One of us had an absolutely astonishing month, and it certainly wasn’t me!  Jonny found a Swallow roost which yielded an excellent 182 birds ringed in four sessions.  Not content with that excellent Swallow catch, he managed to include four Sand Martins and three House Martins during those sessions. If that wasn’t good enough, he had a couple of, frankly astonishing, catches at two of his farmland sites, with over 400 birds caught in just two sessions.  One of those sessions was boosted by a phenomenal catch of 161 Goldfinches..

Actually, two of the team had a great month: my current longest serving trainee Ellie has been awarded her A-permit!  It is thoroughly well-deserved, having put up with me as her trainer since January 2015.

Overall we caught fewer birds, but in fewer sessions, so the averages were all higher. 

Missing from the list this year were Bullfinch, Garden Warbler, Nightjar, Tree Sparrow or Woodpigeon.  Added to the list compared with last September were Linnet, Moorhen, Pied Wagtail, Sand Martin, Stock Dove, Stonechat and Whinchat.

The Moorhen is the only one ever ringed at Langford Lakes, according to the data in the online database.

The Sand Martins are the first caught since the group came into its current form at the beginning of 2013.

After a three year absence, I was pleased to catch four Whinchat back at Blakehill Farm.  Three of them essentially rescued my ringing demonstration for the Swindon Wildlife Group on the 7th of the month. It turned a small catch, although with a reasonable variety of some interesting birds, into a session that the attendees definitely appreciated.  

The Stonechat catch was interesting.  Two were caught at Langford Lakes: the only other catch of Stonechat at Langford Lakes was one in October last year.  Langford Lakes is certainly delivering now it is being surveyed more frequently.

The four Stonechat caught at Blakehill raise an interesting question. In February of this year we caught and ringed a male and a female at Blakehill Farm.  The first that we have caught Robin Griffiths, who spends his time as volunteer warden at Ravensroost, and surveying all of the sites around the Cricklade / Braydon Forest area, noticed that there were two breeding pairs of Stonechat at Blakehill, despite there being virtually no standard Stonechat habitat at the site. He also noted that both pairs bred successfully.  Although we cannot be sure if we have, it would be great if we have managed to ring some of this year’s local offspring (three were juveniles).

There were some rather large falls in the catch of some of the commoner species.  Blackcap numbers were well down at 160 against 382 and Whitethroat were down at 7 against 25.  Of resident species, Blackbird were at 8 against 18, Blue Tit were down to 85 from 165, Robin 42 from 65. As well as the Goldfinch catch, the Greenfinches also showed a good increase at 39 from 6.

So, a pretty good month all round.  It is shaping up to be a really good year again:

For the third quarter in a row we have exceeded our previous best numbers. 

Hopefully we will get some decent weather in October and keep the run going.

It has been a difficult month in my neck of the woods: too much rain and far too windy, far too often. With Jonny Cooper, with sites just 20 miles or so further south than mine, getting fantastic results on his farmland sites: 234 birds from 15 species on Tuesday (47 Meadow Pipits and an astonishing 148 Goldfinches) and 182 birds from 11 species on Wednesday (129 Meadow Pipits), I was desperate to find out what we could get at Blakehill Farm for the end of September. Autumn passage is always the most interesting time at Blakehill, but the topography is such that we cannot work there if it is other than close to flat calm.

So far this month we have had fairly poor results on the Chelworth side of Blakehill, with a total of 58 birds from 14 species. To be fair, that was mainly down to the ringing demonstration on the 7^th producing only 14 birds (even if three of them were our first Whinchats since 2021). 44 birds on my solo session on the 19^th was definitely an improvement. There have been some definite highlights: three Whinchat and two Stonechat (our first September catches since 2020), a Sedge Warbler (only our fifth at this site), another Redstart (our fourth, making it our best year for the species), 19 Chiffchaff and 13 Meadow Pipit. I was hoping for a better catch this morning.

Today’s forecast was for it to be dry, and to have fairly low wind speeds, a base of 4 to 5mph, with gusts getting up to 15mph by 11:30. I was joined for the morning by David, Sarah and the entire Childs family, so I thought we could set couple of additional nets. This is what we set up:

Although the weather started out as forecast, unfortunately the wind got up much earlier, at about 10:00, and interfered with some of the nets, particularly rides 1, 2 and 3 and made taking down ride 6 difficult as David, Sarah and I spent a pleasant 10 minutes extracting it from Blackthorn. In fact, we closed ride 1 early as birds were flying out and around it constantly but, because of the billowing of the net, just were not being caught. It also affected the Mipit triangle: it started well, but fell away as the wind increased: we could have 20 or so birds within the triangle but, if we were lucky, catch one or two.

The session started really well, with the first two rounds producing 30 birds, but unfortunately fell away quite quickly. The dogleg ride 4 finally, after two empty sessions, produced a few birds, as did rides 5,6 and 7. Rides 6 and 7 caught a good haul of Reed Bunting in round one, including one retrap that is not on our rings. I look forward to finding out where it was ringed.

The list for the day was: Blue Tit [1]; Great Tit [2]; Wren (2); Dunnock [1]; Meadow Pipit 6[10]; Robin [1]; Stonechat 1[1]; Whinchat [1]; Chiffchaff [8]; Reed Bunting [10](1). Totals: 7 adults ringed from 2 species, 35 juveniles ringed from 9 species and 3 retraps caught from 2 species, making 45 birds processed from 10 species.

I am pretty sure that, had the wind not got up, we would have caught more Meadow Pipits than we did: possibly doubling the number, but it was good to get out and add to our totals for Meadow Pipit and, particularly, Stonechat and Whinchat. This year, for the first time ever recorded, Stonechat have nested and successfully bred at Blakehill Farm. There were two nests and two young fledged – and we have ringed four Stonechat so far this autumn: three juveniles and one adult. I would love to know if we have been lucky enough to catch some of the birds that fledged at the site.

With the wind getting stronger, and the bird numbers falling right away, we decided to start taking down at 11:00, with ride 1. We did have a couple of birds to process after that. So we took down rides 4 to 7, before removing the Mipit triangle and ride 2, with three final birds to process before leaving: two more Meadow Pipits and one more Reed Bunting. That made it our third best September catch of Reed Bunting at 15 for the month, behind 19 in 2016 and 17 in 2019.

So, it was our best catch of the month at Blakehill Farm: by one bird! We had everything packed away and left site soon after midday. Hopefully we will get the chance to get back to the site within the first couple of weeks of October and add to our Meadow Pipit total. Now, if I can also find the opportunity to get a session or two on the other side of the site within those two weeks as well I would be well satisfied.

One final point: the end of our session was disrupted by someone flying their model aeroplane out over the plateau. There is a model plane club that has permission to use a number of fields over which to fly their toys, but the undertaking the club made in their agreement with the landowners is that they will not fly them over the plateau, so that they don’t disturb the cattle, sheep or wildlife. I drove round to where he was parked up and, politely, asked him not to fly the plane over the plateau. He was as arrogant about it as one would expect from someone who knows that they are in the wrong, but he did pack up, thankfully.

After the deluge preventing any ringing since last Wednesday, and with the rest of this week looking wet and windy, today was the only day that looked possible for any ringing in the near future. It was supposedly going to be windy, with the wind coming from the north-west, so it was going to have to be a woodland site. I haven’t been in Ravensroost Wood since the first week of July, so I decided that would be the place to go. As regular readers know, with the exception of the Firs, our catches in woodlands this summer have been disappointingly small. Ravensroost Wood, for example, has averaged just 17 birds per session. However, it was due for a visit.

I was joined by Rosie and Miranda to help set up at 7:00. As Miranda was walking down to where we were to start setting the nets she saw a small group of six thrush sized birds on the main path: she was certain that they were Redwing. Since our records for Redwing began, in December 2000, out of 3,476 of the species processed, none have been processed in September. However, I put on our lure for Redwing and, at about 9:30, a thrush-like bird hit the net. I rushed off to take it out but, unfortunately, a couple were walking their dogs down the path, and it is possible that they spooked the bird, which managed to extricate itself and fly off. The couple were not doing anything wrong: the dogs were on short leads and under control, it was just unfortunate timing. However, they know their birds and they told us that it was a Redwing! The earliest date that we have ever caught a Redwing was the 6^th October 2010.

The reason for the unfortunate interaction was my decision to set the nets down the main ride. This was because the side tracks are horrendously overgrown, due to weather, illness, etc, I haven’t had the time to get them cleared, so we decided to just set up along the main track. Our thoughts were that, with the weather having been so foul, and Ravensroost known to get very mucky underfoot, there would not be many people in the wood today. With just three pairs and one individual passing through, all with their dogs on leads, it was the right decision.

Rosie had to leave early, and I mean early: at 7:45, just after the nets were up and open. She had time to extract a Wren, the first bird of the morning, but not time to process it. As Rosie left, Laura arrived, after having done the school run! She extracted a Nuthatch (yes, another one) as she wandered up to the ringing station from the car park.

The first round proper flattered to deceive: nine birds from seven species. However, after that we did not catch another bird for nearly two hours! That was a single bird, 30 minutes after that we caught four more, all Long-tailed Tits and, as we started to shut the nets, we caught another two.

The list for the session was: Nuthatch {1}; Blue Tit 1[1]; Great Tit [1]; Coal Tit (1); Marsh Tit [1]; Long-tailed Tit {6}(1); Wren [1]; Robin (1); Chiffchaff [2]; Goldcrest [2]. Totals 7 unaged bird ringed from 2 species, 1 adult ringed, 8 juveniles ringed from 6 species and 3 birds retrapped from 3 species, making 19 birds processed from 10 species. Nice variety, if not great numbers. If only that Redwing had stayed in the net, and the Treecreeper that was running up the Oak tree just behind the net had got itself caught, it would have been a very decent session.

Annoyingly: the wind that was forecast by all of the forecasters did not materialise until we started packing up at 11:30, so we could have gone somewhere that was guaranteed to be more productive. Fortunately, tomorrow’s forecast has changed for the better, so I will be heading off to Blakehill Farm to try and catch a few more Meadow Pipits and any autumn migrants that might be passing through.
