We always encourage questions on our Hill Trips; some are simple to answer whilst others get us thinking more and this particular question even inspired me to write a blog!

“Are reindeer colour blind?”

The simple answer is… no. Reindeer, like other species of deer, are not colour blind, although they do see the world in a different way to us humans.

If you take a look at the visible spectrum below, reindeer can only see the colours at one end of it. They only see the short (blue) and middle (green) wavelength colours. This means they can distinguish blue from red, but not green from red, or orange from red. Therefore, their vision is thought to be similar to a human with red-green colour blindness.

So, when us Reindeer Herders go out for a Hill Trip wearing our bright red waterproof jackets, the reindeer would think we were camouflaged with the green hillside behind us. And there was I thinking we stand out!

To get a little bit more scientific this is because humans have three different kinds of cone cells in the retina which can detect the entire visible light spectrum. However, deer only have two sets of cones meaning that they cannot distinguish the longer wavelengths.

However, as I discovered this is not the end of the story of how a reindeer sees the world…. fascinatingly, they are one of only a tiny number of mammals which can also see ultraviolet!

Humans can’t see UV light but it is in sunlight so we are exposed to it every day; suntans (or in my case freckling and sunburn!) are familiar effects of our exposure to it!

So this led me to ponder the question “why have reindeer evolved to have UV vision?”

Researchers think that reindeer have adapted to see in UV as they live in a very UV-rich world. It’s thought that snow reflects around 90% of the UV light that hits it, compared to snow-free land which usually only reflects a few per cent.

Therefore, reindeer have adapted to their white world and have taken full advantage of it! Their special ability to see in UV allows them to spot things that other mammals would miss and helps them to find food and stay safe.

In the frozen white Arctic where the vast majority of the landscape would reflect the UV light, there are a few things which would absorb it. Predators, such as wolves, who to us would appear camouflaged actually stand out to a reindeer as their fur (and also their urine – a sign of a potential predator!) absorbs the UV light making them appear dark grey/black against the white, snowy background. Clever!

Similarly lichen, a major food source for reindeer in the winter months, also absorbs UV light. So if there was a tuft of lichen sticking up above the snow it would also appears very dark allowing the reindeer to see it clearly, in stark contrast to the UV-reflecting snow.

Therefore, they can avoid animals which might want to eat them and instead find lots of delicious lichen to devour for themselves!

We’re always getting lots of interesting questions and I look forward to the next one which gets me hitting the books… and maybe even writing another blog!

Up on the hill in our 1200 acre enclosure there is a shed. We use the shed to house sick reindeer, catch the wild ones, and store all our hill-working tools and materials.

For the last couple of months we have had a visitor in our shed on the hill. A little female Pied Wagtail decided that the shed made an excellent house to hold her nest, and it even came supplied with a renewing source of insulation – reindeer hair!

Tucked neatly out of the way, hidden behind some spare fencing wire, Mrs Pied Wagtail laid her second-of-the-year clutch of four teeny-tiny Pied Wagtail eggs. With the reindeer hair lining, and her body warmth for much of the day, the eggs were kept nice and toasty through the variable Scottish summer.

On the morning of the 18^th of July, we walked into the shed to the shed to find four little chicks huddled up against the nest. A couple of days later we were greeted by the sound of cheeping, and were delighted to find 4 yellow open beaks hungrily competing for food. It is of course incredibly important not to disturb the mother on her nest, or the chicks whilst they are alone, so these photos were taken quickly whilst the mother was already away.

Pied Wagtails are a common British bird, often known by slightly unusual nicknames such as ‘Polly Washdish’, or ‘Dishwasher’. These names are thought to come from olden days when women would wash dishes in streams where Pied Wagtails were common. They are lovely, sprightly birds that appear very cheerful and eager with their wagging tails and chirping call.

By the 31^st of July, the chicks had fledged, and are now off in the big bad world, where we wish them all the best. We are always happy to see birds and beasts using our shed for shelter, and hope to see our little female Pied Wagtail back next year!

Every reindeer has their own name, based on a different theme every year. Last year the theme was ancient civilisations but we have also had more ridiculous themes such as pop stars (Elvis, Marley, Blondie) and cheeses (Feta, Mozzarella, Brie). However, with almost 160 reindeer in the herd, there is a lot of reindeer to identify and name! I work as a herder during the summer which is a bit easier for identifying the reindeer, so this blog will describe how I go about naming them.

In the summer the reindeer’s antlers are nearly fully grown and most have distinctive shapes which grow back the same every year. The big breeding bulls usually have huge antlers that stand out amongst the crowd, for example Bovril, who has large dark antlers with two big blades at the front (the blade is the part of the antler witch grows downwards over their face to protect it). The Christmas reindeer (those who have been castrated to control the breeding) usually grow smaller but more ‘messy’ antlers that go off in all directions. This year Nutkins, a very friendly five year old, has small antlers that have parts growing in around seven directions!

 

Another main difference for the reindeer at this time is they have moulted their thick winter coats to reveal their much thinner and darker summer coats. There is a lot more variety in colours between these, some being very dark, such as Orkney, or much lighter like Origami. A few also have interesting facial markings such as Laptev who has a pink nose. These reindeer are all so distinctive that they can be identified from a distance.

 

Origami saving some energy walking on the board walk. He has completely moulted his winter coat in this picture, which is almost pure white in places, unusual for a summer coat on a reindeer.

All the reindeer have different personalities. On hill trips it is usually the same group of four or five reindeer that come up for hand feeding and don’t leave until all the food is gone! This means that all us herders can easily identify the greediest reindeer in the herd (such as Orkney as mentioned before).

If the reindeer is normal coloured with ordinary antlers and a shy personality, identifying them can be harder. In this case we can get a bit closer to the reindeer and look at their left ear which will have a coloured ear tag. Every year has a different colour of tag and a different theme for naming (eg. 2013 was a yellow tag and the theme was cheeses). There is usually only three or four reindeer from each year so it is easier to narrow it down and work out the differences between them in each year.

If all else fails, we can cheat! Every ear tag has a different number and each herder has a herds list so we can easily look up who it is we are struggling to identify.

Most of the reindeer mentioned in this blog are currently up in our hill enclosure so if you’re planning a visit soon why not try and identify one for yourself!

Hello, my name is Olly; I’ve been working at the Reindeer Centre (on and off) for about 3 years now. I first came up volunteering for work experience when I was studying Countryside conservation and Wildlife management at Sparsholt College. I started once more this season in May and since being here there hasn’t been a dull moment.

I keep on being badgered to write a blog but I have never been sure what to say. I am also dyslexic and so unfortunately writing is not one of my favourite things to do, but… I do like to take pictures! So here are some photos of mine that I have taken since I have been back with my perspective on them. And as they say, “a picture paints a thousand words”..

Picture 1: May time is calving time, which means its time for 5am starts, in our search for the newborns out on the hill. I often like an early start (as long as I have a strong coffee) as you’re seizing the day. What a day it was, not a cloud in sight and just a soft cooling breeze with the hill alight with the morning sun. I was also excited to see Black Grouse lekking in the enclosure. We eventually found the new mother Gazelle and her wee one, who was a strong healthy male.

 

Picture 2: One thing I love about it here are all the lochs and rivers, as a few of us at the Reindeer Centre made a New Year’s resolution to jump in a fresh body of water once a month or week. Trying to do this down south was rather difficult and I had to go to the coast to achieve it. But now in Scotland there’s somewhere to swim around every corner. Since being back I have been in 5 different lochs and a couple of rivers. It may be cold at times but you’re surprisingly warm once you’re out, athough I’m usually on a run when I do jump in so the blood is pumping. But I highly recommend an occasional dip.

 

Picture 3 and 4: The long socks and trainers were on, my belly was full of stew and the calf was well rested…. It was time for the cows and calves to head out on the free range. We headed out late in the evening to lessen the chances of us bumping into dogs and as we came over the brow of the hill the hills were looking fierce, but the show must go on.

With Tilly leading one of the females (Fern) on a halter; myself, Fiona, Morna, and Ceris followed from the sides and the back in case the reindeer decide to go their own way. At one point they did, but we managed to get them on the right path in the end.

Pushing them out wasn’t so bad. All you had to do was keep the right distance – far enough not to scare them but close enough to keep them moving. Apart from almost falling off the edge of a scree at one point it was just a case of getting them far out in to the hills. As we let them run off, it was rewarding to see calves running up in to the hills alongside their mothers.

Now came the race against the light! We were lucky and just as it became pitch black we made it back to the van, although going through the trees past Utsi’s bridge was rather eerie. We eventually got back to Reindeer House and celebrated with a wee dram.

 

Picture 5: The woman in this photo herding the reindeer is called Sally. She often wears a shirt with a sunflower design on it which suits her personality to a T. She brings sunshine to Reindeer House as she is a true pleasure to work with, and has to be one of the jolliest people I have ever met.

 

Picture 6: Though our days are busy and the hills and forestry tracks are a hive of activity, once the clock reaches 5:30pm Glenmore turns into a ghost town. With the sun setting late in the evening, we go to the hills. It is treat to have this on your doorstep and is a grand way to end the day, by gazing into the distance of this colossal landscape. It really makes you think how small we all are.

So what’s the deal with leucism?

Are all white reindeer leucistic?

Are all leucistic reindeer deaf?

How is leucism passed on?

How is leucism different to Albinism?

These are questions I have pondered while fixing the boardwalk, closely accompanied by Blue, our male leucistic reindeer. The subject of leucism is quite hotly debated and seems only those with a Doctorate in Pathology may comment, but here goes:

Leucism (pronounced loo-kiz-im) is a genetic peculiarity which gives a white colour. The condition is recessive. It is a defect in the skin, not the pigment cells. Leucistic animals are all perfectly white. It seems however that there are differing levels of the condition – partial and full.

One other characteristic of leucism is deafness, however is seems that this is not always the case. Leucism is developed during the early stages of embryonic development and can influence the central nervous system. It therefore most commonly affects sight and hearing.

If a condition is recessive it means that the offspring must receive the leucism gene from both parents to develop the condition. We have leucism in the herd. It doesn’t affect the carriers at all but if they breed with a carrier there is 25% chance that their offspring with have leucism. We currently have two leucistic Reindeer that are both deaf – Blue and Blondie.

Blondie’s(ll) father was Sirkas (Ll) and mother was Glacier(Ll) both carriers, therefore there was a 25% chance that Blondie was born with leucism. Glacier had nine calves of which only one was born with leucism but of course several carriers.

Blue’s(ll) father is Lego who had leucism (ll), Blue’s mother is Lulu who was a carrier (Ll). There was therefore 50% chance that Blue would be born with leucism.

Albinism is a total deficiency of melanin producing cells in the skin. It is a skin mutation. There is a total lack of pigment. Albino animals have pink/red eyes. The pigment (colour) that would normally be seen in our eyes is missing so the blood vessels behind are seen in the eye, given the appearance that the eye is red in colour.

As I do not have a Doctorate in anything (except drinking tea) these are not comments but merely my interpretation of several articles written by Doctors of Science.

The Cairngorm Reindeer Herd was established in 1952 so over the past 65 years there have been many main breeding bulls so here is a little sum up. I can only tell you about the ones I remember but there were many bulls before my time as well. I’ll try to inspire Tilly (or Alan) to write a blog on the ones before my time.

The first bull I remember when I was very young was Gustav and he was born in 1985, the same year as my brother. You could not get a more gentle reindeer, if he was a human he would be the perfect gentleman! I suspect nowadays we have lots of reindeer in the herd like Gustav but back in the day he was certainly one of a kind! You may find this morbid but a few years after Gustav died we found his skull so we hung it up in our shed on the hill so we feel like he watches over us when we bring the herd in for handling. He was the main breeding bull in 1989, 1990 and 1991.

The next one to memory was Crackle who came to us from Whipsnade zoo in 1991 along with two others, Snap and Pop (Who remembers Snap, Crackle and Pop from Kellogg’s Rice Krispies?). Being new blood we obviously wanted to breed from him. He was also a very good looking reindeer, grew lovely antlers and had a great temperament so all good things to go back into our herd. He featured on the front cover of Tilly’s first book ‘Velvet Antlers Velvet Noses’ and lived to a grand age of 16. He was also photographed by wildlife photographer Laurie Campbell and recently we have acquired some posters from Laurie which were printed many years ago when Crackle was in his prime which we are selling in our shop.

After Crackle was Utsi who was born in 1998. He was hand reared by Alan, my dad. Utsi’s mum Pepper died when he was very young so we bottle fed him milk and he was Alan’s shadow around the hill and farm. I had a love/hate relationship with Utsi… and not because we fought over Alan’s attention, he well and truly had that 😉 When I was in my mid-teens on the hill one day with mum, we fed the herd and I was walking back counting them. At that point Utis was rutting and decided I was a few steps too close to his females and he completely flattened me. There were no injuries, infact I managed to get myself in-between his antlers while on the ground and held him into me as mum came over flapping an empty food sack to shoo him away. He headed off leaving me in a wee pile on the ground, but un-injured! The trouble when reindeer are hand-reared is they see us as part of their herd and being totally comfortable in our company he wasn’t scared to give me a telling off for getting too close so it’s a fair one really. I’ve learnt from my mistakes and how to act around rutting bulls so there have been no incidents since. The same year Utsi was a breeding bull we also had Cluster who was the same age. He was very different, kept himself to himself but grew lovely big antlers. We also had Red who was another gentleman, good looking with a super nature!

We then had a spell where we used bulls we brought in from Sweden in 2004. This was new blood in the herd which is very important but it meant there wasn’t necessarily one main breeding bull. Some of these bulls were Sarek, Sirkas, Jokkmokk, Ritsem, Västra, Ola, Moskki and Porjus.

Then there was Crann!!! If you haven’t heard of Crann I’d be very surprised. He has been the pin up boy of the Cairngorm Reindeer Herd for quite some time now and although a very old man at 14 years he is still with us… though not looking as quite as good as he once was. None of the past or future bulls have matched the size of Crann’s antlers, he still holds the record and I suspect will for a long time to come. He was truly magnificent in his prime and his photograph has been in many national newspapers as well as our own advertising and images on various items of shop stock. He is certainly enjoying full retirement now at our hill farm over at Glenlivet, and quite rightly too!

So in the more recent years we have had more reindeer joining us from Sweden. In 2008 we brought over Pelle, Jaska, Bajaan and Magnus who were the main breeding bulls around 2009, 2010 and 2011. Then there was Gandi, Bovril, Jara, Lalle, Boxer, Kota, Houdini, Pera, Bandy and Nutti who joined us in 2011. The most recent Scottish bulls are Balmoral and Ost. Both from very strong family lines and they have lovely natures and grow beautiful antlers… everything you want in a reindeer!
