There’s More to a Raccoon Than a Davey Crockett Hat.

A Scottish wildlife organisation recently took a picture that might help save the planet – well, the Highlands of Scotland at least. It was on one of those automatic cameras used to monitor animals – and triggered on 17th March 2016 by a Procyon lotor – that’s a raccoon for those of us who don’t have the Latin – standing on it’s hind feet it looked as if it was feeding on some form of bait attached to a post: www.bbc.com/news/uk-scotland-highlands-islands-35942952     The image is technically limited and in contrasty black and white, but there is no doubting this is a raccoon. Baiting certainly works when it comes to attracting raccoons to cameras, but this shouldn’t be possible in the U.K. where they are not supposed to be, and catching one on camera is a real surprise when what you’re really expecting to see is a badger.

If you've seen a raccoon in the U.K. and don't get a picture... they'll tell you it is one of these...
If you seen a raccoon in the U.K. and you don’t get a picture… they’ll tell you that you saw one of these.

Failing a deliberate release, this Highland raccoon must have escaped from captivity, but that’s not exactly an environmental disaster, providing it’s not a pregnant female, or has the opportunity to meet up with a raccoon of the opposite sex… And what are the chances of that? Well, surprisingly good it seems, because a week earlier, on the 11th March, a raccoon was recorded on video just thirty miles away. The same raccoon perhaps? Well possibly, but that’s a bit of a hike for a raccoon in just a week; although when food is in short supply a healthy animal might range that distance, especially if it is a recent roaming escapee that has not yet found a favourable place to set up home. If it turns out there are two raccoons however, this could be the start of a much bigger problem.

I saw my first raccoon as a child – it was perched upon Davey Crockett’s head in a mid 1950s movie that made the most famous backwoodsman of all time a huge box office success in Britain – there was also a popular song that kept ‘The King of the Wild Frontier’ popular for a time – although I’m not sure how long – when you’re small things seem to go on forever. It lasted until the Lone Ranger and Tonto showed up on our T.V. screens to replace him. And surprisingly the Lone Ranger would continue with Crockett’s raccoon theme. More than half a century separated the two characters (and quite bit of fiction);  the raccoon hat had been replaced by a white stetson, with the raccoon identity slipping down onto the rangers face in the form of a raccoon mask – this along with an outfit rather too tight for general ‘lone ranging’ comfort, made the character somewhat laughable even to a child. It seemed that back in the old days whether, ‘way down South’ or out there in ‘the wild west’ you were never far from a raccoon, or at least a reference to one, and today this remains pretty much the case right across North America and there is a suggestion that in some states there are more raccoons around today than there were during the 19th Century when fur trapping was hugely consequential.

Raccoons are generalists: if they can find food, they will usually adapt to their surroundings and live almost anywhere. In their native land they avoid only the extreme cold of the frozen north and have managed to become one of the most successful mammals ever to have lived on the continent. In urban situations they have become equally successful, and often considered pests because of their habit of competing with humans.

I must admit, I don’t feel too much competition from the large individual that walks the fence-line around our garden. My family and I live in the Vancouver area of British Columbia where raccoons are commonplace – and not only is this individual a real beauty, it is also one of the largest racoons I have ever seen. Certainly in the northwest racoons can grow to about as big as this species will get. Further south where winters are warmer and summers hotter – in Florida and Mexico for example – a large body mass isn’t so important for retaining body heat and individuals are usually smaller.

Raccoons are mostly active during the night and our local animals will occasionally dig up the garden for grubs, but I don’t mind that. My habit of leaving the garage door open will have to stop though.  I accidentally shut a domestic cat into my garage one night when living in the U.K. – the cat wasn’t bothered, and apart from a slight smell of cat the garage was fine, the same thing happened with an owl when living in New Zealand – again no problem – although the cat smell was replaced by a pile of poo under the roost were the bird had chosen to spend the night. All well and good, but if I accidentally shut a raccoon into my garage overnight in Canada, I might just as well opened up the place up to a marauding bear.

Not the best of pictures - taken by a sympathetic observer who picked up my stills camera and grabbed this shot. This was probably my first attempt at filming raccoons. The two youngsters started off infront of the camera, but attracted by the sparkle of small bits and pieces in my camera case they quickly became less than ideal subjects. I had almost no recollection of this event until I discovered the old picture, obviously my subconcious had blotted out this wildly unsuccessful raccoon filming encounter.
Maybe not the best of pictures – taken many years ago by a sympathetic observer who picked up my stills camera and grabbed this shot as I wrestled with a couple of raccoons. The two youngsters started off infront of the camera, but attracted by the sparkle of the small bits and pieces in my camera case, they quickly became less than ideal subjects. I had no recollection of the event until I recently re-discovered this photo –  obviously my subconscious had blotted out my first and most wildly unsuccessful raccoon filming encounter, somewhere in Vermont.

I loved the suggestion from a spokesman for the attempted capture of the photogenic Scottish raccoon, that, if it could be achieved without personal risk, it would be great if somebody simply contained the creature in a shed or outbuilding. Now, containing a raccoon is  a novel idea – but the last shed I walked through that might adequately ‘contain’ a raccoon was on the island of Alcatraz – maybe Scottish sheds are a cut above the sheds I got used to when living in the South of England as a child; back then you had to turf the wildlife out before you could put the garden tools away; and the door was always left open during the summer months because robins were busy rearing young in an old teapot on a shelf at the back.

A spokesman also said that their organisation had set a humane trap to catch the Highland raccoon…  but there had been no sign of it yet, and that’s not a huge surprise. All too frequently raccoons are caught and held by unpleasant limb holding traps, but getting a raccoon secure in an humane alternative isn’t quite so easy: if you don’t capture your raccoon first time around you may not get a second chance – raccoons clearly didn’t spread across a whole continent because they were stupid.

Over the years I’ve photographed, filmed and videod raccoons in many different situations, both captive and wild and there was rarely a moment when they weren’t attempting the impossible.

When filming cheetahs, you can spend days sitting around waiting for them to move, and you’re thinking ‘Just do something interesting… Something I can film… Anything other than just gazing into the far distance!’. Then after a couple of days they will get up and go for a mobile lunch and you can hardly keep up, even in a Land Rover. Raccoons on the other hand are the exact opposite, when they are awake, they never stop moving – sure they rest up, but if a raccoon isn’t hidden away having a kip, it will usually be ambling along doing something interesting, and providing you aren’t hassling the creature, you can usually keep pace on foot.

With cheetahs - there's a lot of sitting around waiting.
Cheetahs are just about my favourite animal – they are beautiful, but there’s a lot of sitting around waiting, and to be honest… they can sometimes be rather dull.

A raccoon is an inquisitive creature – brighter than a rat, a cat, or a dog, they have a never say die attitude that provides an easy fit for those who think they’re a little bit like us… and in some ways, perhaps they are. It doesn’t make sense zoologically, but it’s fun to think of the raccoon species as evolving along a different route to create a creature that ostensibly does things the way we do, but without the advantage of starting from a primate.

Their little paws are superficially hand-like and with great sensitivity   can manipulate objects – in particular food, and their alert little brains will get them into just about everything, which helps them survive in all manner of circumstances. It all sounds familiar – especially the little brains!… We can anthropomorphise them to our hearts content and that’s certainly the reason they make such good cartoon characters… we relate to them, and their little bandit masks in particular trigger our imaginations. They appear to us as devilish little bandits behaving without restraint, which is exactly the mindset of any raccoon worth its salt – as anybody who has ever tried to keep one will tell you.

Raccoons in a natural situations do not shy away from water – this one is Canadian.

If you’re thinking that keeping a raccoon should be on your bucket list… forget it! It takes a very forgiving nature to become a raccoon’s best buddy. There are however people – like Dorcas MacClintock, who have managed to do so successfully, and on numerous occasions. In the mid-1980s Dorcas became my mentor in all things raccoon related; somehow she managed to bridge the gap between art and science; as both an award winning sculptor, and a respected mammalogist she had moved beyond the simplistic recording and analysis of racoons as living organisms to see the bigger picture. Dorcas also has a sense of humour which is not only helpful, but an absolute necessity when dealing with raccoons. David Niven once said of his friend Errol Flynn, that you always knew where you were with Flynn because he would always let you down – and that’s more or less the way it is with raccoons – you can’t  just turn your back and expect them to sit quietly – they’re going to get into mischief.

I had to empty the bookcase for my impression of Rocky Racoon. Dorcas MacClintock's book (left) 'A Natural History of Raccoons' is well worth searching out.

Dorcas taught me how best to understand what a raccoon will do next, which is essential when trying to film them. I learnt how to second guess their behaviour and anything Dorcas had forgotten to tell me, she had already written down in a book which she gave me. I learnt for example that you don’t try to stop raccoons from doing just about anything they want, instead you divert their attention with something more interesting and usually, that something is food.

A wild raccoon in a not so wild urban setting somewhere in the U.S.A.. The only part that is set up is extra lighting plus a little extra food, although finding dumped food is not exactly unusual in today’s urban landscape.

The truth is, I usually leave the captive raccoon diverting to somebody else because it’s a full time job and I just do my best to record the action. Working with a wild raccoon is pretty much the same – you grab what you can, because if a raccoon is doing anything, it’s most definitely worth running the camera.

With a racoon in the wild there is no doubting that the setting is natural, but with a captive animal, which parts of the process touch base with reality? Well, whatever a raccoon does is his or her own reality… because they will never do anything that they don’t want to, or anything that doesn’t come naturally. So, if the intention is to demonstrate some aspect of behaviour, I don’t think filming a captive raccoon is a major deceit, but if you are supposedly telling the life story of a wild animal and filming most of it on a set, essentially what you have is a soap opera, which is fine, but of no particular interest to me.

This is a raccoon on an open outdoor set, his name was Wille and he's been given water and appropriate food - so that I can film him dabbling - searching with his front paws and then washing his food.
This raccoon was cared for by Dorcas and his name was Willie. He was filmed on an open outdoor set with an artificial pool and given appropriate food so that he could dabble – that’s essentially searching for food in water using the front paws. There is some question as to whether this continues through to actually washing a potential meal – but that’s certainly the way it looks to us. Interestingly, Willie isn’t looking down too much, instead  he relies on his sensitive paws to feel what he is doing and appears entirely absorbed in his food gathering activity – but with his head up, he remains aware of his surroundings – even if, as is the case for all raccoons – he is rather short sighted.

The thing about filming natural activity is that unless you plan to make a twelve hour nature film, there has to be some editing, and I’m more worried about that than many other aspects of the process. One very good reason for editing your own material is that there is a better chance of telling the truth, simply because you were there. The alternative and often preferential route is to put a story together from bits and pieces filmed over a period of time, and some professional film makers might say that it will be a dull story if it isn’t done in this way. Which might be the case, but I think it far more interesting and informative to watch things the way they really happened. There is however compromise to any edit –  it might be necessary for example to drop  a close up in to move the action along, and so keeping the flow authentic is a constant challenge.

The viewer is always in the hands of the movie-maker, who has the option to tell it as it is, or alternatively, make a story up, and  to a point there is always a degree of manipulation. Secondly, nature isn’t    simply about getting bloody in tooth and and claw – animals attacking has become fashionable on both television and the internet, but watching animals going about their daily lives demonstrates that there is a lot more going on. Just as with us, everyday activities may not be quite as exciting as a battle, but raccoons tend to do things with more gusto than most and their behaviour is often comic, a combination that will always provide cinematographic value.

This YouTube of a raccoon dabbling is captivating, but clearly not of a captive animal – without edits the action retains a feeling of authenticity.  You might not want to watch the same behaviour for an hour, but a short clip like this is absorbing, and you learn something about the habits of a wild animal:  raccoon dabbling. https://www.youtube.com/watch?v=W0lI3ub3DI8

This is a wide view of Willie that shows him on the set I had built - you can see a flag to the left of frame (this used to take light out of an area - which might sound odd, but is a good way to create shadow where it is required. Filmed in daylight, it can also be used as a night scene. I dropped two f stops to create the mood (seen in the closer shot above). I could also have blued it for night, but have left that for the producer to make that decision as it may also be done in post production.
Here is a wide view of Willie, showing him on a set built for a dabbling sequence – you can see a metal flag to the left of frame (used to create a shadow in one particular area). Filmed in daylight, the image might also be used as a night scene by dropping the aperture a couple of f stops to create a darker mood (this shown below). I could also have blued up the image for night, but have left that for the producer to decide, as a final decision can be made later… and it also gives the producer a chance to make a contribution! O.K., just kidding!
Here the exposure is taken down to give the impression of night - it might be taken down further and blued - this is why it is important to light the areas of action precisely - as you need to see what is going on. I could have also done the sequence at night and lit that. The technical possibilities are endless and all without changing the raccoons natural behaviour.
When the exposure is taken down it can give the impression that this is night time and might be taken down even further and blued up for a cooler night time feel, this darkening of the image is the reason that it is important that the light is directed precisely towards where the action is happening, because above all else, the viewer must be able to see what is going on. Another option would have been to film the sequence at night and light appropriately, or use an infra-red camera. The technical possibilities are endless, but most importantly, they don’t change the raccoon’s natural behaviour. Working today with video many people are inclined to record exactly what they see through the view finder, often in low light conditions, which gives a very narrow depth of field (that’s overall focus front to back). It is quite tricky juggling light levels to create a mood on film, especially when the final image isn’t visible to you through the view finder which is the way it usually is if you are lighting creatively. Our eyes can read light levels more broadly than film stock and that’s useful, and without it, going to the movies wouldn’t be half so interesting.

Whether in captivity or in the wild raccoons appear delighted to have something to do – it is simply in their nature.   Out in the wild, much of what they attempt seems destructive to us, but really they are just making a living much the same as we do when going about our business, except that we trash quite a bit more of the environment than they do in the process. I understand why many people view them as a nuisance, nevertheless it is ironic that as we start to move into their world they have a habit of pushing back, and at some level, you have to admire that.

This is a wild raccoon. I watched his progress from behind, worked out that he was going for a swim -ran along the bank and found a bridge and returned to catch him arriving on the bank from the front. I could see it in his eyes - 'Oh, it's you again!'
This raccoon was photographed in the wild. I watched her progress towards the water ahead, and worked out the position she was most likely to enter the water – then ran along the bank of the stream, found a bridge and made my way close to the spot where I thought she would arrive on the opposite bank. I could see it in her eyes – ‘Oh no, it’s you again!’ But I was long gone before her arrival.

In all honesty, if you take a picture of a raccoon in its native country you probably won’t contribute very much to saving the planet, but if you live outside of North America and get a shot of one in the wild, it might prove very important to conservation. Certainly if this species takes off in Britain – a place where raccoons really don’t belong – they would undoubtedly compete with native species that are already under pressure and their presence create environmental havoc. If a raccoon really did think and behave exactly the way that we do, he’d probably be saying ‘ Nice one… Bring it On!’ But in truth, Rocky is just doing what all raccoons naturally do… and he doesn’t have an opinion one way or the other.

HAWAII: JUST ANOTHER DAY IN PARADISE. PART 1 – IT’S THE LITTLE THINGS THAT COUNT.

On a recent visit to Hawaii, I hardly saw any native wildlife, a stark reminder that things haven’t improved since I first came to film for the B.B.C. back in the early 1980s.

Aloha!
Aloha!

Thirty five years ago I made my first visit to Hawaii at a time when travelling to distant tropical islands from the U.K. was considered exotic. In those days, you’d emerge from a plane into the shimmering light and once down the gangway steps walk to the terminal building with the heat of the sun bouncing beneath your feet like a playful pet; and just as you were beginning to appreciate that life was all the better for being here, smiling girls in traditional dress would come out to greet you and place flower leis around your neck.

But things have changed… the sun still shines, but on more recent visits I couldn’t fail to notice that the girls were no longer present – the Honolulu Airport terminal is bigger now, reflecting that there are many more travellers coming to Hawaii and if every visitor was still receiving a traditional floral  greeting, the islands would pretty soon be clean out of flowers.

People still smile though, and the pace of life is slower than many of us are used to; pretty soon you feel relaxed because it’s difficult to find these islands anything other than enchanting, but my first couple of visits were not the magical encounters with paradise that I had imagined – mostly I was filming ten hours a day in a laboratory at the University of Hawaii.  I’d been sent by the B.B.C. to film a variety of tiny creatures and two oddities in particular – both spectacularly unusual carnivorous moth caterpillars.

Anything that has a sensory rear end that alerts to an approaching fly and then flips its front end over backwards to grab the unwitting insect in its jaws in a mere fraction of a second is a real attention grabber, but the little critters are just so small and well camouflaged, that if you didn’t know they were there, they’d might just as easily be  another twig on the tree.

Where else but in Hawaii could you find an insect so clearly associated with feeding on leaves that has switched to eating insects? And not just any insects, in this case Hawaiian fruit flies that have evolved to become spectacularly large, but nevertheless will go down twitching as they are eaten alive.

It doesn't seem likely, but there is is... a moth caterpillar Eupithecia streurophragma feeding on an Hawaiian fruit fly.
It doesn’t seem likely, but there it is… the moth caterpillar Eupithecia streurophragma feeding on an Hawaiian fruit fly.

 Hawaii is an extended chain of islands which has formed over a mid-Pacific hot spot of volcanic activity,  roughly equidistant between Eurasia and the Americas; and to get to either requires an approximate two and a half thousand mile journey either east or west across the Pacific Ocean. It was this creation of land by fire combined with a perfect storm of circumstances that allowed for the evolution of so many unique and unusual lifeforms.

These Islands might be regarded as a natural laboratory for the study of evolution, and if Charles Darwin had landed here rather than on the Galapagos Islands he would have come to similar conclusions about how species evolve when  separated from their relatives on distant mainlands, and even from those isolated on different islands… but Darwin would have needed to be paying attention (clearly one of his strengths), because many of the animals concerned are small invertebrates, such as spiders, insects, crustaceans and molluscs.

Certainly limited numbers of creatures would have made it to the islands to start the evolutionary ball rolling and no large animals were amongst them – other than those that could  swim here – turtles for example, and they never get further than the beach. Consequently no native reptiles, amphibians or mammals ever made it to the islands until their arrival alongside man, either as stowaways or transported intentionally, with frequently disastrous consequences to the native flora and fauna.

Small arthropods such as insects, spiders and crustaceans will most likely have arrived on floating vegetation, the lucky winners hitting this narrow window of opportunity, whilst the majority missed the jackpot and drifted on across the world’s largest ocean to become lost at sea.

The initial arrivals had the advantage of making landfall on uninhabited islands which provided a variety of empty niches ready to move into – and those that managed to adapt to their new circumstances would have radiated out into different habitats to eventually form species that were unique.

abd
The Hawaiian Islands were at one time or other no more than volcanic larva flows and it is no surprise that the wolf spider Lycosa has evolved adaptive colouration to live in what might elsewhere be considered unusual surroundings, in particular larva cinders in desert areas.

The habitats available for life in Hawaii were varied, and included not only forest, grass and wetlands, but also larvae flows, deserts, beaches and caves – all of these would become populated by invertebrates; there is even an small creature (the wekiu bug) that lives at altitude, sucking the juices of insects that have been caught up and preserved in snow and ice to be released many years later as frozen dinners along the thaw line of Mauna Kea, a dormant volcano and the highest point in Hawaii.

A cricket that appears so well camouflaged on larva flow I could just as easily have photographed only the larva flow and then tell you it was there.

One species peculiar to the Islands is the happy-face spider, which derives its name from an apparently smiling face on the upper side of its abdomen; this tiny spider mostly lives and hunts on the underside of leaves and despite its size is visuality impressive.

The morph shown below is the one most commonly seen, but there are a variety of others that have extraordinary clown faces on their rear ends and you might want to Google  ‘ happy face spider images’ to see more impressive examples. The spiders have made it onto four Hawaiian islands but are not yet on Lanai, nor have they managed to get as far west as Kauai.

I had a couple of happy face spiders to film, but since I photographed them many more extraordinary faces have been captured by by photographers. Just Google Happy Face Spider to see some extraordinary morphs.
In 1980 I had only a couple of happy-face spiders to film – the disappointment was their small size, which made filming their behaviour a challenge.

It appears that almost everything that arrived in Hawaii evolved into  something special… but then man arrived and the party was over, which is a sad but familiar story!

The islands by dint of their remoteness have undergone extraordinary speciation in the absence of too many predators or competitors, but once these were brought in from elsewhere, many native species were immediately threatened. Indigenous plants and animals have become well adapted to their circumstances but they have not evolved appropriate defences against the onslaught of the new invaders. And so it was, that species in existence for millions of years, were snuffed out by the newcomers like candles in the wind.

Many of the new arrivals were so closely associated with man and his agriculture that with the additional advantage of a perfect climate they thrived in their own little paradises within paradise – and from there ventured out to invade other places on the Islands.

The first aliens will have come in with the Polynesians between 300 and 500 A.D. Then the Europeans showed up; it is possible that the Spanish arrived a couple of hundred years before Captain Cook made landfall in 1778, but it is Cook that we remember because he claimed the Islands as British territory, which now counts for little more than the hoisting of an interesting union flag colonial combo.

Flags are not traditionally Polynesian; these two flutter beneath an Hawaiian sky as a reminder of the transient nature of colonialism.
Flags are not traditionally Polynesian; these two flutter beneath an Hawaiian sky – a reminder of the transient nature of colonialism.

The islands were named after Cook’s sponsor, the 4th Earl of Sandwich – the very same Earl who found himself disinclined to leave a gambling table and suggested to staff that they bring him food conveniently held between two pieces of bread… the rest of course is history… as is the case for the naming of the Sandwich Islands which later reverted to their more appropriate Polynesian name – or at least a close approximation to it.

Colonisation would be instrumental in the devastation of many indigenous species causing the rapid degradation and destruction of habitats; this combined with alien introductions became the driving force for many island extinctions.

It was decided that I would film snails to illustrate the troubles caused by introduced species and I was pleased to be filming at least some of them out of doors. There are many valid reasons for filming animals in their natural environments, but invertebrates are often the exception, usually their behaviour is not much affected as long as their living conditions are adequately simulated.

Prior to the early 1980s film stocks were limiting and a lot of light was required to capture the activity of any small creature in movies. This was just before cold light using fibre optics became widely available, and I had to devise my own water cooling system bolted to the front of lights which required a constant flow of cold water to substantially reduce temperatures. In the years to come I would replace my cumbersome system with cool fibre optic lights; this was really helpful because invertebrates can’t cope with excessive heat, but rarely are they bothered by extra light, and for the best results good lighting was essential.

There is also a moral question as to whether this is truly wildlife photography, but imagine carting all of this gear into the big outdoors to capture perhaps fifty different creatures in various locations across the islands – setting up on steep slopes for example – because hardly any fertile natural environments have escaped cultivation on the flat – and then there are the cave habitats which are a nightmare to get equipment into. Time and budget constraints required everything to be done in a few weeks (and today these constraints are even tighter). There was then little option other than to bring many of the smaller creatures to one place in order to get the job done.

Taking a still flash photo on location is one thing, but filming the very tiny with plenty of light without any vibration has always been a wind up, and there is the additional problem that when visiting delicate environments trampling has to be avoided, along with the possibility of losing invasive species to the wild. Back then, despite all the disadvantages that the real world presented to macro-photography, I still had to establish some environments on wider lenses and in the process was determined to film at least some of the native snails in the big outdoors.

I was once embarrassed to lose a large tortoise whilst filming in Africa – it made off (across its natural habitat) when I left for a short while to fetch a lens – I had assumed that it wouldn’t get too far, but of course, tortoises run at breakneck speeds when you stop watching them.

I learnt a valuable lesson… but even at my most inattentive, I thought it unlikely that I could misplace a snail, not even a well camouflaged individual, but the truth is, it’s easy to lose sight of almost any snail by simply looking away… and given half a chance they’ll dash off and hide under a leaf when you do. Living in a small world – your perspective on life changes and when you’re not worrying about snails rushing off to hide, you’re worrying about the fact that some move so slowly they won’t register as moving at all in real time. But of course, things could have been worse… ants are always in such a rush, so it was great to discover that there are thought to be no native ants living on the Islands at all.

There are more than 40 species of  endemic tree snails living on the Hawaiian Islands and all are endangered - this one seems hardly to have managed to have held on to a protective shell at all.
There was once around a hundred species of tree snails in Hawaii and now only about a quarter remain – most of which are endangered – and this one seems hardly to have held on to a protective shell at all.

Until recently Hawaii held the most diverse representation of land snails anywhere in the world, but since the arrival of humans it is likely that around 75% have become extinct. Habitat loss will have played a part, but many have been eaten out by introduced predators, in particular predatory snails.

After the African land snail Achatina fulica was introduced – it’s a monster and ends up elsewhere either as a food source or as a pet – it soon became clear that the newcomer was munching its way through the Hawaiian natives, and so another predator was introduced from Florida – the rosy wolfsnail (Euglandina rosea)  to control it – and there wouldn’t be much of a story unless the new arrival had set about the native snails even more ferociously than the problem snail it had been brought in to eliminate, which of course it did, reducing native species even further, and pushing some to extinction… This was without doubt a ‘doh!’ of Homer Simpson proportions.

It is clear that when humans get environmental issues wrong, they make a really great job of it, and often eliminate species that have evolved to become spectacularly different from anything else on the Planet. The problem is, that when this happens to invertebrates… hardly anybody notices.

 It is the larger cuter animals that usually grab our attention, but when it comes to extinction we need to consider the smaller things in life, because if we include them, the losses that are presently occurring on a worldwide scale indicate that we may be entering a mass extinction event. Long term, this makes no difference to the Planet, but species diversity remains the best measure of the prevailing conditions for life on Earth and that is an important consideration for all of us.

Our own well being can be gauged by what is disappearing around us, and it is possible that any who travel might at one time or another hit the jackpot, and take a picture of some small creature that is unknown to science. Seeing the bigger picture means looking out for the small stuff, which is one of the best ways to save the Planet… or more precisely… the life upon it.

With thanks to former BBC Natural history producers Richard Brock and Roger Jones who gave me my first opportunity to film the natural history of Hawaii, Ken Kaneshiro for fruit flies and lab space, Frank Howarth for his cave critters and Steve Montgomery who collected many of the specimens for filming; he has been foremost in discovering many new species on the Hawaiian Islands and continues to do great work bringing the uniqueness of island biodiversity to the rest of us.
