Back-dating the Somerset Cat.

On Monday, I went on a field trip. Field trips in Geology are a common occurrence; what better way to learn about rocks than to get out there and look? We were off to a place called Vallis Vale in East Somerset, the site of an unconformity. An unconformity occurs when sediments are laid down, folded so the beds lie at an angle, and then eroded.
Younger sediments form on top of the old sediment in typical straight beds, and an unconformity is created. They are only visible when falling sea levels and colliding continents cause the unconformity to rise above “normal” ground level.
Cutting by a river or quarrying also helps. You can see in the photo the different dips of the beds. The beds themselves can be dated by looking at the fossils within them; the rock below is from the Carboniferous period, and the rock above is from the Jurassic. This site is geologically important as it was described in the world's first Geological Survey memoir in 1846 and helped establish the science. Anyway...


In the minibus on the way up, through the sounds of Rush’s “2112”, I overheard my teacher talking to the lad sat in the front seat that he had seen a “black panther” crossing this road at night. I realised where we were, and found that we were about 800m from the field in which the big cat has been killing dozens of sheep! Hooray!

The next day I stayed behind to ask him about it. He said he had been driving along the road at about 2145 to take his son’s babysitter home, when out of a wood on the left this Labrador walked out onto the road. He stopped to see if it was ok (clearly a dog walking around on its own is a cause for concern), but it suddenly dawned on him that it was a big cat. He stopped the car and watched the cat watch him. It carried on it’s way to the right, and he can remember clearly pressing the button to wind the window up; just in case.

He also said that his first encounter of big cats (or rather, something) happened at around the same time when climbing in Cheddar Gorge. He was getting up to the top of the ridge in an area where no people go because it is very heavily wooded. He got to the top of the ridge, and found an area of scraped ground with a large mound of foul smelling dung deposited inside. He didn’t recognise it as being something he was familiar, but he left it due to the difficulties in getting it back down again.

My teacher is not unknowledgable when it comes to animals; parts of teaching geology necessitate a good knowledge of the natural world, and I would take his account as highly credible. The diagnostic features he remembers are; very long thin tail, jet black colour (“such that if it was hidden in bracken or a ditch, you could come within 3ft of it and not notice it was there” he said), slightly pointed ears and a very calm demeanour. It’s total length was about 2m long.

This is all very interesting, but there was one more thing. The sighting happened 14 years ago.

Walking in a Winter Wonderland

Back in early February, as I am sure you remember, the British Isles had a flurry of snow. Here in Somerset, we had our fair share, and I - being the good field-man I am - went up to the usual place to see if Mr. Kitty had left any traces of his existence. The farmer had moved his sheep away into shelter over the cold snap, so I knew that there would be no new kills to poke.


I battled my way up to the field, parked up, got out and had a look around. I was extremely surprised to see the amount of snow prints I did (nothing feline though), and got round to the fun business of identifying them all, as all good naturalists should. Now, I know what most of these are, but the real question is, do you, the CFZ blog readers, have any idea what these prints are from? The person who sends in the most accurate answers as to what the following 8 photos show wins a year’s subscription to either The Amateur Naturalist or Animals & Men magazine, it’s your choice! Answers can be sent to max@cfz.org.uk. The number at the end of the text next to the photo shows the question number.


First up, we have this image. Any ideas? They are right down to the ground (3”), so we must be dealing with something with fairly small feet for its body size.


The two prints are about 6” apart, and each print is 1.5” wide. Claws are clearly visible, which are short but thick. The central pad is also diagnostic. [1]






Ok, now try this. We have two prints, which plunge very deep into the snow with a pretty large amount of kicked back snow. The prints are about 1-1.5” in diameter, and are about 1’ apart. [2]


Moving briefly to a photo I took near my house, what have we here? We have thinner snow, maybe an inch, with two sets of prints. One very large long one and two smaller distinct prints. The prints are about 2” wide. Any ideas? long one and two smaller distinct prints. The prints are about 2” wide. Any ideas?

And this one? An odd one this. The snow is very thin here. [4]































And this? Four points originating from a central source. [5]


































Right, let’s get tough. The next few photos are fairly indistinct, and I won’t be adding my suggestions and hints for any of these. Good luck!

Oh, and just for fun, this is the amount of prints that you get around a decaying carcass as scavengers, errr, scavenge for meat left on the bones.

The CFZ solves another mystery!

And then, as if by magic, just when I had finished writing the previous blog, I got an email from a contact from the local news who said “One of our readers e-mailed me these this am. I’ve had a long chat with her and she is convinced they are a big cat’s prints. She heard a big “kerthump” as if it was jumping down. She has fields and woods around her and just three houses up there. Lots of deer in the fields. She is on the Cranmore side of Doulting. I said I would pass the photos on to you to see what you think. Her details are below and she is happy to talk to you. I have sent her copies of the stories we did as she had not seen them.”.


Attached were two photos, one showing the print, and the other showing the stride length. They looked pretty damn canine to me, but for a second opinion (always important) I passed them (again) on to Richard Freeman, who had this to say:

"These are clearly dog tracks. The concave shape of the main pad can be seen in the first photograph. Also, the toes are symmetrical and show the blunt claws of a canid. A cat's claws are finer and only seen in prints when unsheathed for a firmer grip on slippery or uneven surfaces. A cat's main pad has three bulges or lobes akin to the shape of a club in a deck of cards. The toes on a cat are asymmetrical unlike a dogs."



I don’t think I can add anything to that! Never mind, at least the CFZ now has a very good photo of what a dog’s print in the snow looks like!

I did have chat with the person who took the photos, and the fact that she lives next to a field in which a few dogs are walked closes this case. Apart from one thing: “She heard a big “kerthump” as if it was jumping down.”. This does sound a bit odd, until you realise that the prints were in her garden, and to escape the dog would have had to jump over the fence, creating the “kerthump” noise. Case closed.

But, the journalist who sent me this case also mentioned that she is “trying to check out the report from the lady from Cranmore who was saying she heard something big snarling in the bushes near her home last month.”. Now, as you can see, Cranmore is very close to the place where the lady found the dog prints. Naturally, I will keep you updated.

The launch of the UK Alien Animals study group

Hooray! A new venture for both the CFZ and for its shortest member, myself. Alien animals, as we define them, are animals inhabiting a habitat where they are not native. These can be animals which have been introduced into new areas by human intervention, animals moving along pathways which have been created by human activity, or animals which have expanded their range into an unexpected area through natural process.

During this quick introductory post, I will be having a quick look at examples of alien animals in Britain, discussing our plans for the future, and finally, looking at what you, CFZ members and representatives, but first and foremost naturalists, can do to help our studies.
So first, some examples. New area introductions are numerous and well known.

The coypu is a great example. Introduced into fur farms in 1929, this large (4.5-9kg) rodent swiftly made its escape, and soon found that the habitat in East Anglia was very much to its tastes, where it settled and bred very nicely. This news was initially taken as good tidings: Coypu eat a lot of reeds and would clear streams wherever they went, keeping them free flowing. However, it was soon found that they loved vegetables from gardens, and crops from farms, plus their reed clearing activities and burrowing would only cause the river banks to be undermined and collapse. Their only predators big enough to take the babies in Britain were foxes, stoats and herons; they would leave the adults (if only we still had wolves...).

Now, you may be saying to yourself “Well, this is all well and good, but in their native habitat [throughout South America] surely they would cause a huge amount of damage to the area?”. Well, no. Coypu in Britain had hit such densities thanks to so much food from our farms that their numbers could sky rocket. Indeed, some clever ecologist worked out that only when Coypu hit a density of 4 per acre, do they begin to cause large amounts of damage. A huge number of Coypu living in one area of course results in far more burrowing structures than normal, causing bank undermining, and increasing the risk of flood damage.

So, that is new area introductions dealt with, but what about new pathway introductions? This is a bit of an odd term, and I will try to make it clearer. When animals are removed from a food chain, a gap appears which may be suitable for another animal to exploit. For example, by removing top predators like wolves and bears from Britain, we have produced a gap which will be filled by evolution (maybe not now, but certainly in the future, evolution can take a long time to work!). So, by removing these predators, there is a top spot available which is just beginning to be filled by (for the purposes of this article) two types of animal. 1. Big cats, 2. Eagle owls (amongst others)

Big cats, you are quite right, are new area introductions, but they have adapted to new pathways which we have left open. Eagle owls however, may or may not have been present in Britain in recent times before extermination, but they are back! Some birds are undoubtedly captive releases, but some of them I am sure are birds who have flown over from the continent, found a huge amount of prey (from voles to rabbits and even up to buzzards (who incidentally have moving up into that top carnivore slot)) available, so they decided to stay here.

There is currently a male Eagle owl who lives outside the Biology building at Bristol University, which does push this university a little higher up my favourite list for next year. This young fellow is almost certainly a captive release however, but it is still quite interesting! Eagle owls enjoy a bit of a love hate relationship with people, they are stunning birds which people love to see flying around, but when it turns out that they may eat the occasional game bird, the shooting lobby fires up (pun intended) to claim that they should all be shot.

I have nothing against game shooters; indeed, working on a shooting ground has shown me the great help they can be to keeping some species of British bird breeding on land which would have otherwise been eaten up by housing or farmland. The great expanse in breeding areas for game birds must be a good thing, for, as Pink Floyd said, “the price of a few hundred ordinary lives”.

So, that is the basics sorted out. Now for our aims.

We hope to set up a sighting and watch database where we log sightings of alien animals alongside notes about their environment, activity and numbers. We are looking to produce a book by the end of the year: either it will be a monster of a book looking at every alien animal in Britain, from the confirmed to the unconfirmed; or it will be a book split into three parts:

  • Mammals
  • Birds
  • Reptiles, amphibians, and fish
  • Invertebrates

but we shall have to see.

The most important factor in making this venture work is you! The people up and down the country who want to help this project go. You can do so my informing either Jon Downes or myself of any sighting you have of an alien animal, together with as much information as you can get about it (not the animal species itself, but what they are doing there, their size, estimated weight, habits, food source etc), or by suggesting ideas and suggestions to helping this get started. We hope to have you on-board soon.

The cat came back


After me bemoaning the fact that there were less and less kills from this ABC in my area, it seems once again it is time to pop open a Beast (fear not reader, I will explain all).

Yesterday as you are all aware was Saturday, the day I fire up my car and zoom off to work to earn an honest buck in order to keep myself and beer as close friends. Now, the day was fairly unspectacular (other than the freezing cold conditions) until it got to around 1400, when one of the shotgun coaches said to the three people he had just been tutoring “Ah, here’s the chap you want to speak to.” as I wandered past. One of the gentlemen proceeded then to tell me that he had a big cat in his area (Taunton) and that it was killing sheep.

It had been through a fair few apparently, but the only bodies my contact had seen were those that the farmer had shown him after he had dragged them in from the field. The sheep’s pelt had been taken off the bones, and the only bones the farmer brought back were the spine, ribs and skull. Now, this proves very little (ie, was the killer a cat, canid or just an excuse) as the sheep had been moved from, what we would call in palaeontology, life position (you can think of it as being moved from its exact position of death). The sheep killed were all grown on lambs at about ¾ of full size.

This is very interesting indeed, and I have exchanged emails with one of the chaps who will provide me with photos when he can. I intend to get up there as soon as I can. This is probably not the same cat that I have been dealing with closer to home, but 25 miles away as the Raven flies (or as the Leopard runs for that matter) is, although seemingly large, not completely out of the question. Remember, an ABC in the wild would probably not have a territory this large, but this is not their wild habitat (with the possible exception of Lynxes). We have no idea how they behave when their prey is confined to a comparatively small area of land and are fairly easy to catch and kill. Will their territory size increase? My feeling is that yes it will do. Territory size is controlled mainly by two factors, how many competitors there are nearby, and how much food there is nearby. So, taking a Leopard as an example, lots of Hyenas and Lions around will diminish its territory size, and lots if easy to catch prey with a high nutrition value will again, diminish it. Few competitors and hard to catch, low energy prey (rabbits for instance) will both increase territory size. Note, low energy prey is prey that may be low in calorific content (or whatever measure of nutrition you want to use), but also take a lot of effort and energy to catch. For a Leopard of 80kg, a Rabbit which might get to 1kg is much more energy intensive to catch and eat than it is for a 10kg Fox, hence why Foxes take a lot of Rabbits.

Here in the UK, we can see a large amount of easy prey (expected to reduce territory size), but a low population density and little competition (expecting to increase territory size). I would expect with the evidence available to me that 25 miles for a territory is not as mad as it may at first seem for a Leopard/Puma/whatever. Just to err on the side of caution however, I would say that this is not the same cat.

Now, that lot is good for a day’s work. However, it gets better. I got home, showered, ate tea and then went onto the computer to write an article about keeping beetles for Exotic Pets magazine. I went onto an invertebrate’s forum, (on which I am the moderator of the beetles, aquatics and cockroaches sections) to check how things had been over the last day, and what did I find? Someone had posted a thread in Off Topic about big cats in Britain. Obviously I looked at it, and I was really surprised at what I found (I will not repeat the thread here, but you can go and look at it if you sign up as a member for Bug Nation).

The jist of the thread is that one of the forum’s members had noticed in the local paper (the Hastings Observer: http://www.hastingsobserver.co.uk/509/Bumper-year-for-big-cat.3674641.jp) that there were big cats in the area, and was wondering what people’s thoughts on them were.

Now, attached to one of the thread starter’s posts was two photos which her other half had taken. One was of a large paw print in some mud, and the other was of the plaster cast this person had made of it. This is a brilliant example of people (one wants to use the phrase “general public, but that would be a touch insulting) using their initiative, getting something done and helping us all out. Good job!

Unfortunately, I cannot tell if it is a cat or a dog, as although there are no claw marks, the back of the central pad is obscured by a lighter used to show size. The pad is the same length as the lighter, and the whole print looks to be about 1.5 lighters tall, within cat size. The digit pads are close to the central pad and are all of similar size. I have contacted the member to see if I she can get some better photos of it for me, and obviously, I will keep you all updated.

As for that thing about the Beast, well, it is a little tradition I have.

Whenever something big happens with my big cat research, I open a bottle of one of my favourite ales, Exmoor Beast (a superb dark ale with a strong chocolate and hops flavour) which depicts a melanistic leopard jumping toward the drinker. As proof of this being a good day for me, here you can see me drinking aforementioned beer...

The Raven's Revenge

The Raven (Corvus corax) is, at a maximum of 1500g, Britain’s largest crow. It is an omnivore, but its specialty in Britain is scavenging from dead animals. Its size puts it pretty near the top (for birds at least) of the scavenging chain, and it can easily intimidate smaller scavengers like carrion crows into giving up the lion’s share of the dead animal. Since the 1500s it has been persecuted by Sheppard’s and gamekeepers for scavenging or eating young animals and by the late 19th century it was confined to the west coast where the craggy cliffs it nested on afforded it some protection. Only after the First World War did the persecution slow and the Raven’s number begin to build up as it adapted again to tree nesting. Since then it has gone on to spread slowly inland, into Wales and Cumbria as well as making inroads into Devon. I had thought that the Raven was a species not really found in Somerset (where I currently live) and if it was at all to be found it would be far over to the west near Minehead and Watchet. I was, however, to be proved very wrong.

On Christmas Day this year, as you will remember, I was out and about doing some big cat research. After getting into the field, I saw coming towards me as I stood in the field was a crow, a “bloody huge one” if I remember myself muttering. Anyway, I carried on and ignored the bird. This was at the same moment that it flew past me and turned around over my head calling a deep throaty “prrrrruuuk”. “Raven!” I burst out. And indeed it was. Not just one, but four Ravens seemingly in two pairs.






After taking some photographs of them (as well as some rubbish video footage) I started thinking why were they here? Back at home I did come research on the subject, and found that Ravens are indeed found throughout Somerset, but they are few and far between with breeding occurring in Glastonbury’s Ham Wall reserve and across the Somerset Levels. Even though I had spend considerable time up at the killing fields, I had not noticed their presence at all, but seeing as on this day there was a freshly killed sheep, I am guessing they were in the area for this. The sheep’s eyes had gone, so one would suspect the Ravens of being the main scavengers of these from the kills. After following them for a bit on that first day, I found that one pair seemed to be spending a fair bit of time down on the quiet side of the quarry; it could well be that this is their perfect habitat: craggy cliffs for nesting, an abundance of food in the form of dead sheep, and no persecution. I for one am overjoyed at their comeback to Somerset, even if it is at the expense of a few sheep to keep them interested. Ravens begin nesting in January and lay their eggs in March, so it may be time to spend a while searching for their nest.




I have seen the Ravens twice in the four times I have been up there in the last month, however, I have not seen any sheep kills in this time (apart from possibly one) so it could be, as my best friend suggested when we went up for a look around early last week, that the cat has perished in the freezing temperatures that we experienced in late December. I need to get back to the field to see what’s changed, plus chase up the farmer and water board about the CFZ’s stolen trigger camera.


In other big cat related news, I was interviewed on Wednesday by the superb Geoff Ward who writes the “Mysterious West” page in one of the local newspapers. The interview will go up as part of his weekly podcast, and I (or more likely, Jon) will add a link to it when it is edited and published. I know full well I answered a few questions in the daftest possible manner (for instance, answering a question along the lines of “If big cats are comparatively numerous, why has no-one trapped one yet?” with “Well, in one night outside a large southern African city they trapped 27 leopards.” which means very little), but hey, it may just bring an extra bit of knowledge into people’s minds along with someone to contact if they do see something. It’s all about spreading the word...

PS, I apologise for this, but Fleur wanted to see some photos of me in my cat catching gear, but I only have one good one and im not even wearing my wide brim hat, but never mind:

Beginning the cat hunt

Back in November I got involved in trying to prove the existence of a (or possibly more) big cat living and killing sheep about 15 minutes down the road from me. A farmer had had about 30 sheep killed within the space of just over a month and he wanted some help in verifying it as a big cat. He had seen it alone more than once, and had seen a pair (one larger than the other) once. A paw print had been found, and by the description he gave me it fits a large cat (possibly puma, possibly leopard). I photographed what I could see of the kills [one photo showing the hole from which the organs were eaten is attached] and went up to the field repeatedly to try and work out what was going on. For a while I was about 60% sure that it was dogs doing the killing, and that a big cat lived in the area.


Then something very interesting happened. In early December I was phoned up by my employer who told me that a big cat had been sighted by 3 people moving across the shooting ground’s (shotgun that is) land! I must add here that this was not a cat walking calmly amongst layouts where clay pigeon shooters stood looking on in disbelief. The cat had walked around the back of the layouts, through a field and onto a small private road where it was seen at a range of only 20 yards by 3 people in a car. Obviously I went up there as fast as I could to talk to the witnesses. They described it as being black, slightly larger than an Alsatian, fairly low to the ground, having a very long tail with a curl at the end and moving in the typical cat’s slink. These would suggest (particularly the tail) that this was a leopard. I had a look around the area, but saw nothing to suggest that there was a cat in the area (well, this was by now 2 hours after the sighting, so no wonder).


Everything was quiet until Saturday, 3 days after the sighting. I discovered a young roe deer (≈15kg) that had been killed [one photo is attached]. Hair (not skin) had been taken off from large patches on its abdomen, revealing the pale skin beneath. The hair was lying all around the deer, either in little clumps or as single hairs. This was especially interesting, as the body was still warm. Actually, it was more than warm; it was pretty much normal skin temperature. It would seem that I had disturbed the killer from eating its meal by roaring down the track on the quad bike (I actually get pair to drive a quad all day!). Footprints were abound around the mud next to the kill (these later turned out to be dog; verified by Richard Freeman).


I did not expect to have a big cat sat about 5 minutes from my house killing our prized deer! I say prized, rather, the 3 deer who lived partly on the shooting ground’s land had become used to us in the workforce and were not too bothered about us being near them. Near that is, compared to normal deer who bolt at the meer sniff of you. After chatting to a few people, it appeared that the cat had been pushed through from the area that it used to be in by the local fox hunt who by chance had swept through its territory pushing the cat in front of it. When the hunt stopped just after reaching the shooting ground the cat carried on and set up temporary residence in the woods one KM from the shooting ground.
This takes us up to December, I’ll update again soon to bring this straight up to January. That is, if I’m not killed by my exams.

A new venture

So, here we have it, my first blog post. I guess I have to introduce myself first. I am a student working to obtain some decent A-levels so that he can go to Bristol University to do a degree in Zoology. I am involved in a number of disciplines within the zoological cover, including entomology, ichthyology, palaeontology and cryptozoology. The last one I guess is fairly obvious otherwise I wouldn’t be in the CFZ blogs page! Hopefully I will manage to keep on a zoological track as I witter incessantly about hunting big cats in Britain, writing a book and general musings about nature. I guess it’s time to get some sort of back story up and running...
