Jonny and I ran a session at Somerford Common on Wednesday morning, prior to Jonny's expedition to Madagascar with his UWE colleagues. I know he is really looking forward to getting to ring some exotic species out there but wasn't disappointed in the small catch we had on Wednesday either.

The list for the morning was; Nuthatch 1; Great Tit (2); Coal Tit 1(1); Long-tailed Tit 4(3); Wren 1; Dunnock 3(1); Robin 2(1); Blackcap 1; Chiffchaff 8; Goldcrest 2; Chaffinch 1; Bullfinch 1. Totals: 25 birds ringed from 11 species; eight birds retrapped from four species, making 33 birds processed from 12 species.  The undoubted highlight was our first Blackcap of this Spring, plus another eight Chiffchaffs.  

Saturday morning saw me with Steph, Charlie and Neil at Red Lodge. The first thing to say is that, since my note to the residents about the vandalism to my feeding station and the installation of covert surveillance by the Forestry Commission, the bird table has remained unmolested for a full month now. Hopefully that is an end to that nonsense.  We only had a small catch of 20 birds this morning but, with Steph and Neil only just starting their extracting, and none of them having been available for the last couple of weeks, it was a good session to ease them back in gently to working with the birds.  The list for the morning was: Blue Tit 2; Great Tit 1(2); Long-tailed Tit 1; Wren 1(2); Robin (1); Blackcap 1; Chiffchaff 5(1); Goldcrest 1; Chaffinch 1; Goldfinch 1. Totals: 14 ringed from nine species; six retrapped from four species, making 20 birds processed from 10 species.  There were highlights: the Goldfinch is the first ever caught in Red Lodge. Since the thinning operation in 2015, this wood has begun to turn up a greater variety of birds, the star was obviously the Spotted Flycatcher last Autumn, but, as well, we have been able to add both Lesser Redpoll last December and, now, Goldfinch to the list.

Although we did not catch any in these sessions, we could map three separate Marsh Tit territorities with calling males in each of the sites.  This is pretty encouraging and, if we have a decent Spring and Summer, we might see a further welcome increase in the number of Marsh Tits in the Braydon Forest.

It is that time of the year where the winter feeding flocks of resident birds have broken up, some of the winter flocks are still around and summer migrants are on their way in. To put it another way: it can be pretty quiet.  The Firs this morning lived up to that expectation.  We had a team of four: Jonny, Ellie and Annie joined me.

There has been a lot of work done in the Firs, continuing on from the opening up of the central glade and the digging of the wildlife ponds three years ago, opening up new rides and glades, and the plan for ringing there over the summer is to start testing to see if these changes have had any impact on what is using the wood.  As (previously blogged) we caught two juvenile Spotted Flycatchers there in August last year, I will be interested to see if that was just an on passage drop in, or if there is something more exciting going on.

The list for today was; Treecreeper 1(1); Blue Tit 2(2); Great Tit 5(3); Marsh Tit (2); Wren 1(2); Robin (1); Chiffchaff 8; Chaffinch 1; Goldfinch 1.  Totals: 19 birds ringed from seven species; 11 retrapped from six species, making a total of 30 birds processed from nine species.  Highlights from the catch were: the recapture of two Marsh Tits ringed last autumn; a nice early group of Chiffchaffs and an aged Treecreeper.

The Treecreeper was one of the first ringed by me at the Firs, on the 10th March 2013. It was ringed as an adult, which means that it has survived for four years since ringing (it has not been retrapped in between times) but was at least eighteen months old at the time of ringing. Not bad for a bird with a normal lifespan of two years, but a way to go before it reaches the record of eight years and eighteen days. It still looks pretty smart to me:

Of the eight Chiffchaffs caught, four of them had what we call pollen horns:

2017 03 25CHIFFH

Jonny has a hankering to collect these and try to identify which plants the pollen comes from. If anybody happens to catch any Chiffchaffs with the aforesaid pollen horns and can separate the pollen from the bird without damaging it, Jonny would be very grateful. ST/JC/EJ/AH

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

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

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:

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

An interesting couple of sessions over which virtually the entire team took part. Thursday was at Ravensroost Woods and Saturday at the Firs.

The list for Ravensroost was: Treecreeper 1(1); Blue Tit 2(5); Great Tit 2(2); Coal Tit (6); Marsh Tit (2); Dunnock (1); Robin 2(6); Blackbird 1(1); Chaffinch 5; Goldfinch 8. Totals: 21 birds ringed from 7 species; 24 retrapped from 8 species, making 45 birds processed from 10 species.
 The list from the Firs was: Great Spotted Woodpecker 1; Nuthatch (1); Blue Tit 7(4); Great Tit 1(7); Coal Tit 1(3); Marsh Tit (2); Long-tailed Tit 1(2); Wren 2; Robin 4(2); Blackbird 1; Goldcrest 1; Chaffinch 1(1). Totals: 20 ringed from 10 species; 22 retrapped from 8 species, making 42 birds processed from 12 species. 
I never thought that when I started ringing at the Wildlife Trust's sites in autumn 2012 that the Firs would ever match Ravensroost for numbers and actually have a greater variety of species.  There has been such a strong focus on improving the habitat at the Firs, for all wildlife, that it is great to see it working. To be fair, if one of my crew hadn't let a Goldcrest escape at Ravensroost on Thursday, there would have been one more bird retrapped and one additional species processed but, as both sites have the same feeding station arrangement (peanuts, mixed seed and nyjer seed) and both feeding stations were additionally topped up the day before the ringing session, it is a valid comparison.
The highlights of the Ravensroost session were the Goldfinches and Chaffinches.  It was our best catch of Goldfinches at Ravensroost ever: not all of them were caught at the feeding station, three came to a lure in the open, on ride R38, the feeding station is part way up R28, on the opposite side of the main track.

The Chaffinches are a nice find. In 2012 and 2013 we had excellent numbers of them in the wood. However, in 2014 and 2015 the numbers fell off a cliff. 2016 was better and this is a good start to 2017, so I am hoping we will see the recovery continue. Unfortunately, at each site we caught one Chaffinch affected with the Fringilla papilloma virus. These are the first cases I have seen for a long time in the Braydon Forest.
 In the Firs, the two retrapped Long-tailed Tits were at least three years old. One of them was ringed in the Firs exactly three years ago, was subsequently recaptured twice on Somerford Common in 2015, and has now returned to the Firs.  Recapturing two Marsh Tits, which were ringed as youngsters in the Firs last year, was encouraging. There is some exchange between the Firs and Webb's Wood, but it does look as if they are breeding successfully in the Firs, as they are in Ravensroost Woods.
There was one worrying discovery:
2017 02 18greti
It looks, horribly, as if the Fringilla papilloma virus might have crossed more than the species boundary. The left leg shows fairly typical warty excrescences, the right leg has rotted away leaving a stump. There was no evidence of mite infestation, so it looks rather like a potentially bad situation.
A small anecdote to finish. One of my trainees was wildlife watching at Lower Moor Farm in the week.  Whilst enjoying great views of an Otter and a Kingfisher three photographers came into the hide. They spotted the Kingfisher, which was immediately followed by a torrent of abuse about ringers and ringing, because this particular bird happened to be one of the ten we have ringed in the last couple of years at the site.  I am afraid that I do think that what we do is worthwhile, so there is no plan to stop anytime soon.  You will always be welcome to join us for an explanation of the importance of ringing to ornithology - and I am always willing to listen to an explanation of why you think your photographs are more important than the long term studies we are undertaking. I am running a ringing demonstration at Ravensroost in April, so please come along and I will happily explain the importance of what we do. ST/JC/CS/NS/AH/SB

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
