A Big Day in Oxfordshire

It began over a Christmas meal. Dave Lowe talking about trying to break the record for the number of bird species seen in a 24 hour period in Oxfordshire. Pete Roby, Steve Roby and Jon Uren set the record of 114 species on a May day some years ago. They were sitting near Badger, Dave, Andy Last and myself. I don’t remember volunteering to be in on the record attempt that evening, though now I look back some of the post parandial conversation did follow an interview format. By the end of the meal, a record attempt this year seemed quite likely. By the end of February, two other teams of local birders had registered their interest. A date, chosen by Dave, was agreed. There would be three teams, all competing to see who could record the most bird species in the county on Saturday 29th April 2017.

The Greylags, a superb typically self-deprecating name for the team of the Robys and Jon Uren, were the current record holders and have as much experience of Oxon Big Days as anybody. If not more so.  The Biffin Boys are Ewan Urquhart, Tom Wickens and Mark Merritt. A team heavy with recent local birding knowledge and experience. Indeed, Tom Wickens, had recorded 101 species single-handledly the weekend before on foot, covering some 47 miles. This Herculean effort set an extremely high bar for the Big Day weekend. Our team – The Acronaughts – were Badger, Dave Lowe, Andy Last and myself. Like God, in the beginning our plans were immaculate. We had spreadsheets of target species, potential and probable sites and agreed dates for carrying out pre-Big Day surveys of interesting areas. But the Lord also “knows all human plans; he knows that they are futile” (Psalm 94:11). And so it proved to be the case. Five days before the Big Day, Dave was still in South Africa, Andy was in Norfolk and Badger in Texas. Our only reconnaissance trip consisted of me spending of two hours on the downs with Andy one evening, which was really informative. We decided we would not begin our Big Day there. Indeed, so caught up in external events were we, that Badger realised he was only due to return to the UK the night before the Big Day. Badger, aka Jason, felt that he would would have to pull out, being up for 24 hours is tough enough without adding extra jetlag. So four became three. The the biggest loss was that I was deprived of the opportunity to use the team name Jason and the Acronaughts. There would be no Jason.

Dave arrived at my house, with Andy, at 3:30am yesterday morning. We drove to Otmoor and incredibly there was another car heading down the access road from Beckley – the Baffin Boys! So two teams were starting at the same place, at exactly the same time. We greeted each other and wished them luck, but neither team really wanted to be out birding next to another team, so we kept our respective distances. Our first bird was Tawny Owl, a hooting male, at 03:48. We walked out onto Otmoor in the dark, with singing and calling birds all around us: alarm calling Redshanks, singing Sedge and Grasshopper Warblers, drumming Snipe, calling Curlews. It was atmospheric and exciting. We settled in at the first screen and let the Baffin Boys head past to the second screen. We could just about identify some of the dark shapes out on the water: Coots, Moorhens. Other birds were beginning to wake and sing – Blackbirds, Robins. Then more footsteps and in walked The Greylags! There was much amusement, with all three teams now watching the same area of reedbed on the same reserve. Great minds obviously all thought alike. They left shortly afterwards to go up to the second screen. In the true spirit of bird racing, we checked that they had not stolen any of our optics and then we concentrated on the serious business of breaking their record. One of the original rules of a bird race is that at least three members of a team of four have to see or hear a bird for it to count on the list. This creates a dilemma if one member of the team fails to hear a certain squeak. Or in our case, a certain squeal. A Water Rail squealed from deep within the reedbed, but only Andy and myself heard the call. “Don’t worry, we are bound to hear another” I reassure Dave.

We were picking up new species quickly and gradually at around 5am it began to get light. We knew we needed a glimpse of a Bittern or of the still wintering Hen Harrier, to add some quality birds to our growing list of common species. Finally the sun rose, flooding the reedbed with a gorgeous orange light:

At precisely the time I was taking the above picture, 2 Bitterns flew into the reedbed, seen by The Greylags but unseen by us. Marsh Harriers began hunting, an Oystercatcher flew over our screen. After two hours at reedbed, we decided to check out the rest of the reserve. Although the day was only just beginning, we felt we were behind. We had not seen either Bittern or Hen Harrier. This feeling would remain with us for the rest of the day. We hit 50 species at 06:30, without actually seeing anything of note. Recording the next 50 species would take another 14.5 hours. Welcome to Oxfordshire!

We walked around to the Noke side of the reserve, an area known for holding Wheatears and Whinchats in the spring and our only solid site for these species in our day. We scanned the fences, the fields, the sheep, the roads, pretty much everything. But there were no chats at Noke. This was a bodyblow for a good total. We had a nice lift as we headed along the main track, a Water Rail squealed and we all heard it. “I have never been so relieved to hear the sound of a pig being slaughtered in all my life!” said Dave. Then we met Pete Barker, Mark Chivers and others on the main track. They confirmed that the Greylags had seen Bittern. We WERE officially behind. We walked over to Long Meadow for a chance encounter with Redstart. Long Meadow was a long shot, too long for us. No Redstart, or indeed any chat of any kind. We left Otmoor with 63 species under our belt, with all the likely ducks and all ten species of warbler recorded. This looked good on paper, but we felt it was already not enough. As we drove out of the reserve car park we saw Mark Merritt, one of the Biffin Boys, walking towards us up the road. Now, we are all very fond of Mark, but as he was officially the opposition, we felt we should modify our behaviour towards him. So Dave swerved the car towards him, as if to run him off the road and I waved a clenched fist from the rear back window as we flashed past. Unfortunately I am not sure Mark recognised Dave’s car or any its passengers as we sped past, so apologies to you Mark for the attempted murder – its just a Big Day, you know! We picked up House Sparrow and Collared Dove as we passed through Islip and made our way to Farmoor Reservoir.

Farmoor has been home to a Bonaparte’s Gull, a rare visitor to the county, for the last couple of weeks. We saw Dai Johns leaving the reservoir and he confirmed that the gull was still present first thing. The change in habitat led to a rapid increase in new species as we saw a selection of late April migrants and water birds: all three wagtails, plus White Wagtail; all the hirundines, plus Swift; Common Sandpipers and Dunlin. But where was our American visitor? We scoured the south side of FII, turning up the female Goosander…

.. and a few of the more expected bird species:

At 10am a sailing competition started taking place, disturbing many of the birds on the larger side of reservoir. We gradually had to accept that the Bonaparte’s Gull had left with most of the other Black-headed Gulls. Reflecting back, we spent too long at Farmoor searching for one species. As we left I said to Andy and Dave “I can’t believe we have not seen a Bonaparte’s Gull“. To which Dave replied “And that is the first time that line has ever been used on an Oxfordshire Big Day“. Below, the stinking headless corpse of a dead Cormorant. Somehow that summed up our time at Farmoor:

From Farmoor, to Dix Pit:

There were large numbers of Black-headed Gulls here, all feeding low over the water, picking up insects. It felt completely reasonably that the Bonaparte’s Gull could be here, feeding with the local gulls. And we were almost right, it was located at Rushy Common later in the afternoon. Scanning through the Black-headed Gull flock produced one of the moments of the day. I was checking gulls that were flying past into a small bay, hidden behind vegetation on the shore of the gravel pit. Suddenly, a small gull with a black “M” pattern on its upper wing flies through my binocular view, before instantly being obscured by a bush. “I’ve just had a small gull with a black carpal bar fly into the bay” I call to Dave and Andy. We check each gull as it emerges from the bay. Andy gets there first: “Ah! Little Gull!”.

A cracking first winter Little Gull, our own find and a nice little lift for our morale. The bird also had a nice pink flush to the breast. Whilst the image below is not in focus, it does show the pink colouration nicely:

We leave Dix Pit for nearby Rushy Common:

Green Sandpiper was reported from this site only 24 hours previoulsy. We check every wader we come across, but they are all either Little Ringed Plovers or Common Sandpipers. Dave then picks out another Little Gull perched out on the sandy island. Could this be our bird of earlier from Dix Pit, which did vanish a few minutes after we first located it? The picture below is massively cropped, so detail is lacking. But to me it seems as if the pattern of grey on the crown is rather more solid at the back of the head compared with the Dix Pit bird:

We may never know. Either way, after working Rushy Common and then Pit 60 (where disappointingly there were no Great White Egrets, another first time that line has been used on an Oxfordshire Bird Race) we had 85 species by early afternoon. By now we have been up since 3am, but we still had energy and were feeling focused. We were just aware that we lacked the quality big birds that we needed to get a really good total. Our rather random morning was captured perfectly by the picture below:

Oxfordshire birding at its best, a random bird in a bizarre location: Egyptian Goose up a tree at Rushy Common!  Realising that we are a couple of hours behind our rather ambitious schedule, we drive into the Chilterns for some hill and woodland species.

Above, Andy scanning from Linkey Down. Ever since I wrote this article at the end of the March monthly review on the Oxon Birding Blog, noting Linkey Down’s reputation as a reliable site for Ring Ouzel in spring, the site has failed to produce the goods. There have been a couple of reports of Ring Ouzels being present (by a member of Team Greylag, no doubt in Big Day planning mode) but this year at least, reports have been very thin on the ground. Nevertheless, as we walk to Linkey Down, Andy and I agree that strangely we have a positive feeling about getting Ring Ouzel today. A mood that persists despite passing a woman leaving who says that there are no Ring Ouzels present. Has she been paid by The Greylags? We sit and scan the lower slopes. Suddenly a loud harsh “tack, tack, tack” call, followed by a burst of song, comes from a tree above us. “Hello, that’s a Ring Ouzel!” I instinctively call out.  I locate a dark thrush at the back of the tree. It has a pale wing panel and pale fringes to the flank feathers. Even better, it turns around slightly to reveal the edge of a mighty white collar: it is a singing male Ring Ouzel. With a report of Redwing singing in the county in March, at least 5 species of thrush have now been heard singing in Oxfordshire this year. Is this a record? The picture below is certainly a record shot, though you can make out the key features. Nevertheless, it is another species on our list:

Then into the woods at a site in the south of the county. The list pushes on slowly, with Treecreeper, Coal Tit and Marsh Tit all being added. The highlight was a superb Firecrest:

Above, Andy; below Dave, both birding in bluebells:

Our woodland peace is broken by bird news. Steve Roby posts on the Oxon Birding Blog that Team Greylag have found a Wood Sandpiper at Rushy Common. Our tortured screams cut through the sunshine and bluebells. We fall to the ground writhing in birding pain (metaphorically, but only just). We were there 90 minutes ago and specifically checked every wader in our hunt for Green Sandpiper. Why did we not find that bird?! It must have just flown in. Not only is this a great find, but we can feel Team Greylag extending their lead.

Being behind schedule was finally beginning to catch up with us. We planned to head north to Banbury and/or south to Henley, depending on time. We now had time for neither. It was 5pm, we had 3.5 hours of light left and we realised that we would now struggle to get much past 100 species. Now 100 species in a day in Oxfordshire is a good total, but not a record breaking total. We convene a council of war and make our decisions. Our early failure to see any chats or Wheatear was coming back to haunt us. And we still had not all seen Mistle Thrush. We decide to head back to Otmoor, as there are five potential new species there for us and that still leaves us time to finish in light on the Oxfordshire downs.

Otmoor is bathed in blue skies and beautiful late afternoon light. The common species, simply shimmer in colour:

Unfortunately, we are not interested in those common species. We claw back Mistle Thrush and Wheatear at Noke (really, where were they at dawn?) but still do not connect with Bittern in or above the reedbeds. At 6:30pm Dave calls time, we have to get to the car and drive south.

We end our first Big Day at Churn, above Blewberry in southern Oxfordshire. We rapidly add Grey Partridge and Corn Bunting. A Little Owl on the posts above the railway cutting becomes species 100 at 8pm. We quietly high five, but we reflect at the time that we are probably 5 to 10 species short. Which, as it turns out, was exactly right. The Greylags recorded an impressive 110 species, just pipping The Biffin Boys with an excellent 109 species. We finished with 104 species seen by the group as a whole.

It was great fun and I loved every minute of the day. Dave and Andy were superb company and are great birders. We all participated, all found new species and helped get the others others onto them. As a group we worked well together. It was not as physically exhausting as I anticipated, though we did walk 15.2 miles during the day and were birding for nearly 18 hours. So much seems to depend on how much migration occurs on the day. Saturday 29th April was a very average day. Had we chosen today, 30th April 2017, for our Big Day, then the county record could have fallen, as an influx of waders has been reported across the county. Migration events cannot be predicted, there is a large slice of luck associated with them. However, our virtual lack of planning counted against us. Next time, we need a couple of weeks with regular reconnaissance  trips before The Day. Our schedule was, with the benefit of hindsight, overly ambitious. Congratulations to The Greylags, temporary Big Day winners (till next year!) and to The Biffin Boys. We look forward to sharing your experiences of the 2017 Big Day over a drink sometime soon. And then beating you next year.

  1. Excellent report and made me feel like rushing out and doing a 100 plus species bird day here in Norfolk — still at least I could finish mid afternoon. Ha. Cracking effort as ever Mr B and very jealous of your superb day
