Should the Raven (Corvus corax) be added to the general license?

This week saw the launch of a new petition, one aiming to have the Common Raven (Corvus corax) added to the general license – a move that would allow landowners to control (by lethal means) ravens in the same manner as species such as Carrion Crow, Magpie and Jay. This is a move that will surely anger many conservationists, resulting in the deaths of a great deal of these currently protected corvids. It is however a move many farmers feel is necessary to protect livestock and thus, their income. It is an interesting topic and one that I have tried to view without sentiment – a difficult task for someone, like me, who harbours a soft spot for these birds. Before giving my opinion on the matter, a summary of the argument (from both sides) is surely in order..

The Problem

Ravens, by far our most imposing corvid are known to pose a direct threat to livestock, particularly in upland areas. This is particularly true when it comes to sheep farming – something made apparent by the graphic and, ultimately rather horrible images that surfaced recently of new born lambs subject to depredation. A few of these images are shown below for reference though it should be noted that they are not nice to look at.

Farmers claim that due to the ravens protected status and subsequent population increases, that attacks of livestock are becoming more common – a logical assumption and one that is likely true. Attacks by ravens on sheep are not pleasant, the birds targeting various bodily orifices and often, not killing their prey outright. Something that no doubt results in a great deal of anguish for farmers forced to euthanize their stock upon discovery. This has lead many to criticize the protected status of the birds. Among these, Bert Burnett of the Scottish Gamekeepers Association whom stresses not just the threat posed to livestock by increasing raven numbers, but also to wildlife, most notably breeding wading birds.

The impact of ravens on livestock are hard to dispute and the situation is openly acknowledged by Scottish Natural Heritage (SNH) whom to date have issued licenses for the selective killing of ravens in areas where they pose a problem to rural interests. These licenses have been critisized by farmers however who feel that killing “a few” birds is not sufficient to protect their stock, a recent example being used to bolster support for the petition. Here a flock of 30 ravens contributed to the deaths of a number sheep (both lambs and ewes) and as such a license to control the birds was applied for. SNH however granted permission for only two ravens to be removed – a move that many feel falls short of the mark when it comes to protecting “at risk” livestock.

SNH have responded to the current petition, promising to take the situation into consideration during their upcoming review of general licenses, their response to the petition in question shown below:

we are aware of this petition and of the interest in adding Ravens to the birds which may be killed under the General licence. The list of species’ which can be controlled in this way is something which we keep under regular review. We are due to hold a consultation on General Licences later this year and following the outcome of that process, we will consider what changes, if any, are required for the general licences.”

The idea of adding ravens to the general license has however unsettled some and a number of groups have voiced their opposition to the notion, among these the RSPB.

Opposition

The RSPB, while acknowledging the “distressing situation” has openly opposed the move to add ravens to the general license. Their initial response to the aforementioned petition going as follows:

It’s completely understandable why this would be a distressing situation, however SNH does regularly issue licences to farmers to kill Ravens for livestock protection. We think it is therefor completely unnecessary to put Raven on the General Licence, which would result in poorly regulated, unrestricted killing of Ravens. It should be remembered that the Ravens in the East of Scotland are only now recovering from historical eradication and would be once again vulnerable to local extinction if SNH allowed a free-for-all on these birds. Hope that helps to answer your question.

As ever, by opposing the notion, RSPB have prompted a backlash from those in favour of control measures – some fearful that the organisation could influence the decision on behalf of SNH. It should however be noted that many conservationist share the RSPB’s stance pointing out that moving ewes indoors to lamb would solve the problem without the need for lethal control. Highlighting that by lambing indoors and thus removing a potential food source for ravens that localised high densities would even out – ravens dispersing (or dying) due to a lack of food in the area. The latter statement has been disputed by those in favour of increased control – stating that moving entire flocks indoors during lambing season is both unrealistic and detrimental to the welfare of the sheep themselves. Large numbers of sheep in close quarters allowing disease to spread and, ultimately, cause the deaths of more animals.


Ravens in the UK

At present, ravens are strictly protected under UK law, the entire British population estimated at 7,400 pairs, a grand total of 14,800 individuals – a dramatic increase from decades past where the population crashed due to unchecked persecution. Though this number may appear healthy, it represents only a fraction of the population that the UK “could hold” and indeed, ravens remain scarce in some areas. As the RSPB point out, ravens are still recovering and consolidating their range in certain areas, including the East of Scotland where many issues have occurred. Those in favour of culls have however stated that these estimates are inaccurate and that far more ravens persist in the UK at present. Though the species is gradually colonizing lowland areas, the majority of the raven population remains centered on upland areas – something that may lead to assumptions that the species is “abundant” though, given the turbulent history of C.corax it is far more likely that such numbers represent a natural equilibrium – in essence, what raven populations should be like absent the persecution that took place in decades past.

My two cents’ worth

Until figures are produced with a certain degree of accuracy verifying claims that the Raven population is far higher than estimated I cannot support the addition of C.corax to the general license. This is not born of sentiment, or indeed out of opposition for culls or farmers taking action to protect their stock – I have no problem with the current workings of the general license. No, I cannot condone the widespread killing of ravens due to their conservation status. They are, after all, still recovering from the last time humans pushed them towards the brink. In my opinion, allowing the unregulated killing of ravens would render the recent gains of this species obsolete – effectively setting the population back a century or so.

Despite opposing this move however I should stress that I in no way oppose the notion that farmers should be able to protect their stock (and thus their livelihoods). I have stated time and time again the need to be pragmatic when it comes to both protected species and conservation and do feel their is leeway for SNH to possibly build on existing licensing. Obviously all control measures must be highly regulated – the number of birds removed recorded and analysed so not to impact upon the over all population but yes, if SNH were to allow the killing of more ravens in exceptional, problem circumstances, I would not protest. The needs of people must after all be met and while ravens are admittedly rather charismatic and thus inspire a great deal of devotion from nature lovers, it may be possible to strike a balance between the needs of both man and beast. Allowing farmers to protect their interests without declaring “open season” on the species.

I do agree that other measures could be deployed to protect sheep from raven depredation – moving stock indoors during lambing is certainly an option in some locations. I am however not naive enough to believe this is an option in all localities and thus accept that some ravens will need to be killed. Something that animal welfare groups and “compassionate” conservationists will no doubt dispute. Protecting each and every individual of a species, at all costs, is a noble notion but one I do not feel is very realistic.  If raven populations remain stable – a likely prospect under the current system, even with an increase in licensing, I stand content. Of course, it would be nice to see other measures given an increased focus prior to the implementation of lethal control – something SNH must surely aid with.

    On Boxing Day, upon a pleasant though wet and muddy walk down the Salt Line in Cheshire, I heard and then saw a Raven. Not a common occurrence here in East Cheshire. It made my day.

    Now two winters ago, whilst working in Bedfordshire, I became rather fascinated by a pair of Raven that I got to know on my walk to work each morning. My blogs at the time confirm my fascination, verging on obsession!

    Whilst working with land owners and managers last year, I well and truly got to hear about how ‘they’ felt about Raven. Some people are born detesting corvids. I have no other explanation for the absolute irrational revulsion that they hold for these intelligent, inquisitive birds. They really would kill them all given the chance. I do understand – a flock of a thousand Rooks really could ruin your crop. And all corvids are opportunistic, taking bird eggs and small chicks given the chance. And yes, maybe Raven kill the odd lamb. That’s nature. But the hatred was more than that. Ingrained.

    Wessex is home to good populations of Raven. The numbers of which I’ve never seen the like before. Hearing and seeing them was a wonder to me. And yet I was regularly asked if we couldn’t help to change policy, so that they could exterminate them. I do suppose that if you see a lot of something on a daily basis, it may be hard to appreciate that they don’t exist anywhere else.

    Last year I came across them so often that I eventually got over my obsession, and became rather blaze about them! “Oh, there’s another twelve Ravens, I do hope they don’t disturb the Stone-curlew!”. One can have too much of a good thing. But get rid? Absolutely not. Raven are making a wonderful come back after all those years of persecution. Welcome to East Cheshire, you glorious intelligent silver birds.

    The only problem with James Common’s article is a very fundamental one. There has been very little research carried out to establish whether the premise is true. As a lifelong birdwatcher I had always been sceptical of claims made by local farmers and gamekeepers that Ravens attack and kill healthy lambs, because I had never seen any evidence to that effect, and neither have any of my birdwatching colleagues. Because of this, I decided to investigate and carried out an intensive study over three lambing seasons near my home – typical Raven habitat with moorland-dominated uplands and surrounded by mixed countryside. My study population consisted of twelve nesting pairs and a non-breeding flock of around 100 birds. The result was that despite observing the birds’ behaviour in intimate detail (a cumulative 80 hours watching them in fields of lambing ewes), I recorded absolutely no evidence that any of the Ravens ever harmed a healthy lamb. Photographs like those attached to the above article are very familiar to me, because it is normal for Ravens to consume lambs which were stillborn or died shortly after being born. Sheep and other animal carrion makes up an important part of the Raven’s diet. The Ravens will occasionally commence feeding before the animal is dead, but as far as I’ve been able to determine, only when a lamb is moribund. That’s nature, whether we like it or not. It appears to be a popular countryman’s myth that Ravens attack and kill healthy lambs, but in reality it’s as likely as eagles carrying off human babies. I truly found them to be the gentle giants of the crow family, and my observations would have made excellent viewing on Springwatch. Unfortunately the myths about Ravens have been repeated mantra-like so often that even the RSPB seems to believe them. In the meantime I am writing up my research for publication, but independent research is required to establish the truth, before any decision is made about the Raven’s future protection status.
