A marsh tit at large


It seems an age since I returned to the UK from Asia. It seems a different marsh tit who was there. But there are photographs to show that I was there and from time to time my lovely clients send them to me. The first, of snow ninjas in the Rumbak Valley (the things you do to stay warm while looking for snow leopards), is by Richard Hurrell. The rest, from Tadoba and Kanha in Central India, are by Graham and Tina Nuthall. As always I'm in shorts in Central India and quite often I'm barefoot, my spindly legs waving from the side of the gypsy. When wearing sandals they are dangling, barely strapped from my feet. Some things never change.

Thanks to Richard, Tina, Graham and all my Asia clients in 2015, for their photos and for their humorous good company watching big cats in India.

Saving more species


Written on 31st May, published with the agreement of the press team at RZSS and other interested parties


My conversation with Doug Richardson of RZSS Highland Wildlife Park did not restrict itself to the plight of the Scottish wildcat. Far from it. The park is home to four further species of wild cat, with a fifth to arrive in the near future. Here therefore are more thoughts which Doug and I ping-ponged between ourselves on Sunday morning.


Amur tiger Panthera tigris altaica

The Amur tiger is the largest subspecies of the world's largest cat and is restricted to the southern far east of Russia and, historically, bordering areas of China. It is characterised by its light orange coat, dense fur, rather weak black stripes and extensive areas of white in its cheeks and throat. It is magnificent and on Sunday I spent far too long cooing over Highland Wildlife Park's three cats.

As magnificent as it is, the Amur tiger is also desperately threatened. Until very recently it was essentially extinct in China and well on its way to extinction in Russia. Still today, though WWF claims this week that there are now 540 wild Amur tigers, this subspecies is critically endangered. Some believe this figure to be inflated and one source reports that there may be only 40 reproductive individuals in the wild population. And every single individual that has ever been radio-collared, Doug says, has been poached in the end. Every one.

Happily, if there is any happiness in this situation, the captive population is known to be genetically pure, a far better situation than pertains with the Scottish wildcat. At Highland Wildlife Park there are currently three Amur tigers, an adult pair and their male youngster born in 2013. He will soon move to form half of a new breeding pair at a zoo in Germany, just as a sibling from the same litter recently went to Switzerland. The adults live in a large birch-scrub enclosure which hints at the taiga home of the species in Amur.

Doug has such experience with cats in captivity that he is husbandry advisor on the Europe-wide breeding programmes for both Amur and Sumatran tigers. It is with his eyes on Amur that he passionately argues for the need to keep this subspecies in captivity in the Scottish Highlands. He feels, and his argument is borne out by reintroductions across the world, that without the husbandry skills gained through breeding an animal in captivity we cannot hope to return it to its natural environment. Critically, also, in the case of large, severely threatened carnivores, without captive populations there can quite simply not be enough individuals, or enough genetic diversity, to restitute a healthy wild population in the future. Already, Doug says, there are genetic dynasties of the Amur tiger in captivity, which are known to have disappeared in the wild.

It is a sad world indeed in which we talk in these terms. But it is the world we inhabit.

Pallas's cat Otocolobus manul

I've always thought it rather unfair that Pallas has so many marvellous animals named after him: a powerful eagle, the most dramatic gull, the most delicate and enchanting leaf-warbler, the snazziest grasshopper warbler, the most evocative sandgrouse. However, where cats are concerned Pallas drew, if not the short straw, the strangest of straws. Pallas's cat is weird.

Highland Wildlife Park has an excellent record of breeding and raising Pallas's cats, a species which, Doug tells me, can be difficult to rear to adulthood on account of its susceptibility to toxoplasmosis. Last year, thanks to veterinary advances, Highland Wildlife Park raised an exceptional six Pallas's kittens.

The Royal Zoological Society of Scotland coordinates the European breeding programme and international studbook for Pallas's cat. It also supports research into Pallas's cats in their wild range, funding camera-trapping campaigns in Mongolia, Iran, Nepal and Kazakhstan. The intention is to map the species' distribution with greater accuracy and to explore the veracity of the cat's supposed subspecies. More information on RZSS's work with Pallas's cats may be found here.


The Pallas's cats are currently off exhibit,
so I took this as a surrogate.


Northern lynx Lynx lynx lynx

The park has recently, quite strategically, changed from keeping Carpathian lynxes to keeping northern lynxes, aquiring one adult of Swedish origin and another of Latvian. Doug is quite clear on the rationale behind this. Until a few hundred years ago when we extinguished the lynx in the UK, it would have been northern lynx which inhabited our island. It is therefore, Doug argues, important for a facility within a region in which lynx might one day be reintroduced to maintain the correct subspecies, principally for local stakeholders to be able to see the living animal in the flesh.

It is also crucially important for animals which might one day be released to have been raised in a way which minimises their likelihood of coming into conflict with humans and their livestock; and for the local institutions involved to build good relationships over time with those whose livelihoods could in theory be affected. The reintroduction of a large carnivore is not a question of opening cage doors. It is a question of people, institutions, stakeholders in a landscape working together over decades for the good of wild species and their wildnerness.

Doug is not a man to shy from such challenges. As he talks, from his position of immense knowledge and experience, you can feel him mentally rolling up his sleeves to take on a tough gig. For now his lynxes are breeding successfully at the park, with two new kittens born last week, and they are proving very popular with visitors.

How I'd hoped it would work out



Amur leopard Panthera pardus orientalis

It might seem obvious that a zoo should prominently display charismatic animals in its collection in order to draw in the crowds. Think pandas at Edinburgh Zoo. It might seem obvious, yes, but that's not what RZSS and Doug have in mind for Amur leopards.

In July this year Highland Wildlife Park begins construction of a large enclosure for Amur leopards in an area of birch and juniper scrub at the top of the park. It will never be seen by visitors. Its aim, Doug explains, is not to display a breeding pair of Amur leopards to the public, but to welcome established breeding pairs from other instituions (obviating the need for the complex and potentially dangerous process of introducing a new pair to one another) and, in a very naturalistic enclosure, encourage them to raise young which are wild enough to go back to the wild.

The wild population of Amur leopards has reached critical levels, with some experts suggesting that fewer than twenty individuals remain, and no-one believing there are more than fifty. Russian authorities plan to create a second, reintroduced population, within the historic range of the cat but outside its current wild range. Doug and his remarkable facility in the birchwoods would provide cubs for this project, to order, according to the new population's genetic needs. Established pairs from the captive breeding programme would visit RZSS's visionary Amur leopardarium in turn and their cubs would go straight back to the Russian far east, without losing their innate fear of humans. Via a huge soft-release enclosure in the taiga they would then join this new population of the subspecies in the wild.

Or almost of the subspecies. The trouble with Amur leopards in captivity is that one of the founders of the captive population, a female known as Founder 2, is now known not to have been an Amur leopard at all. As a result the captive population is around 12% impure. So the Amur leopard in captivity (and therefore the founder stock of Russia's proposed new wild population) is faced by the same problem as the Scottish wildcat. It is not exactly what it says on the tin. The romantic end of the conservation community may well decry the Russian government's iniative, believing it better to lose the Amur leopard altogether than to dilute it with non-local genes.

Certainly if nothing is done we shall soon lose the wild Amur leopard altogether. So, at the pragmatic end of the community, Doug would say that it is better to have an animal which is genetically closely similar to the Amur leopard than no animal at all. A hardline ecologist would no doubt say the same, as an ecosystem with a top predator, whether it be the pure original genetic form of the top predator or not, is a healthier ecosystem than one without.

Philosophy aside, Doug and his team will soon commence construction of a superb new enclosure for Amur leopards at Highland Wildlife Park. Uniquely it will be for leopards and not for humans; visitors will observe its inhabitants only via remote cameras. What happens to the leopard kits born in this enclosure may revolutionise our understanding of big cats in zoos.


Snow leopard Panthera uncia

Construction is also underway of a snow leopard enclosure in the heart of the Highland Wildlife Park. This large, open-topped enclosure includes a small rock face and a patch of light birch scrub. It abuts a paddock housing Turkmenian markhor and on occasion, while the snow leopards are inside holding pens, the markhor will graze the snow leopards' outdoor area, enriching the scent and sense experience of the landscape for both species.

In collaboration with Norden's Ark in Sweden, the snow leopard project at Highland Wildlife Park will support conservation of wild snow leopards led by the Snow Leopard Trust.

Saving species


Written on 31st May, published with the agreement of the press team at RZSS and other interested parties


I have been stagnant these past two weeks, my mind and body rebelling against the great pile of jobs which has built up during almost four months of travel. Over these two weeks I could-have-should-have-would-have prepared better for this trip to Scotland, read more, written more here (I still have a mountain of ideas from Asia), and generally been a more assiduous marsh tit. Instead my body and mind have been in rebellion.

Today, like a proverbial new broom, Doug Richardson swept into my life and filled my mind with ideas, with questions, and with excitement for this second, British stage of my Big Cat Quest. Doug is Head of Living Collections at the Royal Zoological Society of Scotland's Highland Wildlife Park. And well he should be. He has spent his working life in many of the world's finest zoos and is full of zeal for the role that responsible zoos can play in wildlife conservation on our pained and compromised planet.

Doug had kindly agreed to meet me today to talk about cats at the Highland Wildlife Park and for two hours this morning that's just what we did.

Our conversation was wide-ranging (geographically and intellectually), tangential (at times almost fractal), impassioned, and frequently expletive. Often when listening to zoo folk in the past I've been disappointed by their apparent lack of knowledge of wildlife where it belongs: in the wild. Not so with Doug. His range of experience and reference is enormous, embracing distant continents and diverse animal groups with ease. He cites obscure subspecies of cat and best practice for raising arctic ducks in captivity without pausing for breath, and has always a dark spark of humour in his eye. Here is a man who is passionate about wildlife and its conservation.

It so happens that his contribution to its conservation is in captivity.

We spoke of so many things that it would be impossible to list them all here. I shall summarise some of what we said of cats, species by species, mog by mottled mog, beginning (in this post) with our native wildcat.


Wildcat Felis silvestris grampia

Among the most threatened vertebrates in the UK is the wildcat. It is known as the Scottish wildcat by historic accident, for everywhere else in the UK we killed it off. It survived, by accident, only in the remotest and least tamed reaches of Scotland.

A second peril compounds this range restriction today: hybridisation with domestic cats. This has been recognised as a problem for some decades and as an acute problem for several years but in Doug's no-nonsense words, 'We kinda faffed about.'

Today no-one knows whether any pure wildcats remain in the UK for none has yet been found. I learn from Doug that this includes the captive population: of some 35 wildcats of Scottish origin in captivity he estimates that 20% are 'worth breeding from.' Genetic tests to identify these animals are ongoing.

Genetic tests are also applied, where they can be found and caught, to cats in the wild. As part of the recovery programme coordinated by Scottish Natural Heritage there will be a widespread campaign of trapping, led by RZSS, to establish where there are cats, how pure they are and (this is where controversy enters the equation) which few should be brought into captivity as the founders of a new, representative breeding population.

Hackles will doubtless have risen at that last statement. Bring them into captivity? It shouldn't be allowed! Why would SNH take away our wildest animal's wildness? The why of it is tragically easy to understand. For a very long time there have been domestic cats in the range of the wildcat. All domestic cats, Doug says, are descended from just six founder females of Middle Eastern origin. Middle Eastern wildcats, and their domestic inheritors, are genetically very distinct from European ones but interbreed freely with them and produce fertile offspring. This is precisely what they have been doing for generations, with the result that there are possibly no pure wildcats left in Scotland at all, not to mention the rest of Europe.

Two measures of purity are used to assess wildcats which are caught. The first is phenotypic, based on characteristics of pelage which are known markers of Scottish wildcats, and is carried out by Andrew Kitchener of the National Museums of Scotland. The second is genetic and is carried out by RZSS. The benchmark for what a pure Scottish wildcat ought to look like, and what it should be genetically, has been taken from museum skins and mounted specimens of the nineteenth century. On account of the lack of 100% pure animals identified thus far in the captive and wild populations, a lower genetic threshold must be applied regarding what is functionally a wildcat.

The fundamental problem is that even those wild animals deemed functional wildcats are still surrounded by feral cats and less pure hybrids. It is for this reason that Scottish Natural Heritage, the Royal Zoological Society of Scotland, Doug and many colleagues have accepted that in the short term the only solution for the wildcat is to take more animals into captivity, and there maintain and build a population of animals which genetically and phenotypically best represent the Scottish wildcat. Cats left to their own devices in the wild, through most of Scotland, will soon be wholly swamped by the genes of feral cats and an irreplaceable part of our island's biodiversity will be lost, through genetic attrition, forever.

RZSS and Highland Wildlife Park's role in this has several elements. The simplest (though by no means logistically simple) is that half-a-dozen relatively pure Scottish wilcats are kept at the park and are bred (I saw some adorable kittens today) under the studbook kept by the Aspinall Foundation at Port Lympne in Kent. Secondly through this same work Doug's team contributes to understanding of wildcat husbandry, and this will be critical as the species' conservation becomes, in the short term, more dependent on captive management. Such management of wildcats at the Highland Wildlife Park forms part of Scottish Wildcat Action (new website to be launched soon), a multidisciplinary approach to the conservation of the cat involving captive breeding, threat reduction in the wild in six priority areas of Scotland and extensive monitoring to assess the effectiveness of measures being taken.

In addition, the Highland Wildlife Park can act as a quarantine facility for animals which come into captivity, either through chance (such as orphan kittens) or as a result of deliberate trapping, and can facilitate the incorporation of animals of wild origin into the captive population. Critically the park has large areas which are off exhibit and in which genuinely wild animals can be kept away from the gaze of the public, safe from habituation to humans. It is very clear in the minds of all involved that wildcats, however much intervention is needed, must be kept wild.

It is the word wild and our romantic understanding of it that cause most controversy. Those of us who believe in the conservation of wildlife still hanker after a wilderness in which wildlife looks after itself. It offends us to think that wildlife should be brought into captivity in order to preserve it. The wild should be wild! When recently Craig Packer, director of the Serengeti Lion Project, and arguably the world's greatest authority on lions in Africa, declared on the basis of decades of research that the only way to save lions in the Serengeti was to fence this massive park he was vilified. Despite clear evidence that the lion is declining catastophically across Africa and that conflict with humans in the Serengeti is reaching a critical level, he was shouted down. There were even voices from the conservation community which argued that it would be better to have no Serengeti than a fenced Serengeti.

Doug has no time for such sentimentality (and nor in fact do I). My own response is to ask whether those who would rather have no Serengeti have been there, whether they have seen the phenomenal spectacle of its migrating herds and their attendant predators. To lose such a treasure by taking a holier-than-thou attitude towards conservation would be unforgivable.

Doug believes that the same applies to the wildcat in Scotland. The evidence that hybridisation is destroying the species apace is unassailable. Better therefore to be the custodians of some of the purest cats in captivity for a generation or two, until a solution to hybridisation can be found across wild landscapes, than to preside inactive over the extinction of this remnant of our primeval wildness.


If it were only that easy









My customary selfie,
this time with a Scottish wildcat

In the end, after a week of searching, I did manage to see a largely pure wildcat in the wild. The story of the encounter may be found here.

The wild within


As I walked from my bus into Norwich yesterday a buzzard drifted high towards the spire. I knew, from three months spent in the company of the cathedral's peregrines last spring, what would happen. As distant dots both adults scrambled into the airspace above their spire (and on it their three just-fledged chicks). As almost always, the female sent the male up to the buzzard, to drive it from her patch of sky.

This was my first sight of the Norwich peregrines this year (I've been abroad for almost all of 2015). I have missed them; and as much as them I have missed the fantastic team of staff and volunteers who watch the peregrines, who work with cathedral staff, and who - crucially - explain the lives of the birds to the public. Many thousands of people visit the peregrines each spring, or watch them from home on the Hawk and Owl Trust's webcam. For some, these breathtaking birds are a first point of contact with the natural world, and a relationship with it, a first glimpse of the wild we all carry within.



Norwich Cathedral peregrine dreamteam:
Mike, Julie, Becky and Maureen


For my friend Mike, the peregrines have been just such. Gripped by their lives on the spire the year before, last year, while I was helping to run the team, he joined us. Mike is not a man of half measures. If he does something, he does it well. He hurls himself at life with commitment, with verve, with talent and with a filthy sense of humour. The peregrines were no different and in no time a new naturalist was unfolding before us, a naturalist enchanted by everything around him, seeing the wild for the first time, hearing birdsong - really hearing it - anew. I have been privileged, at times, to share with Mike a new bird for him; and while I have been away he's kept me abreast of the wonders which have flown on brave wings into his life.

I visited the peregrines yesterday to see the birds during fledging week - always the most exciting - and to see the wonderful people who watch them. Some of my favourite peregrineers were on duty; so our morning sped by in talk of their lives and those of the birds, in watching a collared dove foodpass and the anger of the female at a herring gull who came too close (it won't be making that mistake again). Afterwards, having not caught up in all the months I've been away, Mike and I had lunch and talked, of birds and other beasts, in the sun.

There was time before my bus left for home so Mike stole me into the Castle Museum. To step inside this building, a Norman keep wrapped in Victorian pretension, is to step into my childhood. I knew at once what I wanted to see: the tiger. It was doubtless the first I ever saw, long before I ever dreamed I could see one in the wild. When I was a child there was a button on the side of its case which, when pressed, made the tiger roar. To my small child self this was thrilling.

The button is no longer there. The tiger no longer roars. The cat is there though and, on a day spent watching peregrines inspire people to inspire people about peregrines, this faded mockery of a tiger caused me to reflect on our relationships with the wild.

To the people of George V's Britain (whose king shot the Castle Museum tiger), a tiger in a case meant, I suspect, dominion over the wild, the bringing of order (British order, of course) to a wild, dangerous world. When George shot this tiger there were probably more than 50,000 tigers in India, ranging through vast areas of genuinely untamed forest. Injured tigers regularly killed people (a casual look at Jim Corbett's books is enough to confirm this) and rural people lived in deep fear. Britain's job, the king's job, was to suppress the wildness, to bring order where savagery prevailed. In killing a tiger, probably many tigers, the king confirmed his fitness for the job.




The Castle Museum's lions,
like the tiger still faded and old, still beautiful


Near the tiger there is a clever case, one of several on a theme of Victorian naturalists and their taxidermic relationship with nature, in which all of the specimens stem from Bostock and Wombwell's Menagerie. The skins are frightful - the leopard's face twisted into a hideous grimace - but they represent a past relationship with nature in which the wonders of the wild world were being discovered and brought home for the edification of the public (and the filling of menagerie-owners' pockets). I mused on what went through the minds and hearts of Victorian people on visiting a travelling menagerie. For many, I suspect, although the wild was not yet something to be preserved, seeing these hapless creatures was as inspiring as pressing the button on the tiger's case for my child self, or seeing a peregrine through a telescope (provided by Viking Optical, I should add) for a child today.

In the next gallery are hundreds of ill-starred birds collected by Victorian naturalists in the days in which ornithology was practised with a gun. Some, like a drake Steller's eider, are the single specimens of their kind ever to have been seen - and killed - in Norfolk. Others, like great bustards and (in the gallery of Norfolk dioramas) the otter, represent species which in modern times have been driven from our county. The otter was long persecuted here but finally extinguished from Norfolk (or all but extinguished) by pollution. Happily today it has returned in force, thanks in no small measure to the tireless work of the Otter Trust (rest in peace Jean and Philip). The great bustard was wantonly hunted from our East Anglian brecks. All that remains of it today is feather and skin and dust behind glass.








It is easy to judge these Victorian and early twentieth century attitudes to nature and animals: to censure, to condemn. It is equally important to reflect on or own attitudes and to remember the world in which we ourselves live, to which we contribute. Ours is a world in which dolphins are beaten to death in Japan and elsewhere; in which seal cubs are clubbed in developed world nations; in which your biscuits and chocolate contain palm oil which - directly - condemns orangutans and thousands of other species to death in felled forests; in which dogs are boiled alive in Yulin; in which raptors are trapped and poisoned and eggs are thieved in my Norfolk; in which the British government licenses the slaying of badgers and the destruction of buzzard nests, against all scientific evidence and advice, as a sop to its political cronies.

It is hard, in such a world, to stare into the glass eyes of a tiger and righteously condemn the attitudes towards nature of Victorians or English kings. The killing continues today; and, worse, the destruction of wild space is nearing its endgame, in the UK and across the globe. 

If we are to arrest it, if sense is ever to be bashed into the skulls of our ignorant, self-serving politicians (a red kite flew over my desk just now as I looked up to find the next phrase), if our children are to live in a world full of wild wonders, we need more Mikes. We need more prophets for nature, more moments in which children stare in awe at peregrines, or ladybirds, or woodlice (that one's for you Julie), or red kites. We need a revolution in the way we see the wild. The wild we all carry within.

Walking home from my bus, by the river I saw the death-blotched stems of hemlock and the dusty perfection of the flowers of mallow and I touched it: I touched the wild within.
