most population on continental Europe is found in the mountain regions of Norway, however it is quite tricky to know where the tundra reindeer population ends and the forest reindeer population begins.
Forest reindeer grazing amongst trees.
The most notable population of forest reindeer is found surrounding the Karelia region, near the border of Finland and Russia. The population is then further wide spread across Russia.
Population map of all subspecies of reindeer, including the N.American caribou populations and the European domestic and wild populations. (Map source: found at the bottom of the image)
Unlike the Svalbard reindeer, these subspecies do follow a larger migratory pattern, and will usually cover anywhere from 12 – 34 miles per day. They move between areas following the availability of vegetation and to avoid the harshest environments during winter months.
The herds will also move alongside humans. Both species are heavily domesticated and have been for over 10,000 years now. Not only are the reindeer used for food, income, and general way of life by indigenous communities (most noteably in Europe – the Inari Sámi), but the reindeer themselves benefit. Knowledge passed down through generations regarding migratory behaviour, and the animals role in the ecosystem means a huge positvie impact on Arctic conservation. This not only benefits the domestic populations of reindeer, but also the wild ones, as well as all other forms of life living in these ecosystems.

The vast numbers of these two subspecies, the distribution of their population, and their movement patterns, give them a much larger impact on the ecosystem than the Svalbard reindeer. With grazing habbits helping to maintain Arctic tundra, it prevents the release of stored carbon in the permafrost. Being farmed in the traditional methods that they are – constantly moving, following the behaviour of the reindeer rather than using other methods of stationary farming – the reindeer are still able to exhibit their natural behaviour. It has also maintained a positive coexsistence between man and the fragile Arctic ecosystem.
Moving home and following the natural behavioural patterns of the reindeer.
This means that the reindeer have not needed to adapt to a stationary lifestyle. Their bodies are still designed to cover large distances and they remain successfully adapted to their role in the ecosystem – dispersing seeds in the trampled ground they’ve moved over.
Something they have adapted for over the last 10,000 years though, is sledge pulling.
Bigger males, often castrated herd members will be used to pull belongings when following the reindeers migratory habits.
Due to living alongside humans for such a long period of time, the European tundra and forest reindeer are semi domesticated. They don’t perceive humans as a threat and are very accumstomed to interacting with people and being handled. This means their strength and good hoof structure can be utilised for sled pulling.
Reindeer toes!
During the winter months, their footpads will shrink and tighten, this exposes the edge of the hoof and allows them to dig it in to the snow. They’ll maintain grip for descending and ascending hills/mountains, and still be able to run at high speeds without the risk of losing their footing. Their strong and muscular build, easy going/ docile nature, and drive for yummy rewards(!) makes them the perfect Arctic sled pulling animal. Second to the sled dog of course, also having worked alongside humans for approximately 8 – 10,000 years (I don’t think anyone could be happier pulling a sled than those guys!).
Keeping tradition alive. Our very own reindeer pulling sleds here in the Cairngorms. (Photo credit: Alex Smith) Our wonderful boys Zoom and Mivvi pulling a wheeled sleigh through Glenmore.
So, in summary, it seems the main adaptations for the European tundra and forest reindeer are behavioural more than physical. They have adapated to be more docile around humans, whilst still maintaining their natural drive to move. Not only for their benefit of chasing good grazing, but also for the benefit of the ecosystem – keeping the Arctic environment healthy.
Next time we’ll jump over 4000 miles from Europe to North America, and find out what the difference is between a reindeer and a caribou (if any).

Up and moving from Kent to Glenmore to live amongst the reindeer hasn’t just been a big change for me, but also for my dog, Echo. He’s certainly used to the outdoor lifestyle, having spent most of his life on hiking holidays and the last three years living in a van. But this new chapter for him has meant daily hikes, new friends, and endless adventures!
I’ve made it to the home of the reindeer!
Parking up in our camper after my first day of work, it was time for Echo to meet his new neighbours. He spent a decent hour that evening watching the reindeer through the door, desperately trying to spy antlers through the trees.
My first glimpse of my new neighbours.
Echo was very excited to be introduced to the official team of Reindeer Dogs, and swiftly made good friends, and found some new adventure buddies.
Many hikes up Meall a’Bhuachaille with Fraoch, the world’s fastest dog and must be the record holder for Meall a’Bhuachaille summits! Including sunrises up there before the herders head off into the hills in search of reindeer.Lots of walks spent with Ginger (I always have to look my best when Ginger’s here!).
Shortly after we arrived in Glenmore, someone else was quick to join Reindeer House… Sanna the pup. Sanna instantly took to Echo, and it was lovely to see him playing with a puppy in his older years.
Playing with my new pal and the newest reindeer dog.
Echo quickly fell into the routine of his new life – spending time around the Centre while I was working, and hiking in the hills in our free time.
Getting to work straight away! My first day on the job helping wash the Hill Trip welly’s.Helping herder Kate put up bat boxes in the reindeers woodland paddock. Helping eat – I mean make – the reindeer food.Looking for reindeer.Exploring more of the reindeers home range.
Echo soon got to enjoy the benefits of his new life here in the Cairngorms, including lots of lovely antlers to chew, and lots of fuss and exercise with the herders.
Unlimited antlers!Posing with my best pal on a hike with herder Maisy. Loving life in the snow with Sheena and Zoë!Visiting the reindeer and making sure I was on my best behaviour.
Echo even put in a shift on Christmas Eve, keeping us herders’ company all day and meeting all our lovely visitors while getting into the Christmas spirit with antlers of his own! He even made it onto Trip Advisor – 5 stars of course.
Christmas Eve is hard work at the Reindeer Centre.Christmas Eve Crew – I even got to meet Santa!!
As the new year began, six months into our new lives here in the Cairngorms, the biggest change arrived. I had loved seeing how healthy and happy Echo was here – especially playing with his new pals and enjoying spending time with the lovely Sanna, that I made the decision to expand our mini family. Echo was no longer the newest addition to the Reindeer Dogs…
Snoozing with my new sister on her first day home.
Meet Asta! It didn’t take long for her to fall in love with our home and all her new pals (Echo being the best thing since sliced bread, and Sanna a close second!). Now Echo gets to show her the ropes around the Centre – including where all the best spots for finding reindeer food to hoover up are, and where all the antlers are kept!
Asta’s first day at work.
I’m looking forward to seeing what she thinks of the reindeer when she finally spots them from afar, and all the adventures her and Echo will have with their pals over the coming summer and beyond. The Reindeer Dogs are a very lucky bunch, and it’s so lovely for Echo and Asta to get to be apart of the gang!

Since the first week of January, our wonderful herd of reindeer have been out free – ranging the mountains. Our females and smaller male calves from last Spring roamed the hills here in the Cairngorms, while our males, bigger male calves and their mums free roamed the hills not too far from our farm. Free – range season is a chance for all our reindeer to enjoy the good grazing and open plains of the sub-arctic tundra we find ourselves in here, and to grab a well earned rest after our busy Christmas season.
Free – ranging season provides the most stunning views of the reindeer with the backdrop of the beautiful Cairngorm mountains.
It’s also a fantastic time of year for us herders, getting to move the reindeer around the hills every morning, and take guests out to see them in their natural habitat with no fences. So, as free – range season draws to a close for 2026, it’s time to look back on our herders favorite moments.
Can you spot the herder amongst the herd?…
Lotti
Looking back over the last few months, one morning fetching the reindeer immediately sprung to mind as a highlight. To set the scene, the previous day, Andi and I had fetched the reindeer for the morning visit, and both agreed that the reindeer had been slower and more difficult to herd than either of us had EVER seen! Fast forward to the following day, I was feeling tired and whilst the morning walk out to find the reindeer is usually my favourite job, after the day before I was quite happy to do a hill trip instead. But alas, it was not meant to be. As it turned out Daisy was the only herder with enough beans to volunteer to walk out to find the reindeer. At this time of year it takes two of us, one at the front and one at the back, so reluctantly I joined her.
Poor Daisy had to cope with a distinct lack of enthusiasm from me on the walk out which finished with an uphill, off path trudge through the snow. When we reached the top of the hill though, we were greeted with the most wonderful sight, the herd on a snowy hillside with the beautiful mountains of the Cairngorm’s behind them. I have lived and worked here for a wee while, but a view like this still has the ability to take my breath away – I hope that never changes.
Of course, on that day the reindeer were good as gold, and we had the most wonderful time walking them in. I often find that the days when I’m feeling less joie de vivre than usual are the days that the reindeer and the mountains really show off and have the ability to completely change my mood. I couldn’t wipe the grin off my face for the rest of the day!

Amy
My favorite day from this winter free range was collecting the reindeer at the start of March. Myself and Hen had walked out to where the reindeer where and it was decided that I would be the person that would walk infront of the reindeer and lure them to the visit spot, whilst Hen would stay at the back of the herd and make sure that we didn’t leave any stragglers behind. At the front I could see that lovely Vienna was very determinedly trudging up the hill behind me, along with the sweetheart that is Ryvita, plus Christie and Cheer had taken a small group of reindeer on a questionable detour into a snowy crevice and Bordeaux was walking off very purposefully in the completely wrong direction. Given Bordeaux’s nature, it is very unusual for her to decide that she isn’t going to follow the herd, so I sat back for a brief second to see how things were going to play out and Bordeaux continued in the direction she was heading- away from myself.
Eventually, I rustled the white bag of hand-feed I was carrying to see if I could catch her attention and then it became evident that Bordeaux was confused about what direction I was going in. You could quite literally see in her face the moment she realised where I was and that I wasn’t in the direction she was expecting. I also loved the urgency she had when she walked off in the wrong direction, there was so much hope that just over the skyline she would be able to snack on some yummy handfood.
Whilst we were waiting for Bordeaux, Vienna is trying to persuade me to give up some hand feed.
Hen
My memory links directly to Amy’s, as I trailed along at the back of the herd keeping them moving in the right direction, like a sheepdog. Unfortunately my short stumpy legs cannot go uphill nearly as fast as a reindeer – or downhill, to be honest – so this role is often somewhat unneccessary when they are moving well as I’m struggling to keep up and can’t do much about stopping them going in the wrong direction anyway. On this particular day the herd had been quite hard work already, really preferring to stay put grazing, but once they were finally moving I clocked Bordeaux heading off in the wrong direction, leading multiple other reindeer with her. We were crossing a really rocky bit of ground and Amy was partway down the hill the other side already, and I remember yelling something rude at Bordeaux… Perhaps she realised at that point she was going the wrong way, or perhaps she’s well-versed in my swearing, but a minute or two later she appeared back in sight, now heading the right way…
I’m not sure this is necessarily my favourite memory, but it’s the one springing to mind right now, and the morning is one I actually have a photo from (although involving the random dog-leg of Bordeaux’s route).
Andi
My highlight of this year’s free-range season was fetching the herd from high on the mountain in a white-out, and having to use a compass bearing to navigate our way down out of the cloud – the first time in my 15 years of herding that I’ve had to rely on a compass whilst leading the herd! You will find out more about that experience in a few months time… keep following the blog!

One of my most memorable moments from my first free-range season has to be the wild weather Saturday of moving reindeer in a blizzard! The day had started with hardly any clouds and blue skies when I first dropped Cam and Sheena off to move the reindeer that morning. But, by the time Andi, Emm and I set off for the Hill Trip, a white out blizzard had struck. I only managed to locate Cam and Sheena thanks to their bright waterproofs! As I waited for Andi, Emm and the Hill Trip guests enough snow had settled against my ski googles that I could hardly see past Juniper stood next to me. The snow was quite short lived though and the guests had the most amazing blue skies and calm breeze with a fresh layer of snow settled on the reindeer for their trip. The hills looked amazing!
After the guests had gone we had the task of moving the reindeer across flats, jump a burn, over the road, and up onto a new set of hills. We set off as the mornings blizzard returned and the winds picked up! It was my second go of leading the reindeer, and seemed quite daunting given the lack of visibility. But the combination of Andi’s hand signals from the back of the herd and Ryvita leading the charge and following my calls, meant we successfully crossed the burn and got them up onto the road. With a cluster of cars parked up in the middle of the road, everyone hanging out their windows to record the reindeer – the entire female herd of 73 steadily came into view as they ran across the road and up onto the bank of the next hill in a quick single file. I never get over how fantastic it is to see the reindeer rush over the road, and how excited all of the passing drivers are, but with the snow falling and having just herded them through a blizzard – it was pure magic. From there it was up onto the flat of the next hill and to give the reindeer some well deserved food, and then back to the centre for a hot cup of tea (and several custard creams)!

My favourite moment in this winter free range was when Cam and I went out to fetch reindeer for the morning visit at the start of April. It was a stunner of a day with most of the snow gone which was meant to make it easy walking, however Cam decided to take us through deap heather and across a large river from the snow melt. Thank god I had my big wellies on! We headed along then up to where we thought the reindeer were. We arrived for where we last spied the herd, but they were nowhere to be seen. We had lost our 73 reindeer! I thought they had gone back the way we came, but Cam said that they probably carried on round the side of the hill. I suggested for us to split up to cover more area, so off we went in oposite directions with our walkie talkies turned on. All I could hear as I was walking back round the direction we came from was silence from Cams end. I was thinking about heading back and looking else where until I saw them! I was right. Cam was wrong… The reindeer had gone the way we wanted them to. Cam made us walk straight past them! Once Cam evantually caught me up with the reindeer (he took ages), I lead the herd up towards the visit spot (this was actually my first time leading reindeer on the free range!). Some were more enthusiastic than others to follow. We made it to the spot and awaited for Daisy’s arrival in the sun (which took longer than expected as she also got lost… what can you do?).
Can you spot Cam miles in the distance?…

Erm… That’s not how I remember it!
Editor’s Note: This is all we could get out of Cam for his offical response.

Being an old timer when it comes to reindeer herding I often end up leading the herd in for their morning feed rather than being the sheep dog at the back to keep them moving. This year we had a few newbies herders join our team and this was their first winter fetching reindeer so I took this on board and mostly lead the herd, even though everyone’s favourite job is at the back. At the back you just get to hang out, at a sensible pace and you don’t have to choose the route so when given the choice this is where most herders would want to be. Mid March I went out with Amy (another old timer) and this time I didn’t give her the choice, I opted for following along at the back. It was a glorious day, blue skies, sunshine and snow… Just perfect! I spent most of the time taking videos and photo’s and sending them to everyone I knew working an office job that day boasting about my morning. It’s days like this that make you forget about the wet, windy and claggy days that end up being a total mission and therefore restoring your faith in Scottish winters!
Nice butt(s)!

Free-range season is a real mix. The weather can be truly awful, and on days the reindeer are feeling stubborn, moving them can be a long and difficult slog. But sometimes, you get a bluebird day when the sun is out and the reindeer are hungry and cooperative, and these are some of my favourite mornings throughout the whole year. Me and ‘The Aisies’ (that’s Daisy and Maisy) headed out on a lovely blue-sky day in March to move the herd. We wouldn’t be returning by the same path, so Cam kindly dropped the morning feed at our destination (thanks, Cam!). We could see him from a distance, making his way to drop the bag. “He looks like a tick!” Daisy said. I then had to explain to her how perspective works and that things look smaller at a distance… Walking out without a heavy bag always nice. We found the herd at the crest of the hill, a few were up and picking through the snow to graze, but most were dozing in the sunshine. They were initially slow to get going, and split into two groups which can make things difficult, but having three herders is a luxury and made it much easier to keep the herd moving in the right direction. I led, the Aisies herded at the back, and we skirted around the slopes easily enough, until we hit some big snow patches and the reindeer started to pick up speed. Eventually, Emmental decided she knew exactly where we were going and passed us. The herd followed, and most of them rushed over the snow to gather ahead, where the feed was waiting. I waited for Daisy and Maisy to catch up and we enjoyed having the last few minutes of the walk to just enjoy the sunshine and chat.
A lot of our most memorable days on the free-range are the big adventures, when it’s difficult, and you feel exhausted but accomplished at the end of it, but I always love the calm mornings, when things are easy, the sun is out, and you have enough time to stop for a moment and appreciate the reindeer and the incredible place we live.

I think we all love heading out to look for reindeer in the morning when they are free ranging on the high slopes of Cairngorm. My most memorable walk out this year was with Cameron, just at the end of winter start of spring. Our biggest challenge was what to wear. The weather was sunny one minute and then full on winter blizzard… So a full set of winter waterproofs, gloves, hats, hoods and last minute went back for ski goggles! We had a long walk and luckily we spotted them just before the weather changed into a white out snow storm. Goggles on time.
We had several challenging stream crossings, the first one had a big snow drift over it and was very dodgy spring soft snow, so we went for a crossing area up stream, with a good helping hand from Cameron when I jumped over, so no wet boots for me. After locating the reindeer Cameron lead the way as our plan was to move the reindeer to an area easier for our visitors on the hill trip, it took 30 mins in white out condition. Just as we got near our Hill Trip spot, we saw a hill walker on the hill path who unfortunately had a very noisey dog and, two barks later the reindeer turned on their hoofs and headed back up the hill! Luckily the sun came out, blue sky and we caught up with the herd not too much higher and changed our visit location as the weather was now sunny. It was now a safe option for our visitors. Cameron and I had a good work out and I wish I had a step counter that day – it would have been miles.

March has been my first taste of the free-range season, and thus has been host to many small ‘firsts’ for me! First time leading free-range Hill Trips, first time seeing the girls out in the mountains (leading them off the road in December doesn’t count!), first time out with radios trying to bring the girls to a nice spot for the Hill Trip in the mornings…
My favourite memory from this season was also my most trying morning. Fiona and I hiked out in the morning, braving blue skies but 30+ mph winds (which is quite a lot when you’re carrying a lot of reindeer feed on your back!). The cows and calves were happily resting in a little gully when we came upon them, and they were very much not in the mood for moving on! I was the ‘sheep-dog’ at the back of the herd trying to encourage some rather stubborn lassies on from the nice patches of lichen they had found, all the while unsuccessfully dodging boggy sections of ground. After finding a safe way to cross the river, I gave a quick celebratory ‘Yes!’, before promptly falling into a bog on my next step…
All smiles pre bog fall…

Hope you enjoyed all our favourite moments from 2026, and here’s to free – range season 2027!
In this latest blog I would like to share some memories from my visit in October 2025. It was very exciting as the new reindeer exhibition was open to visitors with lots of interactive things, videos, information and photo displays. It is so brilliant. The visitors will learn lots of things about reindeer and the history of the herd.
Emm is back, and we’re so thrilled! Emm, Lotti, Amy, and Jig all posing for a team photo!
On my first morning, I walked the calves around Glenmore with EK and Cameron. The calves this year (born in spring 2025) are named after types of dances so I had a lot of fun learning all their names. We walked Ballet and Polka with 2 adult reindeer.
Emm and EK walking Ballet and Polka during calf training.
We were getting them used to everyday things like people, traffic, being led and being handled. Afterwards, Cameron showed me his shed he had built for the reindeer poo bags so they don’t get wet and it is named the poo shed, and it is really good.
There were some new things in the Paddocks. The Santa’s bothy was being built by Alex and Cameron, and they were hoping it would be ready for Christmas. There was also an extended area for the reindeer in their daytime paddock area in the trees.
Santa’s Bothy under construction!
Jimmy the bull, who had been over on Silvermount in the hill enclosure with his group of girls, had finished his job with them so one morning Lotti, Ben and Cameron led him off the hill as he was going to go back to Tilly’s farm. We were also taking Gazelle off the hill to go back to the farm that morning too.

I led Gazelle off the hill to Brenda (the truck we transport reindeer in). Ruth and I went to find Vienna one of Iskrem’s girls as they had been moved into a different part of the hill enclosure and she had become separated from them. Iskrem is a very calm bull. We found Vienna and we had to herd her up the hill, as she didn’t want to be caught, to join Iskrem and his girls. Then we moved them as a group to a different part of the hill enclosure. We were very lucky that day as we saw 6 Black Grouse lekking.
Our hill enclsoure isn’t just home to reindeer.
The day after, I went with Kate, Ruth and Daisy back to Silvermount in the hill enclosure so we could move Jimmy’s girls to where they were meant to be next. Nuii and Fab were missing so Kate went to look for them. We let a few of them out to be with the main herd in the east enclosure in the hill enclosure and I helped Daisy and Ruth take 5 reindeer across the hill enclosure from Silvermount to a different part of the hill enclosure, as they were going to go out onto the free-range soon. I led Orinoco and Suebi. Meanwhile Kate had found Nuii and Fab and brought them back to join the group.

One day, the free-ranging reindeer were put in a part of the hill enclosure for a few hours so Amy could take Alba off the free-range, who needed to come into the enclosure for a short while.
Meanwhile Kate had gone to find 4 missing reindeer in the hill enclosure as they hadn’t turned up for breakfast or for the 2 Hill Trips and had been missing for the day. They were Pinto and her calf Quickstep and Borlotti and her calf Morris. Morris is such lovely natured and laid-back calf and is pure white meaning he is leucistic. Like some leucistic animals, Morris is deaf.

I helped Amy put the free-range reindeer back out. We took them to the top ridge on the free range, Amy led and I was at the back. Then we went to help Kate who had found the 4 reindeer on Silvermount in the hill enclosure. Pinto had found a bag of handfeed and was eating out of the bag when Kate found them. We led Pinto and Borlotti on halters and their calves followed and I helped Amy herd at the back. We led them across the hill enclosure and took them to the shed to check them out and take their temperatures as reindeer being away from the herd might mean they are ill. Whilst out leading them we were lucky enough to see a mountain hare.

One morning, the reindeer were slow coming down for breakfast in the hill enclosure. Some of the herd were with us and the rest were on Silvermount. As I helped Ruth call them down, Andi went up and herded them down from the top. We were then able to get them in position for the later Hill Trip.

Unfortunately on our way back down at the end of the day Brenda broke down near the Sugar Bowl car park. The next day, she was towed away to be fixed, a sad sight!
Stay tuned for part two of Emm’s visit in October!
Time for another installment of our – rather sporadic – memorable reindeer series. This time it is Porjus’ turn for stardom!
What a handsome chap!
Back in 2004, we imported a batch of male reindeer, mostly calves and yearlings, from Sweden in order to bring in new bloodlines, and one of these yearlings was Porjus. He was named after a settlement up inside the Arctic circle in northern Sweden just north of the town of Jokkmokk, where our founder Mikel Utsi was from. His name was pronounced ‘porr-e-us’, though we frequently referred to him as ‘Gorgeous Porjus’, sounding the ‘j’ so the words rhymed!
Porjus, at the farm not long after he arrived from Sweden. He’s around 1 and 3/4 years old here.
By the time I started here in late 2007, Porjus was an adult and had just been used as a breeding bull in his second rut, going on to breed during the next three ruts too, his last crop of calves born in 2011. His genetics remain in the herd today, most prominently through the descendants of his daughter Chelsea (who include the lovely Winnie, Zap, Diamond – and somewhat less lovely Pumpkin (a reindeer with a serious attitude issue!)) and daughter Jenga, whose son is Jelly. Whilst Porjus fathered lots of offspring over the years, not every calf survives long term, but some of his better known male offspring were Gnu, Topi, Horse, Origami and Svalbard, though these lads didn’t follow in dad’s hoofprints and breed themselves.

Porjus was a big, bulky reindeer, the ‘normal’ (average) colour for a reindeer, but with a distinctive paler forehead. Throughout each summer he always got incredibly fat – there was never any issue with his appetite – so much so we once tried to put him on a diet briefly (with hopeless results), but it never really mattered as bulls lose a lot of weight during the rutting season. A fat bull at the start of the rut is one that will go into winter in at least ok condition, as opposed to being underweight by the time the rut is over and winter arrives.
Fast asleep – saving his energy for the upcoming rut. Look at that belly!
Looking at our database, Porjus’ entry includes notes saying ‘A friendly boy’ and ‘well behaved during the rut’, and I certainly never remember being particularly wary around him during the autumn, though obviously we always give any bull a lot of respect at this time. Grandson, Jelly, would have done well to have considered Grandpa Porjus’ gentlemanly tendencies though – we planned to breed from him (Jelly) in 2023 and by less than halfway through the rut had changed our minds and castrated him instead!
Porjus’ grandson Jelly, looking like butter wouldn’t melt…
It is pretty unusual for a mature breeding bull to die in early autumn as they are in robust health ahead of the rut. However, Porjus did just that, dying extremely suddenly in September 2011 from an unknown cause (most probably tick-related), much to our dismay. However, whilst he left his mark in the form of his genetics in the last 20 years’ worth of reindeer born into our herd, he’s left another legacy too.
His is the incredible huge head in our Exhibition, gazing serenely over the thousands of people that come through our doors every year. Early autumn is the time of year reindeer look at their absolute best, with fresh thick winter coats and full grown antlers stripped of their velvet skin, so we therefore took the opportunity to have his head taxidermied. The only other taxidermied bull head we have hangs in Tilly’s house, having been brought from Sweden by Mr Utsi back in the 50s. For the last 14 years he and Porjus have gazed at each other across the room, but Porjus is so beautiful it would have been a waste for him to remain at the farm with hardly anyone seeing him.
So Porjus has found his rightful place back here at the Reindeer Centre – he was always a handsome lad during his lifetime, and now he is an awe-inspiring sight with his majestic look and his enormous antlers. I’m glad I knew him, and I’m glad to be able to admire him every time I come to work still.
A wonderful past blog written by herder Hen detailing how the species Rangifer tarandus (more commonly known as reindeer) is broken down into seven different subspecies, got me thinking that I didn’t know too much about these differences. What adaptations did each subspecies have to equip them for their differing environments? I decided to start my research with the Svalbard reindeer – the smallest of all the reindeer and only found within the islands of Svalbard.
Svalbard reindeer.
It is estimated that Svalbard reindeer became isolated from other populations of reindeer around 10,000 years ago when the vast ice sheet covering the Barents Sea melted as the earth warmed after the last ice age. Svalbard then became cut off from mainland Europe, effectively trapping any land mammals.

So, what happened to them 10,000 years ago to equip them with living on an open, isolated, arctic tundra landscape? Unlike other subspecies of reindeer, the Svalbard population dropped its need to migrate, only needing to cover short distances on a regular basis, remaining on mountain ridges and plateaus – continuously exposed to the elements. They also lacked forests for cover and fed primarily on short-growing lichens and vegetation.
The home of the Svalbard reindeer – open plains and Arctic mountains.
Apart from the occasional polar bear… the Svalbard reindeer also doesn’t have the worries that other subspecies have regarding predators. Due to these changes in their food chain and environment, the Svalbard reindeer evolved to have far shorter legs than the other subspecies. They could still reach a maximum speed of 60 to 80km/h but didn’t require the longer legs of other reindeer – so to conserve body heat, their legs became shorter.
Body heat is lost through a reindeer’s legs due to less fat and blood vessels near to the surface of the skin, so if you don’t need to migrate – grow shorter legs and stay warm!Svalbard reindeer running, perfectly displaying how disproportionate their bodies are to their small heads and legs.

Another unique adaptation to the Svalbard reindeer is their difference in circadian rhythm to other subspecies of reindeer. Svalbard has an extremely reduced day length in winter months. There are between 100 to 150 days per year during which there is no light and the sun does not rise above the horizon. Research has concluded that the Svalbard reindeer has a mutation in a gene associated with maintaining circadian rhythm, allowing their bodies to cope with lack of sunlight (vitamin D etc.). Another change in the genetic make up of this subspecies in comparison to the others, is a change in the genes associated with eye/ optic nerve development – allowing their eyes to adapt to winter conditions.
Svalbard reindeer have dark eyes, that like other subspecies are able to see into the shorter end of the light spectrum. This allows them to use UV light during twilight periods of the year to see their general surroundings – identifying food sources, other forms of life, etc.
Their diet is very similar to other subspecies of reindeer, feeding on low growing vegetation found along ridges, plateaus and mountain slopes. Feeding to excess on healthy vegetation during summer and then relying on fat reserves and limited grazing during winter when vegetation is limited, but lichen can be found in abundance. The Svalbard population is more of a solitary subspecies than the typical social herd structure of other populations of reindeer. They are often only found in groups of three to five and so over grazing is not as much of a concern in a smaller region, such as Svalbard. However, despite this, starvation is the most common cause of death due to worn teeth grazing on sparse vegetation growing amongst rocky landscapes, or from food frozen into ice pastures.

Despite their challenges and differences, one thing is for sure… the Svalbard reindeer are one darn cute animal!
Pocket-sized reindeer! Trying to think of something professional to say here, but all I can think is… STOP IT!
Okay, no more cute photos! I’ll leave it there until next time when we look at the cool adaptions of another subspecies of the Rangifer tarandus.
“Lichen, any of about 15,000 species of plant-like organisms that consist of a symbiotic association of algae (usually green) or cyanobacteria and fungi (mostly ascomycetes and basidiomycetes)” (Britannica, 2025). Now that’s a lot of big words and what do they actually mean? What really is a ‘symbiotic association of algae’? And why is lichen so important for reindeer?

Let’s look at the bigger picture to start. Cast your minds to the vast open landscape that makes up a subarctic tundra ecosystem. Excitingly enough, we can talk about our very own Cairngorm mountains for this, as our reindeer live in the only ecosystem of its kind in the UK.
The Cairngorm reindeer free roaming in the mountains.
A subarctic tundra ecosystem falls south of the Arctic Circle line and includes treeless habitats of permafrost and generally short flora growing seasons due to harsh weather and low temperatures. It can include fragmented plant growth, like rocky mountainous peaks with scatterings of low growing vegetation including mosses, grasses, dwarfed shrubs, and lichens.
These harsh conditions mean that lichen do not have to compete for space or light with other forms of vegetation, enabling the lichen to grow in blankets across mountain plateaus. Due to their unique differences to other plant life, they are also able to grow on exposed rocks and as part of biological soil crusts. These soil crusts are found in cold and dry areas and make up the majority of all living ground cover in these almost uninhabitable places. The crusts are made of living material that sit on the top few millimetres of ground, meaning larger plants are unable to root and grow due to the ground conditions.
An example of biological soil crust.
So that brings us back to our opening question, what is a symbiotic association of algae? What is lichen? From what we understand of lichen, it is a community of living organisms from both the fungi and the algae family. The fungi provide the water and minerals, as well as giving the lichen its structure, and the algae provides the food in the relationship, through photosynthesis. This happy partnership allows the lichen to grow and cope with harsh conditions that a normal single organism may not be able to thrive in.
The perfect partnership.
Now let’s add the reindeer into the mix! Reindeer rely heavily on lichen, consuming so much that it can make up to 70% of their annual food intake. This is because those harsh landscapes we spoke about earlier have very little choice available for the reindeer, but they can always rely on the lichen to grow all year round. Reindeer even have specialised gut floras to be able to properly digest the carbohydrates lichen contains.

Maybe it’s not that it tastes good then, maybe it’s because they have little other choice?…
But if you asked our reindeer, they would tell you it’s the best thing on the menu!
Delicious!Dixie enjoying a mouthful of lichen. Macchiato with a lovely big patch.Mocha with a bit of lichen hanging from her bottom lip!
With autumn being the season that the calves return to the hill enclosure, along with their mums, it’s always exciting to see them and to start to get to know them as characters. Having spent all summer with males only in the enclosure, it’s suddenly a bit overwhelming to have a sea of ‘new’ reindeer to get to know once again! The calves are the hardest to learn who is who.
Last time we saw them properly, in late spring, they were tiny and heading out to free-range in their calf coats, which are quite different in colouration to an adult reindeer’s coat. By autumn they’ve moulted, grown their new winter coat, and are many times bigger – i.e. they look COMPLETELY different! Other than very obvious colour variation and face markings, their wee antlers are the easiest way to tell them apart. The photo below shows Macchiato at 4 months old, looking about as generic as is possible for a reindeer calf – very average size and shape antlers, along with being very much the ‘normal’ body colour. Difficult to tell one from t’other, looking like this!
Macchiato, aged 4 months
So I thought I’d show some of the antler shapes of calves over the years in this blog. The memorable ones tend to be the biggest ones, of which the outright winner – by a country mile – is Gandalf. However, he was born in Sweden, and many of the Swedish calves we’ve imported over the years (to increase our genetic diversity within the herd) have had very big antlers so maybe he should be disqualified my list…
But here’s a photo of Gandalf anyway. Compare those antlers to Macchiato’s in the photo above!
So… my winner for sheer height of antler is Jester, who definitely looked a bit out of proportion as a calf. He’s gone on to grow enormous adult antlers too, though tending towards wider rather than tall.
Jester.
Some calves have really complex antlers – not quite as tall as Jester’s but more elaborate with several points on each. Examples include:
Murray, born in 2012. Look at that headgear!Christie (antlers still in velvet here) – exceptional as she is female. As an adult she’s gone on to have very big antlers each year, a family trait inherited from mum Caddis and granny Haze.Cream – these calf antlers always reminded me of water divining rods!
Duke gets a bonus point for having a forward-pointing tine at the base of one of his calf antlers – perfectly normal in an adult reindeer, but rare in a calf.
Duke.
Whilst not the biggest calf antlers ever, Fez wins my ‘prettiest’ antlers award. Small and perfectly formed, with several points top and bottom. Beautiful!
Beautiful in antler – and face!
But sometimes, it all goes wrong. Calf antlers, being thinner than adult antlers, are easily broken, especially as adult reindeer show no love whatsoever for anyone else’s offspring other than their own, and are all too willing to whack a calf on the head with a hoof should they get in their way. This results in antlers breaking, and this happens whilst the antler is still growing, they will sometimes fuse at the break and the calf is left with a flopped-over broken point.
One of this year’s calves, Lochi, with the classic ‘been-walloped-on-the-head-by-a-hoof’ look.
If this happens early enough in the season, the antler will, once the break is fused and healed, start to grow upright once again from the break. Here’s Fava below, who had managed to break his right hand antler not once but twice, resulting in two downward pointing bits. His antler shows a centimetre of new, upward growth from the break – and then he ran out of time to grow any more!
Fava.Hopscotch.
Antlers broken right at the base can cause a problem with obscuring vision, poor Hopscotch here had to have this disaster (above) sawn off once it had lost all feeling in the autumn, so she could see where she was going!
And sometimes, it all just goes terribly, terribly wrong…
Poor Heinz! Two broken antlers, bound in place to keep them as still as possible, waiting for the vet to arrive.Holy Moley.
Holy Moley’s broken antler resulted in a shaved head after the vet had to remove the broken bit right at the base to prevent further damage. Some of you might remember watching her story on our Channel 4 documentary in 2020!
