When sorting through antlers recently and selling various sets, I realised that female reindeer Marple has been kind enough to give us hers for the last three years in a row, which is very unusual. By ‘give’, I mean that she cast them in the hill enclosure, giving us a higher chance of coming across them as compared to losing them outside the fenced area – where they are rarely found. How kind of her!
Marple with a very characteristic expression!
Although I don’t have any of the sets here anymore, I do retain photos of each set sold for my records, so this seems like a good opportunity to talk about similarities from year to year for antler growth for a particular reindeer.
Marple grows what I would classify as a very ‘typical’ set of antlers for a reindeer – average size for cow antlers, with a ‘blade’ at the base on one side (the tine which comes down towards the nose), front points – originating a little higher – pointing forwards somewhat like a stag beetle’s pincers, and then upright shafts which have multiple tines coming off them.
One of my most regular questions on the Hill Trip is whether or not reindeer grow the same shape of antlers each year. The answer is emphatically a yes, though by no means identical. The photos below show Marple’s antlers from age 3, 4 and 5, and you can see they have the same basic layout from year to year.
Antlers age 3Antlers age 4Antlers age 5
But antlers vary hugely, so here’s a composite photo of a ‘pair’ of antlers from two very different bull reindeer, by way of illustrating the differences between individuals whilst still showing the basic layout of the blade, front points and upright sections.
Antlers from bulls Bandy and Gandi – Bandy’s is extremely simple up at the top and Gandi’s far more elaborate (but missing the blade at the base as it was on the other antler of the pair, of which I don’t have a photo).
So what affects how antlers vary from reindeer to reindeer? The answer is primarily genetics. Antler growth is genetically inherited, so a reindeer with parents with rather simple antler growth is unlikely to grow anything too fancy, and vice versa. One of the reasons that our big lad Sherlock grows such enormous antlers is that genes for excellent, huge antler growth run in his family line; both his mum Caddis and dad Atlantic grew huge antlers themselves – Caddis exceptionally so for a female. Marple grows very similar antlers to her mum Ochil, as seen below:
Marple’s mum Ochil (with Marple as a newborn calf!) showing the similarity of her antlers to Marple’s (inset).
Environmental factors affect antler growth too. Having enough energy to grow good headgear is dependent on being in good enough condition, so the grazing abundance and quality is important, which is obviously heavily influenced by the weather. Really hot weather can mean reindeer spend more time lying on snow patches to keep cool, or jogging about to try and evade flies that are buzzing around them, leading to less available grazing time. As I write it’s early July and 9 degrees and raining outside. I’m still having to wear a thermal top under my normal layers and I’m generally pretty grumpy about that fact, but the reindeer are loving life – grazing constantly with no flies around them at all. Every cloud…
Finally, a big part of antler growth is to do with body condition. This can be linked to environmental factors as we’ve just talked about, but other things also affect it, for example illness. A reindeer fighting an illness concentrates their energy on preserving body condition, and antler growth pauses as a result. It will start again if and when the reindeer recovers, but the damage is done and the antlers end up smaller, or slightly malformed, compared to a ‘normal’ year.
Merida with lovely antlers and no calf, and the following year with a much poorer set, but a calf at foot
Female reindeer raising a calf need lots of energy to produce milk, so their antlers often suffer over the summer months, being smaller and often rather wonky. Some reindeer are prime candidates for this – looking at you, Merida! – whilst Marple actually doesn’t struggle too much. At 6 years old she’s in the prime of her life and has energy to spare, so both a big calf and decent antlers in the same season are achievable. However, the difference is still noticeable to some extent: here are those three photos again – the first pair grown when Marple was three, with no calf at foot, and the second two grown in the subsequent years but both times with a calf at foot. The first pair are slightly taller and perhaps a little more elegant, whilst the others are a touch shorter and a bit ‘squatter’ (although a little chunkier as Marple matured).
I thought I’d write a bit about some of our biggest reindeer pet peeves this week – and undeniably, there are quite a few… Pet peeves 1-4 are tongue-in-cheek, so don’t take offence if you’ve made one of these slips in the past – no doubt some of us did too before becoming reindeer herders! But peeves 5 and 6 are serious, and a cause us a constant headache – please don’t be *that* visitor…
Number 1: ‘Reindeers’
The biggest pet peeve of all is most definitely… ‘reindeers’. The plural of reindeer is reindeer, with no ‘s’, and whilst I’ve never heard anyone say ‘sheeps’, ‘reindeers’ is a very common mistake. It’s only a little thing and it’s hardly going to change the world if you say it right or say it wrong, but it’s just something that grates so much. You will see a tiny shudder of horror pass over any one of us if you see us talking to someone who uses the word ‘reindeers’. Not to mention my roar of disgust earlier this year to open our local paper – who really should know better – to find that they had used ‘reindeers’ (in very large font) in the title of their article about us. Face plant.
One REINDEER……multiple REINDEER.
Number 2: ‘Horns’
I guess there’s really no reason for people to know or understand the difference between antlers or horns, unless they have background knowledge in biology. But still, when reindeer’s antlers are referred to as horns, it’s something that makes my eye twitch – the word just sounds so wrong. To educate anyone that doesn’t know (every day’s a school day), animals that grow horns, such as cows, sheep and antelope, only grow one set in their lifetime and the horn is made of keratin, the protein that your hair and fingernails are made from. In contrast, antlers are made of bone and are grown by members of the deer family only, and they are grown annually, falling off each year. Technically therefore, they are classed as ‘deciduous’ – not a word normally used other than in relation to trees.

Number 3: Reindeer imagery at Christmas
Oh god… where to start? I think 99% of ‘reindeer’ imagery used on Christmas cards, decorations etc, are not actually reindeer at all.
Where to start?! Santa’s sleigh pulled by… fluffy white Wapiti? They certainly ain’t no reindeer….Don’t get me started on the fact that reindeer and penguins are found in different hemispheres. They live at opposite ends of the planet, and always have (other than the introduced population of reindeer on South Georgia who lived there for around 100 years before being eradicated about 10 years back, but I doubt that this Christmas card designer was aiming to represent the fauna of a South Atlantic island). In fact, don’t get me started on the (lack of) connection between penguins and Christmas at all…Granted, it is a reindeer. But with a set of… red deer antlers on it’s head. Backwards on it’s head. I don’t even know where to go with this. The worst thing is it is an advert for a reindeer parade where the providers of the reindeer were – us. We send the organisers of all events we take part in a link to a load of beautiful press photos for them to use for promotion purposes, which, funnily enough, does not include the abomination above.
Number 4: Carrots
If you happen to have a child who still believes in Father Christmas and are reading this aloud to them… stop now. I don’t want to be responsible for breaking hearts. If you’re an adult however, and think that reindeer love to chow down on a carrot or two – prepare yourself for a shock. Reindeer DO NOT eat carrots. It is a myth. I’m sorry, but there it is.
Santa will eat the mince pie and he’ll no doubt enjoy the dram, but if the carrot vanishes overnight, it’s not Rudolph. Perhaps Santa’s just making sure he can see in the dark? Photo: Scotsman website
Once again, let’s shoe-horn in some education. Reindeer are ruminants, meaning they have four stomachs, like cows and sheep. They have similar dentition too, having tiny teeth at the front of the bottom jaw, and a flat, bony palate at the front of the top jaw (plus molars top and bottom at the back). This means they nip away at the vegetation with the small front teeth, swallow it into the first stomach – the ‘rumen’ – and then bring it back up to chew again with the molars before it progresses through all four stomachs. Tiny front teeth can’t easily much up a carrot, and nor do carrots grow naturally anywhere that reindeer live, so they do not form part of their diet. I am actually aware of reindeer in permanent captivity in some places being fed carrots – but any reindeer that actually eats, or tries to eat, carrots is doing so out of desperation because they are not being fed a sufficient diet.
A reindeer’s teeth. Not designed for eating carrots!
Working here taught me to quickly work out when to lie to people – if an adult brings us carrots for the reindeer then I will tell them the truth. If a small child gives me a carrot at a Christmas event, to give to the reindeer? Then perhaps they do eat carrots after all, but only on Christmas Eve. Not right now. Makes ‘em fly, you see.
Number 5: Visitors who don’t read any information when booking their tickets
I hesitated to include these last two pet peeves… but my fingers have just kept typing, and realistically, they are the ones that actually cause us herders problems, rather than just annoy us. Visiting the reindeer here at the Centre is wonderful, and we do our utmost to make sure everyone has a lovely time. But you need to know what you are getting yourself in for, and you need to know what clothing and footwear you need to bring, in order to visit the reindeer safely and with maximum enjoyment. The people who book tickets, tick all the required boxes to say they will have the right footwear etc; they understand they need to use their own car; they realise they have to walk to the reindeer, etc etc etc – and then turn up having not actually read ANY of this info, make us want to cry. Hill Trips change throughout the year, starting from different car-parks and using different routes, so having visited before doesn’t mean you know what to expect.
We have all been shouted at by angry people over the years when it’s entirely their fault and not ours that they’ve (delete as appropriate) missed the Trip/have the wrong footwear/are completely unsuitably prepared. Please. Just. Read. It. All. First. Please.
Number 6: ‘That’s not actually waterproof…‘
Peeve number 6 is linked to number 5. We ask visitors to bring a waterproof jacket with them for the Hill Trip at all times, and in the winter season (Oct – Apr) we ask them to bring waterproof over-trousers too. Obviously we can’t predict the weather and whilst waterproofs might not be needed on the day, at times they really are essential, and it is for people’s own safety that we have to insist they are wearing full waterproof clothing. Hypothermia becomes a risk quickly in winter conditions, and much more so if someone is wet to their skin.
Please understand we don’t want to turn people away, nor force them to purchase waterproofs they may not wear again, but as a company we also REALLY don’t want to be responsible for cases of hypothermia either. Safety in the mountain environment has to be foremost so you MUST come prepared for the worst weather, and just be grateful if you are lucky to get nice weather on the day. It’s also a matter of your own enjoyment – we want you to have the best time possible and you have more chance of doing so if you are not soaked through and frozen.

However, it seems the problem is deep-rooted in that a surprisingly large percentage of people seem to have no understanding as to what the word ‘waterproof’ actually means. It’s really not hard – it means… ‘waterproof’. Water can’t get through. Wet one side, dry the other. Not ‘water-resistant’, not ‘shower-proof’ – ‘WATERPROOF’. No, your ‘hiking trousers’ aren’t waterproof. Nope, nor your puffer jacket. Nor your ‘yoga pants’ (I kid you not – I have had this conversation with someone in our shop).
Cameron suitably dressed for the mountains in winter – hiking boots, waterproof jacket and waterproof over-trousers. Lots of layers underneath too. And look how warm and happy he is!
We’re rather at a loss as to how to get it across to people? We’ve tried everything. I’ve resorted lately to literally asking people if they would remain dry if I chucked a bucket of water at them. No? Then your clothes ARE NOT WATERPROOF.
As I write this today (in late March) 6 of the 26 people booked on the Hill Trip had to buy waterproof trousers in our shop (we have some ’emergency’ pairs for sale) before we would let them take part – despite knowing perfectly well upon booking that they needed to bring them, ticking a box to declare that they had them, and being reminded in three separate emails. March is not necessarily spring here – today it was full on blizzard conditions on the hill.
I can go into all sorts of other pet peeves, but I’m starting to feel a bit frazzled just thinking about it all, and I notice my use of capitals is increasing throughout this blog as I feel more and more shouty, so it’s probably time to stop here.
Despite spending the last 40+ years devoting my life to the Cairngorm Reindeer I am still fascinated by the annual cycle of reindeer growing their new velvet antlers, then stripping the velvet to reveal hard bony antlers and finally casting their antlers and growing a new set next year.
It is an amazing process, hugely demanding on their resources, but very beneficial to the individual whether they are males competing for females in the rut or females and young males competing for food in the winter.
The older mature males grow the most impressive antlers and for them the process of growing their new velvet antlers begins before the end of the winter and continues until they strip the velvet from the antlers around the middle of August, in preparation for the rutting season. The bigger the antlers the more likely they are to ‘win’ a fight and so claim a harem of females, so big antlers are important.

One of our main breeding bulls Sherlock showed all the signs of growing a pretty big set of antlers last year and by the autumn he didn’t disappoint us. Luckily for us he is a real gentleman among reindeer and although he sported these great weapons on his head, he was never aggressive towards us and we could still safely go in beside him and his breeding females on a daily basis to feed and check them all.
Sherlock – 29th of August 2023 – stripping the velvet.Sherlock in the rut with Bordeaux in front of him on the 2nd of October 2023.
But their glory doesn’t last long and having spent 5 ½ months growing their antlers the breeding males are the first to cast their antlers at the end of the rut and before the winter sets in. So only about 10-12 weeks of glory with big hard antlers to fight with!
Spartan, who is a couple of years older than Sherlock was first to cast his antlers in the middle of November so I knew it wouldn’t be long before Sherlock was antlerless too. Two weeks later and off came one of Sherlock’s antlers making him very lopsided! Then a couple more days and the other one had fallen.
So now we are in 2024 and Sherlock, who was so dominant in the autumn, has been at the bottom of the pecking order over the winter.

Over the years I’ve established myself as ‘chief of antler sales’ here at the Cairngorm Reindeer Centre. As with most reindeer related things, it’s not really a job that is straight-forward but one that has evolved with time, and I’ve tweaked and tweaked each year until it is as workable as possible. But – in usual fashion – the devil is in the details, much of which are in my head and memory and it’s therefore not a job that I delegate to anyone else.
The dream set of antlers everyone wants… (thanks Spartan).
We’ve always sold antlers from the reindeer herd. But is it as easy as 150 reindeer equals 300 antlers per year to sell? Of course it isn’t…
Firstly, we only find around 30-40% (at a rough estimate) of the antlers each year. This is because the reindeer roam on a huge area of rough, upland land, and the time of year when most antlers are shed – January to April – is exactly the time that almost the entire herd are roaming completely freely and are not enclosed at all. The proverbial needle in the haystack. (In fact sometimes finding the herd itself can be a needle/haystack situation, let alone their cast antlers!).
So many antlers, so few of them found.
Secondly, whilst around half of our herd are males, we tend to castrate them at around three years old. This means the bone of their antlers doesn’t calcify to the same extent, and they will usually break their antlers off in pieces as a result. So instead of a nice, clean antler, we get broken sections of – to be quite honest – often rather manky antler, still partly covered with the velvet skin that covered it whilst it grew. Smaller pieces disappear into deep vegetation – never to be seen again – far more easily than a whole antler.
A classic bit of antler from a castrated male. This one’s from Frost – the top third of his right hand antler, still with remaining skin and a little velvet hair. But it’s still a bit of Frost none-the-less, regardless of it’s appearance.Classic antlers from a castrate male around February time- the upright sections have broken off and only the points at the base remain, still with the remnants of the velvet skin and hair. Not particularly glamorous, eh Caribou?!
Once castrated, males also tend to grow relatively smaller antlers than they did as a bull. So we really only get two or three big, mature bull sets of antlers each year. But some of these we keep – for example we have almost all of Sherlock’s antlers, and most of Crann’s. Crann holds the record for the biggest antlers ever in the herd, and as such we’ll never sell them as they are of great nostalgic value to us, even though Crann himself is long gone.

Antler selling starts in January each year. The mature bulls have dropped their antlers in November/December, and some of our immature bulls then have their antlers cut off in December before they are let out to their winter grazing up on the mountains. This is done for the safety of hill-walkers – a testosterone-charged ‘teenage’ bull could really inflict damage. It’s done long after the feeling in the antler has gone, so causes zero pain.

From (usually) around February or March onwards the cows start dropping their antlers, but for me life gets very busy in the spring with the calving season, followed by writing/editing the June newsletter, so it’s often well into the summer before I pick up the antler list once again.
So… here’s some info for those of you now imagining a nice set of antlers adorning your wall.
Firstly, I give members of our reindeer adoption scheme priority for purchasing antlers over ‘unconnected’ members of the public. I feel it’s a privilege someone who supports our business should get. My method for this is to have a waiting list for adopters to add their name for dibs on ‘their’ reindeer’s antlers, which I work my way through gradually as and when I have something suitable. Should you want to add yourself to this list, drop me an email through the contact form on the website FAO Hen (please don’t just comment on the blog/social media – email means I can keep everything together, and gives better chance of a reply one day from me actually reaching you, rather than disappearing into spam).
If you’ve asked to be on the waiting list in the past, no need to get in touch again – you’ll still be there. Well you will as long as your adoption is still current. I’m afraid that I always double-check someone is still an adopter before emailing them, and you’re scratched off the list if your adoption has lapsed. My list, my rules.
If I have no-one on the waiting list for a particular reindeer’s antler(s), then I will send a letter to all of their (UK based) adopters in one go – and it’s first come, first served. Miss out, and you go on the waiting list. This does mean sometime multiple people are all waiting for the same reindeer to shed his/her antlers – which we might never find from year to year anyway. I’m well aware some poor souls have been languishing on the waiting list for years… sorry.
If you aren’t an adopter of a reindeer and are reading this in despair, wondering whether there’s ever a chance of you getting anything, then all is not lost. Email me anyway, and I have a password-protected webpage with any available antlers on that I can give you details of, and on which you can sign up for occasional email alerts when new ones become available (if I get my arse in gear, this is still only two or three times a year, so don’t worry about me flooding your inbox. (Also, I hate Mailchimp – it’s totally user-unfriendly)). I have separate webpages for single antlers and for pairs, and usually have a much better range of single antlers, since finding both sides of a pair is rarer in the first place.
A small, single antler can be very beautiful – size doesn’t always matter 😉
Final info:
Yes, they do cost a lot. The biggest sets we ever get to sell are in the region of (at time of writing in 2024) £300. The single antler in the photo above was about £60. I guess other places with reindeer in the UK maybe also sell their antlers, but I’ve never actually heard of them doing so. I do my best to price antlers fairly though – every single one is utterly unique and in some way it is a snapshot of that reindeer at that particular point of their life. I’m sure I could push up the prices hugely and they would still sell eventually, but that isn’t the point. It’s a balancing act to try and get it right.
For adopters, if you perhaps can’t afford the antler(s) you been contacted about, it’s still worth going on the waiting list. I might have a glorious £200 set of beautiful antlers one year from your reindeer, and a single broken-off – much cheaper – half antler the next year. But hey, it’s still a piece of antler that your reindeer actually grew, and really it means just as much.
Conversely, you miss out on something small that you had your heart set on. But hey presto you might then be first in line for the potentially much more impressive effort from your reindeer next year. It’s all utterly unpredictable and there’s definitely an element of luck involved.
I can’t post abroad, sorry.
If you can collect your antler(s) rather than me having to package and post them, a) it’s cheaper and b) I love you.
Postage nightmare.
If you receive an ‘antler letter’ through the post – read it properly! I always do my best to describe the antler fully before you phone up to buy it – but have never forgotten the lovely couple who arrived to pick up a set of antlers from their adopted reindeer years ago. The bloke was a bit worried about fitting them in the car. The antlers were about 30cm tall.
Antlers come in all sizes but all shapes too. Forget that classic set of ‘perfect’ shapely reindeer antlers you’ve got in your mind’s eye – they probably aren’t going to look like that… If I’m emailing you directly I’ll attach a photo, and if I’ve sent you a letter, you can ask to see a photo before you decide.
Tall and thin……or short and wide?
As mentioned before, we keep some of the biggest bull antlers. Herders also usually have first dibs on their favourite reindeer’s antlers (I’ll add that (depending on the size of antler) we do usually still have to pay something them!), so there are certain reindeer in the herd whose antlers will come up for sale very rarely, if ever. Huge apologies, if you also adopt one of those reindeer… let’s mention no names.
I do also try to be fair to people – if I know you already have multiple antlers from a certain reindeer but are keen for more, I will usually try and give their other adopters a look in at some point.
And if you adopt Juniper, well don’t give up hope. Ferrari was also a ‘polled’ reindeer (one who doesn’t grow antlers at all) and suddenly sprouted one when she reached 9 years old, so all is not lost. But I wouldn’t get your hopes up too much.
Ferrari in her latter years. Just one antler! But what a nice antler, after 8 years of baldness.
And finally, I’m only human so bear with me as the old brain doesn’t get everything right every time. Apologies again to the lovely lady who I posted the entirely wrong set of antlers to a couple of years ago, and then had to go through a whole rigmarole of getting her to post them on to the correct new owner (Editor’s note: we did get permission to pass on the address first!), whilst I sorted out the right set for her. And years ago I died a little bit inside when I realised we’d sold the same antler to two separate people, and I was going to have to make a very awkward phone-call (although in my defence, it wasn’t actually me that forgot to mark that antler as ‘sold’ on the list). Oh, the horror.
As Ben and Fiona have explained in previous blogs (click here, and here to read), we had a busy December with events and parades up and down the country, as well as a busy Centre here in Glenmore with fully-booked Hill Trips and Christmas Fun paddock slots! Plus hundreds of adoption packs to make up and post out, alongside all the usual office antics.
For this week’s blog, I’ve collated a series of photographs found on my phone during this particularly busy month to give a brief snapshot of what went on in the life of a reindeer herder. Turns out I don’t take many photographs whilst I’m sat in front of a computer answering emails so the photos are quite biased to all the fun times I’ve had out and about. Thankfully this makes for a much more enjoyable blog… lots of pictures of reindeer!

What superstars they are.
They’re the most distinctive feature of the reindeer, and the most incredible. Branching elegantly like the trees which the tundra so sorely misses, and renewing themselves each year, antlers demonstrate nature’s complexity and mystery in one. At this time of year the reindeer’s quickly growing antlers constantly amaze visitors and captivate my own imagination. It occurred to me recently that the cells in growing antlers and the cells used in the Covid-19 vaccine are both the same type of rare cell: undifferentiated stem cells! It might be interesting to join the dots between this.

Greater Antlers, Greater Chances…
Large antlers lead to a (sexually selective) advantage in males, and even in females too as those that are better able to defend areas of food in the winter are more likely to produce healthy offspring. A physical advantage in a single characteristic, leading to it’s selection is a process called directional selection. This means that over time, reindeer populations evolve very (VERY) gradually to have larger antlers.

However, large antlers come at a cost, requiring huge amounts of energy to grow in such a short space of time. Reindeer eat lichen, which is fairly low in nutrition and has a long digestive process, as well as other low lying plants, mosses and mushrooms found across sub-arctic areas. As even eating a lot of food won’t make up the energy, the animals shift calcium from parts of the skeleton which don’t carry a lot of weight (such as the ribs) in a process called cyclical reversible osteoporosis, which humans also go through during pregnancy. There are still more adjustments, as the reindeer’s neck and shoulder muscles need to swell in order to carry the bulky weight of the antlers, and movement becomes restrictive. It’s no wonder then that the rutting season becomes so taxing for large bulls that their life is typically shorter than that of a female. Taken to an extreme there is even a theory that the great Irish Elk, or Megalocerous, was partially driven to extinction due to the amount of energy it lost to it’s enormous antlers! I find it unlikely that this will happen to the reindeer but there’s no doubt that these huge organs take a lot for the reindeer to grow.
Although we know what pushes antlers to grow to such a huge size, it’s truly incredible when we begin to ask how. Antlers are the fastest growing organs in the animal kingdom, potentially growing around three inches a week (dependent on nutrition). This is mainly due to the quick regeneration of stem cells from which they are formed; the only type of cell in a body which can differentiate into any kind of tissue, such as bone, fat or skin. We have some of these cells in our bone marrow, as an important part of our bodily regeneration, and the quick formation of embryos is also due to them. Stem cells are also an important resource in therapies for degenerative diseases or to support the body following certain aggressive cancer treatments. Stem cells have even been used in the creation of several vaccines – including for Covid-19! This, combined with their versatility and potential in lab experiments makes stem cells an extremely valuable resource to medical research. It’s awesome to think that the same cells from which reindeer antlers are formed are what we use to treat life threatening diseases.
Finally, the antlers are not just useful to the reindeer, but also to the other animals in the wider ecosystem. Often when we find an antler which has been out on the hill for a while it will be worn thin and marked by the tooth marks of different animals. In the Paddocks we also see that mice and squirrels chew the antlers in the display area! This is because once they are dropped they are an open source of calcium which sometimes the reindeer, or other animals, (like your own pet dogs) will chew in order to reclaim the minerals. There have even been times that reindeer have chewed each other’s antlers while they’re still on their head!

Next spring I plan to photograph the same reindeer once a week from the time it’s antlers are small stumps until they’re fully grown as there really is an incredible difference. There’s so much which is unique and wonderful to say about antlers and I’m looking forward to writing still more about them!

P.S. What’s the difference between an antler and a horn?…… A horn makes a noise!
This week’s blog is written by long-term volunteer and reindeer adopter, Sharon. She got so fed up of us never having getting around to featuring Indigo in a ‘Memorable Reindeer’ blog that she decided to write one herself! Other blogs about well-loved reindeer of the past can be found by typing ‘memorable reindeer’ in to the search box to the right.
We started visiting the Cairngorm Reindeer Centre when our two boys, David and Mathew, were 9 and 6 years old in 1996. They have many memories of hand feeding the reindeer and Mathew particularly often recalls being knocked over by a reindeer when he was trying to get out of it’s way! How impatient was that he says?
In 2003 we had a particularly enjoyable and very snowy visit just before Christmas and my husband paid for an adoption of Indigo for my birthday.
Me and Indigo in December 2003
What a pretty girl Indigo was.
Indigo had followed me around on the Hill Trip and had numerous handfuls of feed from me. She constantly searched my hands and my pouch pocket for hand feed and I fell in love with her instantly. I always claim in reality she adopted me! She was such a friendly reindeer, particularly if you had hand-feed, a bit like my current adoptees – cheeky and greedy!
Regularly the owner of a bizarre set of antlers…
…swept back style…
…bonsai style…
We visited as many times as we could, usually at Easter or in December when we came up for two weeks in our caravan for Christmas and to ski at the Lecht which was always popular with our boys. The Christmas Eve torchlight procession through Aviemore was so magical with the reindeer leading. There was always plenty of snow around, not like the rain in more recent years!
Aviemore Christmas parade back in around 2012 or so. It was -12 degrees C during this parade, hence the grimace on Hen’s face – also shaking hands are possibly the reason why the photo is blurry!
In the summer of 2012 I received a letter from Hen asking if I wanted to buy one of Indigo’s antlers. I was on the phone to say yes before I had even read who had written the letter! As a very special treat my husband cut a piece of the antler off and made a pair of earrings for me out of it, another Indigo birthday present. I know now whenever I wear them she is still with me.
My antler – when still on Indigo’s head!
In February 2014 I received a letter from Andi saying that Indigo couldn’t be found and had probably died. I was distraught but continued to adopt. I now adopt Svalbard and Celt who are both very enthusiastic reindeer when it comes to hand feed and my husband adopts Olympic, who is a favourite with all adopters. My adoption certificates are kept neatly in a file with all correspondence from Reindeer House and we have even been to Finland to meet reindeer, although we haven’t found any as well cared for as the Cairngorm herd. So 24 years of visiting the reindeer, 18 years of adopting, 4 years of volunteering and my own ‘reindeer herd’ on the back seat of my car (soft toys only) my addiction continues. But then it is not the worst addiction in the world to have – is it?
When people think of reindeer, they inevitably picture them with a big set of antlers atop their furry heads. Unlike other deer species, this even applies to females, who are the only deer species to routinely grow a lovely pair of bony protrusions each year, in order to help them hold a high enough status within the herd to gain enough access to feed in harsh climates.

Only… some reindeer don’t grow antlers. The official term for this is “polled”. We’ve had a number of individuals over the history of our herd (and this is the case worldwide too) who, year after year, maintain the smooth top to their head, whilst reindeer all around them are tapping away to encourage the velvety growths which finally turn into hard bone at the end of each summer.
This is almost always seen just in females (cows), and when scientists have studied reindeer and caribou herds across the herd it seems that between 0.5 and 5% of cows can be expected to not grow antlers. Why would this be? Antlers are used as weapons when fighting for dominance within the herd – indeed a cow with large antlers is rarely challenged. So surely not having antlers is a disadvantage? On the surface, yes, but by not growing antlers a huge amount of energy is conserved every single year. In some habitats, like the thick forests that forest reindeer and woodland caribou live in, antlers can be a hindrance, and the smaller herd sizes perhaps mean there is less of a need to compete. Antlers are more important for a male in terms of breeding success, as a bull with just one or no antlers at all is unlikely to have the chance to breed.
Antlers are hugely important for breeding success for bulls – if you don’t have antlers you won’t win cows.
There seem to be two factors behind refusal to grow antlers. First, there is nutrition. A reindeer who is struggling to find enough food will prioritise body condition over antler size – an adult who is having an unexpected hard year will grow smaller antlers than usual. If this happens to a calf – for example one who is orphaned at a young age, they may not have any antler growth at all in their first year, or perhaps for longer. Our wee reindeer Diddly had a difficult start as her mum Flake didn’t have any milk, and whilst we bottle fed her, we couldn’t match the nutrition reindeer milk would have provided. Perhaps this was the reason she didn’t grow antlers?
Diddly by name, Diddly by nature, and never an antler on her head…
The other factor is genetics – as we trace all of the family history of the members of our herd, we can often trace lack of antlers back to an ancestor. It seems to be that the polled characteristic is a recessive one, often carried but only expressed if a calf inherits two copies of the gene. I was interested to find this note when looking back through old diaries from the early days of our herd:
So for Mr Utsi, who founded our herd, polled (antlerless) reindeer were a desirable animal, and I also feel that antlerless females tend to be strong characters – perhaps because they’ve had to hold their own in an antlered world?? As our reindeer have a pretty easy life and we supplement their grazing in winter with feed, any antlerless cows tend to be that way because of their genetics rather than a lack of nutrition, and perhaps with plenty of food available there is no huge detriment to their diet if they happen to be a little further down the pecking order.
Wonderful Arnish – lack of antlers never got in her way.
Arnish, one of the leaders of the herd when I started work as a herder, never grew an antler in her life, but was well respected among the other reindeer – if challenged she would simply use her front feet in place of antlers! She was also a successful mother, rearing Addax, Jaffa and Svalbard. Jaffa’s daughter Brimick only grew one antler. We also have one-antlered reindeer Dixie in the herd, who inherited this trait from grandmother Cherry.
Dixie, proud of her singular antler.
Ferrari didn’t grow antlers at all until she was nine, then surprised everyone by growing one antler annually (on the same side!) until the end of her days. Interestingly, she’s a direct descendant of polled cow Mitou (mentioned above). From her descendants, her grand-daughter Malawi is in the herd today and has been antlerless so far – she’s currently fifteen so I think she’ll probably not start now! Ferrari’s great-grandson Merrick was also the only male we’ve had yet who grew just one antler, after growing nothing as a calf.
Malawi – not an antler to be seen!
Merrick as a calf with no antlers. Definitely genetic rather than due to a lack of nutrition – he was one hefty calf!

And what about wee Bond, some of you who follow our stories closely may ask. As an orphaned calf, he grew no antlers at all (caused presumably by struggling to get enough nutrition), then last year as a yearling he tapped furiously away at his pedicles (where the antlers grow from) and managed about 1 inch of antler on one side (you had to peer pretty closely to see it!). You’ll have to wait to find out what happens this year…
Yearling Bond, not the most impressive of headgear…
Around mid March Fly, one of our mature female reindeer started to grow her antlers. March is pretty early but I suspect due to a warmer winter than we usually have and possibly the growth of vegetation starting earlier this has brought on an early antler growth in some reindeer. Fly has certainly grown some of the biggest antlers we have seen in female reindeer over the years, as well as producing some of our biggest calves so she’s certainly an asset to our herd and is now the grand age of 12… yet still looking amazing!
Here is a sequence of photos over 9 weeks showing how incredibly fast Fly’s antlers were growing.
Her antlers grew a good 2 inches between week one and two.
About three inches between weeks two and three.
Between weeks three and four the antler started to show its first split into another point on her right antler.
Then between weeks four and five her left antler didn’t the same with about another 2-3 inches growth as well to both antlers.
I think between weeks five and six shows the biggest difference with about 3-4 inches of growth on main branch of antler as well as the first points branching off.
Weeks six to seven her right antler seems to have gained some good height to it growing very tall. At this point her antlers were bigger than one of our main breeding bull, Kota.
Week 8
Week 9
So there you have it, a nine week antler growth process. It really is amazing how fast antler can grow and this is proof in the pudding. Thank you Fly for being such a great candidate.
One of our visitors recently decided to adopt a reindeer they’d met at the Centre, but called us up when they received their pack to let us know that we’d sent a photo of the wrong reindeer. The reindeer they’d met had been a pale brown, with a thick shaggy coat and small antlers, whereas the photo on their certificate was of a sleek black coloured reindeer with large bony antlers. Thankfully, we hadn’t got it wrong, but could totally understand their confusion, as the reindeer change in appearance a lot throughout the year.

First, there is the coat appearance. From May, the reindeer start moulting out their long winter coat, which, with 2000 hairs per square inch, takes about six weeks. They look incredibly scruffy at this time, but by around mid-July the whole herd look glorious in their short summer coat. This summer coat is a richer colour than the winter coat, so the white reindeer are gleaming white, and the darker reindeer are virtually black. The short coat exposes all of their angles, so they can look a bit gaunt, with angular heads and shoulders.

Summer in the Highlands is short-lived, however, so by September their long winter coat is growing through, softening their appearance and turning them into cuddly teddy-bear lookalikes. This coat is slightly lighter in colour, so the darkest reindeer are now a rich brown. Over the winter months, the sun gradually bleaches out the colour, so by April the whole herd are a similar washed-out shade, with only the pure white reindeer looking different. It is the worst time of year to become a reindeer herder, as the reindeer look almost identical, and I’ve had sympathy with Ruth, and previously Dave and Imogen, starting in April and trying desperately to work out who is who!

Whilst the colour of a reindeer varies depending on the time of year, a dark coloured reindeer will always be comparatively dark, and a light one will be light. There is one exception, in that some white calves are born a mousy brown or grey colour, with a white forehead. This white forehead suggests their future colour, and once they are a yearling they have changed into their adult silvery coat.

The other major change in appearance is relating to the antlers. Every year, each reindeer grows a full new set of antlers before casting them again at the end of the season ready to grow the next (hopefully better) set. From January to March, the male reindeer are antler-less, with the females usually losing theirs a little later, between March and May. Antlers are very distinctive, with each individual tending to grow a similar shape or pattern each year once they pass the age of about three. This is really useful for us herders, helping us to recognise the reindeer from year to year. Not much help in the period between casting the old set and the new set getting to a sensible size though! New herders are cautioned to try to “look beyond the antlers” and instead learn more permanent characteristics, such as the shape of their face.

There is a slight spanner thrown in the works though, as adult reindeer don’t necessarily grow the same size of antler each year. Antler size is determined largely by condition, so if reindeer are short of energy, they will grow smaller, more basic antlers – it’s pointless to waste energy on an amazing set of antlers if you don’t save enough energy for your body to survive! The three main reasons for sub-standard antlers are illness, rearing a calf, and advancing years. If a reindeer becomes ill whilst growing their antlers, the growth will be checked, and sometimes the new bone is weakened to the point that it breaks off, leaving the reindeer with short, oddly shaped antlers. Antler growth also checks when a female is about to calve, and the extra effort of producing milk to feed the calf can mean the antlers are considerably smaller than usual. Finally, once a reindeer is in their old age, their antlers often become distinctly short and basic – they are focusing their efforts on being alive rather than growing antlers for dominance.

It’s always entertaining for new herders watching the change in reindeer throughout the year, and sometimes peering in disbelief that the handsome reindeer in a photo is the same beastie as the scruffy fellow they know on the hill (as a side note, most of the photos for the adoption certificates are taken in September when they reindeer are at their smartest, with a fresh winter coat and recently stripped full-grown antlers). So if you do receive an adopt certificate with a reindeer looking a little different from when you met them, it is of course possible that we’ve got it wrong (we’re only human!) but if we check for you and confirm that it is them, hopefully this blog will help you to believe us!
