You know how it is, you’re having a perfectly normal conversation with somebody you think you know, and suddenly they say, ‘That’s just not like me, I’m a Capricorn’, and you’re thinking, ‘I hadn’t realised you were as daft as a brush’… <\/span><\/p>\n\n\n\n

The great thing about owls<\/a> is they aren’t like that — millions of years of evolution have honed them into ultra-efficient killing machines and none will make a judgement based on your star signs. Probably what they’re thinking when looking at you is, ‘I’m sure that thing’s too big to eat; but I’ll keep watching in case it’s dangerous?’ <\/span><\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

All that owls<\/a> need to do is catch and kill prey on a regular basis; find a mate, then a suitable place to nest and rear offspring successfully; and for all of these things natural selection has adapted them well… otherwise they’d be extinct. Survival doesn’t require cleverness in the way that we think of it; no owl will be entering a pub quiz any time soon, because that’s not what ‘wise owls’ do. <\/span><\/p>\n\n\n\n

Here’s ‘a wise owl’.<\/strong> Certainly this one’s fairly cute for a killing machine, but clever?…That’s a different story. <\/span><\/strong><\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

The impression we have is that owls are thoughtful, because unlike most birds they have flat faces and as predators need to judge distance using binocular vision; consequently, their eyes are located at the front of their heads, and these organs of vision are usually so big and adorable they are a super stimulus for our brains and this encourages us to like them. Add to this, beaks that look a bit like noses and suddenly we’re thinking, these creatures look a bit like us, so they must think like us… but that’s really stretching it. <\/span><\/p>\n\n\n\n

When I turned my wife into Christina Robin for her birthday, the joke wasn’t so much about her mild mannered attitude towards childhood friends, but rather, that none of them were very bright — Wol couldn’t even spell his own name and he was supposed to be the clever one; and despite not being a stuffed toy like the others, his general lack of knowledge suggested that it was a close run thing.<\/em><\/span><\/figcaption><\/figure>\n\n\n\n

Various animals seem to grab our attention — mostly mammals; but frogs, toads, parrots, owls and even snails have their fans. Owl enthusiasts will surround themselves with imagery relating to their favourite subject — pictures on the wall, place mats on the table and cuddly toys in the bedroom.<\/span> <\/span><\/p>\n\n\n\n

For the love of owls..<\/span>.<\/strong><\/p>\n\n\n\n

I don’t see myself as a rabid owl enthusiast and yet after a head count I’ve noticed quite a few dotted around the house. Rooted somewhere deep in our psyche these unusual looking bird are just waiting to come to mind, but over the years my relationship with them has been mostly practical: every now and again I’ve been required to film one, and suddenly they’re part of making a living.<\/span><\/p>\n\n\n\n

The first owl I filmed for television was for a documentary on the wildlife of churchyards — it was a barn owl<\/a>… or to be precise, it was three barn owls, and they taught me something… These are beautiful birds but have a habit of making their surroundings surprisingly dirty for all their hauntingly pristine whiteness. Clearly, the magic hold that owls have over our minds turns almost everything that they do into a positive. <\/span><\/p>\n\n\n\n

Owls push out waste material from both ends, which you really start to notice when you spend long hours working with them. Most creatures excrete from their rear ends, but owls also regularly throw up pellets — waste materials of digestion that attract flies and other small creatures to feed and lay eggs upon these macabre little parcels.<\/span><\/p>\n\n\n\n

\"\"

During the spring of the project I was suddenly looking after three young captive barn owls, converting my Victorian outhouse into a film set, and constructing a window from which they would hopefully emerge as if from a church tower.<\/span><\/p>\n\n\n\n

In reality churches haven’t had owls or even bats in their belfries for a very long time, because those responsible for maintaining the interiors of churches prefer to avoid accumulating bat poo, bird droppings and owl pellets.<\/span><\/p>\n\n\n\n

\"\"

For years now, the chances of finding owls spending their days hiding away in church towers has been reduced to almost zero, as most windows have been meshed to prevent birds from entering. <\/span><\/p>\n\n\n\n

However, if owls had still been living a church going lifestyle, the only other option would have been to build a scaffold next to a church tower from which I need to film a single shot, and that wasn’t very cost effective. Back in the 1980s, it was easier for me to build a church window set and film captive owls coming and going, even if in reality they’d be unlikely to do so. <\/span><\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

Wildlife film-makers rarely admit to deception, but we all have to own up to the realities of what is possible in a world that is rapidly disappearing. I don’t think it matters one hoot whether an owl exits a real window, or a fake one, because nothing about the bird’s behaviour changes. Nobody questions an edit in a natural history film, because if an audience wanted to experience natural events in real-time they’d be waiting for days. However, as soon as you tighten up the progress of events the result is a story; and the real problem with telling a story is the disappointment of the viewer should they discover the deception. <\/span><\/p>\n\n\n\n

\"\"

So, there I was… faking it; building a facade on the front of my outhouse and using the outdoor toilet next to it as a hide to film from, essentially by knocking a small hole in the wall. On the outside of the set window was an outdoor enclosure into which the owls could emerge, but they never did. Even sitting in the window would have been helpful; and if flying was beyond them, just hopping out of frame would have been enough, but they wouldn’t do any of these things. It was a complete waste of time, and I ended up feeding the birds inside the little room they’d adopted as their home, a home that I never managed to persuade them to leave. <\/span><\/p>\n\n\n\n

\"\"
All that was needed was the grouting between the bricks, and the scene, when lit for night, would be quite believable; but as not a single owl ever exited through this window, my efforts were a waste of time.<\/em><\/span><\/figcaption><\/figure><\/div>\n\n\n\n

The outhouse was next to the kitchen, and the flies coming to visit the mess the bird’s created was disagreeable. The owls weren’t equipped to fly any distance; and after a couple of months I returned them to the person who had reared them in preparation for release into the wild. I am aware that most owl enthusiasts would be singing the praises of experiencing such wonderful birds first hand, but I couldn’t wait to see the back of them. They whole thing had been a time consuming failure. I’d been unintentionally mislead about what these owls would do, and was a long way past the point where I was going to train them to fly through my phoney window. They were the wrong birds for the job and never again did I make such an expensive mistake. <\/span><\/p>\n\n\n\n

‘One Man’s Owl<\/a>‘ Bubo, when a young bird.<\/em><\/span><\/figcaption><\/figure><\/div>\n\n\n\n

Soon after my year of filming in graveyards, I moved onto another film project for the BBC in the backwoods of Maine where I would meet a <\/span>great horned owl<\/span> <\/a>destined to become one of the most famous owls in natural history writing. I returned to Maine on several occasions over the course of the next year and a half, spending much of my time high on a wooded hill at the camp of scientist and writer Professor Bernd Heinrich<\/a>. The thing about Bernd is that he is not only an exceptional naturalists but one of the most impressive zoologists of his generation. He’d rescued a fledgling great horned owl from the snow and the bird was always somewhere close to his cabin, either sitting on a log, or in a tree close by. He had been named Bubo: if you can name a hobbit Bilbo, then why not an owl Bubo, after all it is latin for his Genus — the New World horned owls and Old World eagle owls make up the genus Bubo<\/a>. <\/span><\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

Eventually, after many hours of<\/span> observation, Bernd wrote ‘One Man’s Owl<\/a>‘ which like most of his books became a classic of natural history writing. The bird was semi-wild, and would come to Bernd without much trouble; better than that, he would fly to food in a manner that was entirely predictable. One day Bernd dangled something dead and unpleasant just behind my head and young Bubo came swooping in to take it, providing a shot I could never have achieved in the wild. We repeated this several times, the owl on each occasion dropping from it’s perch just a little way off and then gliding towards the lens, dipping low enough to appear as if he might be about to crash into me, but rising at the last moment to a position just above my head — each time I felt claws brushing through my hair, but they didn’t close until locked onto the free lunch that I couldn’t exactly feel behind my head, but could faintly smell. When a bird of prey’s talons touch prey, they usually snap closed as a reflex action and my hair got pulled, but it was nothing personal. If an owl really flies at you with intent… then you certainly know about it.<\/span><\/p>\n\n\n\n

A great horned owl has a pounds per square inch (psi) grip of around 300 — 500<\/a>, whereas most humans manage a grip of just a few pounds per square inch.<\/span><\/em><\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

A few years later I found myself in the high mountain woodlands of New Mexico filming the small nocturnal flammulated owl<\/a>. It was a surprise when the scientist working with the birds told me he could chainsaw out the back of the tree they were nesting in and they would remain entirely undisturbed. If you needed to observe or weight young birds this was perhaps an effective way of doing it, but I was sceptical. Chainsawing a tree before the owls started nesting seemed a better option, but how many trees would you need to cut into to guarantee a nest being present later in the year? Predicting such events is very hit and miss.<\/span><\/p>\n\n\n\n

This picture was taken to reference an owl in place: it is obvious that the sudden daylight was inconvenient, and although woken the bird wasn’t stressed. It is important to read an animal’s demeanour, because that will indicate what you can or cannot do. The film sequence involved more directional lighting, with a suitable exposure to create the impression that the bird was tucked away in the tree; and tightening up the shot to reveal only the interior made the sequence believable. <\/em><\/span><\/figcaption><\/figure><\/div>\n\n\n\n
\"\"
A flammulated owl watching from a nest hole in a broken off pine tree. The bird can be seen looking out about 10 inches above the top of the ladder. Mostly, I would secure the ladder to the rear of the tree to film the nest internally.<\/em><\/span><\/figcaption><\/figure><\/div>\n\n\n\n

The section removed from the back of the nest could be taken out when filming, then set back and wired into place very quickly. There are probably a dozen good reasons why this wouldn’t be done today, one of which is that flammulated owls are now endangered in some areas of their range. For the most part this has been down to habitat loss. After being set up by the bird biologist, I filmed the owls both during the day and at night using artificial light — but standing at the top of a ladder tied almost perpendicular to what remained of an old conifer miles from anywhere, in otherwise total darkness, was rather spooky.<\/span><\/p>\n\n\n\n

The filming occurred more than 35 years ago when a great many species were far less threatened than they are today; but even back then if I hadn’t been confident about what I was doing, I wouldn’t have been filming; and in this case, certainly not without the supervision of a scientific advisor who had been working closely with the birds. I haven’t named him because many will consider this kind of intrusiveness unacceptable; but as none of his birds ever seemed disturbed and the information gleaned went into conserving the species, I didn’t have a problem with it. Nevertheless, I am not sure we need to see every wild bird on the nest just for a television programme, although there is no doubt that this kind of media exposure is the best way to get a general audience informed and proactive in conservation… But don’t try this at home… you might lose an eye! The alternative is to film captive birds on sets and there are many people who are equally disturbed by this alternative dishonesty.<\/span><\/p>\n\n\n\n

\"\"

Using artificial light attracted more moths that I have ever seen at any one time outside of the tropics. The owls were easy going, but there was always the potential danger that an adult bird arriving back at the nest might get spooked and launch into my face. Owls have inflicted serious damage to people who have worked this closely with them in the wild, causing facial damage and even the loss of an eye. <\/span><\/p>\n\n\n\n

I was filming less than a foot from the bird, and couldn’t believe how tolerant the flammulated owls were, although I only worked with birds for very short periods, never more than 20 minutes a night before leaving them to get on with their lives.<\/span> The success of the project was mostly in the planning; followed by working quickly without any sudden movements that might disturb them. I used a variety of techniques to minimise disturbance: a light source that could be turned up rather than one that could only be turned on, and dark gloves to prevent sudden glare from my hands. Simple things but very effective.<\/span><\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

Unless a hide has been set up and birds are entirely unaware of your presence, the 20 minute rule is a good one. I’ve worked in this way with several bat species including vampire bats at their roost as well as variety of nesting birds, but you can’t do this with every species. <\/span><\/p>\n\n\n\n

Some birds are not troubled by this kind of exposure, but many will be, unless you have almost unlimited time to get them used to a new experience; most importantly you can’t just try it out to see, and that is why such filming endeavours work best if they are associated with a research project that has already clearly defined the ground rules.<\/span><\/p>\n\n\n\n

This tawny owl<\/a> sitting on a camera in my studio was a star. If there was ever an owl that made me question my view that owls aren’t especially bright, then this was the one. <\/span><\/figcaption><\/figure><\/div>\n\n\n\n

I have in the past been fairly mean when using film stock and there are many occasions when I didn’t wind on far enough before taking pictures, resulting in a light leak that affected the first frame of the roll. For some reason when I photographed owls this happened rather a lot, but I often quite liked the results. I could claim that these were artful pictures, but I won’t go that far — although the random nature of what turned out was often quite interesting.<\/span><\/p>\n\n\n\n

‘Tawny in Red’ was a resident at the Hawk Conservancy Trust at Weyhill, Hampshire <\/a>and it was an extraordinary bird. This owl would fly to wherever was required and land to order; and rather usefully could fly slowly alongside a moving vehicle so that it might be easily tracked by a camera. Straight away I must admit that owls are capable of remarkable things, but in fairness this birds super abilities were to some degree down to handler and Trust Founder Ashley Smith, but there was no doubt in my mind that this was a very special bird.<\/span><\/p>\n\n\n\n

This wild burrowing owl<\/a> was photographed on open grassland, and had the habit of standing tall, stretching itself up to gain a little extra height when it was trying to make out anything that was moving, often at some distance. This was accompanied by complicated head movements, giving the bird a comic demeanour. The behaviour however was strictly functional, allowing the bird to judge distance. The owl would react this way when anything new came into view: this might be an old bag blowing in the wind, a coyote, or just a human who hadn’t yet noticed the owl was there — in the reverse situation the observations were seldom as acute: people just don’t notice as much as an owl does; certainly any owl that takes the trouble to monitor its surroundings is more likely to survive than one that doesn’t. <\/span><\/p>\n\n\n\n

\"\"
An old pipe is a very suitable home for a burrowing owl.<\/em><\/span><\/figcaption><\/figure><\/div>\n\n\n\n

Everybody has favourites, but more often than not, mine are functional. Burrowing owls are high on my list because they are active during the day which gives a film-maker at least a chance. In the mid 1980s I worked with these delightful birds on a site in New Mexico and became quite enamoured by their behaviour. <\/span><\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

They would sit outside of their burrows during the day, or on top of a dead tree stump or power line pole, but unlike most owls, were more inclined to present more interesting daytime behaviour. Many species remain at rest during daylight hours, giving you little more to film than a rotating head and the occasional blink; but burrowing owls are different — they are generally more dynamic, even if sometimes this involves little more than moving in and out of their burrows. Movement is essential to a television audience’s experience; and usefully the most dramatic activity these owls would perform was to dive-bomb walkers and joggers; joggers being the preferential targets, perhaps because they were moving faster and considered more of a threat.<\/span><\/p>\n\n\n\n

\"\"

Perhaps because I’ve been involved with moving pictures for most of my working life, I also like to see some movement in my stills, although achieving the appropriate amount of blur can be very hit and miss. I hardly ever use flash photography, although doing so provides a sharper image which is preferential to some, but it isn’t a priority for me; and I wouldn’t in any case use flash with owls because they are such light sensitive creatures.<\/em><\/span><\/figcaption><\/figure><\/div>\n\n\n\n

Several years after filming the flammulated owls, I took a road trip with my wife Jen across Route 66<\/a> and made a slight detour to re-visit my old favourites. Unlike so many animals I have returned to see, the owls had not been swamped by development or disturbance. They were living their lives pretty much the way they had been on my previous visit when I’d had the luxury of being paid to be in their presence and could give them far more time. <\/span><\/p>\n\n\n\n
