Ringing In The Braydon Forest & Beyond

With the weather looking really dire for the rest of this week, I moved Wednesday’s projected session at Red Lodge to Saturday.  I was joined by my most experienced trainee, Jonny Cooper, for the session.  It was dull and overcast to start, with a couple of short showers of extremely fine, mist-like rain.  Not long enough or heavy enough to warrant shutting the nets but irritating nonetheless.  As the morning wore on the cloud broke and the sun came out but, unfortunately, the wind also got up – no doubt the forerunner to storm Freya – and we had to close the nets at 11:30 to avoid potential injury to the birds.

The primroses were out in full bloom: entirely appropriate for the second day of the meteorological Spring.  We didn’t have one of our larger catches: I think that this unusual weather has got the birds less interested in food and more interested in setting up breeding territories.  It was still an interesting morning though.  The catch was: Nuthatch (1); Blue Tit 7(2); Great Tit 4(7); Coal Tit 1; Marsh Tit (1); Long-tailed Tit (1); Robin 1(1); Blackbird (1); Goldcrest 3(1); Chaffinch 3.  Totals: 19 birds ringed from 6 species; 15 birds recaptured from 8 species, making a total of 34 birds processed from 10 species.

Of interest: both the Blackbird and the Long-tailed Tit were males, showing a well-developed cloacal protuberance, i.e. ready to mate already.  Blackbirds are multi-brooded and, weather-permitting, will sometimes start breeding as early as March.   Long-tailed Tits are single-brooded, and frequently start breeding in March.

This is a post by Jonny Cooper:

Friday (1^st March) saw me undertake a session at my farmland site just outside Chippenham.  This site is very open, meaning that it can be difficult to get sessions in if there is any wind. The forecast for the morning was low wind and overcast with some sunshine, perfect ringing weather for this site.

I aimed to have all the nets open as the sun was rising which meant that I arrived on site quite early to set the nets. All the nets were open by around 6:45. The first round proper delivered 12 birds; this round often catches 40-50% of the total catch at this site so I was expecting a catch of 20-30 birds. However, as the morning progressed the rounds continued to produce 10 or so birds each time leading to a total of 71 birds being processed across the morning.

The total catch was: Blackbird (3); Blue Tit 4(3); Chaffinch 9(1); Dunnock 4(1); Goldfinch 3; Great Tit 3(2); Greenfinch 11; House Sparrow 6; Linnet 1; Reed Bunting 6(1); Robin 4(1); Yellowhammer 7(1). Totals: 58 new from 11 species and 13 recaptured from 8 species, making 71 birds processed from 12 species.

There were many highlights to the catch, the single Linnet was a new bird for the site, I have often seen them around but not been lucky enough to catch them before:

6 House Sparrow was also unexpected, with only a single bird being caught before the session. There were also reasonable numbers of Chaffinch, Greenfinch, Reed Bunting and Yellowhammer; the last two being key farmland bird species that are on the UK Red List.

Overall a very pleasing session that continues to show the excellent farm management for wildlife undertaken on site.

A large part of the Wiltshire Wildlife Trust’s work is through their Education and Well-Being programme.  Christine Crookall-Fallon, the Trust’s Education and Well-being Officer, asked me if she could bring along a group of 13 and 14 year-old youths from Devizes School to our session at the Firs today.  We know the value of our ringing work to conservation but, increasingly, are made aware of the contribution it can make to the education and well-being of young people.  Given how much we get out of it,  I suppose it should be obvious.

Jonny and I arrived at 6:30 and had the nets set up by 7:30.  As we were walking down the central glade to our ringing area I looked up and was surprised, and rather delighted, to see a Brown Hare run through the clearing at the bottom of the glade. The weather was glorious, if a fair bit colder than it has been recently, but bright and, eventually, warm. Whilst processing our first round we heard a shrill triple call.  At first we persuaded ourselves it was a Song Thrush mimicking another species: Lesser Spotted Woodpecker.  After processing our second round we heard the unmistakable drumming of the real McCoy.  Cue a quick scramble for our binoculars and some good views of the Lesser Spotted Woodpecker.  It flew around the tree-tops adjacent to our ringing station before disappearing.  Unfortunately, it was immune to the lure we played for the rest of the morning.

A bit later, and before the Devizes crew arrived, a Sparrowhawk paid a brief visit to the wood, flying through at tree-top height. It landed briefly in one tree before disappearing into the distance.

Christine had a put a full programme together for her charges, so that they were on hand for any birds we caught, but were active on other things in between rounds and after we packed up for the day.  They arrived on site at 9:30, just as we were returning from a round with a good number of birds.  We processed the birds, pointing out ageing characteristics and how to sex those species (where possible).  Those that wanted to were given instruction on how to hold a bird in the ringer’s grip and then to release it safely.  By the end of the session all bar one youngster had held and released at least one bird.  One of the girls was extremely reluctant to get involved but was eventually persuaded.  After her first experience there was no further reluctance, and she coped excellently with being pecked by Blue and Great Tits thereafter and handled a good number of birds.  The highlight of the first round the students saw was a recaptured female Great Spotted Woodpecker.

The list for the morning was: Great Spotted Woodpecker (1); Nuthatch 1(2); Treecreeper 1(1): Blue Tit 10(7); Great Tit 10(10); Coal Tit (2); Wren (2); Robin 1(1); Goldcrest 1; Chaffinch 2.  Totals: 26 birds ringed from 7 species; 26 birds recaptured from 8 species, making a total of 52 birds processed from 10 species.

The last round yielded the new Treecreeper, the Goldcrest and one of the Wrens: much to the delight of the students.  People’s first experience of Goldcrest is always framed by how small they are.  When you tell them that birds of this species, weighing all of 5 grams, fly across the North Sea from Scandinavia to winter in the UK, and return across the sea in the spring to breed they find it hard to believe.

We closed the nets and took down at 11:30.

This is the sixth year that I have been carrying out my Help4Heroes sessions at Tedworth House.  As the hard work of Dave Turner and his various helpers (residents, visitors and external and corporate volunteers) has opened up the woodland and improved the habitat, so the catches have increased in both variety and number.  As usual in a woodland at this time of year, Blue Tits are far and away the largest proportion of the catch but, as ever, the site continues to offer up the odd surprise.  Today’s was a late arriving Redwing.  Nobody has seen them around the site for a couple of months and I certainly wasn’t expecting to find one in the net directly opposite my lure for Lesser Spotted Woodpecker.

Why a lure for Lesser Spotted Woodpecker? The site is perfect for them although, unfortunately, their numbers have dwindled nationally.  My Braydon Forest sites are a known haunt for them, with them being seen annually and confirmed breeding quite regularly. One of the staff had reported a sparrow-sized woodpecker in one of the trees close to the House.  He was shown some pictures of woodpecker type birds: Nuthatch; Green Wood pecker and Great Spotted Woodpecker and, finally, Lesser Spotted Woodpecker and he was definite that was what he saw.  Fortunately, Jack Daw who, besides being a first class bird ringer, is the maintenance man at Tedworth House, has also seen the bird since.  Unfortunately, it didn’t show this morning.

Jack was a star this morning, standing in for Dave Turner, who was not on site today. He helped me get the nets up and open and, more importantly, provided the essential bacon sandwich.  For someone who has ringed as many thousands of birds from as many species as Jack has, he had never ringed a Nuthatch. So, when we caught a female Nuthatch in the first round, I insisted he break his duck and ring a Nuthatch, by way of a thank you.

The catch was certainly interesting: Nuthatch 2; Blue Tit 16(13); Great Tit 1(3); Coal Tit 2; Dunnock (2); Robin 2(1); Redwing 1; Song Thrush 1; Blackbird 1; Chaffinch 5; Goldfinch 1.  Totals: 32 birds ringed from 10 species; 19 birds recaptured from 4 species, making 51 birds processed from 11 species.  This is our largest catch at this site. The previous best was 49 birds processed from 10 species in September 2017. Most of those birds were juveniles from that year’s breeding effort, before they have had time to succumb to predation, illness and starvation, so having such a good catch at the back end of the winter is highly encouraging.

One slightly odd feature: all 5 Chaffinch caught were female.  Fortunately, no sign of any FPV or mite infections.

I was joined for about 15 minutes by a small family group (mum, daughter and son) and all three got a lesson in how to safely hold and release Blue Tits and what it is like to be bitten by them (“not as bad as chickens” was the consensus opinion).

On the basis that, having not had Brambling in our local woods before, I wanted as many of our team to get the chance to see them as possible, I scheduled today’s session back at Somerford Common, so that Steph and Lillie would get the opportunity.  Lillie is on half-term holiday this week, and Steph took the morning off work, so they could come along.  While topping up the feeders on Monday there was a good flock of 30+ Brambling in the area, so I knew there would be a chance of catching another one or two.

Jonny and I met at 6:15 and had the nets open by 7:00, by which time it was already daylight, so it looks like we are going to be starting much earlier for the next few weeks, until the brief respite of the clocks going forward.

Since Monday, the seed feeders had been emptied, the peanut feeders were half empty and the nyjer seed feeder was one third empty, so I was reasonably confident of getting a decent catch.  In the event it was not as big as I hoped, but it was a nice, varied collection of birds.

Steph ringed her first Brambling and Siskin; Lillie ringed her first Brambling and Lesser Redpoll.  One thing we have noticed is the increase in our catch of Chaffinch this year.  We have already caught and ringed 35 in the first 6 weeks of 2019.  If it keeps up at this rate we will eclipse any previous catches for this species.  On the down side, we are catching several more, at least one per session, that we cannot ring, due to growths on their legs.  None have looked as though they are mite infestations: they do look like Fringilla Papilloma Virus infections.

The catch for the session was: Nuthatch (1); Treecreeper 1; Blue Tit 7(2); Great Tit 6(3); Coal Tit (1); Marsh Tit (2); Robin (2); Goldcrest 1; Chaffinch 6; Brambling 2; Goldfinch 5(1); Lesser Redpoll 3(1); Siskin 1.  Totals: 32 birds ringed from 9 species and 13 birds retrapped from 8 species, making 45 birds processed from 13 species.

One of the most difficult birds to catch when using standard ringing techniques is the Skylark, Alauda arvensis.  There are a lot of reasons for this: they inhabit the centre of fields; they fly up vertically to sing; they drop more or less straight down and then run along through the vegetation to their nest, there really is little opportunity to catch them.

The group has only caught a total of 22 since it came into existence, and none since the end of 2012.

Jonny decided to try out a technique that we have been discussing for a while: drag netting.  He co-opted a couple of helpers to handle the net and he followed behind to control the operation and to handle anything that they managed to catch in the net.

It worked:

Not just once, but twice!  It is turning into a very interesting February.

Jonny, Annie and I went to Ravensroost Woods this morning for a session. First thing we found was that someone has stolen one of my peanut feeders. What sort of person steals a cheap peanut feeder from a nature reserve? With the squirrels doing their best to destroy the seed feeders and thieves stealing other feeders, keeping the feeding station going is a bit like hard work at times.  It is there to help with the birds’ survival over the winter.  February and March is the empty time of the year when birds are at their most vulnerable.  I feed weekly between November and the end of March in a number of Braydon Forest sites.  Yes, it makes the ringing easier, but that is secondary.

We set the nets along the ride with the remaining feeders and, as an afterthought, we set another couple of nets along the edge of the main path, opposite a newly coppiced coupe. We have frequently seen birds flying across the path but have never got around to putting up any nets along there. Jonny suggested we put on a lure for Brambling just in case. I have been birding there since 1998, ringing there since 2009, and I have never seen or heard Brambling there but, if you don’t try! 

Anyway, I extracted and ringed only my second ever Brambling: two in the same week.  We have only caught 8 Siskin in Ravensroost since 2009 and none since March 2014 – so the 2 females caught were a surprise and very welcome.

It just goes to show, some days can start out bad but end up being pretty good. In all we caught 95 birds in just 7 nets: Nuthatch (2); Blue Tit 29(13); Great Tit 15(12); Coal Tit (5); Marsh Tit (1); Long-tailed Tit (1); Robin 1(1); Chaffinch 9(1); Brambling 1; Lesser Redpoll 2; Siskin 2.  Totals: 59 birds ringed from 6 species; 36 birds recaptured from 8 species, making 95 birds processed from 12 species.

After Monday’s excellent session at Somerford Common, there was a lot of mid-week activity from the group members.

Jonny spent Tuesday morning ringing one of his farmland sites close to Chippenham.  His list for the day was: Blue Tit 2(3); Great Tit 4(3); Wren (1); Dunnock 2(1); Robin (1); Blackbird 3; Chaffinch 7; Greenfinch 1; House Sparrow 1; Reed Bunting 2; Yellowhammer 3.  Totals: 25 birds ringed from 9 species; 9 birds recaptured from 5 species, making 34 birds processed from 11 species.

On Wednesday Jonny, Ellie, Emmeline and myself carried out a session adjacent to the education centre at Lower Moor Farm.  Unfortunately, it was a very small catch for such a big team.  I am not sure why it was so quiet, we usually have excellent catches in this area but a mere 13 birds was really not what we were looking for: Blue Tit 2(4); Great Tit (1); Long-tailed Tit (1); Wren 1; Dunnock (1); Robin 2; Bullfinch 1.  Totals: 6 birds ringed from 4 species; 7 birds recaptured from 4 species, making 13 birds processed from 7 species.  The Bullfinch was a stunning male.  We did catch a female but she had bad legs (Fringilla Papilloma Virus) and had to be released without being ringed.

Andrew had a similarly frustrating session at Lacock Allotments on Friday.  Having been away in Iceland for a week doing his wildlife tour guide activity, he arrived at the allotments to find empty bird feeders. He topped them up and set the one net adjacent to the feeding station but the birds did not respond in any number.  His list for the session was: Blue Tit 1(3); Great Tit 3(2); Coal Tit (1); Robin 1;  Blackbird 2. Totals: 7 birds ringed from 4 species; 6 birds recaptured from 3 species, making 13 birds processed from 5 species.

Jonny, clearly being the biggest glutton for punishment, went to his other farmland site near Langley Burrell, Chippenham on Thursday.  There is a stream that runs through the site, with a narrow foot bridge across it.  Putting nets on bridges across streams is a good way of catching Kingfisher, as they bomb up and down the waterway, as Jonny found out by doing just that.

This is clearly a good site: Kingfisher (1); Blue Tit (8); Great Tit 6(3); Long-tailed Tit (1); Dunnock (1); Robin 1(1); Chaffinch 1(1); Goldfinch 5; Greenfinch 1.  Totals: 14 birds ringed from 5 species; 16 birds recaptured from 7 species, making 40 birds processed from 9 species.

Having missed out on Webb’s Wood on Sunday, as the rain kindly waited until I had finished setting my nets before falling, leaving Steph and Lillie with a wasted journey from Cirencester, and me with a car full of wet nets,  I decided to go back and run the session on Friday.  The list from the session was: Nuthatch (1); Treecreeper 1; Blue Tit 6(7); Great Tit 6(8); Coal Tit 2(3); Marsh Tit (1); Robin (1); Goldcrest 1(2); Chaffinch 2.  Totals: 18 birds ringed from 6 species; 23 birds recaptured from 7 species, making 41 birds processed from 9 species.

The highlight of this catch was the recaptured Marsh Tit.  It was ringed as an adult on the 13th February 2013: making this bird at least 7 years old against a typical lifespan of 2 years. Mind, the record is over 11 years for this species.

In summary, we carried out 5 ringing sessions in 4 days, processing 131 birds from 20 species.

 

On Sunday I planned a session at Webb’s Wood. The forecast was for the rain to stop at 7:00 and for it to stay dry until midday.  I thought I would have a bit of lie-in and go for a 7:30 start.  I had the nets up and open by 8:15. At approximately 8:16 it started to rain: not heavy but persistent drizzle, so I took down again.  Very annoying: a solitary Blackbird, who blundered into a closed net, got a nice new ring.  That was disappointing. However, I had arranged with Jonny Cooper that we would be having another session at Somerford Common on Monday.

Having set up a feeding station at this part of the site two weeks ago, and carrying out the previously blogged about test session last week, Jonny suggested some slight changes to the net rides, and they paid dividends.

The southern end of Somerford Common always used to be my go to place for Lesser Redpoll, not that we ever caught that many but it was regular, with 10 being the largest catch. For a number of perfectly valid reasons (improving the habitat for Marsh Fritillary being a key one), the Forestry Commission carried out some significant clearing work which reduced its attractiveness to birds, so catching 3 Lesser Redpoll and a Siskin last week was encouraging. Catching 14 Lesser Redpoll and another 2 Siskin this morning is evidence that this site has recovered significantly.

However, the real highlight was unexpected, if not tried for. We had heard a few Brambling around the area but these birds have never been caught and ringed in any part of the Braydon Forest. There is no reason why not: most of the Forest is beech wood and they are regularly caught in the woods to the east of Swindon and in Savernake Forest and the surrounding woodlands but they just never seemed to get to the woods west of Swindon. I had spread some seed on the floor for Chaffinch and put on a lure for Brambling just in case. It worked: a male and a female dropped in and were caught and ringed.

In addition, we caught another Great Spotted Woodpecker, 3 new Nuthatch, and another new Marsh Tit at the site and recaptured the Marsh Tit ringed last week.  Amongst all of the other birds caught, we did recapture a Blue Tit that was ringed as a juvenile in October 2017, and has been recaptured on several occasions, most recently in April of last year. On each of those occasions we noticed nothing out of the ordinary. This time it was sporting a huge avian pox pustule. Its weight was fine and it was feisty enough. We gave the weighing pot a thorough clean out with alcohol rub after weighing it: We don’t want to be culpable in spreading the infection.

The list for the day was: Great Spotted Woodpecker 1; Nuthatch 3; Blue Tit 16(7); Great Tit 4(8); Coal Tit 3(1); Marsh Tit 1(1); Robin 1; Chaffinch 6(1); Brambling 2; Goldfinch 4(1); Lesser Redpoll 14; Siskin 2. Totals: 57 birds ringed from 12 species; 19 birds recaptured from 6 species, making a total of 76 birds processed from 12 species.

On returning home, looking out the kitchen window, I couldn’t understand why there were no birds on the feeders and then I saw this fellow sat on the garden fence:

I couldn’t get close enough to get a better photo but you can see what it is.

After Thursday’s and Friday’s snowfall, I decided not to go ringing last weekend, as I felt the birds had enough to deal with, finding food and staying warm.  I set up a new feeding station in the old paddock area at Somerford Common before the snows fell last Thursday.  This large area is now going to be run on a coppicing regime by the Forestry Commission.  Most of the bushes have been cleared, plus a huge number of trees.  What is left is a sparse landscape with odd min-copses of either conifers or silver birch.  This area was always our best spot for Lesser Redpoll, so I selected the nearest mini-copse of silver birch to where we used to set our nets and put up a few feeders and cleared the regrowth around the edge for nets.

I went out on Tuesday to fill the feeders on my sites and was pleased to see a couple of Siskin at the Somerford Common feeding station.  This morning I was joined by Jonny and Andrew and we surrounded the copse with nets, hoping to catch the birds coming into or leaving the feeders.  There were small groups of Lesser Redpoll and Siskin and, we are pretty confident, Brambling in the area.  It was an experiment. It worked to a degree, but we did find that the Siskin and Redpoll were coming in through the treetops, dropping down and then leaving near to vertically from the feeders.  Not having canopy nets we are going to have to find a better solution.  At Webb’s Wood, which is my usual Siskin catching haunt, we have the nyjer seed feeder set in a narrow ride, with a net immediately adjacent to it.  We will cut something similar at Somerford and, hopefully, have two Siskin catching stations.  The degree to which our experiment worked was 3 Lesser Redpoll and 1 Siskin.  We caught no Siskin at all last year and only 2 Lesser Redpoll, so this was a thoroughly pleasing catch. This male Redpoll was the first one caught: an absolutely stunning bird.

The Siskin was a juvenile female:

The list for the session was: Great Spotted Woodpecker 1; Blue Tit 5(4); Great Tit 7(3);  Coal Tit 2; Marsh Tit 1; Robin 1; Chaffinch 5; Goldfinch 1; Lesser Redpoll 3; Siskin 1.  Totals: 27 birds ringed from 10 species; 7 birds recaptured from 2 species, making 34 birds processed from 10 species.

Catching our second new Marsh Tit of the year was also a bit of a bonus: especially given that the habitat was completely wrong for this species.   The catch died off at 10:30, so we packed up at 11:00, leaving the birds to feed in peace.
