27th July 2014 - Moulden Hill & Nightingale Wood

MOULDEN HILL

Paul W and I enjoyed a very pleasant morning by the canal, it was nothing like the excellence of the day before but a good day to do some one on one training. Two Grasshopper Warblers started the day off nicely along with a decent selection of warblers. This site is a bit of a Bullfinch hotspot and today we ringed 5. We re-encountered a juvenile Willow Warbler that we ringed at Swindon STW (1 mile south) on 13th July.
 
Phil dropped by for a chat which was great and we discussed future rides at this promising site.
 
In the evening I went out nest checking and ringed 50 Tree Sparrow pulli and 23 Swallow pulli. The day total of 138 ringed was pretty reasonable. MP, PW

NIGHTINGALE WOOD 27th & 28th

Two sessions at Nightingale Wood, one at the Roves Farm side that has two small lakes, a small reedbed and willow plantations, and the other site in the wood including the adjacent meadow.

Lots of 3J warblers made up almost all of the catches with a great deal of the migrants on their way through which was shown up by the virtual lack of retraps on each day. Roves Farm on Sunday was dominated by Garden Warbler's which must have had an amazing breeding season with 11 ringed followed by another four on Monday in the wood. This takes me on to 78 new for the year with a staggering 53 ringed in just the last 3 weeks.

The reedbed produced 4 new Sedge Warbler's and 3 new Reed Warbler's which is not bad for something you could spit accross. Willow Warbler's are also becoming more obvious with many calling or giving sub-song although we only caught 8 of them.

The best two birds from the two sessions we both from the woodland side with a Grasshopper Warbler in the first net round and a Green Woodpecker in the last.

Another two productive mornings with 136 new and 8 retraps. GD/PD

26th July 2014 - Salisbury Plain (centre) & Swindon STW CES session 9

SALISBURY PLAIN (CENTRE)

A third visit in 7 days for this site was on for the morning and with the current turnover of migrating warblers high we were holping for another good catch and were not disappointed.

The very first two birds out of the nets were chats from the chat valley net in the form of another Whinchat and a Wheatear. The Wheatear was a particularly good bird for us as we only average one every other year so not suprisingly it was a ringing tick for trainee Andrew.

DSCF2505

Warbler numbers began to pick up and we soon caught a good mix of all the common species including 6 Sedge Warbler's and 5 Reed Warbler's on their way out of the country and a good catch for this upland chalk scrub habitat. Two new juvenile Grasshopper Warbler's were also added along with out first new Lesser Whitethroat at this site for over a month. The chat net came up trumps with a third chat species in the form of a Redstart.

While taking down the nets after a successful morning we encounted the Starling flock again which had increased to over 1000 birds. Thankfully the double 60 only had 12 in in but we could hear the noise from the main flock in the bushes by ou next net. Thankfully again we missed the main flock but caught 4 more but if the net had been another 30 feet longer things would have been interesting.

The final bird out of the nets was a rather nice 3J Tree Pipit.

SWINDON STW CES SESSION 9

The Scientific Arm of the NWRG completed Visit 9 of the Constant Effort Site at Swindon STW. Once again the site showed just how amazing it is, providing us with a diversity of species that no other local site can match, where else can a ringer experience 24 species in a morning in the UK? In addition to the CES nets, we put up ‘the bund’ as an extra net to re-encounter more of Simons Reed Warbler nestlings, this net set is amongst the most productive five-net set to be found anywhere. We also put up a couple of billy bonus wader nets before dawn.
 
The wader nets came up trumps with a new Green Sandpiper, this species is one of the hardest species to catch but we did even better by re-encountering one that we originally ringed as a first year in August 2010, once again demonstrating their non breeding site fidelity, and a very good example of longevity. 3 Magpies, a Woodpigeon and a Black Headed Gull added to the variety.
 
The passerine nets kept us occupied all morning and an influx of Garden Warblers was most welcome. Another two Lesser Whitethroats have us set up for one of our best ever years for this species compared with Grahams poor year for this species, showing how birds can fare so differently on a local level, just as Graham is having a good year for Garden Warbler whereas we are possibly set for our worst year for Garden Warbler.
 
Reed Warblers once again dominated the catch with 35 new and 22 re-encounters many of whom were ringed as nestlings on site and Sedge Warblers have started moving with 21 ringed. Not long before finishing we did a ringing demonstration to a group visiting the site as part of the programme of visits run by the Wiltshire Wildlife Trust and their excellent volunteer team. The visitors were treated to one of the two Kingfishers that we ringed during the morning and they got to see a a good variety of the birds that use the site.
 
Despite being busy, this was yet another great training morning with the team really starting to develop a greater understanding of the finer points of ageing and sexing but sadly the team once again left site clinging to the last strands of life due to starvation caused by Anna once again not bringing cake and apparently it is everyone else’s fault for not reminding her, I hope the team can survive long enough until the next CES session to enjoy the promised Chocolate and Beetroot Cake.
 
The total of 165 new and 46 re-encounters once again demonstrates what a productive breeding season we are enjoying. MP, PA, SW, AF, PW

22nd July 2014 - Salisbury Plain (centre)

Despite ringing this site as recently as two days ago I decided to give it another go which proved to be a good move. Migration this year is already well under way, far earlier than last year and this is being shown up in the large turnover of birds on this site. Today we caught very few retraps from the last few sessions so even the very recently fledged 3J's we have ringed this month are quickly moving on and being replaced by new birds.

The first bird of the morning out of the nets was a new adult Grasshopper Warbler and we soon caught two more. Blackcap's were particularly numerous with over 40 ringed but we also caught good numbers of Whitethroat's and Willow Warbler's but we also managed an impressive 11 new Garden Warbler's. On the down side we blanked yet again on Lesser Whitethroat so it looks like its going to take longer for this species to bounce back from the poor 2012 and 2013 breeding seasons.

One of the Garden Warbler's was in full wing moult which is not something I've come across before. It had also lost its tertials, was replacing all its tail and was in full body moult.

DSCF2500

The bonus net in the bottom of chat valley got us one more new Whinchat along with the usual Whitethroat's but one net round produced a net sagging with Starling's. By the time we extracted what we could we had 8 birds bagged up but at least double that had managed to roll out of the net. We considered ourselved lucky that the remaining 300 birds in the flock sat on some nearby bushes and stayed away from the net for the rest of the morning. We also caught out first Sedge Warbler of the year for this site, a sure sign that Autumn is coming.

An excellent morning with 127 new and 18 retraps. GD,OF

19th-20th July - Marlborough Downs, Salisbury Plain (east) & Salisbury Plain (centre)

MARLBOROUGH DOWNS & SALISBURY PLAIN (EAST)

 Despite the forecast for rain, thunder and lightning we still ventured out Saturday as the forecast showed enough gaps in the weather to enable us to continue with our nest monitoring. We popped into Marlborough STW but the House Martins were very high in the sky and there were 5 unringed Grey Wagtails but not enough birds worth trying for. We checked the Swallow site and ringed one brood but this visit inspired us to have a think about our monitoring here and we have decided that we would like it to be a key part of our summer work and so we are going to go for total monitoring which means ringing all the young and detailing where they are and then ringing the adults but trying to allocate them to the nest. The horse riders are all very interested so an end of year report is well worth the effort.

 
We tried to zip round the sparrow sites but then we saw a flock of c60 Tree Sparrows along with a few Corn Bunts and Linnets and couldn’t resist a little go but it yielded only a little but we did learn yet more lessons about setting nets in these open environments.
 
We then tried watching a Corn Bunting back to its nest and then the mother of all storms came along, flattened half of the crop, thoroughly cleaned the car and the lightning show all around was very impressive. Then as quickly as it came, it went and we spent the rest of the afternoon in blazing sunshine and then it started raining again just as we got home. MP, PA

I was on my own on Sunday which is always risky for the team because they think I catch the best birds when on my own, this is of course pure myth but they were taking a chance leaving me on the Salisbury Plain on my own. Sunday dawned quite weird with a cold but dry mist that caused a reasonable breeze that kept the insects down. The first round was decent and then it died completely until the last round when a few Whitethroats moved. It was clear today that most birds have stopped breeding there now and this was the first morning when virtually nothing sang. The only slight frustration was that there were 3 Redstarts on site but I only caught 1, but I will set a different net next time. Today saw the first juvenile Bullfinches which are always a pleasure to see.
 
60 new and 9 retraps is unspectacular but on a similar date last year we processed 49 new and 11 retraps. MP

The mist grey depressing start to the morning with a strong breeze that as at least double that forecast was matched with the number of birds we caught during the first 2 nets rounds with barely 10 new birds out of 17 nets.
 
However once it warmed up and the sun started breaking through the birds suddenly appeared and we had soon ringed good numbers of the common warbler species. Willow Warbler's were much in evidence with far more than on previous visits so they are obviously already on the move.
 
Interestingly out of the 94 new birds caught in the nets 59 of them were from just 3 nets so the birds today were obviously favouring just one parch of scrub.
 
A Nightingale was still present which gave a few alarm calls early on but wasn't caught and one of the Grasshopper Warblers briefly started up but no chats seemed to be on site.
 
In the end we had a decent moring with 99 new and 22 retraps. GD/PD

17th July 2014 - Pewsey Downs

After a couple of very successful sessions ringing Yellow Wagtails we were asked to consider trying a ‘retrap adults for survival’ project. We can only try this when it is very calm and even better overcast so we chose tonight which was fine but we didn’t bargain for the military aircraft that were testing how low they could fly before we put our nets up. A quick dash home from work, very fast turnaround and we were on the downs before 19:00.
 
Regardless of the unplanned military interruptions, the plan was set and so we put up two net sets and sat back to enjoy the beautiful evening.
 
Two rounds later we had a nice collection of Yellow Wagtails, a couple of Whitethroats and best of all our first ever juvenile Corn Bunting. MP, PA, NM, CH

11th-13th July 2014 - Salisbury Plain (centre), Marlborough Downs & Swindon STW CES session 8

SALISBURY PLAIN (centre)

After ringing 89 new birds as recently as Monday, including 25 new 3J Chiffchaff's we were hoping for lots more warblers.

We put up the usual nets including the billy bonus net for chats at the bottom of the valley. This was a good move as it caught us our first 4 Whinchat's of the year along with a 3JM Redstart. The main nets remained fairly busy all morning and the 3J warblers soon began to mount up. Chiffchaff's were off the menu to be replaced with good numbers of Blackcap and 34 new Whitethroat's which is our highest day total of the year so far.

We also caught the remaining adult female of the twp breeding pairs of Grasshopper Warbler and also a retrap Green Woodpecker we had originally ringed in May 2011.

Swallow and Stock Dove pulli made up the numbers once all the nets were down and we finished the morning with 116 new and 32 retraps. GD,PD,AB

11th-13th July - MARLBOROUGH DOWNS & SWINDON STW CES session 8

I haven’t had time to update our ringing activities until now because we have been too busy. Following a talk that I gave in Devon a few months ago, I arranged with Roger Short and Helen Williams a visit to teach us how to find Corn Bunting nests. As ever, with us this would involve other plans so we started with ringing a Linnet nest and then another attempt at the Yellow Wagtails. Everyone is very excited about our recent success so we had a big team out and so we did a few small improvements to our net set and we also put up a long line of nets elsewhere. The long line didn’t catch anything at all so lesson learnt but the ‘usual’ nets were excellent. We retrapped a juvenile Yellow Wagtail from last week but star of the show was a lovely juvenile Skylark. It is impossible to know how many Yellow Wagtails were present but there were a minimum of 50 and quite possibly 100. MP, PA, SW, JN, AM, RS, HW

Saturday saw us at the same place and the team split into two and though the place is teeming with Corn Buntings they were strangely elusive. ‘We’ ie Roger and Helen found one Corn Bunting nest, not in the crop as expected but in the grass verge by a horse gallop in exceptionally short grass and in the middle of tyre tracks which is frightening. The nest had four eggs and to say that we were delighted is an understatement as this is the first that we had seen and has been a long held desire to see. We observed lots of activity and we learnt a lot about behaviour and how we should find them in the future, even with this great breeding season it appears that Corn Buntings are only just laying eggs. This is all good stuff but it doesn’t get our ‘normal’ work done and so Biff and I left the others to it to go and ring some Swallow nestlings and Tree Sparrow pulli. We have nearly finished second brood Tree Sparrows and today we ringed our first third broods as well. MP, SW, JN, AM, RS, HW

Sunday was CES Visit 8 at Swindon STW and we were really pleased that Roger and Helen could join us to allow us to put up a few extra nets and with them as additional trainers we had the luxury of allowing Biff to ring birds all morning and also to extract more birds and he is making great progress. A Kingfisher in net 1 was the second for the year for that net and Roger and Helen were delighted to be able to ring Lesser Whitethroats because they don’t get them in Devon. Despite some very strong hints, Simon refused to make poor Roger and Helen a cup of tea and despite early season promises Anna once again failed to bring any cake, it’s just as well that Mr Prior was the provider of biscuits to ensure that we beat off starvation. We did well for re-encounters today with a five year old Dunnock, three year old Blackcap and Chiffchaff but undoubted star of the show caught in the extra net on the last net round of the day was a Reed Warbler originally ringed by yours truly on 2nd July 2006 making it a magnificent 8 years 11 days old and our oldest Reed Warbler to date, what a bird! 138 new and 53 retraps shows that this is looking like a pretty good breeding season, especially for Reed Warbler, Blackcap and Chiffchaff. MP, SW, AF, AM, RS, HW

6th July 2014 - Swindon STW CES session 7

With my phone buzzing all day Saturday we had a very large team out on Sunday for the seventh CES session of the year and we were joined by 13 year old Tom for his first experience of bird ringing. I hope we haven’t scared him off because we had a bit of a full on day with the whole site seemingly full of birds keeping the team busy all morning. We put up some extra nets to target the Reed Warbler pulli that Simon has been ringing during his nest recording efforts and we re-encountered 12 of the 24 that we have ringed so a 50% return rate is fantastic.
 
We re-encountered one of the Grasshopper Warbler nestlings that we ringed and that too was in an extra net so well worth the effort but we were quite surprised to catch a new female Grasshopper Warbler with a brood patch so we are not sure if she is from an unknown pair of if our male has changed partners or has an additional partner.
 
The day was dominated by three species: Reed Warbler with 22 new and 24 retrap, Chiffchaff with 33 new and Dunnock with 24 new and 12 retrap but any day when you catch 21 species of bird is pretty spectacular. Teams of this size can be quite hard work but the team worked superbly well together and did a great job. It is good to see people improving their skills and Biff completed his first mist net extractions today which can daunt some people but not this lad.
 
The total of 183 new and 46 retrap is pretty spectacular and the ces totals of 112 new and 25 retrap are also very good. MP, PA, SW, PW, AF, AM, TW

2nd July 2014 - Group Totals

 Group totals up to the end of June. 

The totals so far seem to show that it is going to be a good year for Tree Sparrow's. The benchmark for a good year is to ring over 1000 pulli so we are well on track. This is despite the fact that some large colonies we once had away from the Marlborough Downs appear to be crashing for reasons unknown while at some sites on The Downs we can't get nest boxes up fast enough.

We're so far managed to catch 2 Quail using a sound recording of a female calling with a Schedule 1 license and the team's efforts in nest recording have been well rewarded.
