West Wilts Group
Various: Monday 13th, Wednesday 15th and Thursday 16th March 2017
It has been a bit of a busy week with three sessions. Monday's session was to replace the scheduled meeting at Ravensroost Woods on Sunday. Fortunately Ellie could join me for this session and we had a reasonable catch of 37 birds. The list for the day was: Great Spotted Woodpecker 1(1); Nuthatch 1(1); Blue Tit 3(4); Great Tit 11(2); Coal Tit 1; Long-tailed Tit 1; Wren 1(1); Dunnock (2); Robin (1); Goldcrest (1); Chaffinch 1; Goldfinch 4. Totals: 24 ringed from 9 species; 13 retrapped from 8 species, making 37 birds processed from 12 species.
Wednesday was my monthly Help4Heroes session at Tedworth House. I started late, arriving at 7:00, to find that none of the feeders had been topped up, so I was expecting one of the lighter sessions. Fortunately, I had some feed in the car and topping up the feeders helped improve the catch somewhat. The day turned into a bit of a stunner. Many thanks to Jack Daw for all his help setting up the nets. Okay, I only caught 28 birds but it was an excellent session for three very good reasons: I had a lovely little ringing session with a group of recovering soldiers. It is fascinating to see how they respond to being in close proximity to a tiny bird. Two of them got to hold and release the last two birds of the session. It is interesting to see how they respond when asked if they would like to hold and release a bird. It is like the old jokes on volunteering: watching the majority step back to leave those who are slower to react. The two other reasons were both to be had on my second round of the day. First, I caught my fourth Mistle Thrush on the site, the third to be ringed there. Given how few are caught and ringed each year, this is a remarkably productive site for them. As you may remember from last month's report, there has been an over-wintering Black Redstart at Tedworth House. It has been feeding up on hibernating ladybirds. Approaching the net by the vegetable / herb garden I saw what I initially took to be a Robin in the net but, as I got closer, I saw a distinctive red tail. There is only one over-wintering red-tailed bird in the UK: the Black Redstart. Apologies for the terrible photographs but my camera decided to throw a wobbler and I had to take them on my mobile, which was just about out of charge and couldn't fire the flash. News of the Black Redstart drew quite a crowd coming to see this uncommon bird.
As far as I have managed to find out, this is the fifth one of the species ringed in Wiltshire and the first since 2008. The list for the day was: Nuthatch 1(1); Blue Tit 6(4); Great Tit 2(2); Coal Tit 1(2); Wren 1; Dunnock 1(2); Robin 1; Black Redstart 1; Mistle Thrush 1; Blackbird (1); Chaffinch 1. Totals: 16 ringed from 10 species; 12 retrapped from 6 species, making 28 birds processed from 11 species.
Thursday was a special session, arranged with Rachel Bush from the Wiltshire Wildlife Trust, to work with the Youth Well-Being group. It was a late start with the net set for a 9:30 start. We only caught ten birds but the youngsters had a cracking time with what we caught, From initial consternation and some disgust, they soon got into the session, with lots of sensible questions and enthusiasm for being taught the ageing and sexing of the birds caught. All of the birds were, unusually, new catches. They were: Blue Tit 2; Great Tit 3; Dunnock 1; Chiffchaff 1; Chaffinch 1; Goldfinch 1; Reed Bunting 1. Total 10 birds processed from eight species. To top it all off, I had a gang of willing helpers for the take down, which meant we were done in half the time. After the last time I did one of these sessions I got a new trainee out of it - and I have had an enquiry this time as well. ST/EJ/JD
Webb's Wood: Saturday, 4th March 2017
A lovely session in Webb's Wood this morning. With two of my more inexperienced trainees in attendance (Annie has only just started extracting; David has just had a couple of taster sessions, and I started him ringing birds today) I only set three nets (2 x 18m + 1 x 12m) around the feeding station and we were rewarded by a catch of 40 birds from 13 species. The catch came in regular intervals, giving plenty of time for me to spend with David, helping him to develop the techniques he will need in his ringing career.
We caught four Great Spotted Woodpeckers: equalling the largest catch of this species that I have had in one session. One of the woodpeckers we were unable to sex. Although the nape was black, there was a smattering of glossy red feathers throughout the nape area. The texts acknowledge the existence of the situation but focus on what it means for ageing the bird (nothing, as the texts have it) and say nothing about the sex of the bird. Unfortunately, we didn't manage to catch the Lesser Spotted Woodpecker that sat and called for about 10 minutes in the trees just behind our ringing station. The list for the day was: Great Spotted Woodpecker 4; Nuthatch 2(1); Blue Tit 5(1); Great Tit 4; Coal Tit (4); Marsh Tit (2); Long-tailed Tit 1(1); Robin (1); Blackbird 1; Goldcrest 1; Chaffinch 4; Lesser Redpoll 3; Siskin 5. Totals: 30 birds ringed from 10 species and 10 birds retrapped from six species.
We caught another four Chaffinch but, unfortunately, a fifth had to be released without ringing, as it was suffering with the Fringilla papilloma virus. ST/AH/DW
Somerford Common: Saturday, 25th February 2017
A second session in a Forestry Commission wood in the Braydon Forest where I have recently had to move the feeding station, produced another good and varied catch. Unlike Red Lodge, I had to move the feeding station because the path on which it was previously set is now impassable: a combination of wet weather and horses has churned it into a real swamp. Also unlike Red Lodge, there have been no subsequent vandalism problems.
I was joined for this session by Jonny, Steph and her daughter Lillie. Lillie is a delight and, at a mere seven years of age, is knowledgeable of the birds we process and is very confident in her handling of them (well, all except the Great Spotted Woodpecker, anyway). Definitely a ringer of the future. However, her major contribution to the day was her discovery that the rulers we use for measuring the wings (which have a small rectangular stop at the 0 point of the rule) could be made to walk across our ringing table if placed on the end stop. We have a new game for quiet sessions.
The wood offered decent shelter from what wind there was, the weather was dull and overcast for most of the session, almost perfect bird ringing conditions. We set three net rides, anitcipating that most of the action would be around the feeding station. 72 metres down the main track and 12 metres behind the bird feeders, to catch anything coming through the wood to visit the station. The list of birds caught was: Great Spotted Woodpecker 1(1); Nuthatch (1); Treecreeper 1; Blue Tit 8(6); Great Tit 3(4); Coal Tit 10(6); Marsh Tit (2); Long-tailed Tit (8); Dunnock (2); Robin 4; Blackbird (1); Chaffinch 3; Goldfinch 1; Siskin 2; Lesser Redpoll 1. Totals: 34 birds ringed from 10 species; 31 birds retrapped from nine species, making 65 birds processed from 15 species.
There were a number of interesting things arising from the catch. It is known that Long-tailed Tits hang around in family groups. We caught numbers JJP468 to JJP473 inclusive. All were ringed on the 24th August last year at Somerford Common. We also caught consecutively numbered adult male and female Great Tits, originally ringed in December last year, adjacent to each other in the same net. I had the same occurrence at Red Lodge yesterday, where both were originally ringed in March of last year, and I have seen it before in Ravensroost. I have searched the literature and, although male Great Tits are said to be usually monogamous within the breeding season, there is nothing about the maintenance of the pair bond outside the breeding season. Looks as though there might be a study and a paper in this. Of course, this is the sort of thing that can only be investigated through the ringing scheme, as it is the only permanent way of identifiying individuals.
We ringed our second (and third) Siskin for the site, a male and a female (the first was back in November 2013), plus our second Goldfinch for the site (the first was in November 2015), our sixth Great Spotted Woodpecker of the year, and a Treecreeper that, for once, looked comfortable when photographed (too often they adopt a hunched posture that just doesn't look right). A few photographs from today's session follow:
Red Lodge Plantation: Friday, 24th February 2017
I have been having a bit of an issue at Red Lodge recently. Because the main track has been severely damaged by the machinery used for the thinning operations over the last year-and-a-half, I can no longer get my car the kilometre into the wood where my feeding station is set. It is a long trek to get all the equipment and the ringing station in place for a session, so a few weeks ago I moved the feeding station to a position just a couple of hundred metres away from where we park the cars. The feeding station had been in place for 5 years with no problems of theft or vandalism. The new position has clearly upset somebody: 3 days after the bird table was dug into its new position I found it had been uprooted and put to one side. Thinking it might have just been blown over in this interminable bad weather, I dug it back in a few metres back from where it was before. The next week, when I went to top up the feeders, no bird table. I eventually located it in the middle of a nearby pond. On the basis that I don't give in to bullies, I dug it back in, with the pole considerably deeper into the subsoil.
Anyway, I was planning a session for this morning and went to top up the feeders yesterday and, presumably because you have to be pretty daft to go walking in the woods when it is blowing up to 60mph (trees are down in the wood), the table was still in place. So, this morning I set my nets and, as I was finishing setting the last net, adjacent to the bird table, a 50-something male, clad in something that looked remarkably like a dry suit, came haring through the woods on his mountain bike, on a collision course for my nets and the table. I stopped him, pointed out where my nets were and the work that goes on and why I supplementary feed in the wood. I raised the problems of mindless petty vandalism on Forestry Commission sites. I dropped into the conversation that the FC have said they will put up covert camera coverage and alert the police if it happens again. He protested mightily that he would never have done anything like that. Funnily enough, I got the feeling that the problem might have been resolved.
As this was a solo session, I only set two 18m and one 9m nets. It still ended up being a lot of work, with large numbers of Blue, Great and Coal Tits turning up. Anybody who has been ringing for any length of time will know of the "fun" of extracting large numbers of Blue Tits, particularly when on your own, and when a sizeable proportion decide to double pocket or spin, or combine them together. Having moaned a bit, it was actually an excellent session. The highlight had to be the first Siskin caught in the wood since I started ringing there in autumn 2012. This follows hard on the heels of the first Lesser Redpoll caught in the wood in December 2016. Perhaps one of the impacts of the thinning of the woodland is to have made it more attractive to winter finches.
As well as the Siskin, I was lucky enough to catch a couple of Great Spotted Woodpeckers, which makes five for the year so far: we caught only nine in the whole of 2016. We have only caught one previously in Red Lodge, in 2015. There was a cracking male Nuthatch. Sexing Nuthatches is very easy: the male has dark brick red edges to its undertail coverts and also on the body wall adjacent to the axillaries; the female has paler, buff fringing.
The list for the day was: Great Spotted Woodpecker 2; Nuthatch 1; Blue Tit 18(11); Great Tit 9(10); Coal Tit 8(3); Marsh Tit (1); Long-tailed Tit (1); Wren 1(1); Robin 1(1); Blackbird 1; Goldcrest 1; Chaffinch 1; Siskin 1. Totals: 44 birds ringed from 11 species; 28 retrapped from seven species, making 72 birds processed from 13 species.
Several of the Great Tits were being fed on by ticks, which I removed with my needle forceps. It is astonishing how the birds do not struggle when you are doing this - almost as if they know you are doing something to benefit them. ST
Ravensroost Wood & The Firs: Thursday, 16th & Saturday, 18th February 2017
An interesting couple of sessions over which virtually the entire team took part. Thursday was at Ravensroost Woods and Saturday at the Firs.
Tedworth House: Wednesday, 15th February 2017
It was a grey day today, which eventually turned to rain at midday, leading to Dave Turner, (Wildlife Trust Special Projects Officer, provider of sausage sarnies and all round good bloke and my help at Tedworth House) and myself getting soaked whilst putting the equipment away. Fortunately, I am out again tomorrow and it is scheduled to be dry and a bit sunny, so I should be able to dry them off. Whilst walking down to set up a couple of nets adjacent to the herb and vegetable garden by the house, we were treated to excellent views of the Black Redstart that has made the House his home this winter. Talking to Chas, the groundsman at the House, it has apparently found a cache of over-wintering ladybirds which it flies up and picks off to eat. It is now accompanied by a Robin, that has taken to picking up any that are dislodged by its feeding activities. I have not attempted to target the bird to ring it.
We had a good session, with the largest catch taken at the site. It was mainly Blue Tits, but there were some nice surprises in there as well. The biggest surprise was a Great Tit. I didn't recognise the ring number, TT96119. I subsequently learned from Jack Daw that he ringed the bird in the nest on 12th June 2016, in the area of Barrow Plantation just off A338 at CC tank crossing,` around 2 miles or so north of the site at Tedworth House. It was one of a brood of eight. Blue and Great Tits are known to disperse widely away from their natal sites. I see regular movements into and around the Braydon Forest but it is not usually through such an urban area.
The list for the morning was: Great Spotted Woodpecker 1; Treecreeper (1); Blue Tit 12(5); Great Tit 7(2); Coal Tit 4; Dunnock 2; Robin (1); Song Thrush 1; Blackbird (1); Goldcrest 2; Chaffinch 1. Totals: 30 birds ringed from 8 species; 10 birds retrapped from 5 species, making 40 birds processed from 11 species. ST
West Wilts Group: non-group activities 2016
The West Wilts Ringing Group is actively involved in a large number of local projects: constant effort sites at Cowleaze Wood and Lower Moor Farm; the Braydon Forest Living Landscapes and Marsh Tit projects and the Ravensroost coppice project are all long-term projects focused entirely on our activities in Wiltshire. On top of that, we probably have one of the heaviest schedules of organised ringing demonstrations and social engagement programmes of any ringing group in the country.
Outside of that, however, we are also pretty active on other projects with other organisations. Ian Grier and Andy Palmer are long-term collaborators with the RSPB on the Wessex Stone Curlew project. Ian has been training RSPB staff (and Andy) on how to ring Stone Curlew chicks for three years now. In the 2016 summer season, as well as the Stone Curlew ringed by the RSPB staff, Andy ringed a further 10 chicks.
Jonny Cooper has been very busy this year. The year started with him working with the Widlfowl and Wetlands Trust to ring and radio track a wide variety of birds using the Newport Wetlands. I also got involved in this project and we had a great time ringing a number of bird species that we would not normally have expected to get close to. Further to that, Jonny spent time with the WWT at Slimbridge, Martin Mere, Caerlaverock and on Lake Windermere, doing a wide range of ringing and getting experience with a number of different catching techniques, including cannon netting and whoosh netting. In addition, it would be wrong not to mention his trip to Iceland and his long weekend at Spurn Point, immediately prior to my elevating him to his C-permit.
Although, unusually, I didn't get out with the Wash Wader Group or the North Thames Gull Group in 2016, Jonny and I have already started 2017 with a trip to Pitsea with the NTGG, and we have another two sessions lined up with them this Spring. So our additional birds for 2016 were as follows:
West Wilts Ringing Group Totals 2016
A quieter year than last year for various reasons but, it would seem, a poor breeding season for many of our commoner birds. For example, Blue Tit ringed was down by 103 birds on last year: an 18% reduction. That reduction was almost entirely down to there being fewer young fledged this year. The ratio of adult to young in every other year recorded has been 40:60. This year the proportions were reversed.
Despite it being a quieter year there were quite a few highlights. Without doubt, the star bird was the Yellow-browed Warbler, only the second caught in Wiltshire. The previous one being caught in 2005. There were hundreds of them all around the coast but very few came inland, and there were very few sightings in Wiltshire. Also, Spotted Flycatcher were caught for the first time in the Braydon Forest: two in the Firs and one in Red Lodge in the autumn. All three birds were juveniles and, given that at least one brood was rescued and reared at the Oak & Furrows Wildlife Centre at Blakehill Farm, we can be pretty confident that they are breeding in the area. Almost as exciting was catching two juvenile Lesser Redpoll at the meadow pond in the Ravensroost complex. These were newly fledged birds, indicating that they, also, might well be breeding within the Forest.
We had a good year for Kingfisher at Lower Moor, with five juveniles ringed and three other individuals recaptured, including the first one we ringed at Lower Moor, in August 2014 and a bird that was originally ringed at Waterhay and dispersed westwards to end up at Lower Moor.

Group highlights have included both Andrew Bray and Jonny Cooper being awarded their C-permits. During the year the group carried out a number of ringing demonstrations, notably for the Wildlife Trusts' Trainees Residential Course at Langford Lakes in January (trainees from Wiltshire, Somerset, Devon and Dorset); the Help4Heroes Families' Day and the Nationwide Building Society Families's Day, both in March, the Wiltshire Wildlife Trust's Watch Group in November plus nine sessions at Tedworth House and our usual sessions at Ravensroost Woods and Ravensroost Meadows. I also became involved in the work of the Wildlife Trust's Well Being Team. You can read about what the Well Being Team does on the Wildlife Trust's web-site: it is a very worthwhile social enterprise, for which the Trust should be applauded. We know that the people who have attended the talks and demonstrations have thoroughly enjoyed them (and I have recruited a ringing trainee from one of the events). Mike and Rob have already kicked off 2017 by running the demonstration for the Wildlife Trusts' Trainees at Langford Lakes again this January, which has generated another youngster interested in becoming a ringer. We look forward to an exciting and interesting 2017 (when it stops raining). ST and the rest of the WWRG
