Another way of making entrances in situ

We have reported on projects that make entrances in situ, by using a former which is removed when the mortar is set (see here and here). Unless one makes many formers, one has to spend many hours waiting for the mortar to set.

This is another way of doing it by making a simple plastic insert out of a piece of 50mm OD uPVC pipe that stays in the wall. It is a lot easier to make these inserts than making formers.

As an experiment, I bought 2 metres of grey pipe from Homebase for £3.99 (see here). This pipe has an internal diameter of 46.5mm, which both Starlings and Swifts can get into. If such a pipe is squashed then it should exclude Starlings but still admit Swifts.

The pipe is cut into 40mm pieces, placed in an oven at 120°C for 10 minutes, then pressed into a D-shape using a flat piece of wood with another piece attached to it to control the height.

With a flat piece of wood 44mm wide by 29mm high, the width of the entrance piece is 57mm
With 30mm wide by 31mm high, the width is 56mm.

Starlings should not be able to enter either of these entrances, but the 31mm high one may be easier for Swifts.

Finally to give the Swifts some grip, the floor is scored with a soldering iron to make a toe-hold.

Disclaimer - this idea has not yet been tried on a project, but it is so simple and cheap that anyone could do it. Further work is needed to establish the optimum height that will exclude Starlings.

A Swift weather vane from Andy Jarrett

Those who visited our stand at Birdfair 2016 will have noticed the new Swifts Local Network logo. This was derived from a picture of a new, commercially available, Swift weather vane made by Andy Jarrett

Ever since I installed a Swift weather vane on my house in 2012 (see story), people have got in touch to ask where they can get one. 

Mine is a one off, commissioned by a friend as a birthday present, so, until now, I could not help them.

We are happy to feature here this rather nice picture of Andy's new weather vane on Richard Porter's house in Cley.

The Manthorpe Swift Brick back story

The Manthorpe Swift Brick has been announced and is now in full production. It is well described on Manthorpe's website, so we thought it worth describing how it came about.

The origins of the concept go back to 2014 when Judith Wakelam wished to add more nesting places on the gable end of her bungalow after having success with an external nest box. Bill Murrells came up with the idea of making a Swift entrance piece to replace a half brick in the wall. 3 such entrances were installed, and since then Swifts have bred in one of them and have explored the other 2.

Bill's entrance pieces were fabricated out of pieces of clay air brick liner; we have implemented one other project using this idea. Since then we have found it simpler to cast the entrance pieces using a simple mould.  A further 7 projects have been completed using cast entrance pieces, mostly half-brick sized and one with a whole brick sized entrance.

Extensions of the idea by casting entrances in situ have also been completed, one such project in Spain resulting in 100 nest places in a castle.

There are case studies of all these projects here

In all cases, the final result is attractive and neat, giving secure accommodation for Swifts. The approach has been labelled "The Cambridge System". [We hope that the Cambridge System itself will be commercialised soon].

At this point, on a visit to Cambridge by John Day of the RSPB he thought that the concept might be of interest to Barratt Homes. RSPB and Barratt have a partnership agreement. In October 2015, a meeting was arranged with Technical and Design Director Michael Finn. Michael carefully assessed what we showed him, and commented that when they put accessories, such as ventilation grills, in walls they use injection moulded products and he asked whether it would be possible to have an injection moulded Swift box.

It so happens that, in 2013, we had looked at the potential of an injection moulded Swift box so we produced a computer model of what we thought would be a simple, cheap and unobtrusive injection moulded Swift box.

I dug this out and sent it off where it ended up with the design engineers at Manthorpe Building Products, who immediately understood what was required and produced a first design, including their own innovative ideas.

On a visit to Manthorpe's offices in early December 2015, Paul Stephen, RSPB, and I were shown a complete 3D-printed prototype. The level of thought put into the detail was impressive.

A few iterations later and the product has now been launched and the first examples have already been installed.

Injection moulds are expensive, but the per unit costs are low. So it took a fair bit of courage to commit to an untried and untested design. There would have been no other way of exploring this approach.

This project would not have happened without the partnership between Barratt Homes and RSPB. You can read the RSPB press release.

We look forward to hearing about the first occupants of these revolutionary new Swift boxes.

Birdfair 2016

After the success of Birdfair 2015, we just had to do it again. For the second time, Swift Conservation, Swifts Local Network and Action for Swifts got together to showcase Swifts, their challenges and opportunities.

Edward Mayer of Swift Conservation gave a well-received talk at the Anglian Water Birdwatching Centre (AWBC) encouraging everyone to put up some Swift nest boxes.

On our stand, with plenty of help from SLN members, we got to talk to a large number of people including important celebrities, Chris Packham, Nick Baker, Richard Porter and Mike Clarke, RSPB CEO.

We had 3 TV monitors showing rolling videos, and an attraction call system drew people into the stand. 5 swifts flying in a mobile above the front of the stand made us easy to find. 

This all impressed the judges to the extent that we were awarded Second in the Best Stand Awards 2016, conservation category.

We had a first production example of the new Manthorpe Swift Conservation Brick, which was universally acclaimed as a game changer: It is mass produced, so is a low price, very easy to install, conforms to all building standards and is unobtrusive. It should gain wide acceptance by builders and architects. Chris Packham quickly got it, saying "this is the way to go".

We recovered our costs by selling John Stimpson Model 30 Swift boxes, attraction call systems, mobiles, badges and nest concaves, but more importantly we think we persuaded a lot of people to do something to help Swifts.

We will surely be back next year.

There are a few pictures below and many more pictures by Judith Wakelam here

Edgecombe Flats

In 2010, Cambridge City Council, helped by AfS,  installed 71 nest boxes on their properties at Edgecombe flats. In that first year, one of the residents, Peter Glass, played attraction calls from his balcony, resulting in 2 occupied boxes in 2010. Since then, 2 or 3 of the 4 boxes above the front of Peter's flat have been occupied by Swifts, but, as far as we know, none in the other 67 boxes on the site, until this year, 2016.

We have not said much about Edgecombe flats in previous years, because progress has been slow. The 71 boxes include 50 Zeist boxes made by John Stimpson, 5 boxes made out of water pipes and four 4-box cabinets.

Peter Glass's flat, 2016
Having established occupancy in Peter Glass's boxes, in 2013 we installed a solar panel driven attraction call system with a tweeter in one of the 4-box cabinets, but this did not give a result.

The boxes above Peter Glass's flat were the only ones with major exposure to the sun, so they were given a double roof, painted white. This was an early prototype of the Model 30 now also made by John Stimpson.

In early 2016 we gave 2 of the boxes on the other side of the building a white roof, in the hope that the Swifts might recognise them. These boxes were also the closest boxes to the attraction system.

The result was that these 2 boxes were occupied, whether because of the white roofs or proximity of the attraction calls we cannot say.

In July, Chris De Ruyck of the RSPB was looking for suitable places to study Swift nest boxing projects, and so he spent some time at Edgecombe flats, resulting in him finding a total of 12 boxes occupied by Swifts, and many more with evidence of House Sparrows.

Some of the boxes occupied by Swifts also show evidence of previous occupancy by the sparrows, showing that Swifts are quite capable of nesting on top of a House Sparrow haystack.

It is unlikely that there was a sudden increase in 2016, more likely we had not spent enough time monitoring in previous years.

Suffice to say, we are now optimistic that Edgecombe flats will grow into a major colony of both Swifts and House Sparrows. The success of this project should encourage other councils to do similar things. Projects like Fulbourn and Edgecombe show that it is all worth while.

The plan now is to inspect all of the boxes and do some maintenance, such as further wood treatment and reduce or possibly remove some of the House Sparrow nesting material.

Entrances cast in situ

When Barbara Wager, of Thorpe in Derbyshire, contacted us about how to provide Swift accommodation in a stone wall, we discussed various ideas, ending up with making entrances by casting them in situ.

This is a small-scale rerun of the Alcázar of Segovia project, where we, AfS provided formers, and the rest was done on site. In this case, the wall is 2 feet thick. The entrance leads to a natural cavity in the stonework, without any need for a nest box. The cavity is sealed with a board.

These pictures explain exactly how it was done:

Santon Downham Church

St Mary the Virgin, Santon Downham, in Suffolk is in a very attractive setting on the edge of the village green

It also has the easiest belfry that we have seen for installing Swift boxes. There is even a solid floor to stand on while working on the boxes!

In the lower half of the picture, left, it can be seen that the louvres are flush with the sides. This makes it very straightforward to screw the boxes to the sides.

Bill Landells has done an excellent job installing 18 boxes in 6 cabinets on 2 sides of the belfry, 3 on each side. All with access doors for inspection.

There is the potential for 2 odd-shaped boxes above the top cabinet. As Swifts always seem to go for the tops of the louvres first, this may be something worth pursuing in the future.

Swift boxes on a thatched cottage gable

There are no new ideas here, but it demonstrates that, with a little thought, Swift boxes can fit in well with the appearance of a pretty village cottage.

[UPDATE August 2016 - one pair seems to be established in the bottom right box]

Great Wilbraham is an attractive village just 2 miles from Fulbourn, the home of one of the largest and most successful Swift nest boxing projects in the UK. Great Wilbraham itself also has a healthy population of Swifts.

The design, with 5 nest chambers, is another version of these designs (Elsworth, Reach)

Swift Action Harleston - Swift mobile

We were delighted to receive this story from Harleston in Norfolk. The local group, Swift Action Harleston has come up with a great idea that could be replicated anywhere.

The mobile was produced from hundreds of cut-out Swift shapes by pupils at Harleston Primary School. Each Swift is decorated with a design based on the colours of the flags of the Southern European or African countries through which the Swifts fly on migration and carries an individual message to the Swifts from the pupil that made it.

The pictures below show close ups of  some of the designs in the mobile which are all being combined and turned into flags for display in the town.

One of the delightful messages reads:
"Dear Swifts ... never give up, never give up. If the weather knocks you down, get back up, never give up, you can do it. Please don't die."

Isn't that nice, and here are some pictures of their spectacular mobile:

New Swift nest sites in the Alcázar of Segovia

When we met Javier Saez Frayssinet in Szczecin, we discussed an idea of how to transform irregular holes in walls into entrances suitable for Swifts. We, AfS, had developed a method suitable for casting entrances in situ. The result of this conversation is most gratifying, with 60 new nest sites, so far, being incorporated in the walls of the castle, it may well end up with over 100 new nest sites.

The Alcázar of Segovia. Photo Wikipedia
The Alcázar of Segovia is spectacular (see Wikipedia), and a wonderful setting for a Swift colony. There were many holes in the walls with the potential for turning them into Swift nest sites. Javier took our idea and used it innovatively to fashion attractive entrances in the walls of the castle.  

The method uses a 'former', an object the same size and shape as a Swift entrance.

2 formers
Inside each entrance is a space at least 15cm x 30cm.

The idea is a development of the Cambridge System, but instead of pre-casting entrance pieces, entrances are created in situ in the wall using the formers.

In this project, pieces of terracotta have been used, allowing the formers to be redeployed before the mortar has fully set.

The pictures below show the results.

Beijing Swift Project 2016

On Saturday 21st May, we undertook the next stage of the Beijing Swift Project at the Summer Palace, here in Beijing. 

Some of the team
We succeeded in catching 10 birds with geolocators. 9 of these had good data, 6  from birds tagged in 2015 and 3 from birds tagged in 2014. 2 of these we had caught in 2015, but one was a new bird carrying 2 years worth of data.

So we now have 23 complete tracks, 14 of the 2014/15 migration and 9 of the 2015/16 migration. 

Preliminary analysis shows the birds doing similar things, with some interesting differences, in the 2 annual cycles.

The following is a video animation by Lyndon Kearsley of the results of the 2014-15 migrations. The gaps in the anmation occur in the periods near the equinoxes:


We also succeeded in fitting 46 new loggers of various types: GPS loggers, loggers with accelerometers and pressure sensors, as well as some more light level geolocators. These should give us more valuable information in 2017.

This year, the team comprised Lyndon Kearsley (Belgium), Susanne Åkesson (Lund University), Chris Hewson (BTO), Terry Townshend (Birding Beijing), Wu Lan (Beijing Forestry University), Robert Jolliffe and Dick Newell (Action for Swifts), as well as about 60 people form the China Birdwatching Society and Beijing Normal University led by Professor Zhao.

"I am a Swift" now in Dutch and Greek

Since the recent adaptation and translation into French, we have now received copies in Dutch and, from Cyprus, in Greek.

Click to enlarge

Since we produced "I am a Swift - I am in trouble", in 2011, we did a second edition in 2015. There has been an Irish adaptation, called "We are Swifts - we are in trouble" as well as a French Version, and now it is in Dutch and Greek.

We are naturally delighted that an idea conceived by Helen Hodgson back in 2011 has now received such wide acceptance.

Our second edition is now out of print, and we are planning a 3rd English edition.

For the various editions, you can contact:

Sedbergh Community Swift project at St Andrew’s Church

When Dick went up the church tower with Edmund at St Andrew’s, Sedbergh, his comment was that ‘this is the most difficult tower I’ve come across yet. Pity it’s your first!’ The church is a good location to try, however, as swifts nest not far away in the eaves of Sedbergh School library. 

by Tanya & Edmund Hoare

St Andrews, Sedburgh 
And undeterred we went ahead, even though the design of box required was rather complex, and needed entrance tubes for the swifts.  The tower is not boarded on all sides. 

Luckily we had fantastic help from Nick, the local vet. Without his super carpentry skills this project could not have been accomplished.

Over the winter he and Edmund have spent many cold hours up the tower working out what to do. But finally the boxes have been installed behind the louvres of the west side, and an attraction call system has been fixed too.

The boxes could be fitted with cameras later.
All we need now is swifts!

The entrance tube is there to get through 2 layers of netting to the outside world

Internal Swift boxes in a difficult situation

We have had external Swift boxes on our 17th century house since 2004, with 9 pairs in 2015. Being a listed building, the scope for internal boxes is limited, with just one possible location at the top of a gable end which was built about 50 years ago to replace what was a wooden dairy. 

by Dick Newell

There is no possibility of access to the roof space behind the gable. However a test hole showed that there was a cavity 100mm wide behind Dutch bricks 110mm wide. So, I reckoned we could fit a nest box spanning the cavity and 8cm of the outer wall, giving a floor area of 18cm by 25cm - big enough for a Swift box.

The wall is constructed of nicely selected reclaimed bricks of many textures and colours, so the challenge was how to produce forged brick entrance pieces which look the same.

I eventually took the plunge and we removed one brick from high up in the gable and cast a whole brick insert, 3cm thick out of white cement. A nest box was assembled in the cavity, ship-in-bottle fashion, out of cement fibre-board and glue. This is another variant of the Cambridge Swift Box System.

The internal length of the nesting chamber is 30cm in the cavity and 25cm in the outer wall. The head room is 14cm in the cavity and 7cm in the outer wall.

The first box we deemed a success, so 2 more bricks were removed and 2 more inserts were used, one made of a mixture of white and grey cement and the other the same, coated in crushed red-brick .

The 3 inserts looked a little different from the bricks around them, but with a judicious use of a used tea bag, coffee spread with a finger, and cement powder dotted liberally over the surface, a very good match was achieved.

If the Swifts like these first 3 nest boxes, then there is scope for at least another 2 boxes.

Much of the credit for this goes to Bill Murrells and his remarkable brick laying skills.
