Farmoor's Ghosts 22nd January 2020


Barn Owls and Kingfishers are both resident at Farmoor and are arguably the two most desirable birds to try and see on any visit there. Both species can be seen with patience and a little local knowledge. The Kingfishers that visit the pool at Shrike Meadow have now become so well known that the  previously unoccupied hide is now often full, as birders but mainly photographers come to get that 'particular' shot of it, sat on its post in front of the hide.

Today I went to the hide but it was full of photographers waiting for a Kingfisher to arrive and I rapidly retreated, deciding to go and look for Barn Owls instead.

I do not get on well with hides as I do not care to be enclosed for too long with other people unless I know them well. I can also be a bit anti social at times, preferring my own company. It's not that I do not like people and if you sit in a hide you need to recognise that others are just as entitled as you to be there but it's the chatter that you often have to put up with, the constant blather about camera settings, where you should go for the best results for this bird or that, the attempts to out do each other with birding tales or photographic experiences. It drives me to distraction. It's not only in hides either, the same frequently happens outside as well, wherever birders congregate in numbers.

For me birding is intensely personal and emotional, incorporating a whole gamut of both spiritual and esoteric experiences. On my own an encounter with a bird is a world of difference to when I am  in the company of others, even those you like and trust. You have time to feel the essence of the bird you are watching, its surroundings and how it affects you. There are no inter personal distractions and you are free to do as you please. It all combines into a similar experience as, say, going to the theatre and enjoying a really good and uplifting performance. Even when the bird has flown you are left with an intangible sense of well being, a feeling of having achieved and enjoyed something all by yourself and out of the ordinary. Whilst walking alone, birding, thoughts often pass through my mind that have nothing to do with birds but somehow they too become a part of the whole experience and in  some cases act as a therapy. There is a word for it now called Mindfulness. 

I should also like to make it clear that I have met many nice people in hides and have had rewarding conversations and you know who you are, so I trust you will forgive this mild diversion from the normal.

Enough said. 

The Barn Owls at Farmoor are well known  to the general public and birders alike as they often hunt during the afternoon in broad daylight and are therefore conspicuous. They are also used to encountering birders, dog walkers and ramblers and as a result do not seem overly concerned about a human presence, although they remain reasonably wary. Here also, they are safe from collision with vehicles, a frequent fate for Barn Owls that hunt the verges of our busy roads in Oxfordshire and elsewhere in Britain. 

Everyone loves a Barn Owl. There is something about an owl that imparts an overt contact with the wild. They are secretive and mysterious, legend and fable are attached to them from down the centuries, so when one comes to delight us, such as at Farmoor, there is that thrill of encountering something special, no matter who you are. To see one suddenly appear, silently floating on soft wings over the rough grassland and the scrub of long dead willowherb and meadow sweet adjoining the reservoir, brings a sense of the magical, as if with the owl's presence the whole area has been transformed out of the ordinary and will remain so until it departs.

The Reverend C.A Johns wrote in the nineteenth century of the Barn Owl's flight as follows:


......how stealthily they fly along the lanes, dipping behind trees, searching round haystacks, skimming over the stubble, and all with an absence of sound that scarcely belongs to moving life. Yet, though by no means slow of flight, the Barn Owl can scarcely be said to cleave the air, rather, it fans its way onwards with its down fringed wings, and the air, thus softly treated yields to the gentle force and retires without murmur to allow it passage......


Dai, who lives locally and goes birding at Farmoor virtually every day had told me that recently two Barn Owls had been seen hunting over a particular area of rough grass and umbellifer scrub owned by Thames Water, that lies between the reservoir and the River Thames. I made plans to go there. 



They can appear at anytime but usually it is in the afternoon and they are well worth going to see. Sadly such a sight is all too rare now as Barn Owls have become scarce due to habitat degradation and the loss of barns and outhouses to breed in. Artificial nest boxes have gone some way to redress the loss of breeding sites but the overall population remains low, so we are indeed privileged to have them at Farmoor.

The location in question at Farmoor is at first sight unremarkable, you could describe it as waste ground but in weekdays it is a peaceful and quiet haven despite being close to busy roads and two large villages. The river that runs by it is, at this time of year, untroubled by boat traffic and although the Thames Path winds its sinuous way along the river bank there are few people using it in winter apart from the regular dog walkers. Looking to the west my eyes pass over a rural scene of  pastoral meadows, the timeless river and then beyond to the stark outlines of winter trees in the distance. It is hard to realise you are only a few miles from the centre of Oxford.


Taking Dai's advice I made a visit to Farmoor on Monday, getting there in the early afternoon and stood alone in bright sunlight and with a certain stillness embracing the land that only a cold winter's day can bring. Looking west over the fields I  could see the effects of the rain that has been falling for so many days. Fields normally green and with sheep grazing were underwater and gulls, geese, ducks and swans were taking advantage of this new, albeit temporary habitat. The river was swollen to a brooding monster, running fast with a relentless and powerful force, flattening the reeds and vegetation at its edges, the water level high enough to have breached the banks and isolated trees in their own private lake.

At just after two pm a Barn Owl came from the west, ghostly pale in the sun, flying distantly and low along the perimeter of the flooded fields, its wraith like form moving steadily to pass across an indeterminate dark hedgeline, the distinctive stiff wing beats of its flight bringing it closer and closer. It rose to some height and floated across the river, then descended in a series of quick shallow flaps and occasional glides, tilting and swerving, responding in an instant to whatever attracted its attention on the ground. It proceeded to hunt across the expanse of dead and flattened stalks in front of me, quartering back and fore alongside the threadbare hawthorns that run on each side of a path that leads down to the river. It passed before me, moving away and then came back, its heart shaped face, a halloween mask held steady between its long wings.








The head of a Barn Owl is large, out of proportion to its slender body, giving the bird a front heavy, blunt faced appearance which is very apparent when they are seen in flight. The head is the business end of the owl, where the incredibly sensitive ears are located, below the eyes, in a round disc like face that serves as a sound receptor. Its hunting strategy is to locate prey by sound as it flies silently on specially adapted wing feathers, then dive and at the last moment before impact locate its victim by sight, whilst bringing forward the talons to seize and kill the prey. Many such attacks fail and the owl will persist until it meets with success, occasionally perching in the meanwhile, as if to take a break and make an assessment of its situation, before resuming the hunt.

The owl circled round, forever searching and listening for any sound coming from the ground that would betray its vole prey. Suddenly it checked its flight, stalled, hovered on slowly beating wings and dropped into some rough grass. It stood for a few seconds, twisting its large bulbous head this way and that, as if surprised it had missed its prey. A comical 'where did it go' moment.


The few seconds on the ground were sufficient for the owl to recognise it had been unsuccessful and it rose on rounded wings, the undersides gleaming white in the sun, to resume its search. It covered the whole area at least twice, relentless and thorough in its quest and then, once more  twisted in mid flight, hovered for a momentary check before dropping, with feet and legs held together and wings held outwards until the very last moment, before landing in the grass at speed, the wings now held aloft, clear of the coarse grass and herbage. Sadly this attempt also met with failure.






The owl rose into the air once more and continued its quest, now moving further away from me, to the east. I moved closer to where it was hunting and once more it dived into the grass. I could just discern its white head in the grass before it was inclined downwards. Had there been a successful kill?

The owl was on the ground for almost a minute, invisible in the long grass and then rose and wheeled up into the air to fly past me at no great distance and this time there was a small brown carcase grasped in its talons. The owl, had at last been successful and flew purposefully west, heading for somewhere secure to eat its meal and I lost sight of it in the glare of the sun. I waited for half an hour but there was to be no return. 

The sun was now declining perceptibly in the still cloudless sky and shadows were drawing across a land preparing for dusk. I left for home.

You can just see the tiny vole held in the owl's talon
Tuesday's weather was similar to yesterday, very cold and with the sun continuing to shine, unhindered by any cloud. I decided on another afternoon of watching the Barn Owls. After all, this weather would not last and here was an opportunity to make the most of this unexpected break from rain, cloud and wind. I arrived at Farmoor at just before two in the afternoon and stood expectantly, awaiting the arrival of the Barn Owl. I was still waiting an hour later. I could see no difference between the conditions today to those of yesterday but obviously the owl did.

However, during that fruitless hour, I witnessed a most unexpeced thing and one I never thought to see, least of all at Farmoor. Looking across, I could see the river that swept in a large bend round the water meadows to run towards the lock keeper's house and moored longboats, whilst the main flow went through a weir that controls the river's flow. I noticed two adult Mute Swans on the river that I thought were renewing their pair bond.They were breast to breast, with their long sinuous necks almost entwined but beating each other with the bend in their wings. I looked more closely and quickly realised my error, they were two adult male swans fighting. Barging with breast, half spread wings and neck against each other. A trial of strength if you like. At first they were some distance upstream but were being carried closer on the river's current until the beating of their wings was clearly audible. Neither appeared willing to give way and first one would be in the ascendancy and then the other appeared to get the better of its rival. They were being followed by a female that was presumably paired to one of the swans. She  kept making a high pitched squeak as if in concern at what was happening. Each male swan's strategy was to barge and bludgeon its opponent into submission, occasionally using their bills to peck at each other but mainly using brute force of body and wing to try and make the other submit. This continued for at least fifteen minutes, as all the time they came downriver on the current, the two swans, never apart, locked in deadly combat. I expected one of the swans to eventually accept defeat but in this case neither was willing to desist, concede and make its escape. It looked like a fight to the death and indeed that is what it was. The two swans still locked in combat, passed behind a line of bushes on the river bank but when they emerged on the other side I could see one swan was floating lifeless, its neck and head submerged below the water whilst the victorious swan still barged and beat at its lifeless body, following it as far as the weir where the dead swan was carried on the rushing water through the weir and away downstream.

The female swan hung about upriver of the weir still emitting her strange cries of concern. The victorious male swan that had followed the dead swan as far as the weir returned to join his mate and both pushed steadily against the current, swimming upriver and the last I saw of them was the male swan standing and preening on some flattened rushes, as if nothing untoward had happened.

I looked up this behaviour in BWP (Birds of The Western Palearctic) and it informed me that what I had witnessed is a very rare occurrence but not unknown and the usual victor is the swan already holding the territory. I certainly will regard Mute Swans differently from now onwards!

At just after three in the afternoon a Barn Owl floated behind me. Initially looking in the wrong direction, I almost missed it as it flew in the sky above the reservoir bank but it turned and came towards me, dropping down, before turning once again and rather than  quartering the same ground as yesterday seemed to prefer the reservoir's bank of manicured grass, briefly perching on the barbed wire fence surrounding the reservoir's outer perimeter.








It took off again and shortly afterwards dropped like a stone into the long grass behind some hawthorns but when I went to investigate where it had landed,  it flew up from almost in front of me. Both of us surprised. I pointed the camera at the owl, hoped my settings were right and pressed the shutter. The owl could obviously hear the camera clicks and gently veered away to hunt further from me and not long afterwards it caught a vole and flew, as yesterday, westwards and was gone.





I assumed this was the finale and there would be no more Barn Owl activity this afternoon.  I called Dai and we were talking on the phone when to my delight another Barn Owl, or was it the same one, flew past me.

'Sorry Dai. The Barn Owl. It's back. Must go' I exclaimed and terminated the call. Dai would understand. I followed the owl's progress and this time it gave me the closest views as it hunted over the rough grassland and scrub of dead umbellifers.



A creature made even more beautiful by the bright sun, its white underparts almost luminescent and its upperparts and wings shining, golden buff suffused with much grey, whilst three separate lines of black spots were strung like pearls across its spread wings. Its buff and grey upperparts made it surprisingly hard to see against the scrub and rough grassland it flew over, although its white underparts and large size plainly stood out as it passed before a background of hawthorns






Like the previous owl, it was quickly successful in capturing a vole and after no more than ten minutes it too departed to the west. I lost sight of it as it flew through the trees by the river.

I waited but I knew it was unlikely that I would see another Barn Owl today and so it proved.

  3. Yup - red in beak & wing, but not half as brutal as a Tory Government. Wish I could get over to see the barnies, but as you know I'm tied up all this weekend (tho to be fair, tomorrow is Jane & my trip to - hopefully - see the black-throated thrush....) x
