A Tree of Life: How The Trees in my Paintings are so Much More than Props
A Rare, Living Elm
On the wooded slope of a valley that sweeps away from my home and gallery in Thixendale, grows one of England’s rarest species: a magnificent old elm tree. This big, beautiful, tree is one of just a handful of living elms left in the country. At one time these elms dominated the English landscape. But more than 60 million were killed in an epidemic of Dutch Elm Disease that all but obliterated the species.
Home to Wildlife all Year Round
In winter, with its leaves all gone, you can really appreciate the beauty of the tree skeleton of this particular elm. It has branches that twist and sweep gracefully to the ground and is topped by a thick thatch of twigs. On a winter’s evening pheasants roost on these branches, their dark silhouettes looking like huge Christmas decorations. And by day, this elm is a roost for tawny owls.
In the summer, when the owlets fledge, they form a crèche in the branches and the parents sit close by keeping an eye on them. Stoats also frequent the hollow around the roots and an array of small birds feed among the leaves. In recent years, I’ve noticed a clutch of barn owls, peppered through its branches. Tawny’s can be aggressive, so it was astonishing to see these two species of owl sharing the same canopy.
Other Life-Giving Trees
Although this tree is rare, all trees are known life-givers. Here on the Yorkshire Wolds, the ash trees are popular with green and great spotted woodpeckers, robins, and redstarts. Treecreepers also like to nest under the peeling bark.
Trees Provide Shelter & Food Even After Death
I have found that even when trees have died, they continue to support life. Elm is a very hard wood and many trees continue to stand long after being pronounced dead. Their trunks remain a feature of the landscape for years, like skeletons, their bark slowly peeling away and the bare wood beneath bleaching in the sun.
On the farm where I grew up, in nearby Givendale, I remember one dying elm with a large hollow burr on it. A pair of little owls returned there year after year to raise brood after brood. Another dying elm I knew of was home to a pair of barn owls and the roots of yet another became home to a stoat family.
Transforming an old elm into a bird box
Some years ago I came across an enormous fallen elm during a cold winter walk. I loved the furrowed, silver of the bleached bark. There was a section of it that had a worn entrance hole and this was full of character. Inspired by the gnarled shapes in the bark, I decided the hollow trunk would make a good prop for a bird to perch on in a painting.
To persuade a wild bird to pose on, I hit on the idea of turning it into a giant nest box. And so, with the help of a friend, I hoisted it into the back of his truck and took it back to my workshop.
I spent most of that Christmas sawing the edges of the jagged trunk to turn it into a usable bird box. It was a huge piece of timber, measuring 5ft high and 5ft across. I trimmed the top and bottom off so that I could put a roof and a floor on. But it was still too big to manoeuvre and so before attempting to hoist each half into place, I sliced it down the middle like an Easter egg,
I wanted to put the elm box into the fork of a sycamore tree that, ironically, grows close to the live elm tree near my house. So I built a platform and placed this in the sycamore for the box to rest on. It was too heavy to lift, so I used a pulley attached to my car to winch it up into place. As my wife drove the car slowly backwards, I stood on a ladder guiding it up. Then I put the two halves back together once it was up.
Soon Owls Move In
The following year a pair of tawny owls nested in this grand old elm nest box. And the box has been used every year since by different barn owls, kestrels, and tawny owls. I have painted these bird’s portraits posed at the entrance of the box again and again.
It wasn’t long before I added cameras to the box so that I could watch the birds as they reared their young inside. One summer, seven barn owl chicks were raised inside it and I was able to watch them from the moment they hatched to their first, hesitant flights. Watch the clip below to see them all dozing off inside the nest box in the warmth of a summer’s afternoon.
Elm’s visitors include smaller birds, stoats & squirrels
One autumn, my surveillance camera revealed a total of seven different species visiting the elm stump over the course of a week. I watched transfixed as my recording played back a tawny owl, a pair of kestrels, a barn owl, a blue tit, and a treecreeper – which climbed steadily up, and then down, the stump, combing the rutted surface of the bark for insects.
And these were just the bird species. The camera also caught a stoat investigating the box and a squirrel climbing awkwardly, one back leg stiffly following the other, through the hole.
Symbiosis Inside the Elm Trunk
The relationship between the wildlife species sustained by my decaying elm trunk is fascinating. The process is symbiotic. First, the owls or kestrels nest inside, raising their young. Here they cough up pellets made up of the undigested skeleton and fur of the voles that they eat.
The clothes’ moth, Endrosis Sarcitrella, or white-shouldered moth, then lays its eggs inside these pellets. When the larvae emerge they feed on the fibres of vole fur before crawling up the sides of the tree hollow, to pupate in the crevices.
Here the larvae become fodder for treecreepers, wrens, blue and great tits, helping to sustain these small bird species through the winter months. The decaying pellets also attract flies, which in turn draw spiders that attract small bird species.
The Cycle of Life
And so the cycle continues. It is heartening to think that my old elm trunk, years after I found it and took it home to use as a backdrop for my paintings, and possibly decades after it actually died, is still giving life to so many creatures. I am so impressed with it I have named it the ‘tree of life’.
Making More Nest Boxes From Old Tree Trunks
The success of this old elm box has led to further projects. An old friend of mine has a wood yard and often lets me have hollow branches or trunks if they have a natural entrance hole in them. I now have more than 10 boxes made from elderberry, elm, beech, ash, elm, and sycamore. I’ve noticed the birds of prey choose different boxes to nest in each year. In recent years I’ve also adapted smaller branches into nest boxes for stoats and weasels and one of my latest paintings features a stoat peering out from the entrance of a hollow ash log, see below.
Woodpecker & Wren Beat Holes in the Box
Each box has a camera either hidden inside or trained on to the outside relaying live images of the secret life of its occupant back to my studio. A box I made from an ash stump was a favourite with the kestrels living here this year. But a great spotted woodpecker hammered a dent into it and now a wren is making it worse and threatening to drill right through. But this is a nuisance I’m happy to live with since I get to watch these birds closely via my cameras.
It is nice to know that trees never stop sustaining the living. And that my special bird boxes go on to give old and fallen trees a new lease of life – both as bird boxes and as natural props in my paintings, films, and photographs.
