deer killed by fox not big cat at Woodchester

 
Posted by Picasa


Well that was a shame,the results from the DNA tests on the Woodchester(Glos.)deer carcases have come back with the most likely candidate being a fox.Not a trace of big cat DNA was found.Hats off though to our Gloucestshire colleages for having the guts to make public their intentions before the tests were even started,in this way the public were involved in the whole process from start to finish so gaining an insight into the processes albeit the many cul-de-sacs and dead endes that this big cat game produces.We live,we learn, as they say whoever "they" are.If the deer kids were killed by a big cat then peoples involvement along the way would of made people feel part of it.Still,it just goes to show just how hard it is to produce evidence of big cats and how that needs to backed up by other signifiers and not just be taken on it,s own.To be fair that hole in the neck is typical of some canid strikes and what it does show that foxes are a very resourceful predator,i did find a picture on the net of a supposed leopard kill of an antelope in Africa which had a large gaping wound on the side of it,s neck but this was the exception,generally speaking big cats such as leopards kill by throttling and this is the only deer killing method by big cats,whatever species they are,that i have come across here in Sussex.I was quite surprised to hear that a fox could pull down and kill a 35lb roe kid in fact i couldn,t see it happening at all until i remembered about fully grown in-lamb ewes being pulled down by supposedly packs of foxes up in Scotland during the very hard winters of the early 1960,s,mind you the hill foxes up there are a bit bigger than our ones.The trail camera pics i posted last month show a fox catching a squirrel,a very nippy customer indeed and various foxes have been known to specialise and become very expert in various predatory techniques,last year i watched a vixen bolt rabbits from buries for her 4 cubs on the downs near Lewes, a walk there the next day saw the team at the same caper again.It seems quite clear that the Woodchester carcases were the work of a rogue fox specialising in targeting roe young,most likely progressing up from the very young kids to the hefty,for a fox,35lb ones,foxes are well known to be the principle predator of 1 to 2 month old roe.A huge fox was shot last year weighing 28lb, a record i believe,not particularly fat just a massive animal but i don,t suspect such an animal was responsible for the deer killings,we will probably never know but it was more than likely just a normal fox which has specialised in taking down deer....

Big cats have been in Sussex for many years but it,s only since the late 1980,s that they have been encountered with any degree of frequency to give the impression that they are an established presence.Numbers of big cats have only until recently been able to of been quantified however they don,t seem to of increased much if at all in the last 5odd years,in addition to this the estimated home range of any one of these big cats does appear to be in the region of 6oo sq.km and their territory size doesn,t seem to of been reduced.There must be several factors involved in this such as the ever reducing size of hunting habitat due to development,disturbance of cover by increased recreational use leading to less prey numbers and suitable ground for themselves.A succession of hard winters may also be a reason nor can disease spread by the feral domestic cat population be ruled out however i am sure that the principal factor hindering the increase in the big cat population is down to foxes.Foxes are very numerous in most parts and have loose territories that they patrol vigorously hunting and foraging for what they can find,they are in direct competition for the same resources as big cats ,discounting deer(Woodchester deer kills aside)and can roam all of their area several times a week,they have to to prevent repeateed incursions from other foxes.When they have exhausted one supply they are highly adaptable and can change over to something else and even revert to eating earthworms which account for a very large proportion of the diet.Big cats on the other hand literally move in on differing fox territory visiting only a handful of times a year at best and the rabbits they are after,the fowl they are stalking,the voles they are poking for, etc.etc. has already been severely got at by the local foxes in all likelihood and made wise in the process.There are times of feast of course when there is enough for everyone such as the baby rabbit boom in early spring but it,s the times of famine,the hungry gap of febuary/march that dictate eventual numbers of big cats and this is when they can switch over and target,catch and kill their number one competition,the red fox...

In the autumn of 2010 i had been seeing a young roe doe with her first kid and they had a habit of lying up in the daytime amongst tall grasses right out in the open field,one october afternoon i saw a fox,not that big either,hassling the kid trying to have a go at it and very nearly did only for the doe to rush along to it stamping and kicking it,s hooves out forward,straight away the fox gave up and moved on.The young roe kid was still around the next day or 2 but after that dissapeared from the does side until a month later in november,the day before bonfire night,i found a small roe carcase,presumably the kid i had seen before with fox scat by it in the small copse next to the favoured roe lying up field.Presuming the doe had birthed in late may or june it would make it only around 3 months old but still at least twice the size of a fox.Strangely enough if i hadn,t seen the fox worrying the deer in the first place but then found the deer carcase i could of assumed that it might well of been the work of a big cat as one had been seen in the area at the time of death,the scat too was quite large for a fox but fox scat it certainly was.Well this was the largest roe that i had thought a fox would of been capable of pulling down until i simply Googled "fox kills deer"the other day and straight up came a report from New York state in America of a red fox killing a 35lb first year deer in someones garden.Not forgetting that American red foxes are the result of imports from England by hunting folk emigrating there a century or so back and so are of the same stock as our English ones this means that a red fox weighing around 12 to 15lb should be capable of ,in theory,actually killing a 35lb deer.News to me,but then they never cease to surprise me those most tenacious of beasts the fox......

Sheep are not eaten by big cats in Sussex

The Sussex big cats do not target either sheep or lambs.This statement has provoked much debate among the local big cat researchers and it,s fair to say i,ve had to defend these words quite vigorously.The principal point against these facts is that out of a commercial flock of say 6000 breeding ewes that would produce say around 11000 lambs,would,say,the sheperd/ess miss a few that were taken overnight with no trace and strat worrying what happened to them or would the sheer numbers involved mean that in all likelihood a dozen here or half a dozen there not be noticed at all.
Modern sheep farming in Sussex is a highly mobile operation with in reality all flocks are actually split up into hundreds of ewes spaced out wherever the lambing fields are with the stockmen actually doing rounds of many of these fields in a single day.Many rent the grazing and only put what each field or group of fields can handle.This means that they are more easily kept an eye on and believe it or not anything amiss is usually noted promptly.Fencelines are quad biked along as are bramble or scrub patches looking for fleece either stuck in the wire or on thorns that would be a telltale sign of predator attack.
Foxes do take lambs on occasion as do badgers however fox kills are easily noticed as they tend to go for orphaned or triplet new borns not yet acquanted with their surrogate ewes or the ones caught up in the said fences or brambles.In "08 i think it was we had a 2" fall of snow in april around lambing time on the downs and the resulting wind blown drifts "drowned" 50 or so new borns,the quick thaw revealed that the local foxes got wind of these easy meals with themselves cubs to feed and then went on to have a go at the lambs as they got a little older which is unusual as often foxes just go for the afterbirth.Foxes tend to drag a carcase a short way while they are eating it and the evidence of their kills is easy to notice as much fleece is lying around and the site tends to be messy.The messiest are the badgers though and these have the strentgh to drag the lambs into deep cover often squeezing then through the sheep netting.All the shepherds i know or have spoken to would notice any of these goings on and it would appear by what i,ve been told so far that lambs taken by either foxes or badgers would be well down on previous years with only a couple reporting any problems and neither of these involve big cats.At the South of England show next weeks i,ll have a chance to chat to a few others and find out more.In fact, like deer,lamb carcases are never carried very far away.Take the Telscombe lamb kills saga from last year where a big cat definitely had been killing the lambs,every carcase was found in the surrounding scrub and was consumed there,the bodys didn,t just mysteriously vanish and all were immediately noticed by the farmer.Even up to the 20 kilo lambs which are a heavy load for the bit bigger than a labrador big cat that was seen amongst the sheep at night with lamps to carry over the fences and it appeared that it had copied the badgers in pulling the bodies through the netting.I had never seen anything like it before which made the exception rather than the rule.
So,would a few lambs missing not be noticed occasionally by a particularly hard pressed farmer?Well,maybe for a short while in the uplands up north where say black faced sheep drop their young without much problem and little help from the sheperd but here too from what i,ve been told they are very much on the ball as their foxes really do take lambs on a regular basis but here in the more sheltered south the favoured meaty crosses can sometimes struggle to give birth and all available hands will be on deck to help.Every ewe is tagged and the numbers of lambs noted,this is rudimentary stockmanship to guage which are the best breeders and when they are moved off the lambing fields any and exact shortfall of numbers will be noticed.I checked this out last year with sheperds and found out that as usual all casualties were accounted for,of course i can,t speak to everyone but if anyone knows any different then please tell me?
In addition to this any flock that is continually harrased either at night or by day is extremely noticeable by their owner who will find out the cause pronto,it just so happens that like foxes big cats suss out potentially new hunting oppurtunities well before they go in for the kill so to speak and will be seen in the fields amongst the sheep at night before any lambing takes place,this so rarely happens i can count the occasions happening on one hand.
It is my opinion, weighted by all the available evidence,that on the very rare occasion for lambs to be taken by a big cat that firstly the evidence is plain to see and only when it has cubs to feed and for some reason the natural food like the rabbits has been denuded.There is no evidence to the contrary,if there was then i think i would be the first to say it.A healthy scepticism and constant questioning of the facts helps us all understand big cat behaviour that much better and to analyse what we know or think we know already but there is drawing the line between supposition and fact by examining the evidence.It is often supposed that a sheep carcase is found by a member of the public and just because a big cat has been seen in the area 1 and 1 makes 5 in that the conclusion will be that a big cat has killed the said sheep,it then gets reported to the press and supposition becomes fact overnight without any analysis of the carcase,investigation of the scene or any of the photos,if any,made available for public scrutiny.When on the odd occasion it does happen for real it all gets blown out of proportion.
Looking for evidence of big cats being anywhere beyond the usual witness statements is extremely difficult and very trying on the patience as very little if any is found when we know full well a big cat has been very active in an area,it can be tempting when looking for clues to jump to conclusions in our haste for some sort of evidence but looking around sheep fields for sheep carcases will only prove in the long run ,i,m sure,that the title of this piece is the normal current of affairs........
