By the time you read this, the rut will be underway here at Cairngorm, with our chosen breeding bulls split with selected unrelated females, to make sure we know who the parents of each calf are. While the bulls tend to be fairly relaxed and laid back for most of the year, as September comes to an end and the cows come into season, they start to “rut”, strutting around, posturing and rounding up their females, and challenging any other bull they see. Reindeer bulls don’t “roar” like some deer species (including the iconic Scottish red deer stag), instead they grunt. But one of the most noticeable changes for me is their smell.

Now, I don’t claim to have a particularly good sense of smell, but in general reindeer are fairly unsmelly creatures. However, a rutting bull is a different matter, and already, as I write in mid-September, our boys are getting stinky. It’s not an entirely unpleasant smell – very musky and, well, masculine I suppose. One of the main reasons they smell so strong is that they begin deliberately peeing on their hindlegs. This always seemed a bit odd until I did my research and realised that reindeer, like all deer, have scent glands on the inside of their hocks, the tarsal glands. This gland produces an oily secretion, and when the natural bacteria on this area combines with pheromones in the urine, that distinctive scent is produced. Apparently every reindeer has a unique, individual scent, due to their own winning combination of bacteria, though I definitely don’t have a sensitive enough nose to be able to tell!

Why do they feel the urge to be so stinky?? Well, part of it must be as a statement of dominance – when I, as a mere human, can smell a bull from 100 metres away, the other reindeer must be able to smell them from… 800 metres?… a mile?? This must act as a deterrent to a weaker bull, and quite possibly as an attractant to a female in season – they definitely come looking for bulls when they’re ready.
Feeding the big bulls last year, just before the rut – they were already stinky!
We have a vague theory among us herders that the female herders notice the scent of the rutting bulls more than the male herders do. Quite what that means, I have no idea – perhaps the smell is designed more as an attractant to cows than a deterrent to bulls after all (not that any of us lassies have said that we actually like the smell!). Either that or the men amongst us are less sensitive when it comes to body odour!
The reindeer I’ve chosen to talk about in this week’s blog is a reindeer who I like a lot. I met him when he was just hours old and he has now become one of the breeding bulls for the herd. His name is Spartan. He was born in 2016 and was named after that year’s naming theme of ‘lost civilizations’. This means he’s about 5 years old and is coming in to his prime. In this blog I’d like to talk a bit about Spartan’s journey from unassuming calf to sweet-natured breeding bull as well as his heritage and his offspring.

During Spartan’s first year of life he was always an unassuming calf. He wasn’t exactly oozing in character and was a relatively quiet calf. He was always polite and never pushy, and he grew very simple antlers. However, as you can see from the photo below, his antlers are far from simple nowadays. They are one of the largest and most beautiful in the herd.
What a bonny lad!
From a personality point of view, Spartan really grew into himself over the years. He has a sweet, lovely nature, even during the rut. For those who don’t know, the rut is a period in autumn – about a month in duration – where reindeer come into season and the breeding occurs. Breeding bulls are known to alter their nature and become more territorial which can lead to these bulls being more scary and aggressive (hence why we don’t visit the breeding bulls on hill trips in October/November). However, Spartan remained well-behaved despite being swarmed by hormones. Compared to our other breeding bulls he is definitely on the well-behaved end of the spectrum. Perhaps this was due to his much-loved mother, Bumble, being incredibly sweet-natured and passing on those genes to her son. If you wanted to read more about Bumble, you can read a blog on her by clicking here.
Bumble – a monstrously greedy reindeer!!!
Spartan had his first experience of being a breeding bull in 2019 and is believed to be the father of 10 calves that were conceived that year and later born in 2020. However, the selection of Spartan as a breeding bull wasn’t an obvious selection. Each year we have to make the decision of which young adult male reindeer we want to pass on their genetics for the future of the herd, and which reindeer we want to castrate. This decision is made when the male reindeer is at least 3 years old and is integral in keeping the number of reindeer in our herd to a sustainable amount. Moreover, by controlling the breeding it means that we never have to cull any reindeer. When it came time to select which reindeer were to be castrated from the 2016 year we decided that we would keep 2 reindeer as breeding bulls that year. Roman was the first choice and after lengthy discussions, Spartan’s genes seemed to win out over other contenders such as Aztec and Celt. He kind of snuck through the castration net, so to speak.

Spartan comes from a blood line that had almost become lost within our herd. And now that he is one of our few breeding bulls, it means that the blood line has a new lease of life. Spartan’s father was the popular breeding bull Nutti who was imported as a calf from Sweden in December 2011. We imported a large amount of young male reindeer from Sweden around that time as we wanted to diversify the genetics in our herd and introduce more blood lines. Nutti unfortunately died in April 2018 whilst free-roaming in the Cromdale hills but as you can see from the photo below, his genetics live on in Spartan whose looks, and indeed nature resemble that of Nutti.
Nutti – explaining where Spartan’s face marking came from!
In 2019, almost immediately after the decision that he would become a breeding bull, Spartan was put into the rut and introduced to his own group of females that were coming into season. It turned out that the other breeding bull contenders were related to more of the eligible cows than Spartan. Therefore, we believe he is father to a group of 10 lovely calves (now yearlings) all of whom were named after ‘peas, seeds and beans’. The calves that we think are probably Spartan’s all appear to be very sweet natured and endearing. They are Cannellini, Lupin, Hemp, Chickpea, Mushy, Pinto, Edamame, Adzuki, Borlotti and Haricot. And with only a few exceptions, many of the calves have distinctive white face markings, just like Spartan. These are most notable on Pinto, Edamame, Hemp, Borlotti and Adzuki, the offspring of Morven, Emmental, Addax, Clootie and Gazelle respectively.

Although we didn’t use Spartan in autumn’s rut of 2020 he retains his ‘equipment’ and his name is being discussed as a potential breeding bull for this year’s rut. He is currently in great condition and is having a very peaceful year! In the early months of 2021 Spartan has been free-roaming on the Cromdale hills.
So there you have it! The story of Spartan – one of our friendliest breeding bulls.
Since some of our female reindeer finally decided to join us at the hill enclosure, the rut has got underway. We use different sections of our 1,200 acre hill enclosure to help us manage the bulls during the rut, as it would be complete chaos if we just put them all in together and left them to get on with it! By splitting each bull with a small group of females, everything is a bit more relaxed and the big lads feel less at risk of losing their girls. We do, however, let some of the younger, smaller bulls “have a go” by letting them remain in with a big bull, and if they manage to sneak a female away and have their wicked way, then good for them. Of course, most of the time, they don’t stand a chance!

This year we have quite a few bulls who may be getting a chance to spread their genetics in the herd. As usual, most of these are of Swedish descent. Whilst we keep a record of the parentage of each calf born here, it is a lot easier to prevent inbreeding and promote genetic diversity if we use bulls that we know aren’t related to anyone else. Bovril, Gandi, Boxer, Nutti, Pera and Bandy all started their lives in Sweden, before joining our herd in 2011. After we have bred from them for a few years, they will join our Christmas team and live out the rest of their life as a part of the Cairngorm herd.
Big handsome Bovril
Bovril and Gandi are perhaps the biggest and most impressive of the boys this year, especially Bovril as he is black in colour, and whilst he’s actually very sweet natured, when he’s strutting his stuff and chasing away the other males he can look extremely intimidating! Pera is another black reindeer, but is slightly smaller than Bovril. He is easily recognised due to having rather bizarre antlers – the top points point forwards rather than backwards. As antler shape is determined genetically, it will be interesting to see what the antlers of Pera’s offspring turn out like!

Boxer is another dark coloured reindeer, but Nutti is much lighter and has a white nose, as does Gandi. Bandy is the one right in the middle – what we would call a “normal” colour. He’s quite a slight build and a bit less scary than the other big bulls, but is perfectly capable of holding a group of females.

Of our Scottish born bulls, three-year-old Balmoral is the biggest and most impressive. He comes from a great family line – Fly is his mum – and his family has a good record for producing big strong calves with large antlers, so hopefully any offspring he fathers will inherit these traits. A few of the younger bulls may also get a look in – notably Cambozola, Mo and Atlantic are convinced that they are handsome enough to win over any female… its just a case of whether they can steal them away from the big lads or not!

Watching the bulls performing is always entertaining – unlike the red deer stags who roar their challenge at other males, reindeer bulls merely grunt. They also lick their lips, pee on their hind legs and generally swagger around thinking they’re the bees knees. Personally, they remind me of drunken lads out on the town, but they do seem to have some degree of success at impressing the cows. Quite how successful will only be proven next year in May!
