In the annual cycle of life and work at Forvie, the first week of March represents the beginning of the ‘crazy season’. From this point onwards, it’ll be all hands on deck for six months of mayhem, much of which revolves around the Reserve’s breeding birds. Heavy metallers Motorhead may have had ‘no sleep till Hammersmith’, but for us it’ll be ‘no sleep till September’ – or at least that’s how it feels.
The opening ceremony to this prolonged and vibrant festival of life is the ‘tern fence week’, when we begin work on the electric fence which will protect – or so we hope – Forvie’s ternery from the attentions of predators during the coming summer. It’s a huge milestone in the year here, and invariably requires a good deal of hard yakka – and a genuine team effort.

The electric fence encloses an area of about five hectares, comprising a mosaic of low dunes, short grassland, dense stands of nettles and willowherb, and patches of bare sand and shingle. The varied habitats within the enclosure suit a corresponding variety of nesting birds, with some species favouring open ground (Little Tern, Sandwich Tern, Oystercatcher), some choosing dense cover (Eider, Gadwall, Grey Partridge), and others favouring the short tussocky grassland in between (Black-headed Gull, Arctic Tern, Common Tern). Each species has its own particular niche, and we try to cater for each of them when preparing the enclosure at the start of the season.
With much of the area covered in a thick thatch of Marram Grass, the first job of ‘tern fence week’ is the laborious process of cutting a ride through the dense vegetation to accommodate the fence.


Located as it is at the southernmost tip of the Reserve, access to the ternery by vehicle is dependent upon favourable tides. With the winter’s storms having cut off our beach access at Rockend, our only remaining vehicle route to the ternery is along the estuary foreshore at low tide. However, this week’s tide times were far from ideal, and on Monday I was unable to get down to the ternery until 3pm. Consequently it was a case of having to use all the available daylight; I eventually had to admit defeat at about 6pm, by which point I could have done with a set of headlights on the brushcutter.

Indeed, by the time I had loaded the brushcutter and its accoutrements into the back of the pickup truck, the moon had already risen over the dunes on the eastern horizon.

With the ride-cutting complete, it was then a case of shifting the requisite half-ton of fencing materials from the workshop to the ternery. This was done in two instalments, for the simple reason that it doesn’t all fit in the truck in one go. The 2026 edition of the ternery fence necessitates no fewer than twenty-two rolls of mesh netting, which will stretch to a whopping 1,100 metres, plus an additional forty-odd bundles of plastic insulating poles which will eventually carry the 2,200 metres of steel wire. That’s a lot of lifting and shifting – and once again we had to work around some awkward tide times, with the two drop-offs happening first thing and last thing in the working day.


With all the materials now in-situ and ready to go, Wednesday saw us assemble a crack team of friends, volunteers and colleagues (they’re all the same thing really!) for the mammoth task of turning the heap of components into something resembling a functioning fence. The team comprised a mixture of old hands and new faces, and we started off with the usual ‘team talk’ and introductions. As an ice-breaker, I usually ask folk to say who they are, where they’re from, and a fun fact about themselves. In case you’re wondering, mine went as follows: Daryl; estate worker and dogsbody here at Forvie; I once dislocated my shoulder without spilling my pint (true story by the way).

There then followed a masterclass (ahem!) in how to unpack and erect each roll of mesh netting. While it does a great job for us, I’m convinced the stuff must have been designed and manufactured by the devil himself, as it’s infuriating stuff to work with. Scratchy, catchy and invariably awkward to handle, it snags itself on anything and everything with which it comes into contact – including the treads of your boots, the zips on your jacket and the ends of your wits.

The difficulties of the day weren’t just confined to recalcitrant fencing materials. A perennial problem is knowing what to fence in and what to leave out, particularly in the extremely dynamic landscape along the northern edge of the enclosure. We always aim to fence in as much exposed shingle as we can, as this is first-rate Little Tern habitat. However, we’re always trying to second-guess which areas the birds will choose for nesting, and how the wind and weather might alter the landscape during the course of the season; this involves a lot of educated guesswork and considerable crossing of fingers. Get it wrong, and the penalties can range from a six-month maintenance headache to the complete failure of the breeding birds in the coming season. No pressure then.

Ultimately you have to roll the loaded dice, and hope to goodness that you’ve made the right choice. I shall report back in August – wish us all luck.

With the North-east having enjoyed some fine spring weather at times in the past few days, our Black-headed Gulls have been quick out of the blocks this year, and by Tuesday morning they were already prospecting on the colony. This fence can’t go up a moment too soon!

Likewise our Ringed Plovers, who are already occupying the shingle areas; on Wednesday they kept a weather eye on us as we worked, as if making sure we were getting things right. The lives of their offspring, like so many others, will depend on the effectiveness (or otherwise) of the finished fence.

We were also kept company by a single Snow Bunting – cue another one of those dreadful ‘phone-camera-through-the-binoculars’ photographs…

What d’you mean, you couldn’t see it???

OK, let’s zoom in a bit then… see, I told you it was there!

That’s quite enough of that rubbish – here’s a photo where you can actually see what a Snow Bunting looks like. Thank goodness there are people around with better photographic skills than mine.

The week ended with a couple more fine spring days, and we were able to glimpse that rare phenomenon that had eluded us for the first two months of the year: a sunset over the estuary. I was that busy gawping at it that I forgot to get a photo until after the sun had actually dropped. That’s what rarities do to a naturalist though.

So that’s week one of the crazy season done then – just another twenty-five to go…
